It would be better with distributed generation like solar. The idea of a central generation point and transmitting it long distances is just not the best way (single point of failure/attack, losses of long distance transmission, often dirty and/or dangerous). Having lots of little solar farms all over (or even private) is better. I’d imagine most of Californians could provide their own EV needs if you have a large enough roof.

Take this with a grain of salt …. I’m not a power engineer but I did stay at a Holiday Inn Express last night.
