Keele University launches Europe's first at-scale smart energy living laboratory

Spot on Keiron. This project will help enormously. In the early 80''s I was doing an electronics course and one exercise was to design a central heating controller using a microprocessor. I thought at the time this is great and that real engineers would be working on real world products and they would be appearing very shortly. It was probably 30 years before this started to happen and we are still miles away.

Landmark sector deal to make UK 'world leader' in low-carbon mobility

What is it about this country that nothing can happen unless "world leadership" is in the headline. Isn''t "successful" enough. World leaders emerge after a period of achievement and not by announcement.

Keele University launches Europe's first at-scale smart energy living laboratory

Smart Energy is also about using energy smarter and not just generation and storage. Currently most houses have a dumb heating control system with minimal programmability and temperature control. Most still use a dumb master thermostat stuck in the hallway to control the entire heating system, meaning quite often the thermostat is set too high in order to maintain heat to the rest of the house which results in the heating running more than needed. Proper programmable, digital, smart heating controllers that take information from every room and radiator to determine the heating requirement of the home and that can accurately control the HW system (even putting in an anti-legionnella cycle once a week if there''s a tank) will dramatically reduce our energy demand in both home and business.

25-year Environment Plan: Seven key talking points for sustainability professionals

I can t honestly see anything in this. No ideas, no commitment nothing. 25 years really is kicking it a long way down the road. I note that the Germans got their "duales sysytem" for packaging waste up in 3 years a mere 25 years ago

Scotland pledges to ban plastic cotton buds

What would be even better would be teaching people not to throw things like this down the toilet in the first place. "If it ain''t been through your pipes don''t put it down the toilet pipes"

Tesco supports deposit return scheme for plastic packaging

Norway has had bottle deposit return system in ALL supermarkets for over 20 years. Easier to centrally mandate it in a smaller country no doubt, but plenty of lessons available to help the U.K. Catch up.

Amazon completes lucrative solar roof installation

Well done to Amazon for using what would have normally been "dead" space for this solar array and not using a farmer''s field. More big companies need to take this approach to solar generation and use the space above our heads more.

War on plastic waste to play central role in UK's 25-year Environment Plan

The only way to deal with waste plastic is to recycle drink containers, easily separated from other packaging, and burn the rest to generate electricity. Enough is known on the construction of suitable furnaces for this purpose. It must be a project entirely in the hands of HMG, not handed out to private undertakings who have no co-operative approach.

London to gain additional 1,000 EV charge points

" (GLA) and Transport for London (TfL) have allocated 4.5m to 25 London boroughs to roll-out 1,500 new charging points." That is 3,000 per point, all paid for by ratepayers, how long is the pay back time?? All for the benefit if those able to buy relatively expensive electric cars!! Richard Phillips

War on plastic waste to play central role in UK's 25-year Environment Plan

Plastic is easy to see - PM2.5s aren''t. Theresa Mays speech highlights the complete lack of understanding that is causing the premature deaths of 60 000 Brits annually. It''s no surprise that the NHS is under unprecedented strain. Where is the joined up thinking - there is no prevention strategy. Gov think everything is solved by tax . Air pollution affects us all - if you can''t breathe nothing else matters - just because we can''t see PM2.5 doesn''t mean this Government can ignore it. So why is she ignoring this report?: https://www.rcplondon.ac.uk/projects/outputs/every-breath-we-take-lifelong-impact-air-pollution

Central Heating - is the future smart? - Sustainabilty Musings from the Cesspool of Life

Argh!!! Regulations and Red Tape!! Apparently it is illegal to fit a heating system without a room thermostat and a tank thermostat. The tank I can understand (if fitted) as there''s no point in heating the water hotter than it needs to be which is also dangerous. 60C is as hot as it needs to kill Legionella so no point going higher. A programmable tank thermostat would be good so you can run a legionella cycle once a week but only heat to 55C the other 6. But the room thermostat? In the hall? Controlling the entire CH circuit? Where is the thinking behind that? Stuck in the 19th century obviously. If the "master" thermostat says "I''m at temperature thank you, please shut down" what happens to the rest of the house if it isn''t at temperature? Do the TRVs become obsolete? If so then all that happens is we try to heat our halls to a higher temperature just to ensure the living room is warm which is a total waste of energy. So much for "Zoned" heating if the whole system is controlled by 1 dumb thermostat in a cold hall. Surely it is not beyond the realms of 21st century electronics to come up with a control system that monitors and adjusts demand on the CH circuit according to inputs from all the TRVs, remote room thermostats and even external temperature sensors so that each radiator (or underfloor heating unit) get the right amount of hot water to achieve the desired temperature, using IFTTT logic. Precise heating control means only the energy needed is used and if the system is all at temp then it goes into standby, the boiler is off, the pump isn''t running and the meters stop ticking. A Raspberry Pi, some wires, perhaps some micro sensor and a few algal rhythms might be all it needs. Trouble is I''m used to dealing with silicon in a different form. Perhaps I am missing something but I have yet to find a system that does this. Any options others have found gratefully received, especially if it does away with the bloody hall thermostat :-)

UK's largest battery storage portfolio unveiled

@William Walbank - I agree with you about the confusion over units. It''s all well and good talking about power when what is more important is supply. I have a 135amp-hr 12v battery on my boat. I can draw 1 amp from this for 67hrs without damaging the cells or 67amps for 1hr. If I tried to dray 135amps out of it I could do it for 30mins or totally destroy the cells. Battery storage on a grid scale has got to be able to supply power for a prolonged period or it will be next to useless. It is time to talk Watt Hours not "homes"

UK's largest battery storage portfolio unveiled

Another useless article - What is capacity of the battery backup banks in kWh or MWh ? It gives power output - but for how long? The slack editorial practice of quoting output power rating only ( MW/kW) when often the data was intended to be energy capacity (MWh/kWh) is all too common in Journals that should know better. In so many cases the author''s intent is not clear and evaluating the system performance potential is confusing or impossible.

Theresa May hints at plastic bottle charge ahead of key environmental speech

Dear Edie.net and Readers, Becoming a world leader in resource efficiency really does not matter at all. Due to its natural conditions and factors, it is a non-competitive win => everybody wins, the earlier they start the longer term they have to enjoy the fruits. Sustainability either we mention environmental, social, economical or legal responsibilities, if we emphasize the case of the Innocent Drinks, we have to acknowledge that philanthropy comes first. And second and third... Raising awareness and creating consciousness is the first and evermost important task of any governments. The UK PM might also refer to the UN SDGs, or just commit herself to the wellbeing of its home country. Best, Fatima

Theresa May hints at plastic bottle charge ahead of key environmental speech

"This is completely different to plastic bags, where you could opt out of buying one and bring your own bag." - you can opt to buy and bring your own reusable water bottle increasingly there are cafes around which will refill you for free, see Refill.org.uk "What alternative will we have to all the many things sold just in plastic bottles? I buy olive oil in glass bottles and the price hike on plastic is more than 5 pence." Olive oil isn''t a single use plastic so it hopefully won''t apply, which is apt as a fizzy drink bottle is so much more likely to be drunk out and about and then improperly disposed of than something like cosmetic bottle

Theresa May hints at plastic bottle charge ahead of key environmental speech

Theresa May hints at plastic bottle charge ahead of key environmental speech

This is completely different to plastic bags, where you could opt out of buying one and bring your own bag. All this is likely to do is encourage people to buy bigger bottles and reuse the smaller ones they already have. There is a reason they are called single use plastic bottles and reusing them can lead to health problems caused by toxins leaching from old plastic bottles.

Work underway for England's 'largest' district ground source system

How about doing this with Water Source Heat Pumps utilising the heat energy flowing down our rivers? Or around our coasts where we have the benefit of "tropical" water thanks to the Gulf Stream. One drawback of large scale Ground Source Heat Pumps is if you extract too much heat from the ground you risk freezing the soil. Still it is good to see someone is thinking about how we heat our homes and how we can do this on a large scale without the need to burn things.

Diesels suffer as UK low-carbon car sales soar in 2017

Fitting a simple device that creates hydrogen and oxygen from water and injects minute amounts into the diesel engine can reduce CO2 emissions by 80% and NO emissions by up to 50%. This can be retrofitted for around 500. Surely there is a no brainer to incentivise Diesel owners to fit such a device and mandate all new diesels to have it rather than introducing yet more complex charging systems and penalties!!!

UK government spells out plan to shut down coal plants

Andy - thanks for the link, I''ll read it when I get a chance but hopefully soon. Agree the heating demand will reduce with time as we drive to improve energy efficiency in newer homes but that still leaves a huge quantity of older, less efficient homes needing non (or low) carbon heating sources. We have to remember that the majority of homes in Britain are heated with gas central heating or, like me, oil (as we aren''t on the gas main). The simplest way to replace the gas/oil boiler is with an electric one but it still takes the same amount of energy (kilojoules) to heat a litre of water regardless of the source. I don''t know about you but my heating energy demand is a hell of a lot higher than my electric demand (CH and HW). Agree with you though that EVs are going to present a challenge to the supply especially if everyone is plugging them in around the same time every evening to have them full for the morning. That is going to be one heck of a spike in demand!! And not convinced about the EV storage argument either.

UK government spells out plan to shut down coal plants

Kerion - Link below to work done for future energy scenarios (FES). I get the impression as renewable / storage capacity grows the CCGT will aim to replace coal for peak demand spikes. Low carbon heating systems will generally be installed in new homes, which will have a lower heat demand due to improvements in building regs. A larger problem IMO is the grid capacity to deal with electric vehicles. Hopefully SMART gird technology can come online to deal with that. http://fes.nationalgrid.com/media/1245/fes-in-5-for-web.pdf

UK government spells out plan to shut down coal plants

Andy - I follow Gridwatch quite regularly and it is my main source of data on power generation. On 19th Sept Coal out generated Wind by 5.7GW to 0.62GW which is as close to 10 to 1 as make little difference. On 10th Dec it was 4 to 1 in favour of coal and 5th Nov it was 8 to 1. Now I agree these are snapshots rather than the monthly chart but it still shows how much we still need the old coal stations. Without a coherent plan to replace the GW available from coal we run the risk of the lights going out. Especially if we head to low carbon or no carbon central heating systems which will dramatically increase the demand for electricity. Don''t get me wrong I am not pro-coal I just want to ensure we have a reliable, sustainable but above all suitable power generation system that is fit for the future and not the result of some political knee jerking.

UK's largest battery storage portfolio unveiled

This is excellent news and shows that we are, at last, on the first steps to provide a comprehensive electricity storage infrastructure in this country. Research and development here will provide huge dividends for the power requirements of this nation in the years ahead and enable us to move towards a future powered by renewables, without the pollution of fossil fuels and the dangers of the ridiculous fission element in both generation and waste disposal.

UK government spells out plan to shut down coal plants

I agree with the need for forthcoming plans for new generation capacity. However, where are you getting the 10x coal to wind figures from? Have a look at the "Monthly Nuclear/Coal/CCGT/Wind (GW) Chart" on Gridwatch. I''d say coal / wind are fairly equal, with wind edging it a bit. http://www.gridwatch.templar.co.uk/

Theresa May hints at plastic bottle charge ahead of key environmental speech

How would it work? With bags we had an alternative - bring our own. What alternative will we have to all the many things sold just in plastic bottles? I buy olive oil in glass bottles and the price hike on plastic is more than 5 pence.

UK government spells out plan to shut down coal plants

And where is the plan to replace the generation capacity lost from the shut down of all the coal plants? Several times in the last couple of months coal has been providing as much as 10x more electricity than wind turbines due to the cold, calm conditions over the country. Do we have a contingency plan to deal with this kind of weather in the future without just burning more gas?

UK's largest battery storage portfolio unveiled

Two questions - how long can this battery provide "grid" power for and how long does it take to recharge them once they are empty (ie 20% Depth of Discharge to 100%)?

Latte levy: MPs call for systems overhaul to recycle all disposable coffee cups

We now have simplycups.co.uk supporting instore recycling, and the A e Sonneco paper juice carton recycling scheme is now open for paper cups, it has never been easier to recycle a paper cup, can we now get on a solve the real problem , a cordinated recycling scheme across the country.

WEEE: Tackling the next big business challenge

Some positive news here. the attitude of Samsung to ''local'' repairs and upgrades is heartening too. In my experience the biggest issue is the lack of easy recycling. I have to drive 14 miles (28 return) to drop off anything electrical. I suspect from conversations with local people that they simply dump it in their grey waste, where it either gets incinerated or goes to landfill. That means CFLs and batteries etc are all contributing to future recovery/pollution problems, as well as requiring raw material replacements.

H&M launches sportswear range made from recycled polyester

Does this mean they will continue to pollute our world and its oceans for another 10 years? Micro plastic pollution from polyester has become a major concern and this sort of time-frame sounds dismissive of that problem. Is polyester sustainable? (polymer chemists please advise) Does ''climate positive'' include action to recover the micro plastics flushed into our environment and entering our food chain?

Latte levy: MPs call for systems overhaul to recycle all disposable coffee cups

I worry we are putting all this effort into paper cups, when the real issue is a cordinated recycling scheme across the country, it feels akin to building a car and we are worrying about the door handles, but we have not got a engine or wheels on it yet.

Starbucks trials 5p charge on disposable cups

Interesting attempt at nudge behaviour. As the article points out, Starbucks already offers a (bigger) discount to customers who bring their own cups, so unless I''m missing something, all they are really doing is quoting the lower price and adding a premium for providing the cup. As I understand it, behavioural theory suggests that this may be better at encouraging change (people don''t want to pay extra) than by offering a discount (people have already committed to the purchase, so this discount is only a "nice to have"). Of course, if the odd 5p really matters, you probably wouldn''t go to Starbucks in the first place, as it''s usually among the most expensive places to get a coffee on the High Street. It would be interesting to try this with Pret''s 99p filter coffees. which may attract a more price sensitive clientele.

Innovate UK backs project to boost EV range to 400 miles

246 million may well be going in the wrong direction, Would suggest that a independent group should assess a concept for a Hydrogen Rotary Engine-generator to power EVs. Not only does this have potential to bring about Affordable Zero Emissions EVs. Having been joined by ACE Hydrogen production system/unit(USA) this Power Pack overcomes the Hydrogen Impasse, No need for charge points or H2 Filling stations. Does it not make economic sense to fully explore Hydrogen Combustion and Hydrogen Production On Board the EV. Hydrogen produced on board as a On Demand system, no super high pressures storage tanks. The Faraday Battery Challenge may be overtaken. Compare the economics 1.5 million to develop Hydrogen Combustion and H2 Fuel supply to 246 million over 4 years. There will not be any massive cost to scale up existing Global Engine plants can soon gear up to 40,000,000 per year.

Carbon footprint of Scottish homes slashed by 25%

Hanrahan continued: A new Climate Change Bill this year is an opportunity to double down on our commitments to make our homes more energy efficient, __________ Heat pump electric heaters are more efficient, and can be supercharged if an air source heat pump uses gas boiler flues as the heat source. Gas central heating systems can be made more efficient by * adding radiators or replacing small radiators with large radiators or single radiators with double radiators where a central heating system doesn''t have enough radiator capacity to work efficiently and the return water is still hot. * upgrading gas boilers to condensing boilers __________ Hanrahan continued: ... to increase the use of renewables to heat homes, and put Scotland on the path to a zero-carbon future. __________ Electricity We need new (renewable energy) back-up power capacity for when the wind is not blowing adequately, from new-build biomass burning power stations, considering that is now too late to convert Longannet to biomass burning as I advised. Consumers are not going to switch to heating homes using electricity away from gas unless electricity becomes cheaper than gas. Gas We need (renewable energy) hydrogen (from electrolysis using surplus wind power) injected into the gas supply network. This requires more wind turbine capacity to generate more surpluses more often so we can generate all the hydrogen we need. However I don''t see how a "Climate Change Bill" is going to do any of that. It''s not the law that is the problem, it is the budget that is the problem, the lack of investment, in housing, in electricity supply. The Scottish government needs to invest more money and I explained how it can do that in my contribution to the energy consultation. "So the Scottish government should really be confronting the limitations on its own borrowing powers which it had imposed on itself by signing the Fiscal Framework Agreement of February 2016. Setting a political target to summon up the political wisdom and courage to rip up that bad agreement and press for a better fiscal framework which would allow the Scottish government to borrow to invest in a green bank would be the better target. ... It s a government responsibility to invest using its own borrowing powers to borrow from its own central bank, interest free, with no repayments expected and the borrowing simply added to the national debt. The Scottish government must really focus on securing for itself those borrowing powers up to I recommend a minimum limit of at least 8% of GDP allowing for up to another 10 billion a year of Scottish government borrowing for investment. My concern is that the notion of a Scottish Renewable Energy Bond is a Scottish government without borrowing powers that it has failed to secure via a fiscal framework agreement, trying to dodge its responsibility to borrow to invest in the renewable energy sector, if necessary by repudiating the existing fiscal framework agreement and making a political issue of the UK s refusal to offer the Scottish government a new and better fiscal framework agreement with substantially enhanced borrowing powers as I suggest. Really there is no good excuse for a bad fiscal framework agreement that doesn t allow for the Scottish government to borrow to invest as necessary. Now such matters are not for the Energy minister alone but the fiscal framework is a matter ultimately for the First and Deputy First Ministers and the Finance and Economy Secretaries. Really it is not acceptable for any of those ministers to agree with a fiscal framework which does not allow for the necessary and sufficient borrowing powers."

New ?40m partnership to help UK communities take over solar farms

So, when the government reduces the free money for businesses, these businesses monetize their investment to citizens? Then groups of citizens have the opportunity to play business as well. This is fundamentally wrong, and signals wrong policies. Solar panels and wind turbines work automatically. And their power has preference on the grid, per EU regulation. So every power user can buy, own and use a lot of a shared solar or wind farm, to generate their own power. At cost price. What the cost price of self generated renewable power is, depends on the local regulations and their cost factor. Citizens have the cheapest money to buy solar panels and wind turbines. With the Dutch conditions and regulations, the self generated power from on land wind turbines is 1,9 cents / kWh Or 3,4 cents including depreciation costs. A German auction for 1 GW on land wind power, "for consumers", resulted in a power price of 4,2 cents. UK has much more wind than the Netherlands and Germany. So UK self generated power may be below 3 cents / kWh For a solar farm, the grid connection often is a very expensive part of the project. But when a wind and solar farm can share their grid connection, the solar farm can save a lot on this part of the project. Because wind and solar, often have their max output on different times. Simulations in the Netherlands showed that only a few percent of the possible output was lost, because wind and solar peaked beyond the capacity of the wind farm grid connection. In the Netherlands a family size lot of a shared wind farm costs about 1500 EUR. It will generate about 4000 kWh / y And 5000 to 6000 in the UK on many locations. The cost price per kWh with the Dutch regulations is: (EUR cent) 0.9 turbine maintenance 0.5 Grid connection 0.3 compensation for the landowner 0,1 local taxes and insurances 0,1 cent grid balancing cost with a energy company Total 1.9 cents / kWh

Redrow targets biodiversity 'net gain' at new developments

Pret A Manger doubles reusable coffee cup discount

This is good news. Having picked up several discarded single use drinks cups on the mountain up here recently I think this discount may go some way to relieving this problem but it needs to be both a carrot and stick approach. So how about charging people 50p for a disposable cup as well as offering a 50p discount if you bring your own. A 1 difference really would be an incentive and any money raised from the disposable cup fee could be used for charity work such as beach clean ups, mountain clean ups or other environmental work. Now to dig out my trusty steel mug :-)

Horizon scanning: Six innovations set to shake-up sustainability in 2018

The new kid on the block in 2018 will be Spinetic Energy Ltd''s wind-panels that do with wind what solar-panels do with sunshine. Linked together wind-panels form a c.6m high wind-fence that can be scaled to provide on-site wind and storage supplemented by solar. In the UK and many parts of the developed world the wind blows for 80% of the year compared to less than 20% sunshine. Wind blows at night-time when UK demand is at its highest. Conventional wind-turbines have become so large that they can no longer be used to provide on-site power, instead their output has to be exported to the grid.

Central Heating - is the future smart? - Sustainabilty Musings from the Cesspool of Life

@Iain - good point about the building trade. How we have gone from recognising and valuing the skilled trades to treating them like 3rd class careers is one of the saddest things about our society. We value people kicking pig skins, so called celebs and wannabe pop stars more than the people who build our homes. My grandfather was a Master Cabinetmaker and a member of the Guild of Trades and would be turning in his grave at the way his trade is now looked upon. I guess part of the problem is the push for University Degrees and also the consumer desire for cheap goods in the main. They say 70% of all Land Rovers ever built are still on the road but that nearly cost the company it''s business. We live in a throw away society and until that attitude changes people will continue to tolerate cheap goods failing as they are cheap to replace.

Central Heating - is the future smart? - Sustainabilty Musings from the Cesspool of Life

Thanks for the link to the smart thermostat experimentation. The blog and its comments remind me of some of the things I have come across while trying to balance conservation (of the building) and energy efficiency. In doing the heat required sums it was clear that making up the heat lost through air infiltration (what used to be called draughts)was at least as much as the building fabric loss so I have become almost obsessional about eliminating as many small gaps as possible as this is easier to do than insulate given my constraints. I''m also going to install a heat recovery ventilation system. What doing my barn conversion has taught me is that the level of detail needed to produce an energy efficient home is well beyond the skills of the building trades. It is strange that the most expensive thing most of us will ever own is built by the least formally trained set of trades. Over the last 50 years the motor industry has gone from building unreliable poorly assembled basic products to todays complex cars made from well engineered parts which rarely fail and need minimal servicing. You wouldn''t tolerate a car thermostat needing replacement every 6 months so why do we accept TRV''s and other home components failing so early.

Central Heating - is the future smart? - Sustainabilty Musings from the Cesspool of Life

Central Heating - is the future smart? - Sustainabilty Musings from the Cesspool of Life

@Philip - again I thank you for providing a different approach and one I had not discovered myself. I agree that by building new homes to such a standard we could massively reduce energy demand and discontinue the use of traditional central heating but to do this for existing domestic properties (retrofitting) does appear to not be a cost effective method, particularly for the older properties in the country. This article is about how we can make small but important changes to our current central heating system to make them more effective and efficient rather than looking for a "new" approach to home heating and based on my investigations into how I can make my home as sustainable as possible in the most cost effective manner (which is one reason I have discounted Air or Ground Source Heat Pumps for instance). However it is good to know there are alternatives available for those wanting to build a new home to be as efficient as possible. Perhaps PassivHaus could be the future benchmark for all new build houses in the UK.

Central Heating - is the future smart? - Sustainabilty Musings from the Cesspool of Life

Why not one single mention of Passivhaus in this piece? i.e. properly done in new build &/or in thorough refurbishing existing homes, there''s almost no need for Central Heating

Landlords to contribute to energy efficiency

Hang on a second here. Landlords are being forced to improve the energy efficiency of their properties is a good thing (in a way) but their costs capped at 2500 is not. I''m self employed so I am not eligible for any grants, subsidies or help with improving the energy efficiency of my home so why should a private landlord, who is making money from the property and also has the asset, be subsidised by the tax payer (ie me)? And why stop at Band E? Surely we should be raising the bar to the highest level possible so perhaps it would be better to say Band E minimum but improve by a minimum of 1 band up to Band C or better. A great improvement could be rewarded by an offset against tax for the year.

The Problem with Solar (and other Renewables) - Sustainabilty Musings from the Cesspool of Life

How about this for the idiocy of the Renewables market? Remember the Thermodynamic Hot Water system I mentioned, well it is NOT eligable for the Renewable Heat Incentive despite being MCS certified and being a form of Heat Pump. Why? No idea but this system is efficient (COP of 4 compared to 2.6 for Air Source Heat Pumps), provides 100% of hot water needs compared to 30% for Solar Thermal, doesn''t ned sunlight so works 24/7/365 and can even be fitted inside the roof in listed buildings (National Trust and Church of Scotland are users). If inefficient and unsuitable technology can receive subsidies from HM Government then this system should be able to get them too. Rant over, time to write to my MSP and MP about this.

Central Heating - is the future - Sustainabilty Musings from the Cesspool of Life

@Iain - another area where we could really do with getting into the 21st century, conservation area limitations. Surely it is not beyond the realms of possibility to allow homeowners like yourself to add insulation or replace old, leaky, single glazed sash windows with modern, double glazed efficient windows that look identical. If it doesn''t impact the general appearance of a building where is the problem? Best of luck with your Raspberry Pi system, if I can find the article I saw about a system based on this and IFTTT protocols I''ll upload the link. @John - having grown up in the SE I know all about hard water. A new tap would be encrusted in limescale within a few hours of use and kettles last a few months unless you descale them (Coca Cola works brilliantly at that by the way). The problem is that in order to remove the bicarbonate ions that cause the limescale takes energy or chemicals so in the long run which is worse? If there was some simple way to do it then I agree it should be tackled vigorously. And you hit the nail on the head, everything we use takes resources to make, move, replace and as 95% of our imports come by sea that means fuel oil. If we can prolong the life of appliances we should do.

Central Heating - is the future - Sustainabilty Musings from the Cesspool of Life

Hi Keiron Good piece. However vast majority of households in hard water areas do nothing to combat the wasted energy, increased equipment and appliance failures it causes. If they were encouraged to do so it would have a major impact on sustainability. Every time something breaks due to hard water scale it invariably has to be replaced using precious resources, energy and water to make it and then ship it all over the world to get to the end user creating further air pollution.

Central Heating - is the future - Sustainabilty Musings from the Cesspool of Life

This hits the nail on the head. Same thoughts been going through my mind because in a barn conversion like mine I have limited insulation thanks to conservation officer demands and a mix of underfloor and radiator heating. All the main control suppliers want to sell complex thermostats at high prices and then connect them to relatively dumb control. I too have been drawing up a spec for a better system based on a Raspberry Pi and it does not look too hard - but I need to get the conversion completed before spending time with a Pi working out optimal algorithms for temperature compensation and PID type operation from a central small screen controller.

UK firms 'cannot afford to ignore' ?14bn green fleet opportunity

The hot topic: Where does heating fit into a low-carbon electricity network? - The AECOM blog

Decarbonising heating is the elephant in the room when it comes to our energy demand. If we switch all our heating from "burning" things (oil, gas, coal, biomass etc) then how many GW of electricity are we going to have to find to meet demand? Currently the UK demands around 30-50GW but that is with only a small % of heating being electric. Even if we only have to double capacity that means 100GW required constantly. Most homes use significantly more than double their electricity demand to heat by gas/oil so it is more likely to be a 5 or even a 10fold increase in electricity demand. Time to tap into the reservoir of heat that surrounds our island nation perhaps?

Edible packaging and ocean-plastic shoes: Six of the best innovations to solve the plastics problem

Recycling plastic can only be performed a limited number of times. It merely delays the release of plastics into the environment - and, in the case of shredded plastics for fabrics, end up as micro-fibres which are far worse than their original counterparts. The ONLY sustainable plastics are those based on bio-materials that degrade naturally (or are edible). That includes bottle caps and sneaker glues.

New initiative to prove marine energy's potential

Tidal Stream is the way ahead as we have some of the biggest tides and fastest tidal currents anywhere in the world. The problem with Wave is we also have some of the biggest waves which has the ability to destroy anything we build, as was seen at Dawlish. I''d be interested to see the "pneumatic wave" system that used an artificial blowhole and the movement of the air within it from the wave motion below developed for coastal communities. Then we have also got to look at harnessing the vast reservoir of heat in the seas around our shores. We are blessed with a mild climate thanks to the Gulf Stream / North Atlantic Drift. Let''s capture some of that massive flow of heat.

Lidl goes 100% sustainable with bananas

Since when did Rainforest Alliance banana certification or Fair Trade certification = sustainable ? Neither certification purports to certify banana plantations as sustainable , yet this (purposeful?) misidentification persists in the media. I have been to numerous RA plantations, which still use toxic chemicals and are still monoculture on lands that used to be forests. Fair trade certifiers certify wage levels and not much else. The only truly sustainable bananas are those grown organically, without repeated clearing of the undergrowth and beneath a canopy of older trees. Such bananas are available, yet go against the industrialized system, created by Big Banana companies (think, Dole (formerly Standard Fruit), Chiquita (formerly United Fruit) and Del Monte), of getting fresh fruit from plantation to store 6,000 miles away in a week. Having worked with sustainable growers for more than five years, we found that it is likely impossible to get fresh bananas to northern markets and still be truly sustainable. People in those places should eat produce that grows locally, or be satisfied with banana products that can be stored for longer periods. Coffee and chocolate lend themselves well to true sustainable systems. Fresh fruit does not. But for journalists, please stop de-meaning the word sustainable , lest it become, like so many other watered-down concepts, meaningless.

Edible packaging and ocean-plastic shoes: Six of the best innovations to solve the plastics problem

None of these initiatives will get to grips with the problem. If we repurpose ocean plastic what happens to the creatures living amongst it, and is it commercially viable to collect? These are all attempts by big companies to continue using plastic without paying for the damage it does. Plastic should be replaced by less damaging materials, and where plastic is used, it must be taxed at a ratec2hich reflects the damage it is doing to the environment.

Edible packaging and ocean-plastic shoes: Six of the best innovations to solve the plastics problem

Good we tackle this matter. However i''m not convinced that edible plastic will solve anything. The fact that we people do toss plastics in nature, is a "normal" act. Sounds crazy maybe but since centuries we are used to throw or burn our waste. Furthermore, will we , and with we is every human being on this planet, de able to see, feel and undertsand the difference between some kind of edible plastic and the normal stuff? How hard is it to understand the difference between "ecological"plastics and standard plastics? They are all the same llok a likes. The action should go deeper into the supply chain, valuation of the waste and valorising the recycling chain. That''s my thoughts on edible plastics...

Report: Preservation policies could hamper Clean Growth Strategy's household efficiency plans

I have to agree and disagree with the comment related to windows below. If you have a Listed property or one in a conservation area, it is more than likely that the original glazing cannot be changed/replaced. Due to their age and character, they probably let a lot of heat escape and are draughty too. If you are complying with Part L of the Building Regulations related to the Conservation of Fuel and Power, then it requires the installation of secondary glazing with low-E glass in Listed Buildings. It is also highly recommended by Historic England and other heritage agencies. By installing this retrofit solution, good U-values can be reached (depending on the system and glass used) and up to 60% energy savings can be made. However, as a caveat to this and in agreement with the comment below you will only notice the thermal benefits of the products, if the rest of the building is fairly well insulated. Immediate comfort will be noticed and draughts through the windows reduced by 100% if it is installed. However this will vary from building to building, depending on what state of repair/disrepair it is in. Therefore, windows/secondary double glazing should not be discounted as part of the improvement works, as they can have a significant impact on the overall thermal properties and performance of a building.

Is 2017 the Year of the Flying Car? - Cranfield University Blog

Is 2017 the Year of the Flying Car? Sorry, no. Not 2017, not 2018, not 2019...never. Irrespective of the power source (and electricity is only green if it is made from renewables that are surplus to requirements, ie. not requiring additional fossil onto the grid to replace them), any heavier than air machine uses a lot more energy to fly than to roll along the ground. That''s not to start thinking about other environmental aspects such as noise.

Household recycling rates stagnate with UK set to miss 2020 target

It feels as if the elephant in the room is a coordinated recycling scheme across the country, we need to be able to put clear instructions on the packaging as how best to recycle it I.e please wash out and put in purple bin. But with wrap.org.uk saying that they are in consultations as to what colour bins should be used for implementation in 2025 it is obvious that nothing is going to happen any time soon. If the paper cup industry said they were making plans for 2025 there would be a huge uproar from activists like Hugh Fernley Whittington. Paper cups represent less than 1% of paper items produced, and paper represents less than 1% of landfill, we need mp s to wake up and smell the waste.

Household recycling rates stagnate with UK set to miss 2020 target

At my place of work, 0% of waste goes to landfill but at home, the local authority will not take most plastic food containers in the recycle bin. The inclusion of clear plastics, any bags etc. results in the bin not being emptied, which is incredibly frustrating. If you want to up the recycle rates, talk to the councils!

I would like to make the following comment to add to the webinar discussion on Thursday As a result of 10 years R & D Revaluetech now has a fully proven, commercially viable technology enabling manufacture of structurally engineered composite products using mixed plastic waste presently landfilled and/or dumped in our oceans. A wide range of inert products to be used in place of tropical hardwood, treated softwood and in certain cases concrete. This technology is simply waiting for investment to build the first of a series of plants in the UK and globally. An independent report estimates ongoing, sustainable markets up to 600/annum and globally up to 10 billion/annum. The UK Environment Agency is already using these to build groynes for coastal protection, sea walls and inland flood alleviation projects. The products are ecologically safe, are cost competitive and offer far longer service life than the traditional products they replace. They are recyclable, thereby offering whole life performance second to none.

Six million tonnes of waste could be 'left without a home' by 2030

Why does Edie keep posting articles support EFW or incineration. This report would seem to be at odds with others that suggest there is an overcapacity in this area to the detriment of other treatment methods of waste.

Six million tonnes of waste could be 'left without a home' by 2030

Energy from waste may in some cases clash with recycling of materials which is the real goal. Converting fossil fuel to waste and THEN burning it is no different to burning the fossil fuel used to manufacture the "waste" product?

Plastic pollution: Circular economy experts to discuss packaging solutions in live webinar THIS WEEK

There was a bio degradable plastic available in the early 90s that could be recycled but also broke down in landfill. its was too early for the market as oil ruled. Only one customer, a Japanese airline was interested in this product for food trays and cutlery. The patent was sold to Monsanto and as far as I am aware it has never been acted on or put back into production. This aside, we should all change our attitudes towards recycling and in this re-using where possible. In the UK we are particularly poor at recycling and most local authorities do not help this as they often do not have the correct expertise in this area. Landfill is too cheap and the government are not motivated to make changes because of the taxation they receive.

In practice: James Cropper's upcycling solution for the coffee cup conundrum

Thank you for the explanation Mark, which was helpful. I think I was focused on the fact that the plastic was made into tubing so it felt more like recycling into a different product but not necessarily a high value one. I''m still developing my understanding of upcycling. It was rather limited to things like taking a bog standard piece of furniture and transforming it into a more desirable piece through paint effects, luxury handles etc but still being able to discern what the original items was. I guess upcycling can be broader than that!

In practice: James Cropper's upcycling solution for the coffee cup conundrum

Clare, up cycling is taking a low value product, and making it into something more valuable, a paper cup may have a value of 2p, but as a Selfridges carrier bag, may have a value of 12p. Think one think we have to avoid is trying to make it into the same thing again, as paper cups have to be made from food grade material, and recycled paper cups are no good for that purpose, but are great for many other things.

In practice: James Cropper's upcycling solution for the coffee cup conundrum

Fantastic to see James Cropper who are only just up the road from PrintedCupCompany.com helping to provide a circular economy for paper cups. The Printed Cup Company support www.simplycups.co.uk for the collection of paper cups, the infrastructure is being created, maybe this will give the government time to sort out the real elephant in the room, a coordinated recycling scheme across the country.

Nissan starts construction on largest community solar roof in the Netherlands

About time we saw someone utilise the roof space of a building. Must just question the size of the panels though. You state "each able to generate 2.7 million kWh", really? Isn''t a million kilowatts a Gigawatt? And each panel capable of providing this much means the 8911 panels produce 240,597,000,000 kWh (or 240.6 Billion kWh which is the realm of terawatts!). Something doesn''t add up even to my atrocious mathematic skills.

Would a plastic tax help the UK become a world leader in resource efficiency?

It would have to be a hefty tax to have any impact at all. Deposit schemes are the answer for large containers and the German scheme enforcing manufacturers to take back their packaging has led to a free household collection of packaging waste. The Germans have been successfully tackling this for over 20 years. Typically for the UK any idea however half baked is launched with a prediction to "lead the world" . Is any other country so obsessed with leading the world and are these people so blind that they cannot see good ideas elewhere

The only H2 generators I have ever seen used distilled, deionised water which needed big chemical filters to make. or they use Methanol which contains Carbon atoms so any decomposition of Methanol will produce CO2. Perhaps you can enlighten us on this technology.

This will be used on conjunction with a combustion Hybrid rotary engine-generator as a power pack for EVs and also to power Off-grid houses, it may well be that the Grid will not be needed and there will be a massive cut in emissions.

EVs could provide 11GW grid capacity by 2030, research claims

How do they envision this working? It only works if every EV is plugged in and if the owner is prepared to allow their battery to be used. If, for example, the owner has arrived home after the evening commute (in winter) and has less than 20% charge left and needs to have a 100% full battery first thing in the morning the car will have to charge all night to achieve this. if someone comes along and says "oh we need to borrow some of your battery to smooth out a fluctuation" and the owner gets in to drive to work with only 80% charge he is a) going to be unable to get to work and b) be pretty pee''d off. Also what effect will this have on the battery life of the EV? Constant cycling of charge levels dramatically reduces the working life of chemical batteries. While Lithium batteries are less susceptible than Lead Acids they still degrade, particularly when cycled constantly between 20% to 80%. Not sure I''d appreciate having to change the battery in an EV because the power company have been pinching my charge on a regular basis. Just skeptical of the whole "EV as energy storage" thing and chemical battery storage full stop unless it is small scale like I have on a boat (12v Lead Acid with 64x solar panels)

The Problem with Solar (and other Renewables) - Sustainabilty Musings from the Cesspool of Life

Sitting in my front room looking out and wondering where has the mountain gone due to the low cloud, drizzle and general dreichness that is the weather in the Highlands I am convinced that solar PV is not viable in this part of the world. Yes theoretically a 4kwp system could provide almost all my domestic electricity but that is based on a theoretical amount of sunlight. Which given it is 12 noon and I have the lights on in the house as it is that gloomy ain''t going to happen in winter. Combined with the absolute lack of wind for the last couple of days, and I mean flat calm, zero on the Beaufort scale, not a zephyr lack of wind, that rules out a domestic wind turbine as well. So ruling out Solar PV and Solar Thermal along with Wind and pretty much ignoring Air and Ground Source heat Pumps due to the cost of such systems there doesn''t appear to be much left. However there is a glimmer of hope. I stumbled across a system that claims to be able to provide 100% of domestic hot water needs even in temperatures down to -10C, at night and even when it is piddling down!! Thermodynamic Hot Water Heating using a reversed fridge in a similar way to other heat source pumps but apparently more efficient. http://renewableenergy.scottishenergysaving.co.uk/thermodynamic-hot-water-heating/ This could allow me to dramatically reduce my heating oil usage, save money and reduce my emissions. Some serious investigations are on going so no promises but I thought I''d share the find with the collective

Balancing act: Storage and flexible energy vital to UK’s renewables tipping point

A glimmer of hope that the non-demandable nature of renewables necessitates a large backup from reliable sources, and good to see that vast battery installations are unreal. Nuclear is not just base load, it has become much more flexible, and will develop along these lines. Fast reactors, killed by Mrs T in 1989, will eventually emerge, but this awaits scientific understanding in political circles, pretty well totally absent at the moment. Those interconnectors; is it supposed that if we need more power, those at the other end will not need it too? Forget smart meters, they just cost the consumer, and place more power in the hands of the supplier. Richard Phillips

How business can help halt the rise in global emissions - The npower Business Solutions blog

Looking beyond company gates, is clear both that globally emissions are going up and we are in an ecological emergency now. To have any hope of preventing runaway climate change we (humanity) must change all the drivers that make global warming worse − things like devotion to economic growth, excess consumption, fossil fuels, deforestation and industrial agriculture. Big stuff! We are talking about a whole system change to a life-affirming global culture, rather than continuing on our present course of ecological self-destruction. For this to occur critical mass of the general public was ardently desire. Therefore the challenge for individuals, businesses, and NGOs that care about this is to communicate with our friends, business associates and the wider public about the need for transformative change, and how they can contribute to it within their sphere of influence. The Great Transition Initiative (www.InspiringTransition.net) is a platform to support such communication. We have ready to use communication tools including sample emails, guerrilla marketing tactics and Kitchen Table Conversations. We have a small international network, the most prominent of which is Paul Ehrlich (The Population Bomb). I invite you to critically review our approach. And if it makes sense to you, get on with communicating through your own initiative. There is nothing to join.

BT sets 87% carbon reduction target to help meet Paris Agreement goals

One easy win for BT would be to encourage customers to switch off their hubs when not using the internet. At present the installers say this cannot be done without damage. I have been switching off the office and home hubs when the internet is not needed without any problems for over five years now. There are many millions of such connections, and whilst each is small in total this is a large amount of carbon emissions. A quick, rough, estimate suggests c.1.7 GWh pa could be saved through this easy measure, or some - approaching one million tpa CO2e- depending on year of assessment.

Carbon price among policy wishlist issued by businesses at COP23

Best practices to reduce CO2 emission are great, AND they should be made mandatory for businesses. Office buildings should be made climate neutral, with solar panels, shared wind farms and local heat storage. All company cars that can, should be electric, powered by renewable power, without subsidy. All large emitters, fossil power plants, factories for steel, cement and fertilizer, and oil refineries, should apply CCS2 mandatory. Or pay at least 100 EUR per ton of their CO2 emission, caused anywhere in the world. This includes road, air and sea traffic. Let the CO23 principle be: a level playing field for businesses, by obeying rules that apply for everyone. Consumers are also voters in most countries, they are seduced by products, that give an advantage when bought an used. As Europa wants, give every citizen the right to generate their own renewable power, with the grid as a shared resource, to balance power generated with power used, and climate neutral power plants as backup. Coal is not the problem for the climate, CO2 is. Fighting climate change is VERY URGENT, we cannot wait until renewables have replaced fossil fuel. And by making CCS2 mandatory for all fossil power plants, their power will become more expensive than renewable power, which promotes renewables and also causes not more fossil fuel to be burned than really necessary

Coca-Cola bolsters sustainability targets for Western Europe

Car giants launch pan-European electric vehicle charging venture

Does Whitehall realise there are transport requirements outside of London too?

Automotive giants team-up to create Europe's 'highest-powered' EV charging network

Really, long distance driving is NOT what EV is about. Thats the daily commute. The regular low current home grid connection is enough. But it needs a smart charger that adapts to the local grid "unused" space. The rel new is that local grid operators digitally publish, in real time, how much empty space is available, so smart chargers at home can use that grid space, all together. And we don''t want a ugly steel pole at every home, but a unobstructive wireless charging point where users just park their EV. No pole and cable to demolish, no pole and cable that blocks people walking there.

The Problem with Solar (and other Renewables) - Sustainabilty Musings from the Cesspool of Life

Jon - that is true and I do agree that every kWh we can generate without burning matter is a good thing but at the end of the day if it isn''t financially viable for me to install solar panels on my roof or fit an alternative heat source then I am sorry but I''m not going to waste my hard earned money. I can reduce my carbon footprint more effectively by simply switching off lights, which also saves me money, or investing in newer more energy efficient appliances.

The Problem with Solar (and other Renewables) - Sustainabilty Musings from the Cesspool of Life

Yes but you omit the carbon savings from your musings. Every kWh of solar generated reduces that generated from gas (and coal , but that is almost zero now anyway because of renewables). There are more important things than money like the future wellbeing of our children and grandchildren.

The Problem with Solar (and other Renewables) - Sustainabilty Musings from the Cesspool of Life

Philip - simple answer to the first is neither are available for home use as far as I know but I am presuming that both involve burning so will give out CO2 and particulate matter. I was concentrating on the readily available options for domestic use primarily but I will look into these 2 now. Why no mention of the book? Again simple answer is I haven''t heard of it. Again i will see if I can find it and read it. Not sure Germany can be called a leading exponent of sustainable energy given they are switching off all their nuclear plants and burning more coal than ever before, despite all the wind turbines.

Diesel tax loophole 'thwarting' Government's clean air strategy

Some years ago, British Oxygen built trailers for road transport with the wall of the trailers filled with Liquid Nitrogen. I believe these were trialled by the chilled fresh food industry. I do not know when or why they are now not in use For the refrigeration compressor to be diesel fuel driven there must be good reasons!! I wonder why the unit cannot be powered off the vehicle electrics?. And why not solar panels to top up the electrics?

Study shows 44 of 51 UK towns and cities breach air quality rules

Having read the media carrying their version of this story on the 31st I have had time to consider the content 1 Fright [sorry freight] Many countries and cities are promising significant policies to hit cars and smaller vans. However a huge volume of traffic are trucks servicing the just in time delivery concepts. Many freight trains are pulled by diesel locomotives. How does the study conclude that only diesel cars need to be dealt with? 2 Electric Vehicles and charges Why are EV free in cities?. They cause just as much congestion as any other car. Similar question about vehicle duty. 3 Car Industry and EV IN many earlier attempts to kill off ICE powered transport the industry was an arch enemy, of the EV. I wonder why they are pushing the market so warmly?. Maybe that a higher sales price, increases the margin on each car. This would help explain why so many MPV and SUV are being sold. And the buyers do not seem to be worried about increasing their carbon footprint

Will the role of a sustainability professional ever become obsolete?

I can only agree with Chris that our sustainability agenda has never stopped changing, and we need to be constantly aspiring to the next peak... And we must not be content with the debate moving, I think it is for us to shape and drive the debate to ensure we are delivering to societal needs faster than topics become issues and problems. Good science and research is the key to our work to ensure the conversation about targets and compromise is on a factual rather than an emotional basis...

Shrinking solar deployment darkens UK's record low-carbon electricity mix

Yes and then we have days like today when wind is providing a paltry 3.2% of our demand due to the generally low wind speeds over most of Britain. Or days when solar can''t even provide 1GW of generation due to it being overcast across the country. Currently "renewables" are not reliable.

Top firms act on deforestation as UK urged not to 'turn a blind eye'

Revaluetech technology developed in the UK enables a wide range of structurally engineered composite products to be made which are already being used in place of tropical hardwood in construction of groynes to protect the coastline from erosion and inland for flood alleviation projects. The process uses short life plastic packaging waste, including that recovered from the ocean as soon as available. Not only are they less expensive they are far longer lasting, maintenance free and fully recyclable. Being inert they are not damaged by boring grubs and highly resistant against abrasion from sand, shingle and wave action. A real answer to a number of problems showing that plastic waste can be used rather than dumped or burnt to realise an enviable whole life performance in comparison to many hardwood, creosote treated softwood and concrete products to help achieve climate change targets.

Renewable heat legislation delays a 'significant threat' to UK's climate change goals

'Perverse' onshore wind policy could cost UK ?1bn

one often (always) gets the impression that in the UK politicians are a bit dim-witted over matters like these and prefer to play politics rather than deal with more difficult issues which might need a bit of technical understanding. I''m sure this is the case elsewhere but ours prefer to be world class procrastinators - because then you don''t make a decision - rather than world class visionaries and implementors. We continue on the path of mediocrity because it is safe and won''t lose votes.

Energy cost review: Dieter Helm's study calls for radical changes to Britain's energy policy

Prof. Helm is right - the government is too involved and should concentrate on policy and corrections, not taxes or detail. The cost of innovation and climate correction should be transparent and it is justifiable. Equally, the cost of supporting fossil fuels or nuclear should be transparent and explained. Most people are exasperated at the governments lack of foresight and action is either non-existent or too slow. The Smart meter debacle is but one example, and fiddling with domestic tariffs is another. The government should set the industry targets and leave them to achieve them. Like the railways, a failing utility should be taken back into public ownership and re-structured - with re-privatisation the aim. Shareholders would receive the current market value less the cost of achieving the missed targets. That should focus some minds.

Climate change minister pledges to 'break the deadlock' on CCS

Good governance is making CCS2 mandatory for all fossil power plants. This creates a level playing field and better competion than subsidies. And CCS2 is Best Available Technology, making it mandatory too. The Dutch Environmental Agency (PBL) found that CCS for coal plants is the cheapest method for CO2 reduction. But CCS crates a higher cost price for power, that is why the technology should be mande mandatory for all large emitters, and a CO2 tax on import power is required for fair power trading. Lack of these conditions, has caused rejections to install CCS. In the netherlands a new method for CCS is developed, that has several benefits. Traditional CCS captures CO2 from the smoke stack, and them pumps the gas in a old natural gas field. Separating CO2 from the capturing amines requires heat, and pumping the gas into the earth also requires a lot of energy. The new method, CCS2, als captures CO2 from th smokestack in the same way. But then uses the mineral Olivine tro react with the CO2, this results is a very stable substance, magnesiumcarbonate, and about 20% of the heat, the burned coa generated. This new heat, can be used to separate CO2 from the amines, preventing loss of efficiency. The chemical reaction between CO2 gas and Olivine powder is donein a Gravity Pressure Vessel, a double 1 km tube into the earth, where a mud of water, olivine powder and CO2 goes down and up. In the lower part of the vessel, temperature and pressure cause a quick reaction

'Perverse' onshore wind policy could cost UK ?1bn

Yes, it is correct that on shore wind farms do not need subsidy. In germany a recent on shore windfarm auction for 1 GW of wind power, resulted in a price of 0,042 EUR per kWh. In the Netherlands the costprice of on shore windpower is about less than 4 cents. That is why, citizens should get a chance to buy their own lot of a shared wind farm and generate their own power, at cost price. A family that needs 5000 kWh per year, needs to buy a lot of about 1500 EUR. Which generates their power for 20 tot 25 years. No subsidy required. The kWh prices includes net balancing cost which is about 0,1 cents per kWh, when large power companies have to compete for these contracts. It is good governance to create market conditions that large companies have to compete on the balancing market, for small consumers

Electric Vehicles?? - Sustainabilty Musings from the Cesspool of Life

Adam - Like most things in life there needs to be a balanced approach rather than "knee jerk" reactions. However did you read the article on the BBC website about Old Banger vs Diesel? What was astounding in that was a new 2017 Nissan Qashqi (Euro 6) emits 14 times the permitted NOx under real world conditions (RWC)!! And that an 8 year old diesel was cleaner than many new ones under RWC. If one is travelling within a city centre (say the Congestion Charge Zone in London) is there a need for anything other than EV or possibly PHEV? Does anyone in a city need a 3 tonne 6 litre 4x4? I do see a day when the vast majority of personal transportation is ultra low emission (I''m including EV as until all our electricity is supplied without burning something even they aren''t 100% clean) but I feel it is erroneous to simply look at EV as the saviour alone.

Electric Vehicles?? - Sustainabilty Musings from the Cesspool of Life

Another paradox for you Keiron is that depreciation has recently reversed on 2nd hand EVs due to the real world realisations that reductions in battery performance have been less than expected, so this actually means that they are faring better but that a 2nd hand vehicle costs more. So whilst cost is a barrier the performance over time is less so. Like you have said, the current utilisation of EVs definitely suits some more than others due to limited range and performance in adverse conditions but I see it more of a hierarchy of emission intensity whereby Fuel Cell vehicles and EVs sit at zero tail pipe, then you have plug in Hybrids, Hybrid drive, efficient petrol and finally efficient diesels. Both petrol and diesels have an important place in this transition period and it is wrong that new diesel vehicles have been somewhat demonized as they are a lot cleaner than older petrol/diesel vehicles. The ideal is that we continue the current empowerment that personal vehicles serve as efficiently as possible to a point where technological and socio-economic advances make the internal combustion engine cars redundant.

Climate change minister pledges to 'break the deadlock' on CCS

Much better to spend time and money developing Clean Hydrogen energy systems, this has to be easier than continued mining,drilling and excavating for Fossil Fuels at great costs and then at further continued Great Costs trying make a Pig Fly. CCS has been going to work for decades and every time it has been said "We now have the answers it has failed to work out. Stop trying to continue with the the approach and networks of Fossils Fuels and look for different options for the future. With Hydrogen there is NO need for CCS and no need for massive supply networks. For instance Hydrogen can and is being produced an Filling station forecourts. Does not take much further thought that it can be produced On Demand by a SAFE system in a garage or wall or balcony Unit. A balcony unit is already in use in Japan as a store for when the electricity is down. Can be done, But people do not want it to happen. Clean energy means a change in peoples thinking. Need a new system of taxation because if people are charging their car at home then tax on petrol is unfair.

Electric Vehicles?? - Sustainabilty Musings from the Cesspool of Life

Speaking to a friend recently who owned a small electric vehicle (the one that grows on trees) and he confirmed that battery range decreased dramatically in winter. Now fair enough he was living in Norway at the time so significantly colder than the UK for much of the winter but it still shows how "delicate" battery range is. He would get around 120 miles from a full charge in summer but this could drop to as little as 60 miles in winter due to lights, heaters, windscreen wipers etc. If you are driving around town this might not be much of a problem as you could always charge up every night or leave it plugged in all day while in the office (if facilities exist) but what if you commute into town every day, have no plug in at the office and do a total journey in excess of this winter range? You''re stuck? People will now say there are more and more "fast chargers" available and this is true but these will only take your battery back to 80% in 15 minutes. 80% of 60 is 48 miles. I''m not sure I fancy having to stop every 40 miles to recharge. Any battery can be fast charged to 80% but it is the last 20% that takes the time to recharge as the rate of charge gets slower and slower the closer to full you get, a little like Xeno''s Paradox. Additionally this pattern of draining a battery to empty (or near enough) then charging back to 80% and draining again will drastically shorten the battery life. A modern, well maintained liquid fuel engine can easily last 150,000 miles (or even more). That''s 30,000 charge cycles on a battery at 50 miles a charge (empty to 80% based on our winter range of 60 miles). I don''t think any current battery can last that kind of cycling. So while EV''s will play a part in transport infrastructure unless we have a plan for all the waste batteries or can somehow invent a 150,000 mile life battery I fear they will never truly be cost effective if you have to swap out the battery pack every year (10,000 miles or 2,000x 50 mile charges).

Report: Green gas could help fuel 15 million homes by 2050

Landfill is the 3rd largest contributor to methane emissions in the UK. This is primarily due to food waste decomposing anaerobically. The average UK household throws away approximately 1/3rd of the food it purchases. The problem with building infrastructure designed to capture methane from this source is it weakens the incentive to implement measures to prevent food from being wasted in the first place. The same applies to agriculture. The low hanging fruit from a climate perspective is to reduce waste and meat consumption (particularly beef). And use electrification via renewables to decarbonise transport and heat. Methane/biogas infrastructure may help with short term targets but will keep us hooked on carbonating technologies for longer, and prevent us from reaching 2050 goals.

Water - an under utilised resource? - Sustainabilty Musings from the Cesspool of Life

Ray - everything we do has an impact on the environment, for instance Wind Turbines kill birds and have an impact on peat moorlands due to the concrete foundations. If the authorities at Albi can power 10,000 homes from a single water turbine with minimal impacts then I see no reason why our own large rivers can not be harnessed in the same manner. It has been done in Guildford off the Wey Navigation with virtually no impact at all. I lived by the Thames for a year and the lowest flow rate I observed (as recorded by the upstream flow meter at Reading Bridge) was 28 cubic metres per second (Q). This equates to a potential 400KW at Caversham Lock. At 100Q, which I observed on many an occasion throughout the year, the potential is 1.4MW. 400KW would power approximately 100 homes or a hospital or a school. Every kw that is not generated from hydrocarbon and that can be sustainably produced should be. It is not beyond the realms of engineering to prevent wildlife (and rubbish) going through the turbine and many existing impediments to fish migration have already been overcome so not exactly difficult to avoid that problem. Even if we just looked at harnessing the volume of heat energy disappearing down our rivers it could make a dramatic difference to the UK energy balance/budget.

European Commission moves to Brexit-proof Emissions Trading System

These people are refusing to see that Hydrogen could be developed into the fuel of the future. Modified Oxy-Hydrogen for instance for arcraft. On board the EV On demand Hydrogen production linked to the needs of the engine will be the future. The present directions of BEVs and H2 Fuel Cells are far more difficult, especially with monumental high costs, for increased battery production and increased Generating capacity/battery storage, to get to scale to meet CO2 emissions targets. There has to be a serious look into Hydrogen combustion, since manufacturing Hydrogen engines for EVs does not need any significant increase in the Engine Manufacturing Industry. Given some quotes of $ trillions for Battery Plants and new power stations and Grid, to be able to maintain present production costs must be a massive pointer to look at new innovation which is being stifled by tentacles of the Fossil Fuels Industry. One particular H2 innovation, promises to be the Game changer. Hydrogen at 99.999% production unit able to be fitted for use on board a car and other vehicles.(Needs to be compact for restrictions in size) The development of a unit which produces 99.999% hydrogen has been aimed at Fuel Cells and was effective in stationary tests. There have been difficulties encountered with the Fuel Cell EV moving during road/track testing. It should be noted that Fuel Cell manufacture faces similar difficulties as Batteries when it comes to scaling up to produce multi millions of EVs to meet targets. Not only costs of raw materials but mass production has just reached 40,000 units per year from a new China Factory and 100,000 per year from what has been called the "Cambridge Method". Whilst these factories cost $ Millions 100,000 units may meet early demand however to produce any significant number of FCEVs there will need to be many such factories. 1,000,000 units per year = 10 factories and to meet targets by 2050 there will need to hundreds of such factories. The reality is that existing Global Engine Manufacturing Industry already has the capacity which allowed 60 million new vehicle sales in 2016. Developing a Hydrogen combustion engine would without doubt allow the "massive scale-up" required whilst avoiding the monumental costs of BEVs and FCEVs A Hydrogen combustion engine-generator EV with "On board On demand fuel production" would maintain existing prices for new cars and other vehicles. This factor alone would allow mass roll out of Zero emissions EVs. The fact that hydrogen on demand systems would allow onsite Off-grid generation will also be the way to decarbonise housing. Hydrogen is the Future, it is just not the present view of the best use of Hydrogen. Like Betamax v VHS the Fuel Cell is most efficient use of hydrogen however a H2 Combustion engine powered EV will be afforded by the masses.

Not the case in the UK. There are often droughts, rivers are at low flows and levels than ever before since privatisation of UK water companies bought by foreign investors, because of over abstraction by water companies to supply commercial businesses, car washes, golf courses and other water wasters. It is a fact that UK Rivers and Streams, boreholes and water tables are drying up after being sucked dry. The hydro- electric turbines placed in UK rivers kill fish, wildfowl and wildlife and stop or deter natural fish migration, plus they produce minimal electricity that only benefits the private individual that placed it there to profiteer.

World petrol demand 'likely to peak by 2030 as electric car sales rise'

The statement that "more efficient engines" is seriously question by the "On Road Testing" of two old cars. (BBC Program) An old Golf petrol versus a 10 yo Skoda diesel son and dads cars just as an idea to test the cars which turned into a program. The outcome must cause great concern, because when the data on these two cars was compared with the data collected from newer cars/engines the newer engines latest models were not as good as these two engines even though they had completed many thousands of miles. The concern is that the latest engines are promoted by Politicians and the Companies as being cleaner. It is clearly time that politicians distance themselves from these companies and the companies who carry out the original test producing figure which are a fiction. Sorry I keep saying this, there is only one way forward and that is Zero emissions EVs and I do not mean EVs which plug into a grid which is about 50% Fossil Fuel and likely to get worse with millions of EVs. (Hence fracking) Nor do I mean H2 Fuel Cells at over 50,000 it is clear why they are supported by the likes of Shell. Fuel Cells mean Oil will continue for decades. BEVs also have a number of hurdles facing mass take up and the costs can be seen as monumental. BEVs are not going to meet the target of 2050 because it will take at least 10 years to build out the infrastructure which will need Trillions of $ There is a need to develop a Hydrogen engine-generator, lowest cost option to have multi millions of Zero Emissions EVs on the road at affordable prices.

World's first floating wind farm opens off the Scottish coast

However, please note that "1MWh" Batwind is not going "to mitigate intermittency, lower costs and optimise the energy output from the wind park to the grid" in this context but rather it is a grossly inadequate capacity of energy storage for any 30MW wind farm. My recommendation is for energy storage of 5 hours times the generation capacity - so 5 hours x 30MW = 150MWh. It doesn''t have to be exactly "150MWh". The configuration rows in my calculator http://scottish.scienceontheweb.net/Wind%20power%20storage%20back-up%20calculator.htm?wind=30#wind range from 144MWh to 160MWh. But just to be clear. That''s someone in Statoil who thinks "1MWh" is appropriate and whilst I am a big fan of the Hywind Scotland floating wind farm project, I in no way whatsoever endorse, agree with, or would accept the ridiculous suggestion that a "1MWh" battery is going to be any use whatsoever. "1MWh" energy storage is a token, a gimmick, an unscientific suggestion that someone maybe came up with at a meeting, saying something like "Hey, maybe we should tack on some storage!". You know, without having done any calculations as to what is actually required. Then maybe someone else piped up "Yeah, that''s a great idea - let''s tack on some storage". And that''s it. There''s nothing else and there''s no excuse for it other than - "They simply didn''t know what they were doing".

World's first floating wind farm opens off the Scottish coast

Talking about storing energy from wind farms, did you know that only 90 miles to the west of Peterhead, near Inverness there is a site that could be developed to build a truly colossal pumped-storage hydro scheme? STRATHDEARN PUMPED-STORAGE HYDRO SCHEME (up to 180 GW / 6,800 GWh) World''s biggest-ever pumped-storage hydro-scheme, for Scotland? I have published a map which shows how and where the biggest-ever pumped-storage hydro-scheme could be built - Strathdearn in the Scottish Highlands. Energy storage capacity The scheme requires a massive dam about 300 metres high and 2,000 metres long to impound about 4.4 billion metres-cubed of water in the upper glen of the River Findhorn. The surface elevation of the reservoir so impounded would be as much as 650 metres when full and the surface area would be as much as 40 square-kilometres. The maximum potential energy which could be stored by such a scheme is colossal about 6800 Gigawatt-hours or 283 Gigawatt-days enough capacity to balance and back-up the intermittent renewable energy generators such as wind and solar power now in use for the whole of Europe!

World's first floating wind farm opens off the Scottish coast

Thank you and good luck to all involved with the Scotland Hywind floating wind farm project. I have suggestions for integrating wind farms into the electricity grid so as to provide power on demand whatever the weather. Wind, storage and back-up system designer Peak demand, wind and back-up power / energy usage and storage capacity calculator For the specification and design of renewable energy electricity generation systems which successfully smooth intermittent wind generation to serve customer demand, 24 hours a day, 7 days a week and 52 weeks a year. Offshore wind farms can use onshore energy storage facilities such as pumped-storage hydro but there are also possibilities to use offshore energy storage technologies such as power-to-gas, making hydrogen from water and storing it either in high pressure tanks on the surface or there is another possibility too, which I will mention now. Deep Sea Hydrogen Storage I''ve published a diagram which shows how hydrogen gas can be used to store energy from renewable-energy platforms floating at sea by sending any surplus wind and solar electrical power down a sub-sea cable to power underwater high-pressure electrolysis to make compressed hydrogen to store in underwater inflatable gas-bags. It''s potentially very cheap because no super-strong pressure containment vessels are required - the ambient hydrostatic pressure which is proportional to depth serves to compress the hydrogen gas to containable densities.

How P&G formed a new supply chain to combat ocean plastics

Paul, the bottles are recyclable through the usual plastics recycling infrastructure. P&G confirmed the following: "The bottles are recyclable in a real-world setting due to the color and clarity being targeted (clear/translucent). Sorting and recycling facilities will test the material after it is made, but the bottle will be identified as PET, kicked into the PET pile at MRF, and recovered for reprocessing."

Report: Preservation policies could hamper Clean Growth Strategy's household efficiency plans

I completely agree with Michael Mann below. I live in a ''B'' listed early 18th Century property in Scotland. Over the past couple of years, I have worked hard to improve my homes energy efficiency and have installed fantastic British sourced sheep wool insulation, and insulating plasterboard / wooden cladding. I have also invested in a biomass boiler. The property looks much as it did when it was built in 1729, however, it is now comfortably warm and as damp free as an old building can be. More importantly, I have taken the property from an EPC energy efficiency rating of ''G'' to a far more respectful high ''D'' rating. If I invested in solar thermal / solar PV, I would be able to achieve the governments 2028 band ''C'' target for all rented accommodation. I feel I have future-proofed my home without compromising its historical beauty. There are a lot of old stone homes where I live, and they are in general cold, damp, and with a lot of rot. However, tackling the issues has made me absolutely aware of how my home was put together and what the best options for my home were.

Report: Preservation policies could hamper Clean Growth Strategy's household efficiency plans

I am really glad that the Grantham Research Institute has highlighted this important issue. I have thought for a long time that listed building status and conservation zones are impeding energy efficiency. They are a problem for disabled access measures too. I think museums are for visiting, not for living in!

Fasten your seat belt, sustainable air travel is preparing for take-off - The Simply Sustainable blo

Since when is any bio fuel in quantity going to be sustainable from a production perspective and burning it in internal combustion engines of any type is still going to contribute to CO, nitrides and particulates. Electric flight is still many decades off - Jet engines produce in excess of 30MW each so battery power 3000 Tesla battery packs per engine per hour - not going to happen. Electric flight will be slow! It would be much better if the airlines and airfield operators got together to reduce stacking as that is unproductive flight and focussed on electrifying / de-fossilising airport operations - no more diesel generators for starting and leaving a gas turbine running to provide air-con. Using electric airside vehicles etc. There are lots of small wins to start the ball rolling.

Really exciting to hear this progress and promise in the airline industry. Do you think similar game changes Are coming in the Cruise-liner industry which is in rapid growth?

Report: Preservation policies could hamper Clean Growth Strategy's household efficiency plans

Windows do not save a lot... The real issues here are the floors, walls, and roofs. The government should undertake trials and promote solutions that allow and enable retrofits that do not destroy the character but make these buildings comfortable and healthy, as well as energy efficient. There are multiple issues here - radon, damp, and rot, as well as conservation officers who think their job means ''do/allow nothing contemporary''. We should accept that our world needs to modernise and that we cannot leave many hundreds of thousands of buildings to stagnate and decline whilst the world moves on (for the better). Character and appearance need not be sacrificed for lower carbon.

Excuse the stupid question, but is this new Fairy bottle recyclable in local Council/Borough kerbside schemes? Or does the enhanced recycled content make it more difficult to recycle?

Will the UK reach its carbon budget targets with the Clean Growth Strategy?

The Clean Energy Plan includes new nuclear power which is not low carbon, not safe and hugely expensive. Greg Clarke must rule out any new nuclear build and enforce a zero emissions policy on all decommissioning and waste contracts to comply with the 2012 Health and Social Care Act requirement to protect the public from exposure to nuclear radiation.

Government makes £557m available for new renewables projects

Keiron - Yes, tidal streams need no walls, but the geographically suitable areas for them are very limited. The Pentland Firth is almost ideal, but, like all tidal streams has its maxima and minima, zero. Standards of living have risen in keeping with energy availability at an economic price, I see no reason to place artificial caps on this trend. Fast reactors offer a very long term electricity generation system, using the 238 at present of little value. Long term let is hope that ITER or laser systems offer permanent solutions. Agree on the significance of the CO2 scenario. I like H.L.Mencken "The whole aim of practical politics is to keep the populace alarmed and hence clamorous to be led to safety by menacing it with an endless series of hobgoblins, all of them imaginary." Sums it up, I think. Richard

Government makes ?557m available for new renewables projects

Richard - one of the pluses of tidal stream turbines is there is no need to build a wall across an estuary so no sedimentation issue, which I agree is a major issue for any hydro scheme that relies on a dam (such as the Swansea Bay Barrage). Biggest issue really is to get everyone to accept we are all energy hogs. Our modern life relies on reliable, instantaneous energy and our demand for that energy has only increased. Up to now we have been relying on hydrocarbons of one form or another as they have been relatively easy to exploit. Trying to change the fuel source for our continuing energy demand is always going to be difficult as we have become accustomed to power being there all the time. CO2 is a convenient scapegoat as it can be measured and taxed. Energy or more accurately Heat is the problem. 7 billion people produce a lot of waste in the form of heat which thanks to the blanket of gases surrounding the planet can not escape so builds up. CO2 levels have been significantly higher throughout geological history (and significantly lower too). It is very "egocentric" to think the last 200 years represent the norm for Earth climate. In the last 425,000 years global temperature has been as much as 4 C higher than present and 8 C colder. In fact if you were to draw the average line across the last 425,000 years the global average temperature would be around 5 C colder than humans currently think is the norm. I agree and have little confidence in the politicians
