Cars burn fuel. 40% of power gets to back wheels

power stations burn fuel. maybe 55% efficient. lose power from generator to electricicty, stepping power up and down throught the burbs and power line losses. Lose another 20% of input power converting AC to DC for battery.

only saving grace is if car brakes regenerate energy to regain some power spent.

until power is generated by renewable energy, this is Troll environmentalism more than biodiesel.
