...AND CHEAPER...:

Leaf, Volt tests show electric cars cost less per mile to operate (Eric Evarts, Dec 8, 2011, Consumer Reports)

Electric cars may cost more to buy, but they're really cheap to run, according to our tests of the Chevrolet Volt and the Nissan Leaf.

The pure electric Nissan Leaf costs just 3.5 cents a mile based on the national average of 11 cents/kWh of electricity. That's less than half of what it costs to drive the most fuel-efficient four-door car we've tested, the Toyota Prius.  [...]

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.)

As today's technologies improve, prices decrease, and new plug-in cars are developed, EVs and hybrids will offer an increasingly attractive option for car buyers. And already, in terms of pure energy costs, the balance is in their favor.
