I didn't realize the extent to which you were entrenched in the environmental religion. Is that accurate though? What about the disposal of the batteries? Are all charging stations powered by solar or are some on another type of grid? I don't know the answers to these questions. How harmful are vehicle emissions these day?
I'm biased towards electric vehicles because of my senior design project, but I've wondered these things also. I wouldn't buy an electric vehicle if I had to charge it from the grid from home ... I'd have the solar panels in place also. Otherwise, I'm not sure how much money you're really saving because what you aren't spending in gas you're spending some or all or more in electric costs.
The disposal of the batteries are certainly an issue ... but is it a net positive or negative when you factor in oil and gas drips from cars, or the larger catastrophes like BP and Valdez? Taking everything in aggregate, I would think the batteries would be better, but I'm not sure.
Regarding emissions, I don't think they are as bad anymore as they used to be from the cars, but you also have to factor in the production of the oil and gasoline ... just as you'd have to factor in increased emissions from power plants for cars being charged from the grid.
I've never seen a thorough analysis of all of those factors.
