For every watt of power that is charged into a battery, you only get a fraction back out. That watt required energy to create it. That is in big part why electric powered cars and not as efficient as the tree huggers might lead you to believe.

Nuclear power is stil lthe cleanest, most efficient source but I don't want it in cars.
If they can develop a battery that is much more effcient that would be the answer.
