"The useful thing is the amount of new generating capacity required if the whole country move to EVs is essentially zero."
My home solar is quite large and my battery storage is usually enough to make it through the night. That said, I don't have enough power generation or storage to take on the additional power in the day to later charge an EV when I get home in the evening. Although if EV's keep improving I might one day upgrade the system.
Even still, I need a gas powered car in the family too for when we go on long trips and such. My take on EV's are they're good for some things if you already have a certain scenario (in my case I have extra solar power half the year that I'm not consuming and could enjoy that going into something useful like an EV). But they can't totally replace gas cars.
And don't get me started on Ford having the audacity to refer to that grandmother's car looking hybrid as a Mustang!
Regards and thank you for your thoughts!
