Electricity can be created IN CARS from hydrogen or ethanol: Nissan Ethanol Fuel Cells cars as example
Additional note: These cars can also feed electricity to national electricity net. To change present fossil energy using vehicles to normal electric cars would mean high additional investement in electricity generating power plants. This would become unnecessary if new cars would be self electricity generating fuel cell cars; in case of shortage car owners could sell electricity to the net at price of the day. Large group of privately owned ethanol fuel cell cars would then compete on the market against coal and nuclear electricity plants. In future electricity can possibly be generated in fuel cell cars also from biogas.
