A lot of vehicles in California are running natural gas. Not all are electric. However, with 220v you can recharge a Tesla in 3 hours, say when you go to bed after you cool down your house, but not AC and recharging at the same time. It can be done without shutting down the grid. Also Tesla has a fairly long range depending on model, from 200 miles to 320 miles and newer models are pushing 520 miles on a charge. So commuting can be done almost all week without recharging. Like I said, in a heat wave, charging can be done late at night when most AC is cycling down.
California is getting power from a coal burning power plant in Mexico about 3 miles over the border and another coal burner in Nevada. They are also getting nuclear power from Arizona. So yeah, they can support their grid, from outside the state. Hypocritical. However, this is how PG&E is solving the problem without going solar or wind. Another However, is PG&E are getting sued for starting wildfires on powerline easements, but this is because California won't let them clear the underbrush under their power line due to some rabbits or something living under them. Neither have they let them cut forest roads and fire breaks in the forests. So uncontrolled wildfires. Stupid is as Stupid does.
