I'm not yet convinced about electric vehicles. From an economics standpoint, I can't see how they would save anybody money, when compared with a similar gas powered vehicle. And, from the "green" perspective, as long as so much power generation in North america is from coal- or oil-fired plants, you don't really reduce emissions. There may be a case for the reduction of smog in city centres, but you're just moving it elsewhere, not eliminating it.
Then, what about battery disposal after it has reached the end of its life? At this time, I consider electric vehicles to be neither economical nor particularly green. Of course, I could be completely wrong, but hey, my opinion is free.
