The problem with all the data being published about the "new" electric cars is putting it into meaningful context. For instance, the statement that 1 gal gas is the energy equivalent of 34 KWh is true but mostly irrelevant when talking about cars. An electric car wastes about 10-15% of its energy as heat; an ICE wastes about 60-70% as heat. That means that 34 KWh will drive your electric vehicle as far as 3-4 gal of gasoline.
The Leaf advertisement gets to the heart of fuel economy comparison by showing miles per dollar of fuel.

The label estimates a charging time of 7 hours on a 240-volt charge. Cost estimates were based on 15,000 miles per year at 12 cents per kilowatt-hour
