Not quite true. The electricity used by an electric car does -not- "come
from regen" [erative braking]. This is a clever technique to recapture a
bit of energy when braking. To believe otherwise is akin to believing in
perpetual motion. The vast majority of the energy an electric car uses
is from either a power plant [the 'grid'] or from the on-board gasoline
tank that powers an internal combustion engine/generator.

That's why I said "in hybrids" when I mentioned regen...

The other concern is the losses in the grid distribution. We use oil
based fuels to generate electricity at a conversion loss and then lose
more in line losses. The emmisions in today's ulev cars are getting
down there. I guess I'd just like some common sense inserted into the
discussion and some real energy balance calculations made to help
clarify things. It seems that the politicians and environmentalists
aren't too interested in other scientific input.
