Too little too late. How can a vehicle be "zero emission" anyway, unless the entire production and supply chain is also zero emission.
Yeah, its almost like this is one step in a long, complicated process of getting the world off of fossil fuels, or something?
Anyway, an electric car can run off of pretty much any energy source. It's much more expensive to make gasoline from sunlight or nuclear power than charging a battery.
(And, if you're wondering, yes, making gasoline from sunlight (biofuels) is a thing, and no, it isn't practical, and yes, people DO try.)
