Because of scale, an EV running off of coal-powered electricity is better for the environment than a gas powered car, not even taking into account emissions that aren’t carbon dioxide.

That aside, there are a variety of electricity storage mechanisms that have been becoming more and more efficient, like normal batteries, hydrogen electrolysis, and pumped water. With some clever engineering, solar power works at night.

I wish California would keep their nuclear plants open, but the loss of them is not an impediment for electric vehicles.
