In 2006 the filmmaker Chris Paine had an unexpected hit with the documentary Who Killed the Electric Car?, which detailed how General Motors abandoned its potentially revolutionary EV1 electric. Well, it could be time for a sequel. 2010 will go down as the year that the long-promised electric vehicles finally hit dealer showrooms. From GM's much-anticipated plug-in Volt to Nissan's all-electric Leaf, electric cars from mainstream auto manufacturers are now being produced and sold in real numbers. Electrics are still expensive and range-limited, and real expansion will require a network of public charging stations that has yet to be built. But the automobile world will never be the same. Which is why Paine is working on a new documentary: The Revenge of the Electric Car.
