The ONLY way that an "alternative energy" vehicle might ever beat
the odds and actually improve over the total results of gas/diesel cars
would be if it could do just a very limited number of energy
conversions, with very, VERY low losses, and could take advantage of the
economies of scale that go along with generating energy in big expensive
plants, rather than in small individual engines. Your local power
company can make a kilowatt of energy cheaper than a car can; and can
support technologies that make power generation cleaner than what you
can do in a small, portable system of your own. So, if you COULD charge
an electric car, and run on "store-bought" electricity, then that might
actually be an improvement.
Actually, IIRC, the net efficiency of an electric powered by a
Coal burning power pant might be much greater than any
internal combustion engine, in part due to high net efficiencies
at the power plant & in part due to far lower losses at auto,
not even considering such things as regenerative braking.
While this would probably result in lower CO2 net emissions
I don't think we have the infrastructure to supply the recharge
power to homes & businesses.
