WASHINGTON – JULY 19: An electric cable is attached to the side of a Chevrolet Volt vehicle during a viewing on Capitol Hill July 19, 2007 in Washington, DC. The Volt is a plug-in electric vehicle which will run its first 40 miles without using any gasoline, and then the battery pack will be re-charged by a small internal combustion engine that runs on gas, diesel or ethanol when required. The vehicle is expected to be on the market by 2010. (Photo by Alex Wong/Getty Images)
