  1. Well it didn't come from Wetherspoons so maybe it seems that way. There aren't many intractable problems in recycling. The two major ones are dispersion, where something is dispersed into the environment, maybe pollution is a better word. Then it becomes hugely difficult to concentrate it and therefore expensive to remove it. PCBs, CFCs, mercury and microplastics are examples of this. The other is nuclear waste. Pretty much everything else can be dealt with in some fashion or other, provided you aren't stupid enough disperse it in the first place. Whether people/businesses actually want to go through that recycling process, that's another issue.
  2. All technologies/products are "foisted" on the world before the recycling is worked out. The recycling is worked out when there is enough incentive to do so. The thing with car lithium batteries is that it is going to be some time yet, maybe at least 10 years, before the batteries are available in significant enough quantities for recycling to be necessary, and during that time there is going to be plenty of opportunity to come up with recycling methods. There is a ton of information on the web re this. It will probably be the second generation of batteries that are actually designed to be recycled from the start, building on lessons learnt from trying to recycle the first generation. There is plenty of stuff on the web about what Telsa is going to do re cycling when the batteries are available in sufficient quantities. They just aren't atm.
  3. I can imagine Elon Musk in his office at some point being told that electric vehicles only had a small chance of replacing ICE cars and it wasn't worth building one because they would never be able to make or sell them in enough volume to make a difference.
  4. Fine. Where are the better figures then ? In the absence of them those are the ones you have to go with. I would guess the estimate is not too bad, unless you can provide some error bars. We can double our installed solar capacity and cause no issues at all re the electricity supply mix. So best to get on with it. I don't see the fact that electricity only makes up some % of the total energy consumed as a reason for not doing something about trying to improve the overall nature of our energy supplies.
  5. I have no idea on the stats. I feel irritated by solar and you're right it's the governments fault. After a strong start in 2013 removing the support killed it. I think we could double our installed capacity without it having too much of a problem in terms of the energy mix. I suppose the good news is that approx. 20% of our energy at this instant in time is being generated by solar.
  6. While CCGT is such a large % of the energy mix and can be pretty much ramped on and off at will, this is not a consideration. It could be a problem in a few years time if the % solar gets a lot larger. But the installation of solar has stalled considerably over the past couple of years : https://en.wikipedia.org/wiki/Solar_power_in_the_United_Kingdom
  7. Depends where you look on Gridwatch. That is probably the instantaneous generation. Wind varies quite a bit, like solar. Wind generation during the summer months is pretty poor, but during the winter months it ramps up considerably. Solar of course is the opposite which is why the lag of solar installtion vs. wind currently is concerning.
  8. I don't think that is true. We generate far more from wind than biomass. https://en.wikipedia.org/wiki/Wind_power_in_the_United_Kingdom
  9. Climate change is the first real test of the global society, that has proved pretty inept so far at solving tough global problems. In small highly populated countries I think there are benefits to reducing fossil fuel usage that go beyond climate change. For example not all countries have access to the fossil fuels, and when you switch over you get better air quality and less enviromental problems such as traffic noise. Still I don't see the climate change issue as being one that can be truly solved with our current government structures. It's going to hit us and we are going to have to deal with the consequences. Countries like China may act like they care on climate change, but I'm pretty much convinced they don't give a stuff provided their economy isn't being damaged and they manage to make profit out of countries who are trying to do something about it along the way. Maybe it is just as worthwhile building London on stilts as it is putting money into wind turbines.
  10. https://www.bbc.com/news/business-58066660 This made me laugh a bit. While these firms are attempting to shut coal plants down, China is building coal capacity at an enormous rate. https://www.theguardian.com/environment/2021/jun/30/five-asian-countries-80-percent-new-coal-power-investment https://www.independent.co.uk/climate-change/news/china-coalfired-power-plants-iea-clean-energy-b1858236.html Is China's coal power program the biggest threat to preventing climate change ?
  11. Ford Focus diesel. 2012. 55mpg. It's been an OK car. Parts are dirt cheap. Tax is 20 quid a year. Only had one significant thing go wrong on it, an injector. Probably not a car to get if you are doing short runs. And if you get one s/h there is always the possibility someone has clogged the dpf. with short runs. Still, the tax saving builds up and over the time I've owned it I have some significant advantage in tax over the petrol which would pay for some major repairs if I was that way inclined.
  12. Fat people place a massive cost on society though. They are also pretty hard to sit next to on a plane.
  13. Shows quite nicely why the government won't bother trying to convince unvaccinated older people to have the vaccine. Effort on doing this is totally wasted.
