This is misleading. The original questionnaire questions were much more in the vein of whether the respondents think we should limit our own flying / meat eating. It did not suggest that government should impose top-down limits as is implied in the text here.
The only reason that solar is now viable without subsidy is because of the kWh price increase created by the renewables. Last time I checked its still so narrowly breaking even on battery storage and not worth doing. When the grid starts to have intermittent blackout because of too much renewables we''ll see batteries become more profitable.
Hi Elena, I couldn''t agree more and have been writing about these approaches to innovation in other places: https://www.edie.net/blog/Sprints-Thinkathons-and-Hackathons-Getting-creative-on-sustainability/6098664 https://www.dba.org.uk/human-centred-humanity-centred-design/ It would be great to discuss some time. Very best, Chris
Starlite should be a paint that is readily available. 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. You might even be able to improve upon them both.
"9 in 10 believe all councils should use the same framework..." "48% believe responsibility lies with packaging manufacturers.." Lets stop faffing around, copy the German system which has been working well for over 25 years. 1. Make a central authority responsible for giving EVERY household in the land a free packaging bin completely independent of councils. EVERYBODY has the same collection. 2. Force the manufacturers to pay a small fee for EVERY piece of packaging produced or imported to the central authority. These fees pay for the universal collection and handling (recycling) of the waste. How does this help? 1. Manufacturers are incentivised to use minimum amounts of packaging which are easy to recycle. If it can''t be recycled it cant be used - simple. 2. One bin for ALL packaging for EVERY house - simple. 3. No reliance on local authorities. They are completely out of the scene. 4 Collections organised by population density not local authority boundaries -efficient 5 Small businesses like restaurants producing packaging waste don''t pay trade waste It took 3 years for Germany to set this up. The UK will be "consulting" for 3 years and then continue as a bit better than normal.
Very interesting story, but lacking a couple of key points: 1. What is the comparable price for that bunch of produce, from traditional sources? and 2. What is the capital investment required for this installation, and is that costed in, along with the energy use, in the selling price? Supermarkets are famous for loss leaders. Is this any more than a way of getting positive publicity? The idea of this sort of farming has been around for decades, but has never taken off - for very good reasons!
How about installing solar panels across the roof space of the terminal and around the apron area? I see no reason why ground mounted solar panels could not be installed around an airport as they are no higher than any other signage around the field and can be kept a safe distance from runways. Given the vast acreage at an airport this would allow a huge amount of power to be generated (especially at somewhere like Bristol where it is sunnier than average). Then the airport really could claim to be sourcing 100% renewable power.
It''s a start but how about refillable versions of shampoo, conditioner, laundry detergent, washing up liquid and other daily essentials?
Rick, respect to you for doing all of those things. I''ve looked at solar for my house and it simply isn''t financially viable given where I live (wettest town in Europe) and solar water heating is equally non viable. I tried a thermodynamic HW system but it was a total disaster and has soured my experience of the renewables industry as a whole. I do source my electricity from a sustainable/renewables supplier and have fitted a smart heating control system, lagged all my heating pipes and optimised my hot water tank which has reduced my oil bill by nearly 20%. Right now Electric Vehicles still have a problem for me. They are either way too large for my needs and therefore expensive or don''t have the range to cope with the kind of remote driving I have to do on a regular basis (160 miles coast to coast through mountains). So I replaced my old petrol car (when it was written off) with a newer, more fuel efficient version increasing my fuel economy by 15%. Perhaps as range increases, costs come down and ultra fast recharge stations appear as regularly as unleaded petrol pumps I too will switch. But as my supermarket is an hours walk away and it rains a lot where I live most people might talk the talk but they don''t walk the walk. I have done it with my trusty 65 litre rucksack (made from synthetic fabrics) and honestly I''ll take the car every time, even the bus takes over 90 mins for the return journey (including the walk to the bus stop, the waiting and the walk to the supermarket). Problem is the hardcore "greens" are the ones screaming and shouting and to whom the powers that be seem to be listening to most. Common sense and scientific reason are being throw out the window for the sake of "being seen to be green". Just look at the hoohah over MacDonald''s straws for instance.
I would like to see the NFU champion the bicharing of all organic waste, which can then sequester the CO2 in the soil for thousands of years, while being a soil improver. It is simpler than carbon capture and storage, and far cheaper.
Hi Keiron, Thanks for your reply. Perhaps you should distinguish between the very small hardcore of deep greens that might or might not want to stop using all hydrocarbons and the much larger group that have a more pragmatic approach to the climate emergency. I''d count myself in the latter group and yes I do walk to the Co-Op for my shopping (apart from the stuff that comes in a van from Tesco Direct), I did trade our much loved MX-5 for a plug-in hybrid (Ampera) and we have fitted solar PV and solar thermal to our roof. I know I''m privileged to be able to afford the car and the solar panels, but much of this is about making choices. Driving an EV is no sacrifice at all - believe me.
Rick, I understand all about "carbon payback" but the point is the "greenies" want to stop using all forms of hydrocarbons if they have their ultimate way. After all they would love to see the Oil and Gas industry collapse given some of the hysteria they promote about the industry. The point is even if we stop burning oil and gas tomorrow, something that I personally agree we have got to do as much as possible, we will continue to need the Oil and Gas Industry to find and recover petroleum for many decades to come in order to produce the very products the "greens" want us to use. Can I ask you if you have decided to walk to the supermarket and carry all your groceries home on a regular basis? Or if you have traded in your ICE vehicle for an EV one? And do you have fancy solar panels on your roof?
Kids should be in school learning about the issues and how to they can help through understanding them. Screaming jumping up and down blocking traffic and the parents that drove them there/took day off to Make more pollution for others to learn about pollution. Weaponizing children to intensify the pressure of ill thought-out energy policies is the true crime here, I suspect by NGO''s and companies that benefit heavily from renewable incentives. Only way out of this is small modular nuclear reactors, the amount of money wasted so far on bird blenders and solar panels we''d be halfway to decarbonising the energy grid. France had the right idea and the lowest energy costs in Europe and the lowest carbon footprint.
Sutton United FC, of the Vanarama National League, has introduced plastic glasses at the bar that can be re-used over 100 times as well as an attractive reusable thermos cup for supporters. The club was also the first outside of the Premier League to issue a stand-alone CSR Report (2014) and has replaced its gas boiler with air-source heat-pumps as well as moving to LED floodlighting.
I know one should never feed the trolls, but I''ll give you the benefit of the doubt and assume your comment is genuine. Nobody imagines that we can stop using fossil fuels instantly and most of us understand that hydrocarbons drove the industrial revolution and continue to underpin our lifestyles. However it is quite clear that we need to get ourselves off this addiction as quickly as possible. We can all decide to walk more and drive less, to trade in the thirsty IC engine car for a hybrid or EV, or to consider investing in solar PV. The important question is how to motivate these kinds of behaviour change. As to the hydrocarbons embodied in cleantech products like wind turbines, why not educate yourself about carbon payback times? As an example the carbon payback period for a 1.65 MW wind turbine in India is 50 days and for a 25 kW solar PV system it is 144 days.
Ah but the "greens" want us all to instantly stop using fossil fuels so isn''t this music to their ears? Or will it prove once and for all just how important hydrocarbons are to our modern, technological lifestyles? Just a shame their beloved wind turbines need a lot of hydrocarbons for production and maintenance, their solar panels are made from petrochemicals and the wiring in their panacea Electric Vehicles are all insulated with plastic.
"GHG emissions associated with the human consumption of meat and dairy are currently estimated to account for 15% of the world s carbon budget. But with the global population set to surpass 9.5 billion by mid-century, that figure is set to hit 80%." How can anyone write such rubbish without realising how foolish it is. 9.5 billion people, i.e. 2 billion more than now, is going to increase CO2 emissions from 15% to 80%? So we will all be just scraping a living by subsistence farming? I don''t think so. If you want me to keep reading your stuff, please edit it sensibly and stop printing such foolishness.
I can quite understand that a cucumber lasts longer if wrapped. I would like to see it wrapped in compostable film so the wrap can actually be recovered, if possible, through composting. What I really cannot understand is how so much other fresh foods are wrapped when clearly not needed. M&S coconuts take the biscuit !
How do you need to treat, e.g. wash the food before human consumption?
Perhaps when we see our political leaders sacrificing their cars, jet flights and "grace & favour" homes, when they lead by example and fit solar panels or air source heat pumps, when they walk to work or switch to sustainable power. Then maybe we will see the kind of cultural shift away from waste and consumerism that drives the economy.
Firstly start by improving the home insulation of the current housing stock to reduce energy demand to heat our current homes. Then make all new homes built from yesterday comply with the very very highest energy efficiency standards so they don''t waste heat. Only then can you try to ensure all new builds use renewable/low carbon heating sources. Current housing stock simply is not suitable for Air Source/Ground Source Heating conversion as it doesn''t generate sufficient heat to do the job. As for railway electrification how about looking at Southern for inspiration. What England? Yes. Southern Railways electrified their network in the early 1900s using 1500v DC third rail. Trains today can do over 100mph without the unsightly overhead wires. Even the original EuroStar used 3rd rail before HS1 was built. There are hybrid trains that can run on 3rd rail or overhead too. This would allow electrification of the West Highland lines (Oban/Fort William/Mallaig) and the North Highland lines (Kyle and Wick) without destroying the world class scenery and at a fraction of the cost of overhead lines. Forget Hydrogen for transportation. It leaks out of everything and takes twice as much electricity to produce as you get back from it. Plus you need extremely heavy pressure containers to store a few kilos of the stuff. Better to cut out the wasteful production of a highly explosive gas and just power by electricity.
Now this is a project I can get behind. Seagrass is great stuff for marine life and life above water too. Snorkelling over this stuff is an amazing experience. However a small proviso if I may to WWF and Sky. Please ensure there are still areas for boats to drop anchor or make provision for boats to tie up by installing safe mooring points.
The ''Daily Mail'' 11 July 2019 reports that single use plastic can now be turned into electricity and hydrogen, both important in a near-zero CO2 economy, it can be used on dirty or mixed plastic, and leaves no residue. The University of Chester, in partnership with PowerHouse Energy, has come up with the process and Waste2Tricity is the exclusive developer in the UK and South East Asia. They intend to stop plastic being dumped in rivers and oceans by making it valuable, paying $50 a tonne to be put in their kilns. The process includes cutting the plastic into 5cm strips, the air is squeezed out, and heating it in a kiln at 1,000 degrees Centigrade which instantly melts and gasifies it. This syngas (synthetic gas similar to natural gas) has very low CO2 content and goes into a pressure swing absorption (PSA) which extracts hydrogen at two tonnes a day. The remainder of the gas is used to generate electricity in a gas engine. It is hoped that the patented technology will soon power the plant at Ellesmere Port, Cheshire, 7,000 houses on the grid in a day, and 7,000 hydrogen cars in two weeks. As excess energy from solar and wind turbines will have to be stored for peak use and for night time use, hydrogen is an instant way of providing such energy on demand, and the more the better. PowerHouse Energy say they have received a letter of support from the Japanese Ministry of Economy, Trade & Industry about their DMG technology, which is the thermal conversion of carbonaceous organic materials, which is converting complex molecules into simple, safe, molecules. In the letter the Japanese Government Ministry said it considers the DMG technology has many environmental advantages, and views it as a major competitor within the low-cost production of hydrogen industry. Professor Joe Howe, Executive Director of Thornton Energy Research Institute at the University of Chester said: We are extremely excited to be hosting the prototype demonstrator here at the University of Chester. The technology converts all plastic waste into high quality, low carbon hydrogen syngas which can then be used to power gas engines. A by-product of this process is electricity, meaning waste plastic can not only fuel cars but can also keep the lights on at home. Surely the world must wake up to this technology. It will make waste plastic valuable with it being able to power the world''s towns and cities, and most importantly, it can help clean up our oceans of waste plastic now.
One science survey I read said that there were not enough rocks capable of carbon capture. The only option is thus to replace all fossil fuels with renewables.
I sent Boris Johnson my self-funding near-zero CO2 plan as soon as he became Prime Minister, without reply.
