The US electrical infrastructure cannot handle even a significant minority of the US auto fleet being electrified. It isn’t just a lack of generation capacity, there are significant constraints in transmission capacity as well.
I’ve been a proponent that the fastest way to achieve a significant increase in US auto fleet efficiency is to use modern diesel engines. The barriers are the idiots in Detroit and the environmentalist who stupidly believe that all diesel engines are exemplified by the soot-belching Detroit two-strokes in muni bus fleets.
“The US electrical infrastructure cannot handle even a significant minority of the US auto fleet being electrified.”
Think of what would happen if the lights went out because of problems at the generating facilities.
