there is a nice comparison of vehicle costs from a reliable third party source:

In miles-per-gallon terms, we found the Leaf gets the energy equivalent of 106 mpg, based on efficiency of 3.16 miles per kilowatt-hour of electricity. If you charge it at national average electric rates of 11 cents per kilowatt hour, you’ll pay about $2.42 to charge the car. (Admittedly, electric rates at our test track in rural Connecticut are almost double that: 19 cents per kWh. Along with New York, Connecticut has the highest rates of any state in the continental United States. But even at that rate, the Leaf costs about 20-percent less than the Prius to operate and about half the cost of the Corolla.)

It is more expensive to make it work in say, Hawaii (~20cents/KwH) to drive electric versus say WA state where it costs ~8 cents/KwH on 80% hydro based energy.
