Electric cars will take ~30 years to transition (~10 years before almost all new cars are electric, and then another 20 years before the old cars are off the road). They will increase electrical demand by 20% over 30 years, or under 1% a year increase to demand.
The US increases its generating capacity by about 4% per year. (50GW added per year, 1.3TW total).
I don't think so, the adoption rate has done nothing accelerating since WWII. Once EV will be mainstream enough the switch will probably be quite brutal.
I don't think it is economically viable to maintain two sets of power distribution (electricity and petrol) at the same time so countries will probably "push out" traditionnal petrol stations once they think EV distribution is okay enough
The other day I was at a Target parking lot plugging in the EV at an island of about 6 superchargers. I looked over the rest of the parking lot at hundreds of ICE cars and it just struck me that getting the whole fleet electrified has got to be a substantial power demand increase, but maybe not. Which raises the question, what the heck is all the power being used for? :-)
The easy answer is bitcoin, AI & data centers. Those are noticeable because they're new. That's some of it, but AFAICT it is mostly air conditioning. Hotter days with more places being conditioned.

EV's are a very small part of demand increase.
