Earlier quoted context omitted.
Yah, but those people won't be using refined gasoline. It uses alot of electricity just to refine a gallon of gas.
According to this web page: http://www.consumerenergyreport.com/2012/03/21/what-makes-up... It takes about $0.20 to refine a gallon of gas, so ~2kWh/gal. Except, It obviously actually takes less electricity than that, because there are other costs to refining. Not a bad investment in energy terms, when a gallon of gasoline contains ~36.6kWh worth of energy.
Where on that page did you get the 20 cents? Didn't see that anywhere.
From this

It's more like 6kWh/gallon.
