I'm not advocating gasoline, there are better, renewable, alternatives than electricity for transportation purposes however, ones that use 1/5 as much land as their solar counterparts, do not suffer range problems, or inefficient weight problems or outrageous cost problems for batteries that are 15 years away.

Regardless, I never said the heat conversion in electricity is significantly more efficient. By the time it gets to your outlet electricity is already down to %30 efficient, then you have to run a motor, and a controller, and charge batteries, and discharge batteries, and shlep those heavy batteries around everywhere, (the more range the more batteries).

Electricity is great in a dollars per mile sense if you ignore the initial costs, but is a lot less efficient than people are prepared to admit.
