I don't know what percentage of electricity generated in California comes from renewable energy. If it's not 100% renewable then the EVs won't be Zero-emission either! Let's not even talk about range anxiety, charging times and long queues at the charging stations during a long weekend. If Hydrogen can be manufactured/extracted efficiently, that's definitely going to be a lot better than EVs. At least there won't be millions of used batteries to be disposed.

Presumably they hope to use wind, or solar, or some other power generation technology. That is one of electric vehicle's actual points of benefit; the power generation source is modular.

Yes, that's the hope. Less than 20% of the electricity is produced from renewable sources in my state (Victoria, AU). If the number of EVs increase that's just going to put more pressure on the grid and will require burning more coal. I don't know if the pollution from cars is worse than burning coals in a power plant. I'm guessing it's not. I'm hoping for hydrogen as the future. There is company working on Hydrogen here. Even Toyota and Honda have been working mostly on Hydrogen not battery based EVs. I've nothing against Tesla. In fact I admire Elon Musk as an engineer. But given the choice I'll probably go with Hydrogen fuel cell cars if it can be made readily available like Petrol.
