If you drive an electric car in California and recharge your batteries at home, you’re paying about $1.51 to travel as far as you could on a gallon of gas.
That calculation comes from a new federal website, unveiled Tuesday by the Department of Energy, that allows people to compare the costs of driving on electricity versus gasoline. The“eGallon” site is designed to make one of the bigger benefits of EVs — low and stable fuel costs — easier to understand.
“Consumers can see gasoline prices posted at the corner gas station but are left in the dark on the cost of fueling an electric vehicle,” said Energy Secretary Ernest Moniz.
