The term "zero-emissions" is borderline BS when the energy is coming from a source that emits pollution way off in the distance. If I remember correctly, California has been closing more nuclear power plants than it has been opening, so it while it's nice that our cars won't be putting out smog someday, we aren't going to take climate change seriously unless we move to nuclear.
To extend off that question, I've yet to hear an explanation as to how well the grid will tolerate millions of cars being plugged in all the time. During the summer California struggles to keep the lights on, so I'm wondering whether we will be investing in electrical infrastructure this time. Nuclear can help solve that. Same with natural gas to electricity conversion(like what Bloom Energy does).
