Don't forget that most electricity comes from fossil fuels so the car neither green nor sustainable nor renewable.
Forgive me if I'm being a bit presumptuous about your own beliefs, however, I feel the need to rant a bit here. I am simply sick and tired of people seemingly determined to attack or attempt to discredit anything related to green policies. I find it ridiculous that so many climate skeptics want to turn it into an 'us versus them' game where you have to tear down everything the other side supports.
I'm a climate skeptic myself. I'm skeptical that man has as much to do with climate change as many seem to believe they do. I'm skeptical of their models for the future. I'm skeptical that climate change will be as damaging to the world as they predict if it does continue unabated. I'm skeptical that policies such as carbon taxes will have a significant impact on preventing climate change even if all their models are right, much less enough to outweigh their economic cost.
Even with all of that said, you seem to be putting down the buying of electric cards. Okay you could go after the tax credit, but that's not the fault of the person buying it. No matter what happens to be true regarding climate change, it's hard to argue against reduced pollution and less dependence on foreign oil. If the market can support electric cars, then that's great!
Just because you're a skeptic, and against government intervention on the climate change front, doesn't mean you can't support a green personal lifestyle and try to promote such behavior in others. If anything, you should be more inclined to do so. That way, at least you'll have something to assuage your guilt over being obstructionist with climate policies in the case it turns out you were dead wrong.
