Corporates failing to make circular economy transition, damning report finds

While this is discouraging it should be noted the need of the hour is a fundamental shift in the way humanity addresses the wants and needs. Circular economy is a another word being used to reinstate 3Rs. Circular economy would be successful ONLY when we accelerate the reduce and reuse of materials which implies that the needle of responsibility points at several others beyond corporates and businesses. It should begin at the household level where the children are encouraged, advised and coerced into reusing everything possible through awareness, crafts and skills. This strong foundation is bound to direct the society towards circularity. A good example is the Japanese principle of Mottainai which believed in wasting nothing and reusing everything . This word was used in every household in Japan for several decades in the aftermath of the war to caution the children not to waste anything be it paper or a piece of cloth; not to forget thefood.

Net-zero in the public sector: What might it mean for business? - The ADE blog

Hi Joanne It''s time to shine a light on schools'' carbon reduction..or lack of it. Since schools account for about 60% of public sector carbon emissions this is clearly where the biggest opportunities and challenges exist. But there is no overall carbon reduction strategy for this sector. Why and what do you think we should do about it? One headache is academisation which means it is very difficult to engage with schools in the many multi academy trusts or MATs rather than local authorities. One thing that is certain is that meeting any public sector carbon sectors can''t be achieved unless schools become part of the answer rather than the problem. Maybe the school strikers for climate should be striking against their own schools for not taking action!! Thanks Steffi

UK's first 'smart' commercial hub signs 50-year clean energy innovation deal with E.ON

The ultimate sources of renewable electricity in the commercial field have been obscure. How can wind generation, the principal source provide all the power when it drops to a GW or much less, for days on end. With solar nil overnight, this must be impossible. This quote comes from The Telegraph: "These certificates let firms market their tariffs as completely green, when they might actually be buying electricity from a coal-fired power station. Now, industry insiders say that instead of buying these certificates from UK renewable generators, energy suppliers are purchasing them from Lithuania, the cheapest market for REGOs in the EU. "This is the first time that the existence of a European market for cross-border green certificates has been revealed. It is unclear how many UK energy suppliers have engaged in this practice, although a source said that at least two companies they had worked for had bought dirty REGOs, and described how uncomfortable it made members of staff at the time" Richard Phillips

Horizon scanning: Eight innovations set to shake-up sustainability in 2020

One of the key things we need to do is stop wasting energy not just by being more energy efficient but also by stopping the use of energy to manufacture stuff we just don''t need. Far too many products manufactured end up in landfill in a matter of months if not days in some cases. This is hugely wasteful of both energy and resources. Built in obsolescence needs to be stopped. In a world of finite resources manufacture and use needs to be in sync with cycles of renewal and the circular economy needs to reflect ecological cycles. Do we really need all this stuff?

Priceless Planet: Investor coalition pledges to plant 100 million trees

Tree Planting by Drone Could Help To Reach UN Target of a Trillion Trees DENDRA, the makers of Sky Tractors (drones) say that they can plant 150 times faster than conventional methods and in hard to reach places, the land is scanned to ensure that the germinated seed pods are not wasted on such things as rocks and water, before planting starts, the Sky Tractors can be then flown several at a time (if the country permits this) for maximum speed. I have been in contact with Susan Graham CEO with a view to getting the Sky Tractors to plant in equilateral triangles in order to increase crop production by 15% (see Crow''s Footing page). My friend Don Shaw from Australia says: Woke up 2am to smell of smoke drifting from fires, Sounds bit like a California scenario. and sent a photograph he took of the flames sky high. In the climate crisis land use is going to be critical, and also, tree rings around cities, towns, and villages, will keep the area cooler as trees give off water vapour, I have already got Google to cool their servers with trees, it works out cheaper than conventional electrical cooling. Beijing does not have to be the only city with a ring of trees. The Drawdown book edited by Paul Hawken recommends silvopasture, which is planting trees in fields where animals graze, this provides shade, sequester carbon above and below ground, and cut farmer''s costs for feed, fertiliser, and herbicides, it could save 31.19 gigatons of reduced CO2 for a cost of $41.6 billion with a saving of $699.4 billion. Managed grazing can also help. By breaking up fields into smaller areas with fencing, and then moving the animals on regularly the grass is not over cropped and gets time to grow back. Drawdown estimates that this would save 16.34 gigatons of CO2, would cost $50.5 billion, and would save $735.3 billion, so another obvious weapon in the hands of environmentalists.

Businesses not examining carbon impact of plastics alternatives, edie survey finds

"The road to Hell is paved with good intentions" Unless the entire chain of a product is examined it is folly to call something "green", "greener", "low carbon" or "environmentally friendlier". Take the paper bag. You need petrol to power the chainsaw to fell the tree, diesel to power the equipment to move and load the trees, diesel lorries to transport the tree to the sawmill or paper mill, power to operate the mill to create the paper and so on. How much oil is required to make a paper bag? How many plastic bags can you make from that oil? Are paper bags "greener" than plastic, especially if facilities exist to recover the plastic and turn it into something else (possibly more durable and long lasting). The danger is we "knee jerk" react and end up with a worse problem than the one perceived to be the problem. The biggest thing we can all do, with everything, is simple really. We need to reduce our wastage and end consuming for the sake of consuming

BBC's bumper climate coverage and plastic-free snacks: The sustainability success stories of the wee

I hope the BBC will give a balanced, scientifically accurate approach to its "Our Planet Matters" coverage but I''m not going to hold my breath. Science doesn''t get ratings; hysteria, hype and mythinformation does. and when was the last time anyone let facts get in the way of a good story. And why the negative slant of UAE investing in nuclear? Nuclear power is clean and once the power stations are constructed it is zero emission and No Carbon. Run properly with strict control protocols it is the safest form of high demand power we have access to. And the only one that can constantly supply the so called "baseload" for a countrywide grid.

UK's first grid-injected hydrogen trials begin in Staffordshire

The whole idea of this is utter stupidity... As you both have highlighted below the thermal-dynamic mechanics of this is useless. All this excess power they speak of cant just be ramped up and down that quickly as the power plants are now the balancing mechanisms to prevent over or under voltage/frequency of the grid through uncontrollable renewable energy output. Fuel cells require rare earth metals, very expensive to produce. to create the hydrogen from the excess power they speak of will require 150% more generation on the grid, not counting the energy density of hydrogen compared to other fuels. Electric Cars complete waste, consider the 33 million cars in the UK converting to electric now draw 3kw each to charge! Thats almost 100Gw of power the uk grid only produces 45Gw currently not to mention the amount of extra cabling in the ground that required upgrading to transmit it. Now look at the fact that the round trip efficiency of hydrogen is 70% efficient to produce so that power requirement will be even greater!!! Ill leave it the ill informed politicians without our a scrape of common sense to work the rest out of how their going to send the world into darkness. Maybe Greta Turdburg has the answers ?

Government urged to target one million heat pumps a year by 2035

Nigel - I think the problem is councils and housing associations are basically "ticking a box" by installing ASHP in their housing stock without taking the building standards, customer needs or anything else into account. From what I understand from the lady whose electricity bill went up 4x no one had even been to her house to inspect it before the ASHP was installed. They just bolted it on and ticked the box to meet an arbitrary "eco" target. With all the talk of low carbon and renewable people forget that while the heat source is renewable the compressor and pumps take a fair amount of electricity to power them. At 15p/kwhr you have to get 4x more heat than the electricity used to match the cost of oil or gas fired CH. In winter, at single digit temperatures or below, how much heat can an ASHP extract per unit of electricity? I''ve heard talk of as little as 1kw of heat per kw of electricity which is hardly effective or efficient. As I have said previously when properly designed, installed and fit for purpose, in a properly insulated, energy efficient building Heat Pumps are a valuable addition to the heating options but when they are just thrown on an old, leaky, draughty house to meet a KPI they are totally worthless and completely useless.

Government urged to target one million heat pumps a year by 2035

This is a useful discussion and I''m glad I shrugged off my usual reticence to pick an argument. Interesting point about the cost of the power supply going up so much that it rendered the ASHP installation economically unviable. I have also heard that from a contact who used to work with housing associations, where the ASHPs that had recently been installed all had to be removed again, because the tenants could not afford the electricity bills any longer. But arguably that issue arose because of incorrect specification in the first place. Totally agree with Keiron that it will all depend on proper oversight, to ensure no shortcuts and to ensure that specification, design, build quality etc are all correct. Maybe the various UK heat pump trade associations should be banging that drum alongside the perfectly reasonable argument that we need to escalate the rate of deployment of heat pumps. (I am just a retired tank commander and trouble-maker, by the way, so have no axe to grind in this matter).

Barry - You are correct that most, if not all problems, come from incorrect design or installation. As I said when they are built in from the start, correctly sized and designed for the building then Heat Pumps work brilliantly. It is just Thermodynamics and you can''t argue with Physics. The danger with this urgent target is we might manage to install 1 million Heat Pumps but without oversight and Quality Control 999,999 of them will be unfit for purpose, badly designed and inefficient which completely defeats the purpose. It is exactly like the lack of oversight and QC in the building industry that is allowing modern homes to end up with thermal bridges, gaps in insulation, gaps and draughts despite the standards stating that modern houses should achieve a minimum energy standard. Slapping a solar panel on a North facing roof shouldn''t mean a box can be ticked. Andy - never heard of CO2 being used as a refrigerant I have to admit and the only Heat Pump I have ever seen for HW used R-132 (an HFC) which proved to be unfit for purpose when I tried it as it took 26hrs to heat my water tank (assuming I actually didn''t take any HW out of the tank!!)

Government urged to target one million heat pumps a year by 2035

Kieron re: elephant in the rooms for heat pumps -> CO2 heat pumps do not use refrigerants. However these are mostly used in DHW applications, not for continuous heating.

Government urged to target one million heat pumps a year by 2035

"Seems to me that the key requirement is to get the specification right and then ensure that the system is installed as specified." is entirely correct. As an installer of ERP A++ ASHPs on a UK offshore (subsidy free) market, one also knows first hand how the problem installations can occur - it''s almost always down to incorrect design. With regards to age of buildings, insulation levels - it really is irrelevant to the type of heat source, It is the rated output of the Heat Source and the way the Heat Source Delivers the Heat. The above is In relation to (but not limited to) positioning of equipment, available electrical power supply, pipe sizing & flow rates, heat emitter surface area etc. On a retrofit refurbishment installation, a new ASHP installation easily competes with a new Oil fired installation. On an existent retrofit, on average (in the local market I am based) at least one radiator usually requires replacement, to enable a Heat Output operating at Flow Temperatures optimal for ASHP efficiency (optimal Co-Efficient of Performance) along with a Heat Pump rated Hot Water Cylinder. My house was built in 1890, and the Heat Pump works fine. However every installation has to be assessed prior, as the old methods of Boiler sizes being literally guessed no longer applies.

A Plastic Planet: It's time for activism on climate change and plastics to collide

The problem of domestic plastic waste disposal has two elements. The first is to persuade house holders to separate their plastic waste into a separate container, and secondly to oblige the waste disposal companies to separate this into true waste and recyclable products. This may be made mandatory There are, however some 39 companies, and little if any option to bury the non-recyclable material. Government policy is, however to put the realisation of such activity into private hands, indeed it is mandatory. This is totally unreal since the most profitable operations will be chosen, having a maximum return on investment, cherry picking, in fact. If this hurdle can be overcome, I would suggest that items such as the familiar milk bottle (HDLE), and the clear drinks bottle (PET) should be all be recycled. Products of indefinite or mixed composition, are most easily burned to generate power. The drafting of whole policy should be include staff with the relevant scientific knowledge and experience, qualifications absent from the upper echelons of Government, and sparse in business circles Strong science oriented action is required. Richard Phillips

Government urged to target one million heat pumps a year by 2035

To Keiron. It seems a big jump from ''only truly effective'' to ''absolutely useless''. I''ve heard the ''absolutely useless in existing stock, especially old stock'', many times in the past couple of years. But there is also plenty of empirical evidence that indicates the opposite. It''s not that long ago that I went to a relatively leaky, old listed house that was functioning perfectly well on GSHP. A fossil fuel back-up had been retained, but not used since the system was installed a few years previously. Seems to me that the key requirement is to get the specification right and then ensure that the system is installed as specified.

Government urged to target one million heat pumps a year by 2035

Nigel - I can only quote from what other users of these systems have said. One lady I spoke to about an ASHP told me she was now paying 4 times as much in electricity to heat her home since the council installed an ASHP and the house was still cold and now damp. Hardly an effective heating system. Another person who installed ASHP has had it removed and the oil boiler reinstated as it was costing more to heat the home and hot water with the ASHP than with the oil boiler. Again hardly effective and their''s is a fairly new build house (less than 20 years old). I''ve heard other people say they wish they''d never installed ASHP and I know of one person who installed a GSHP only to find they now have to use the electric immersion to provide a tank full (200l) of hot water every day as the GSHP can''t heat the water enough. Properly designed, installed and with a properly insulated (PassivHaus?) building yes Heat Pumps are effective but in our ageing, leaky, poorly insulated housing stock (particularly council/housing association stock) they are proving to be increasingly bad choices and I am yet to be convinced how efficient they are in the Highlands where temperatures are often low throughout winter when you need the heating most.

Government urged to target one million heat pumps a year by 2035

Heat Pumps (be they Air, Ground or Water sourced) are only truly effective in properly built and insulated buildings with fit for purpose heating systems. They are absolutely useless in most of our current housing stock, even houses built to modern standards leak like a sieve. With virtually no quality control on builders there is no way to say for sure if insulation has been installed properly or that modern housing will actually meet the energy efficiency standards stated. Evidence shows that modern buildings can be twice as energy hungry as the certificate says. Older housing is even worse even if you do add double insulation. I have found at least 2 locations in my house where insulation is totally absent in areas where I have no chance of ever installing it retrospectively. Plus to fit a Heat Pump retrospectively in my house requires a complete overhaul of my "wet" system at a cost of about 18k for the GSHP and 5k for new pipes and radiators to give me a central heating system that may not actually heat my home enough. Then there is the elephant in the system with Heat Pumps. The fluid they use to extract the heat and transfer it is a Hydro Carbon. Or more correctly a Fluoridated Hydrocarbon (HFC). Made from oil and a potent Greenhouse Gas. While in normal use this is not a problem if it leaks it becomes a climate change problem. And 1 million Heat Pumps need a lot of refrigerant to work which means oil. So while they can be effective and are a source of low carbon heat they still need a lot of oil for their construction and operation so don''t call them No Carbon

VOTE: What will be the defining sustainability issue of 2020?

Whilst I think plastics will continue to dominate the media, I think we should be devoting effort to nature conservation and restoration. Until we begin to restore our world to its more natural state (if that will ever be possible) we will continue down the rocky path to devastation. My personal view is that working on this element will naturally lead to improvements in other areas of concern. I am not a great fan of extensive banner-waving as this focuses on one aspect and the full picture is never truly given. We are now reading that alternatives to plastics can have a bigger impact than plastics. This is not a surprise to me but I do know it is to others. This is certainly going to be a challenging time and I would love to see people working together to rebuild our natural world.

Decade of ascendency: New hydrogen fuel cell capacity surpassed 1GW in 2019

It is actually DAVID Hart. With regard to hydrogen: HYDROGEN Much speculation has been made recently upon the possible advent of an economy using hydrogen as a primary source of energy. Consideration has, however, to be made of the physical characteristics of the gas before speculation upon its place as a fuel for any purpose. Occurrence. Hydrogen gas does not occur in nature. All gaseous hydrogen has been long lost from the planet, due to fundamentally low level of the planet's gravity. The most abundant source of hydrogen is as its oxide, water. The other principal source of combined hydrogen is in organic material. Organic chemistry has been described as the chemistry of carbon, but equally valid would be the title "The chemistry of Hydrogen". It is of primary importance, in the commercial use of hydrogen that it does not occur in its elementary state. All hydrogen, for whatever purpose, must be manufactured. This involves energy, in inefficiencies, which is never recovered in its use, and may be as great as 30-40%. Fossil fuels, however, occur naturally with their potential energy as fuels, already in them. The extraction and presentation of fossil fuels at the point of use, requires only a small fraction of the amount of the energy obtained in their use. This is a huge advantage. [It may be observed in passing, that the "Thorium Reactor", so often lauded in the Commons, suffers a similar disadvantage. Thorium is not a fissile element, but has to be irradiated with neutrons in a reactor to convert it into U233, a non-naturally occurring isotope of uranium. The fissile element of uranium used in all reactors as the fuel, is U235, when more is needed, it may be mined and separated. But there is much more thorium available that uranium. See also OKLO] Methods of isolation. All methods of isolation of hydrogen involve the expenditure of energy. The quantity of energy expended in any process will inevitably be greater than the energy recovered in its use. This use will almost uniquely be its oxidation to water. Electrolysis. The passage of a direct current through water containing an electrolyte, results, under controlled conditions, of about 80% of the electrical energy being used in the electrolytic, process. Gaseous hydrogen is evolved at cathode, and oxygen at the anode. Commercial units have been developed the using this process, producing hydrogen at high pressure. The high pressure is reflected in a higher consumption of power than would be required at normal pressure. There is no free lunch. The source of the electricity must, if decarbonisation of the fuel cycle is the intention. be from a non-carbonaceous source. Currently this is cited as a renewable generator, primarily wind. This has the disadvantage of wide variability. Any consequent production of hydrogen from a plant of given capacity is reflected as plant inefficiency. A demand lead source is thus to be preferred. The only candidate for this function is nuclear generation. Methane Reforming. This is a commercially widely used process to convert naturally occurring methane into carbon dioxide and hydrogen. This is achieved by reacting it with steam at a high temperature, followed by a lower temperature catalytic reaction. The CO2 is removed by pressure variable adsorption. Industrial quantities of hydrogen are produced by this process, but the disposal of the residual CO2 has to be addressed for these purposes. Again, it is an energy adsorbing process. Iodine/sulphur thermocycle This process involves the thermal decomposition of water into oxygen and hydrogen. The water is fed to a mixture of iodine and sulphur, which is successively heated and cooled between about 850oC and 450oC, water being added as it is decomposed. The cycle results in the evolution of oxygen at the lower temperature and hydrogen at the higher. In practice, the operation is complicated by the high temperatures demanding materials resistant to aggressive conditions. The potential benefit lies in the potential use of the high temperature reactor, as a pure heat source. Practical Considerations Its physical properties do not make hydrogen attractive as an energy source. When compared with natural gas, methane, volume for volume, it "contains" about only one third of the energy. As a consequence, a domestic central heating "boiler" would require three times the volume of gas. This would have to be reflected in either gas pipes to be replaced by larger diameters, or for pipe pressures to be increased, over the whole system. The latter would exacerbate both diffusive and simple leakage losses of an expensive fuel. The alternative is electrical central heating. Storage heaters may be used, or the more thermally efficient "heat pump". The scale of electricity generation needed for a country-wide adaption would require nuclear energy, such a scale of renewables is not practical. (Over and above this need there is the total replacement of petrol and diesel fuel) To supply Heathrow with hydrogen aircraft fuel, it has been estimated, would require reactors about three nuclear power stations, some 3GW. Water supply would have to be substantial. Liquefaction of hydrogen is difficult, the processes required falling into the extreme end of cryogenic techniques. Liquid hydrogen has a specific gravity of only 0.07, a large volume is needed for its storage. It is also the reason for proponents of its use as an energy source only ever quoting its energy density in terms of weight. Richard Phillips

Massive rise in EV charging points needed to reach EU climate goals, analysis finds

Or we all need to radically rethink our personal, private transportation options. Electric Vehicles are not the panacea everything says they are. They still need huge amounts of resources to build, including Rare Earth Elements and Hydrocarbons. They still need huge amounts of power generation to charge the batteries. They still create congestion. They still create particulate matter (tyre dust for one). Designing and building new single and twin seat vehicles (town cars, "smart" cars, bubble cars, scooters) instead of massive 7 seater people carriers and luxury 150mph SUVs would help but can we all "afford" to keep having a 5 seat vehicle for daily transport when the vast majority of journeys are within towns and cities and under 10 miles?

British Airways begins offsetting domestic flight emissions in first step towards net-zero

The Range of an Electric Vehicle Could be Better than a Fossil Fuel One, Clean Long Range Transport is a Real Possibility Professor John Cushman, Co-founder, IFBattery A new type of electric vehicle power using refillable technology has taken another giant leap in advancing alternative energy with testing that shows it could provide enough energy to run a car for about 3,000 miles. The technology employs a novel type of flow battery that is being successfully tested in golf carts. The jump that this technology has made in the past two years is a testament to its value in changing the way we power our vehicles, said John Cushman, Purdue University Distinguished Professor of Earth, Atmospheric and Planetary Sciences and a Professor of Mathematics. It s a game-changer for the next generation of electric cars because it does not require a very costly rebuild of the electric grid throughout the US. Instead, one could convert gas stations to pump fresh electrolyte and discard depleted electrolyte and convert oil-changing facilities to anode replacing stations. It is easier and safer to use and is more environmentally friendly than existing battery systems. The technology uses a patented technology that is safe and affordable for recharging electric and hybrid vehicle batteries by replacing the fluid in the batteries about every 300 miles through a process similar to refuelling a car at a gas station. Every 3,000 miles, the anode material is replaced, taking less time than is needed to do an oil change and costing about the same with an estimated cost of about $65. It is the full circle of energy with very little waste, Cushman said. IFBattery s components are safe enough to be stored in a family home, are stable enough to meet major production and distribution requirements and are cost-effective. The used battery fluids or electrolytes can be collected and taken to solar farm, wind turbine or hydroelectric plant to be reused again. It is the full circle of energy with very little waste, Cushman said. This makes for a lighter and more efficient EV, and I look forward to a production car coming out at soon as possible. It also means ships and lorries could become clean, and possibly aircraft too. https://www.youtube.com/watch?time_continue=12&v=FdM2b4cZULg Yours faithfully Andy Kadir-Buxton ''RedRoseAndy''

The crisis in food systems goes well beyond simply the meat vs plant debate and goes to the fundamentals of how we produce our food. Much of the plant-based food we eat relies on commoditised industrial farming systems which promote monocultures and practices that degrade the soil, landscape and are significantly contributing to habitat and biodiversity loss. There needs to be a wholesale shift in approach to food production that promotes regenerative farming practices that nourish and protect supporting ecosystems, re-engages consumers with an understanding of how and where their food comes from and allows food producers to escape from the pressures of the stock broker and multinational corporate driven production paradigm by strengthening links between producers and consumers, fostering the appreciation of food value and re-embedding externalised costs into the system.

The problem is that in order to build solar panels or wind turbines you need oil based products.

Even insulating electric cables takes oil based chemicals so does building the casing of electric batteries and a lot of the interior of an electric vehicle. And Greta''s transatlantic yacht used a huge amount of oil based materials in its hull, sails, rigging, fridge, life saving equipment. Damned if you do and damned if you don''t for the oil companies. While we can''t continue to burn it as a fuel we still need it for everything we want and need in our everyday life.

Horizon scanning: Eight innovations set to shake-up sustainability in 2020

It seems to be little appreciated that hydrogen has drawbacks! Primarily, this is its source; it does not occur naturally as a free gas. To obtain natural gas, with a high calorific value, we drill a hole in the ground and obtain a supply of energy much greater than that required to drill the hole. To obtain a supply of hydrogen, ALL the hydrogen has to be manufactured from energy which we have to generate. This involves inefficiency losses, as well as just the equivalent amount of energy in the amount of hydrogen generated. Its use involves further inefficiency losses. Overall it is an energy expensive route. It is merely a storage system, not energy beneficial. And it will prove very expensive. Like CCS, storage, and the never-mentioned-addenda to renewables, it will be very costly. In addition, volume for volume, when compared with natural gas, it has only about only third of the NG calorific value. I wonder whether the senior businessmen of the organisations involved are fully aware of the down-sides revealed by the science and engineering involved??? Certainly politicians and the media are woefully uninformed. I suppose my next stop will be in the Tower!! Richard Phillips

UK's first grid-injected hydrogen trials begin in Staffordshire

Ken I know what you mean but that is the risk one takes as a scientist, and a Geologist at that. The "greens" mean well and have the right idea at heart but as we know the "road to hell is paved with good intentions". Unless it is scientifically and engineeringly sound it doesn''t matter how green an idea sounds a bad idea is a bad idea no matter what the "colour" of it. We have to be wary of "knee jerk" reactions as when you look closer often the so called "green" option is worse environmentally than the problem it is trying to solve (Electric Vehicles may be one of those cases in my humble opinion). Always good to know there are others out there, like me, who aren''t going to take "green" propaganda at face value but will research and look at the big picture.

Ken I wish!! You are right though that our leaders generally have no or little scientific or engineering background. The have advisers but then decide to ignore the advice and do what they want anyway. We are the willing, lead by the unknowing, doing the impossible, for the ungrateful as the saying goes. It is through organisations like Edie and others that we might, possibly, have a chance to inform not just our MPs but also the "sheeple" that not everything green is really green and that science, particularly the laws of physics, can''t be changed. Yes Energy can neither be created nor destroyed, merely changed

Keiron, Please assure me that you have the ear of government on this matter! It seems we are led by people with no mathematical or engineering understanding - which would be fine if we had a numerate and technically competent civil service. Dominic Cummings seems to believe the latter is not true and I have reason to believe he is right. Meanwhile, we must not give up and need to inform our MPs of the truth about "greens" and the implacable laws of thermodynamics...

UK's first grid-injected hydrogen trials begin in Staffordshire

Ken, The Hydrogen - Oxygen bond is extremely strong so takes a lot of energy to break. I used to use a Hydrogen Generator to produce lab grade Hydrogen from distilled and deionised water and it does use a lot of power to produce the gas plus a lot of chemicals to purify the water too. While yes it is a net negative result if it were done locally for local gas grids then the fact the entire gas infrastructure would not need to be replaced or substituted would means overall it would be effective. But it isn''t suitable for the National Gas Grid. The amount of electricity needed to provide that much Hydrogen would be better utilised as the primary source of energy to heat directly. Sadly a lot of "green" sounding ideas are total garbage when you really look into them. Hydrogen might have a future as a small scale heating fuel but the numbers just don''t add up. Particularly if it is produced from Natural Gas.

UK's first grid-injected hydrogen trials begin in Staffordshire

Keiron, I think we are of one mind on this, but I did not expect you to claim that the energy needed to liberate H2 is greater than available in the H2 that is so liberated. A negative sum, therefore not worth doing. I was at a conference in London last year where someone proposed piping hydrogen across the S Wales valleys, as a "clean" fuel source. Great idea - where did the H2 come from? Cracking methane in Milford Haven, having been shipped in from Qatar. Oh, that meant he needed CCS for the CO2 created. Never mind the energy required to split the methane. And he was treated as a sensible engineer!!! Not sure about AD for food waste. Too much capital, too much digestate to go back on farms when they don''t need it, and why not feed it to pigs, like we used to? The digestate is "sterilised" before it goes on to land anyway. Do that properly to the original food and you have "safe" pig swill - and much less bother! My PhD was in ag eng and water pollution from pig slurry...

UK's first grid-injected hydrogen trials begin in Staffordshire

@Ken - Hydrogen can be made by hydrolysis from pure water as you say but also by cracking Methane (CH4) to give 2H2 and CO2, which coincidently enough is also what you get when you combust Methane (well the H2 is bound up as Water but that is the end product of burning Hydrogen anyway). H2O is also a potent greenhouse gas. The problem with both is the amount of energy to achieve this is far greater than the energy returned from the Hydrogen, unless you turn it into an H bomb of course. In the case of the Methane derived Hydrogen this negates the point of the Hydrogen as you get the same end products and much more energy from the combustion of the Methane directly. So cut out the middle man and don''t bother with Methane derived Hydrogen as it is energy inefficient and just as "high" carbon as burning gas.

UK's first grid-injected hydrogen trials begin in Staffordshire

I note that neither this article nor the one from edie''s "In Practice" strand, makes any reference to the source of hydrogen. Roger Harrabin has said on his BBC News feed that it will be generated from water by hydrolysis. The electricity for this operation will come from "surplus" wind generated electricity, where the supply exceeds the demand. No reference as the the energy cost of that process, to discount against the energy content of the gas used for the grid. On the other hand, one might not need 25 million new domestic boilers. They will each just need conversion, taking between 30 and 60 minutes. Quite a job...

'Cleanest year on record': Zero-carbon electricity surpassed fossil fuel generation in 2019

Hi @Colin Matthews, BEIS''s Digest of United Kingdom Energy Statistics (DUKES) has information in this depth. However, it takes longer to put together than the National Grid''s data (due to the level of detail) and therefore only has data up to July 2019 at present. National Grid may be able to provide more up-to-date info if you contact them directly. Best, Sarah, edie.

'Cleanest year on record': Zero-carbon electricity surpassed fossil fuel generation in 2019

This could serve to deceive. Can we have a breakdown by season ie Dec to Feb, Mar to May etc as that will give a clear indication by changing energy demand. Also the average daily GW requirements for each month. Would then have a true picture of what is truly achievable.

UK's first grid-injected hydrogen trials begin in Staffordshire

The problem with Hydrogen, which I will keep saying until the "greens" listen, is it takes more energy to make it (from water or CH4) than you get back by burning it or using it in fuel cells etc. And if you make it from Methane it is not a zero carbon fuel at all. Not only that it leaks from every single pressure or storage vessel we have (I know from personal experience in a lab environment) so you can not keep it for long term storage. However, if the Hydrogen can be created from "waste" water (unlikely as you need pure, deionised water ideally) using dedicated clean electricity (rather than the so called "excess" people keep going on about) on an "on demand" basis and it can be bled in to a local gas network that uses biogas from waste food (Anaerobic Digestion) then maybe we could be onto a winner. Think about it for a moment; local waste food turned into biogas, mixed with local Hydrogen to heat local homes. Not only do you get rid of a waste stream but you massively reduce emissions without having to totally replace every central heating system in the country. That''s a huge financial saving. Now all we need to do is find some way to turn waste food into bio kerosene for those of us who don''t live on the gas grid.

'Promises are not enough': Green economy reacts to Boris Johnson's historic election win

A 10 kilometre deep lined and capped water well can convert all power stations to clean energy, a cut of 30% in CO2 emissions. A 20% cut would come from electrification of all vehicles. 41% would come from coating all buildings in Starlite. Aircraft and Ships could halve emissions by using fuel mixed with water using an ultrasonic dibber. Aircraft account for 6% of CO2, while shipping accounts for 4.5%, so another 5.25% can be saved. The total savings would then be 96.25%. Improving soil using biochar would then cut CO2 in the atmosphere by locking it in the ground. Cement based on magnesium silicates, not only requires much less heating, it also absorbs large amounts of CO2 as it hardens, making it carbon negative. It can all be paid for by eliminating mental illness using the Kadir-Buxton Method.

General Election result: Conservative landslide victory raises fresh concerns for green economy

Like most environmentalists, I am very nervous about what an incoming Conservative administration may do, especially without the guiding hand of EU legislation. However, we should recognise that there are opportunities as well as threats and that all parties committed to combatting climate change. Although billed at the start as the "climate emergency election", the lack of serious discussion probably prevented the Tories retreating into a defensive corner. We should therefore seek to engage the new Government, pointing out the benefits from being a world leader in this area (soft power), and focusing on solutions that will create a more robust green economy. On the energy front this must mean a greater emphasis on demand reduction and smarter networks to manage renewables effectively, rather than seeking reliance on nuclear power or CCS. Empowering local action to address future energy needs fits well with the prevailing sense that the decision-makers "out there" (whether in London, Brussels or the big energy companies) care little for the average voter in middle England (or Scotland, for that matter!) The worst thing that we could do now would be to retreat into an us vs. them mindset with the new administration.

Lord Deben chides politicians for failing to act on decarbonisation of heat

It is all well and good saying all new homes should be built with no carbon heating but until there is effective QAQC on house builders to achieve the highest standard of construction (particularly insulation) and there is effective controls on installation of no carbon heating it will make bugger all difference. By way of example: a friend had an Air Source Heat Pump fitted in the belief it would lower their heating bills. However they realised it was costing them twice as much to heat their home and actually wasn''t able to heat it fully in really cold spells. They subsequently switched off the ASHP and went back to the oil boiler and it actually uses LESS energy to heat their home. Old leaky houses will never be suitable for ASHP or GSHP as they can not hold the heat in well enough. Even newbuilds are so shockingly poorly built they aren''t efficient enough for ASHP/GSHP to work effectively and cost less in terms of both energy and money. Domestic (and Commercial) heating isn''t just about how to heat a building it is about making that building as energy efficient as possible. PassivHaus buildings can even be warmed purely by the people living in them with no extra heating required in many cases.

Report: annual 10% decarbonisation rate needed to meet UK's net-zero target

@Paul - that is very true and thank god for my chimney in summer. Whip out the "sheep" and get that draught going to draw the excessively warm air out the living room. While living in France we had external shutters on all windows. These massively reduced the incoming heat into our flat and still allowed us to open the patio doors to get a through breeze. In some cases the shutters could be lifted away from the wall at the base to allow access to window boxes or to allow a little more "indirect" light into a house. If you open a window on the ground floor and one on an upper floor you would get the same chimney effect I suppose. Danger is that in order to keep cool we all end up relying on Air Conditioning which is high energy demanding and adds to the problems in the atmosphere.

Report: annual 10% decarbonisation rate needed to meet UK's net-zero target

Keiron, of course, but you need all those other heat management measures. When a typical modern house is insulated to spec, they are warm in the winter but can be unbearably hot in summer. Opening a window doesn''t flush the hot air. I guess it needs to go up.

Report: annual 10% decarbonisation rate needed to meet UK's net-zero target

@Paul - I believe PassivHaus uses things like wider eaves to shade the house in the summer thereby reducing the solar heating effect of sun streaming in through the windows and the "heat recovery" used on the air circulation could probably work in reverse to help keep temperatures lower but I''m not sure on that. Of course you can still open windows to let excessive heat escape :-)

Onshore wind poised for first foray into Capacity Market

"...Their nameplate capacity totals 654MW..." Whitelee Windfarm with one of the best sites in the UK is 539 MW, with a cost 600 million. So 654 MW will cost about 728 million and with the same 27% capacity factor, over their [hoped for] 25 lifespan, will generate 39 million MWh of intermittent, dividend-paying, units of electricity. In 2025, building of the first BWRX-300 nuclear power plant [npp] will commence, for the breakers to be thrown in 2027. At a cost of 600 million, operating at a 90% capacity factor, with a 60 year design life, it will generate 132 million MWh of 24/7, dividend-paying, units of electricity. With a 2 year build programme, the cost-of-capital dilemma, that has plagued nucxlear power for decades, is obviated. 728 million - 39 million MWh Vs 600 million - 132 million MWh. What a head-scratcher for investors! Those pseudo-green, quick-buck, money-grubbing, pension fund managers will be drooling at the mouth to get their money out of renewables and into advanced npps. We''re not much more than a decade away from the prospect of investment in renewables withering on the vine. Watch out for your green-pensions.

How is the hydrogen produced? Is it by electrolysis of water or from methane gas, if the later then the delivery is in no way zero emission.

Is revoking Uber's London licence an environmentally sustainable choice?

Ride-hailing is not ride sharing and cannot be considered as environmentally sustainable. EV''s are zero tail pipe emissions, but still release particulates from tyre and brake wear and do not resolve congestion, plus there is still the carbon emission from making the cars to the electricity. The evidence points to ride hailing companies increasing the amount of car miles driven, the number of cars on the road and associated increase in congestion. Support for sustainable public transport needs to increase alongside active travel with an increase in good quality cycling infrastructure benefiting air quality, climate change and health.

Is revoking Uber's London licence an environmentally sustainable choice?

Can the author explain how hundreds of people driving hundreds of other people around in cars is environmentally sustainable? If ALL taxis/Ubers were 100% electric then perhaps but they aren''t. They sit at ranks waiting with their diesel engines idling all day or drive around hoping for a fare pumping diesel (and petrol) fumes into the city air. Surely in somewhere like London it is better to improve public transport (already miles ahead of most other places in UK) so no one needs to take a car/taxi/Uber/etc (unless they have a serious disability). Or promote e-bike use instead as the primary choice for personal transport in all our towns and cities.

Conservatives confirm plastic export ban and ?9bn energy improvements in manifesto

EasyJet says it could be flying electric planes within a decade

Keiron: As hydrogen is the lightest gas, any leak will disperse so fast in air that it can never make an explosive mixture, unlike petrol that can accumulate on the ground in puddles that become explosive. Electrolysis to make hydrogen is not efficient, but neither is a jet or internl combustion engine (around 32%). A hydrogen powered aircraft will be powered by electric motors that are much more efficient (around 80%), rather than burning hydrogen in a jet engine. You are absolutely right about where will the zero carbon electricity come from? but this is the same problem for electric vehicles. The point is, that the world faces a crisis in clean electricity generation that very few people recognise. Here in the UK in 2018 we released 2,234 TWh of energy from all sources, but only 351.2 TWh was to generate electricity and only 33% of that was from wind, solar, hydro, tidal etc. ie just 116 TWh of clean electricity. Assuming that the increase in demand for energy (up 30% by 2030) is balanced by the same reduction in losses by better insulation and better efficiency, then as all energy must be delivered as clean electricity by 2050, we have to increase clean electricity generation from 116 TWh to 2,234 TWh ie by 19 times. Unfortunately there''s only one other clean electricity generation and that''s nuclear. Hinkley Point C will generate 28 TWh a year running at maximum output all year 24/7, so we will need 67 more nuclear power stations like that, to all be running by 2050. The present Hinkley Point C will cost 20.3 billion if there are no cost over-runs, that comes to a total of 1.36 trillion. Yes we do have a problem about where will the zero carbon electricity come from?

Target meets 2020 goal to install 500 rooftop solar arrays ahead of schedule

Report: annual 10% decarbonisation rate needed to meet UK's net-zero target

Easiest way to reduce energy demand is to build houses properly to the highest energy efficiency standards. Right now even with the current building regulations the actual energy demand of the average house is 40 to 200% worse than regulations. This is due to zero Quality Assurance of house building. We have all heard of the 5pm Friday effect where insulation isn''t installed properly or the wrong materials have been used. Build all new houses to PassivHaus standard with proper QAQC oversight and the UK can cut energy demand massively. Then start improving the insulation and energy efficiency of the older housing stock to As High As Reasonably Practicable. Source Heat Pumps are NOT necessarily the solution as they are not effective in older homes. They do not heat the water hot enough to effectively work with "wet" central heating and radiators, they do not heat the water high enough to kill Legionella in hot water tanks and will never be effective with the older, leaky properties. They aren''t even effective in cheaply built, rubbish quality modern buildings due to the lack of oversight on building standards. It isn''t just about generating electricity from wind or solar or switching to electric vehicles but about reducing energy demand and wastage and changing our habits and lifestyles without impinging on quality of life.

EasyJet says it could be flying electric planes within a decade

@David - my problem with Hydrogen is many fold but the main problems are 1) it is extremely explosive and leaks from absolutely everything (pipes, tanks, pressure vessels) and 2) it takes twice as much energy (electricity) to create the Hydrogen than you get back from burning it. Then there is the problem that when you burn Hydrogen you get a very powerful Greenhouse Gas - Water Vapour - in the exhaust (this is also the case in fuel cells). Water Vapour is the most effective GHG due to the volume of it in the atmosphere so is it wise to replace one GHG with another? Finally, everyone says "we can produce Hydrogen from the spare electricity" but where is that spare capacity? Right now the UK demand is 41.6GW of which 47.2% is being supplied by Gas and Coal, 16.5% by Nuclear and 26% by Wind (the remainder being Biomass, Hydro and Interconnectors). If we lose the Gas and Coal what takes over? And if heating becomes more and more electric powered demand will rise, potentially drastically, so where will the spare capacity to crack Hydrogen be? Even if the Sci Fi dream of Fusion happens, which has been promised since I was a little boy (and I''m now nearly 50!)

Government-backed trial of biomethane trucks slashes emissions for Asda

Since both sources of methane are purified to the same standard, and are chemically identical, it would alarming if differences were found. With regard to mixing hydrogen and methane, it should be noted that volume for volume, hydrogen provides only one the energy of methane. Hmmm Richard Phillips

EasyJet to offset all flight emissions, pushes for electric aircraft vision

The concept of an electrically propelled commercial I regard as nothing less than fanciful. The aircraft to which the text refers is a very lightweight single person plane, seemingly a twin propeller driven. If it is battery powered, it is apposite to note that the energy in one litre of fossil fuel requires the equivalent battery weighing some 70 kilos It may be a hydrogen fuelled fuel cell. Commercial hydrogen powered commercial have been proposed some time ago, the engines being jet engines. This comes under the title Cryoplane. The hydrogen was to be carried as a liquid. Very difficult, and requiring a generator and liquefaction units at the air port. Hydrogen is difficult stuff from all angles!! Richard Phillips

Why energy productivity holds the key to net-zero business - The Climate Group Blog

While we all have to improve our energy productivity, this is the consuming end of energy, the other is the production of clean energy. As it is likely that our energy will be delivered by electricity to meet zero carbon emissions by 2050, our present annual electricity production which is around 365 TWh is only 1/3 clean from renewables ie 116 TWh when our annual national production of energy is 2,235 TWh, so assuming the energy savings are similar to the increase in energy demand over the next 30 years, we will have to increase zero carbon electricity production from 116 TWh to 2,235 TWh. If we have the space to triple our electricity generation by wind, sun, hydro, tide etc that still leaves 1,887 TWh to be generated by new zero carbon energy, and the only available technology that can do that, is nuclear power, probably requiring around 60 new nuclear power stations similar to Hinkley Point C. Are our politicians listening?

EasyJet says it could be flying electric planes within a decade

Batteries will limit the range of electric planes as already demonstrated with hydrogen powered drones that have twice the range of battery only. NASA is underwriting a project by Grainger College of Engineering in the US to develop a cryogenic hydrogen powered plane (CHEETA) using fuel cells to convert the hydrogen into electric power. Responding to Keiron''s valid comment: by the time this aircraft is commercially viable, the hydrogen will be produced by clean electricity, ultimately by clean nuclear fusion power from 2050 onwards.

ENA calls for mandatory hydrogen boilers as CBI outlines new sustainability vision

Hydrogen - sounds like the perfect solution but it is fraught with problems. It takes twice as much energy to crack it from water as you get back from the hydrogen. If this is electricity it can be more efficient to cut out the "middle man" and just use the electricity. It is highly explosive and leaks out of pipes, tanks and pressure vessels (I know from personal experience using it in a lab environment). But the biggest problem with Hydrogen is when you burn it you create Water Vapour which is by volume the largest Greenhouse Gas. So you swap one greenhouse gas for another - hardly environmentally sound. Time to forget Hydrogen and concentrate on massively increasing building energy efficiency towards PassivHaus standard so no one needs to burn anything to keep warm.

Greenwash or necessity: What role does carbon offsetting play in reaching net-zero?

I more than most know business want to do their best and in all they do, some of us created our own "sustainability solutions" as far back as 1985. We educated and certified some 1300 European engineers and technical staff in impact-based risk assessment for professional work in a highly dangerous environment. It was based on dynamic and abstract thinking initially, the highly critical knowledge of how to avoid lethal incidents and how to deliver every operation as planned. In 1987 "Sustainable and Sustainability" was coined by the UN IPCC Dr Brundtland Commission, an important political "goal for change" the whole world supported initially. It was understood as a "holistic Ikea flatpack solution" with a complicated user manual missing the main tool and some screws. This was a new opportunity to get rich and quick, selling a product you did not see or even fully understood and the Green Industry came down on the market as a Green "avalanche" and thousands were swept away. The "Sustainability Business" model became a way of "counting and reporting dead bodies" instead of "avoiding murders today and prevent it in the future" for the sake of our children. We were developing an idea for combined rainforest conservation, national aid and impact investment in 2004, to secure land rights to the indigenous people and begin replanting deforested areas with native species on a plan off agro-forestry. We developed the idea of various types of "offsets" even containing equities, we would sell to business seeking to change own production and operation or simply add to their business records. We would show real and measurable results for all GHG gasses, including all 17 SDG targets and deliver a lucrative result for investors and stakeholders without any "Greenwashing". The global sale of "Black Offsets" (my definition) became another easy money agreement between green politicians and the finance industry, greenwashing became BAU and no one asked for measurable SDG results from business, services, products or projects. The 1500 pages "Sustainability and Climate report" from 2005 gave Nobel Peace Prize to Al Gore and my friend in 2007, the 2015 Paris Agreement was later commented by hundreds of climate scientists we only have another 10 - 12 years to deliver sever changes and by 2030 especially because emission is rapidly increasing also in 2019, 2050 is no longer a positive option in my opinion. This is how I have experienced and understood the situation, 1 000 000/One Million species is extinct and even its called "Net-Zero Carbon" we are emitting 28% more and are heading for +3,4C.

Redesign, collaborate and collect: Inside Coca-Cola European Partner's plastics strategy

Roger It''s great that there is a precedent and I most definitely agree that they should have a better solution than just using recycled plastic for their bottles. I only mentioned consumption levels because the whole consumer model of encouraging people to consume more and more is proving to be not only morally wrong but commercially unsustainable. The sugar tax is only a token, we need to re-evaluate how we position this type of product.

Redesign, collaborate and collect: Inside Coca-Cola European Partner's plastics strategy

Russell I would disagree that the "current levels of consumption couldn''t cope". Remember this is a problem for Coca Cola to sort out and pay for, nobody else not local authorities not government. Compared to Germany they are enjoying and have done for many years a free ride. Local authorities have had to cope with and pay for any packaging that Coca Cola saw fit to use. With a DRS system almost all bottles come back. In Germany you will see people picking deposit bottles (ie ALL) bottles up. It is becoming common to see signs saying "please leave deposit bottles outside of the litter bin so that they can be taken by others". That helps so that people don''t have to rummage through the bins. It helps keep a lot of litter out of the wild. The likes of Coca Cola just do not want to pay to accept and handle their used bottles. It is as simple as that. They have huge operations in other countries like Germany where they are obliged to take back returned bottles so there is no lack of know how. They are just pretending to do a bit until they will eventually be forced to do it properly.

Redesign, collaborate and collect: Inside Coca-Cola European Partner's plastics strategy

Its good that Coca-Cola are looking at their use of plastic. However, even by moving to recycled plastic isn''t the long term answer. A return deposit on reusable glass bottles, like we used to do would be a far better alternative, but the current levels of consumption probably couldn''t cope with such a system. The long term and sustainable answer would be to re-evaluate the cost of promoting buy one get on free offers of large plastic containers of soft drinks against the benefits of consuming these products via glass and cans.

From carbon chancellors to CCS: What green election pledges have major parties made this week?

Yet another 800m on CCS following the 1.8Bn already spent on a technology that simply wont work. Lets see the life cycle analysis and mass energy balance - inevitably this will show that the parasitic power requirement is virtually 1:1 i.e you require the power output of a power station to sequestrate the C02 of the power station. To power such a plant using renewable power is a nonsense as nothing is gained and much lost .

Including the paint that protects the beloved wind turbines, the plastics that make solar panels, the coatings that insulate the wiring in the Electric Vehicles and the battery packs in same.

Strengthen climate policies now or risk catastrophe, warns energy agency

That CO2 has a heating effect on the global atmosphere is undisputed. But the air contains, on average, one molecule of CO2 for every fifty molecules of water vapour, the predominant greenhouse gas.

The IPCC use one factor which is unprovenly high, and other theories cannot agree with the real world, a basic scientific requirement of any theory. There is plenty of assertion that CO2 is heading us for disaster, climate emergency in fact; the latest panic bellow. But they emanate from either ignorance or vested interest. The science is not yet resolved. But nobody listens

John Lewis & Partners: Net-zero a commercial opportunity for business

Thank you for & regarding this article, as well as e.g. a talk I went to this week by a Professor from the University of Reading on Sustainable Futures: Whilst it''s heartening & significant to see the way that "low carbon" has been replaced by "net zero", it strikes me that: bearing in mind what this books saying FYI (& more vital than BXXXXX) The Water Will Come; Rising Seas, Sinking Cities and the Remaking of the Civilized World Jeff Goodell, Black Inc, 2018 https://www.greenhousethinktank.org/the-water-will-come.html in the increasingly harsh reality that we''re being confronted with, concerning the need for extremely urgent action by 2025, we have to recognize the need for for more stringency than even "net zero" i.e. to make any impact on meaningfully reducing the carbon in our atmosphere e.g. to actually & actively get SIGNIFICANTLY BELOW ZERO CARBON, not just zero to today''s already vastly too high levels - and thus have a chance of reducing the likely 6m-9m of sea level increases (never mind other related impacts) otherwise coming our way worldwide

Greenwash or necessity: What role does carbon offsetting play in reaching net-zero?

@Andy - actually we don''t want to take CO2 out of the atmosphere at all simply control the amount. If we remove it plants will die then about 3 weeks later so will we as the food runs out. CO2 is actually the gas of life and not a pollutant at all. the 400ppm currently in the atmosphere is less than 1/4 of what it was when the dinosaurs roamed the planet so really it isn''t that high.

Greenwash or necessity: What role does carbon offsetting play in reaching net-zero?

Two industries that would lead to carbon reduction, and need funding are Starlite, a coat of which would make temperature control of buildings neutral, and biochar, which is the only method we have for taking CO2 out of the atmosphere en masse at the moment.

Greenwash or necessity: What role does carbon offsetting play in reaching net-zero?

If "offsetting" is done properly, for instance I offset my heating oil by supporting the Woodland Trust and Project Seagrass, then it can form a valuable part of the arsenal. Particularly for individual offsetting such as mine (please note I have no choice over heating fuel as we are not on the gas main and ASHP or GSHP are not an option either). However there is too much fluff, fog, confusion and misuse of the system currently so it easy, too easy, for a company or organisation to claim they fully offset when in fact it is nothing like and it is an easy way to achieve a marketing goal. We all need to be more cynical and ethical when it comes to offsetting. Asking "have we done everything possible to reduce energy wastage and emissions?" before we offset. The problem is we could end up using more energy to offset than we could save thereby actually making the problem worse. it isn''t just about carbon dioxide as water vapour is far more effective a greenhouse gas and it is our voracious appetite for electricity and energy in general that is more the problem than the gas we all exhale with every breath.

Birmingham Airport sets net-zero carbon target for 2033

The collaborative push for net-zero emissions in the built environment

An invention from the ''70s was Starlite, which if coated on the walls and ceilings of the office and home, could cut heating and cooling bills to near-zero, automatic windows could control most of the temperature adjustment needs. See: https://www.starlitethermashield.com/ An alternative to Starlite is Fireputty, invented by Canadian Troy Hurtubise, who was looking for financial backing for lab time so that he could make a household paint out of it, before his untimely death. There is a competition that Starlite and Firepaste could be entered in with a prize of US $1 million for a method of cutting cooling bills for buildings, with the idea that global warming will mean that more buildings will have to have cooling. A passive cooling system like Starlite and Firepaste, if made into a paint, would cut both heating and cooling to near-zero, both in turns of fuel needed, and CO2 emissions, and as such will probably be unbeatable in the competition. If you look at this YouTube video https://www.youtube.com/watch?v=aqR4_UoBIzY you will find the the likely components are 90% corn starch and 10% baking soda mixed into a putty using PVA glue. There may have been other components as well, because it has been made into a spray paint, and paint. You will need to crack the formula in order to make use of passive temperature control of buildings. To enter the competition, just head to: https://globalcoolingprize.org/prize-details/faq/

EV batteries could be 'huge waste mountain of the future', researchers warn

Electrification of just 2% of the current global car fleet would represent a line of cars that could stretch around the circumference of the Earth some 140 million vehicles, report co-author Professor Andrew Abbott, of the University of Leicester, said. Normally stuff like this would be filed in Private Eye by "Phil Space" 2% of the worlds petrol cars would take up the same amount of space. The battery in the picture looks like it could be disassembled by a bloke with a couple of spanners in and hour or so - and there are you tube videos showing just that. The cells themselves seems to be layers of material with a simple structure which don''t look too difficult to disassemble. Compare that with a picture of a pile of a couple of tons of ore. Which would be the obvious one to get the minerals out of especially if the old battery is already in the part of the world that you want to make your next battery. What are the reasons that EV batteries may become a "huge waste mountain in the future"? common sense dictates that it won''t but have they uncovered a major problem. If so that would be news

Oil and gas giants must cut production by a third to meet climate targets

Lots of words in the article. Is it really so complex or a smokescreen? "in Germany and the Netherlands, the totals reach 98% and 86% respectively" not sure about the Netherlands but Germany has a compulsory DRS and has for ages. I can imagine the 2% that gets out into the wild is about as low as you can get due to human fallibility. Meanwhile in the UK 26% doesn''t get returned and that is not likely to change much regardless of the number of pilot projects, initiatives etc that get regularly trotted out. Isn''t it bleeding obvious that the DRS system that many grew up with is the way to go. It also delivers all the used plastic bottles to Coca Cola so that they can pay for the disposal and not local authorities.

Optimistic but lacking action: Green groups offer mixed reaction to Environment Bill

It is good that the Government is making new laws to protect the environment. It is very disappointing, however, that the new laws exempt some areas of industry concerning biodiversity. That is counter-productive and inexcusable and very short-sighted. We welcome any new legislation to protect our environment but we must not relax and keep pushing the government and industry and farmers and the public to do much more. End investment in all fossil fuels at home and abroad. Stop the insane road building visions of our governments and restore bigger fuel taxes and massively invest in clean public transport. Many other things too. I believe only the greens can save our countries from self-destruction.

IEA: Offshore windfarms 'can provide more electricity than the world needs'

Kieron, neatly put on the useful range of wind power. The use of a single technology, is different. With coal, gas, or nuclear power, the outage of one unit is individual, the power sources are not unified. But with wind or solar, its one out, possibly all out. For one week last July, a high pressure area dominated the UK, and wind power went down to a few hundred MW, from a possible 20,000MW. From 20 power stations on paper to about one, and less, for a week. And all the business people and politicians can talk about is the potency of wind. All the right energy, but not NECESSARILY at the right time! read the reports from official sources, its all TWh, no hint of absence of demand lead power. They just do not know, end of story until they do understand. Richard Phillips

IEA: Offshore windfarms 'can provide more electricity than the world needs'

Until the wind doesn''t blow. Remember that unless the wind is more than 4m/s (14km/hr or 9mph) the blades might be turning but the turbine is a net consumer of power. Then when it is more than 20m/s (70km/hr or 44mph) they have to feather and brake them to stop them blowing up. If we rely on a single source of power, whatever it is, we will find times when the lights go out. Instead of focusing on what this or that can do we have got to concentrate on a varied, balanced generation capability involving all forms of non combustion generation (with some minor CCS Gas generation as emergency backup). I''m talking hydro, fluvial, tidal stream, pumped storage, compressed storage, solar, wind, thermal source pumps (Air, Ground Water). In the Mediaeval waterwheels powered blast furnaces to smelt steel so why don''t we look back to look forward?

This might be helped if the world''s celebrity culture, especially the film and media world persuaded it''s ''gliterarty'' that it is socially acceptable for them to wear the same outfit to more than one awards ceremony or gala ball. That might then send a powerful message to the masses that wearing what you buy until it wears out is part of the solution to environmental pollution.

Morrisons launches first round of rapid EV chargers

Why on the perimeter? If we really want to encourage a switch to EV then surely priority should be given to these and charge points should be located in the main areas of the car park, under a shelter, right next to the trolley point. With ANPR it''s easy enough to monitor and the trolley herders can keep an eye on the spaces and put a polite message on the windscreen of non EV cars to remind them not to park in the wrong space. @Colin - who are you getting your lecky from at 6p/kwhr? I pay 13.2p/kwhr so twice what you seem to get. Even so I agree 30p/kwhr is excessive given the SVR from the Big 6 is around 15p/kwhr

Morrisons launches first round of rapid EV chargers

Wow, 12p per mile for an electric vehicle compared to compared to 14p per mile diesel and 15p per mile petrol. Not much saving given The much higher price of the electric vehicle. domestic price around 6p per kilowatt hour compared to this rate of 30p-how do they justify that?

Government consults on green license plates for electric vehicles

A green number plate won''t make any difference to me and my choices. Price, range and design are much much more important. I want a decent mid sized car (similar to my C''eed), that can do 240 miles on 70% of charge (3hrs motorway driving from 80% to 10%) and doesn''t cost 30 grand. As a cyclist who often has to fight for space in bus lanes with taxis, motorcycles, disabled drivers and let''s not forget 20 tonne buses I might as well give up and ride on the pavement if green licence plated EV''s can use bus lanes too. I mean what would be any different to any other lane on the road? Forget gimmicks and focus on getting people out of cars as much as practical. Make public transport so financially attractive that it isn''t worth taking a car (ICE or EV) into town or even owning one if you live in a major conurbation. Hell even make bus travel free for all (not just the over 60s) if that gets people to use public transport. To give an example it costs my wife and I 7.50 return to go into town by bus. At 45p a mile (HMRC rate) it costs 3.60 by car. That gives us 3.90 for parking which is nearly 4hrs. So for a night out we drive, it''s cheaper and a hell of a lot more convenient as we aren''t limited by bus times (last bus home is early). If EV''s get even cheaper parking there''s even less reason to take public transport meaning we still have a congestion problem. And finally, where''s all the power coming from to power all these EVs that everyone is going to have? Can the network cope? I doubt it as the lights flicker in my house on a regular basis meaning if I plugged in an EV to charge I''d black out the neighbourhood. Mr F Popular!!

Renewable energy to expand by 50% in next five years - report

But "appetite of energy-hungry businesses and factories" will expect their appetite to be satisfied by the availability of electricity when and as it is needed. Both solar and wind power are to noted for generating electricity on their own terms, not on demand. None of the economists or businessmen speaking on this subject ever address this pivotal point, or the geographical diversity and distances from points or generation to consumption.

'Risking a carbon budget blowout': UK Government gives go-ahead to Drax gas plant

Hold the front page: The Guardian targets net-zero by 2030

Hello Tim. Yes, I am aware of the solution to the "problem" of radioactive waste, it was with us well over 40 years ago, it lies in vitrification, sealing into stainless vessels, and then into geological disposal. The scientists and engineers involved understand it well, the problem lies with political go ahead. The political body responsible CoRWM, have kicked it down the road five times over decades, it scares them stiff, simple non-comprehension. That 16% nuclear was at one time 26%, but HMG simply will not invest, has not done so for over 30 years, so our old reactors go valiantly on for well over their design life. With no replacement when they close down. Wind turbines deteriorate after about 12 years or so, design life 25 years. I admire your totally unfounded optimism over a "technical" to intermittency, what will be doing the generation? Have you looked at the cost of storage of any sort, it becomes comparable with our GDP. And don''t forget the problem of over generation from wind turbines in very high winds. Absolutely no control over the weather. High proportions of renewables, over about 30% for wind will pose serious problems of instability. In the winter of 62/63 the whole of the UK was snow covered and temperatures never rose above 0oC for over five weeks. Coal to the power stations was heavily loaded with ice-problems. Our then new nuclear stations prevented blackouts, working at 98.5% of their design capacity for all that time. The lights and heating kept on. I was living in a prefab, with a wife and baby, on top of the Berkshire Downs at the time, well recollected. There is absolutely no prospect of renewables performing in such a fashion. I must not go on so!!!!!! Richard Phillips

Aside from which 70 yrs of investment in nuclear technology has given us a source of power accounting for 16% of output (gov''t figures 1st Qtr 2019) Vs 35.8% for renewables. Hardly the basis for hope, given the financial price to consumers (latest 40/Mw hr vs 80-odd/Me Hr nuclear) And that''s without going into the cost of Three Mile Island, Chernobyl, Fukushima etc. There will be technical solutions found to intermittency and other supply issues for renewables. I''m not aware of a successful solution for the mountain of radioactive waste that nuclear power produces. Are you? Or fall out from melt down of an atomic pile?

Interesting article. Perhaps Pret could do more about communicating some of these issues; even if it''s only the 10% who recognise that there are trade offs who read them, that''s still a sizeable number of customers. More detail on the relative lifecycle emissions calculations for plastic, aluminium and glass would be welcome, too.

'We're up for it': Sky exploring its role in net-zero future

A 10 kilometre deep lined and capped water well can convert all power stations to clean energy, a cut of 30% in CO2 emissions. A 20% cut would come from electrification of all vehicles. 41% would come from coating all buildings in Starlite. Aircraft and Ships could halve emissions by using fuel mixed with water using an ultrasonic dibber. Aircraft account for 6% of CO2, while shipping accounts for 4.5%, so another 5.25% can be saved. The total savings would then be 96.25%. Improving soil using biochar would then cut CO2 in the atmosphere by locking it in the ground. Cement based on magnesium silicates, not only requires much less heating, it also absorbs large amounts of CO2 as it hardens, making it carbon negative. It can all be paid for by eliminating mental illness using the Kadir-Buxton Method. Biochar is an ancient invention being found by archaeologists that locks atmospheric CO2 in the soil for thousands of years, a by-product of it''s soil improving function.

Report: 'Sustainable' seafood in UK supermarkets 'wiping out wild fish stocks'

A Practical Solution To Fish Stock Depletion Fish in the wild are being over exploited, and whole fish species face extinction. But there is an easy way of preventing these extinctions. An international law should be passed which ensures that the gonads of all fish caught are liquidized and put into water containers, the fish are usually gutted anyway so this would not be a great hardship for the fishermen. Once liquidized, artificial fertilization takes place, and after twenty four hours the fertilized fish eggs can be released into the sea. It does not matter where the eggs are put back because the fry of each species find their way back to the environment they originally come from. In this way, the sea can be repopulated, and fishing can even become sustainable. The Japanese were the first country to fish in this way, and had their Navy protect the massive shoal until the fish matured. I have only heard of it being done the once, though.

EPCs: The seldom-used tool that can unlock greater efficiency - The Mitie Blog

This approach is by far the simplest and best aproach to moving into a carbon neutral world as it allows all companies and domestic energy users to start working towards being carbon neutral without extra cost. The only issue i have found With domestic users is that they can''t be bothered to change somthing if it is working perfectly well For instance why change a lightbulb that cost 50p for an led bulb that costs 3 what they are unable to see is that the 50p bulb will use 90% more energy than the LED so will cost more over the life of the bulb because most are unable to work out the cost saving and therefore have to trust what someone else tells them but are reluctent to do because it sounds too good to be true.

Renewable generation overtakes fossil fuels in UK electricity for first time

Roger, I have little sympathy with public subsidy for platform removal; was gas and oil not a private industry, highly profitable? Why did they not pay, they put them up. With regard to gas imports for power, fracking for our own gas has been tossed aside at the behest of an ignorant fringe, why? The matter of redundancy is more complex than your description. Certainly power stations were running at a low level, but gas stations still do, in order to balance wind generation and demand. This is uneconomic, so they have to be subsidised. There are worries in this area, now termed power inertia. But as wind power grows, and reliable fossil generation falls, it is falling also. For a serious outage, all the deft rapid communication on Earth will not replace actual generation. Forget batteries for industrial quantities, the cost would be a serious portion of GDP. Yes, I would opt for spinning reserve, inertia, wind and solar have none...Above about 30% wind power this is regarded as serious. Serious wind outages, ie generation of a nominal 20GW down to a few hundred MW, can last for days on end, and did so last July. But in mid-winter that is not good I agree entirely with your comment concerning the place of engineers. The original Grid was built on the specifications of two electrical engineers, Mertz and Kennedy their work was almost verbatim in the form of the Electricity (Supply) Act 1926. Completed in 1935, it enabled the UK to have a powerful industrial base in WWII. Certainly engineers will build and run our Grid, after the accountants have agreed. We only have such a poor generator as wind because it has been very profitable for the suppliers I am convinced that our electricity supply would be an optimum or thereabouts with some 80% nuclear, balance UK fracked gas. Renewables should not feature on account of their unreliability. But this takes time, simply because a certain Prime Minister dumped all our nuclear industry, about 30 years ago! Richard Phillips

Government unveils new net-zero support for buildings and 'every single mode of transport'

The linked paper mentions nothing about ''minimum energy efficiency standard of EPC band B by 2030'' - can you supply the source please.

Government unveils new net-zero support for buildings and 'every single mode of transport'

First off they should immediately change the planning laws and building regulations so ALL new build properties (domestic and commercial) have to be constructed to A+ energy efficiency including use of non combustion based heating systems. That should be backdated to the date of the original announcement. There is a new development of "social" housing about to be constructed here in Fort William that talk is will be fitted with gas central heating - in a town with no mains gas. Social housing should be constructed to minimise the cost of living to those living in them and new builds should not be allowed to fit combustion based heating now. As a cyclist, in Fort William (the wettest town in Europe) to encourage me to cycle there needs to be secure, covered cycle racks and possibly even changing facilites dotted around town. Morrison''s have a "second thought" cycle area which is pathetic and located away from the main entrance. There''s very little cycle storage in town and forget trying to dry off and get changed. Finally, what options do the government have to decarbonise my home heating? As we have no mains gas we have to use oil. Some homes still have to use coal fires and a back boiler! ASHPs are no good for our needs, ask any number of council tenants who have had them fitted and hate them as the house is damp and it costs 4x as much to run. I offset through Woodland Trust and my oil company also offset but to replace my central heating could cost me 10''s of thousands. Until I see some sensible strategies and real action I''ll take all of this with a massive pinch of salt as really it is just normal political hot air.

Renewable generation overtakes fossil fuels in UK electricity for first time

Richard Phillips There are enough reminders from the press to ensure that we never forget subsidies for wind generation but the fossil fuel subsidies such as the tax payer funded decommissioning of North Sea platforms dont seem to find the space. The North sea was a great boon to the nations balance of payments and if subsidies were necessary to get the benefits then it was money well spent. As you are probably aware the UK imports increasing amounts of gas and reducing our reliance on foreign imports must be a good thing. When the national grid was set up there were huge amounts of redundancy because the technology of the day could not cope with sudden change. Today''s grid is much more efficient with high speed communication and the ability to supply large amounts of power within seconds. Would you like to go back to the good old days of spinning reserve where coal stations were all powered up but not producing anything. As for itemising all the subsidies on a consumers bill. Is there ever an example of an invoice that lists the tax paid, directors bonuses, labour transport etc etc. Because they are not listed they must be "secret". The Amazon invoice would be bigger than the parcel. I agree that "the government simply do not understand the science" so it is lucky that engineers are running the grid and I am sure that the people who have kept it running since the 30''s without interruption including the war, would have noticed the danger of grid instability and taken measures against it. Go to http://www.gridwatch.templar.co.uk/ and see in real time how the grid seamlessly balances wind gas coal nuclear and foreign imports.

Renewable generation overtakes fossil fuels in UK electricity for first time

In the apparent bargain price of wind generation, have we somehow forgotten the subsidies still paid for offshore generation? And we must not forget the very large additional cost of this highly and rapidly variable source on the additional costs from National Grid. None of these are itemised on the consumers bill, indeed a lot of it is secret. The danger of grid instability due to the high variability of wind power seems to be lost on the upper echelons of Government, who simply do not understand the science, so ignore it; and upon so many reporters in this area Richard Phillips

Renewable generation overtakes fossil fuels in UK electricity for first time

A good start, however let s see the figures for quarter one 2020 when the electricity demand is at its highest in winter and offshore wind or solar may not be at their optimum generation level . Remember government also wishes to transfer heat to an electric platform and as such that requires an additional twice the capacity of the current electricity generation capability. In all cases you need to have The maximum demand point Capacity available otherwise people Or industry will have to go without. This is just reality.

Coca-Cola unveils drinks bottle made from recycled ocean plastics

Just enforce deposits on their bottles as they do elsewhere in Europe and then Coca Cola can recycle them the bottles themselves. At the moment they rely on local authorities to dispose of them, litter the countryside etc. I am getting tired of the stream of "initiatives" to make bottles more recyclable. Slap a deposit on the bottles, watch them disappear from the seas and countryside and deliver them all to Coca Cola. Then they really will become recyclable and Coca Cola will disappear from the news. They do it in Germany and nobody has to care.

'Risking a carbon budget blowout': UK Government gives go-ahead to Drax gas plant

Whilst being absolutely no fan of this project, would it have been worth mentioning two things: 1) I understand that these turbines will be replacing ones currently powered by coal burning. They will therefore significantly reduce CO2 emissions compared to the current fuel. 2) Drax is committed to CCUS research for its wood pellet burning units. I presume therefore that they have a serious intention to carry that work through to this project. If that is done and if the government stops prevaricating and builds a network to allow seabed injection, then the project does effectively become carbon neutral. Was this the reasoning for Leadsom authorising the build?

Look it isn''t all about fuel when it comes to oil and gas. Where do you think the plastic materials used to make your smart phone, laptop, solar panels and wind turbines come from? Yes PETROCHEMICALS all produced from oil and gas as the raw feedstock. Now look at your wardrobe, how many items are made from polyester, nylon, acrylic? How many have Lycra(tm) in them? All synthetic fabrics made from oil. Whilst I agree that we can not afford to simply burn the stuff we as a society will need men and women like myself to go out into the worst Mother Nature can throw at us (as I type the wind is up to 35kts out here and increasing) to find and produce the raw material for millions and millions of everyday products each and everyone of us wants and needs. Like the insulation around the electric cables in your house, the casings around the batteries in your EVs, the paint that protects the wind turbines from the seawater. Only if you want to go back to burning whale oil in lanterns and wearing hessian undergarments can you honestly say you don''t want to invest in oil and gas.

Conservatives hint at plans for earlier petrol and diesel car sale ban

Some confusion here re vehicles! You give a link to the CCC''s recommendations for all "conventionally powered petrol and diesel vehicles" sales to stop in 2035. The CCC report says " the deadline to make electric vehicles the only mode of transport should be brought forward to 2035 or earlier, the CCC says. Huge difference. Current HMG recommendations are for all "conventional" petrol and diesel vehicles to be banned from 2040. This is a way of allowing local authorities to insist that hybrids run on electric power in towns and cities to reduce air pollution. Banning all petrol and diesel vehicles is completely different and begs the question of how you generate the electricity to charge them. Some clarity on this would be welcomed!

Coal drops to record low generation share in UK

A Buxton Geothermal Turbine Generator is a lined and capped well, filled with water, which is ten kilometres deep. Because the ground heats up at a constant rate the deeper one digs, the cap of the well is at three times boiling point, the precise temperature at which power stations generate electricity with their turbine generators. Any power station can easily be converted to Buxton Geothermal Turbine Generators. The power they can generate is only limited by how wide the well is dug, and energy generation greater than nuclear power stations is easily possible. It should be noted that due to temperature variations in different localities, the well would have to be dug until the temperature at the bottom reached three times boiling point, which is an average of ten kilometres. As far as the cost of such a project is concerned, the recent Aachen bore hole was dug to a depth of 2.5 kilometres in three months, so we can assume that it would take just a year to get down to a depth where the rocks are at the temperature of three times boiling point. Figures available on the internet say that a bore hole of 5.54 kilometres costs 4.7 million, which equates to 8.5 million for a ten kilometre bore hole. This is thus a very cheap way of cleaning up the pollution caused by present power stations. There are approximately 107 main power stations in the UK producing 47 million tonnes of carbon (2004 figures) or 30% of the total UK production of carbon, and this would take 909.5 million to convert to BGTGs. A drop of 30% in carbon production would go a long way towards the Government''s present target of 60% of 1990 emissions by 2050. We must also compare the cost of converting all power stations to BGTGs with the conservative estimate of 2 billion to build just one nuclear power station.
