California's plan to reduce carbon emissions from transportation anticipates a mix of battery-electric and hydrogen fuel-cell vehicles. Recharging batteries from the electric grid is relatively simple, but producing hydrogen fuel requires a good deal of energy to split pure hydrogen out of other compounds. To ensure that the carbon footprint of fuel-cell vehicles is significantly lower than that of gasoline or diesel cars, the state mandates that one-third of the energy used to produce hydrogen fuel be from renewable sources.

Many electric-car owners start to think more seriously about the source of their electricity when they plug their cars in to recharge. And at least in California, data show that owners of plug-in electric cars have far higher interest in photovoltaic solar panels than drivers at large. Now a Minnesota energy cooperative is offering all-renewable electricity to the state's electric-car owners for the same price as that generated from fossil fuels, in a program it's dubbed Revolt.
