"Sherry Boschert does a great job of showing how shifting to hybrid plug-in cars can sharply reduce gasoline use, dependence on imported oil, and carbon emissions. If we simultaneously build thousands of wind farms across the country, feeding cheap electricity into the grid, we can then rum our cars on wind energy - and at a gasoline equivalent price of less than $1 per gallon. What are we waiting for?" - Lester R. Brown, President, Earth Policy Institute
