Electric Cars
In this photo taken Monday, July 26, 2010, David Sandalow, the Department of Energy's Assistant Secretary for Policy and International Affairs, poses by his Toyota Prius plug-in hybrid vehicle at his home in Washington. Sandalow's shows the lithium ion battery of his Prius, which was converted two years ago to allow him to recharge the battery from an electric outlet. The car gets more than 80 miles per gallon and lets him drive 30 miles on a single charge. (AP Photo/Charles Dharapak)
