I vote electric. Any fuel can be converted into electricity, and electric motors are far more efficient than internal combustion engines, therefore an electric car is the most efficient way to utilize any fuel.*This applies especially to the transportation of the fuel. The electric car is the only auto that refuels by wire. Sending electricity over the power grid is 95% efficient. Other fuels must be transported by truck, barge, or pipeline, all of which have much lower efficiencies.*These efficiencies are confirmed by marketplace prices. most electric vehicles burn electricity at the rate of 1 cent per mile, far cheaper than any other fuel. *The mass-market EV has been held back by battery technology, but research is finally giving us breakthroughs to solve this problem. Here are some electric cars in development right now. Some may be available as soon as next year:*From Europe: The Electric Mini - does 150 mph!
