Electric Cars Can't Take The Cold
 

Evidently, temperature has quite the effect on the distance that an electric car can run. The trouble is, except for Oregon, none of the states have California's temperate weather. The batteries used by the greener cars generate electricity from chemical reactions that work less efficiently as temperatures drop. In tests conducted by the American Automobile Association, an electric car that ran for 105 miles at 75F went only 43 miles at 20F—a 60 percent reduction in range.
