Unless we build more nuke plants, you're basically switching from oil fired to coal fired. Wind and solar are still in the single digits on electrical power grid, last I checked. So you'd be buying a fossil fueled car, after all.
The production tax credit for wind power equipment production ended Jan 1, 2014 unless I missed the news to extend it again, one year at a time, and manufacturers mostly shuttered plants and consolidated, seeing that their market -- which only worked fiscally, with the credit -- immediately dropping off by huge percentages as the true costs would be what was charged to customers.
Your home of California has done well with wind, being second or third place at my last check, but many folks are surprised to find out Texas eclipses the second place State by triple.
Most utilities in other States offer customers the ability to pay more to buy wind power and feel green, and then the majority of that customer's power still comes from coal. Gotta read the fine print on those offers...
Big oil has its problems, but you have to admit that delivering a product with as much labor as oil to almost every American in the form of gasoline at a price (with road taxes removed) that is often cheaper than bottled water, or "energy" drinks, at the same store, in the fridge, on a per gallon basis, is a pretty impressive of an incredibly efficient delivery system.
Coal also has similar mass delivery system economies of scale. But you're mostly burning coal in an electric car. It isn't clean. If that makes you feel better...
