The eGallon is a new and more comprehensible way to compare the fuel costs of gas versus electric cars. The eGallon is the cost of driving an electric car the equivalent distance that a gas powered car would travel on 1 gallon of gas.
According to the U.S. Department of Energy, here in the Northwest an eGallon costs $0.84 versus gasoline at $3.87 per gallon. In most states, the cost per eGallon is about 1/3 that of gasoline. If the Chevy Volt and Nissan Leaf didn’t have $10,000 price premiums, one of our cars would be electric.
