YOu will be switching one fossil fuel for another, petroleum gasoline for coal and natural gas.
It's going to take a while (decades) to get wind power up to a significant portion of the total power output for the U.S. Unless the car owner wanted to buy his own smaller wind-turbine (not sure how much they cost (assuming he lives somewhere that will allow such installations)).

I think JD. Powers estimate of when GM will be selling 300,000 per year (by 2014) is a bit of science fiction, really.

But still, it is a technology worth pursuing.
