The amount of concrete going into hinckley C is mind boggling.Coal makes up about 10% of the USA's power generation. In the UK renewable energy is a lot higher, up to 40% and is climbing annually.
E=mc^2 doesn't show that at all - the full equation would, but it'd more appropriate to use Newton's equations.
Manufacturing an electric car is very environmentally impact, but so is making a petrol or diesel car. To make this an 'excellent breakdown' you'd actually need to compare the two life cycles. Ditto for the discussion on solar panels and wind farms - building a coal/gas/nuclear power station isn't without significant resource usage! Easiest way to compare resource use is cost, and renewables have been beating conventional energy on cost for years.
As I understand in, when assessing the lifetime energy costs, electric cars become better after 80k miles or so. Which is a slight improvement when car last ~150k miles. This should drop as efficiencies in mass production kick in, where ICE have a big head start.
A significant benefit not mentioned is removing air pollution from population centres.
Anyway, I wouldn't rate this as 'excellent'.
There was a item on R4's "more or less" program which looked at how long it took for an ev to pay back the extra carbon costs of build.
I think they came up with 2 years of average use in the UK, though much more in the USA due to less renewable energy sources as you point out.
And if you charge off your own renewables....
Boring in what sense?Friend has just got a Kia ev6 after having a bmw i3 little thing for four years. She said it’s a better car in terms of range etc but it’s so boring to drive
It goes like stink.
