I generally like using financial comparisons as a good proxy for "efficiency"

Using this proxy, Electricity costs me about $0.12 per KWH this equates to about $5.63 for the equivalent energy in a gallon of gasoline. That's why I asked.

THat's right, but as I said, your electricity cost includes the cost of pollution, as they must meet standards, while the cost of gasoline does not. The cost of your CAR included some of that price.
