How much does it cost to commute to work or drive across town? The price of gasoline is posted at every corner gas station, but what about the cost of driving on electricity? The Department of Energy’s eGallon provides a quick and simple answer to this question and allows electric vehicle (EV) drivers to see how much they can save on fuel by using electricity instead of gasoline.
The price of an eGallon tells consumers how much it costs to drive an EV the same distance you could go on a gallon of unleaded gasoline in a similar car. It’s that simple. We take the average distance that a gasoline-powered vehicle can drive on a gallon of gas (28.2 miles for comparable 2012 model year cars), and then calculate how much it would cost to drive the average EV that same distance. Because electricity prices are a little different state to state, our eGallon tool shows how much an eGallon costs in your state, and compares it to the cost of gasoline. As you can see, on average, fueling your car with gasoline costs roughly 3 times more than fueling with electricity.

It doesn’t tell the whole story…
As you can see in the chart above, the cost of electricity is a lot more stable than the cost of gasoline. That predictability is a real benefit (especially if there’s a war in the Middle-East or something like that), but there are others. [...]
Plug-in vehicles are mostly charged at night when time-of-use rates can be way lower than they are during the day and during peak time. [...]
On top of that, free ways to charge are popping up all over.
