It takes more electricity to drive the average gasoline car 100 miles, than it does to drive an electric car 100 miles. A gas car at the US fleet average of 21mpg will consume approximately five gallons of gasoline which took 40kwh (5 times 8)of electricity to make, to drive 100 miles. An electric car will use approximately 30 kwh of electricity (3.3 miles per kwh) to drive the same 100 miles.
Although this argument makes a seemingly stunning point, I'm not so sure his comparison is valid here. He calculates the amount of electricity needed to make a gallon of gas, transport it to the station, and used by the station, but then he seems to be comparing it to the amount of electricity used
only by the car. To be fair, I think his electric car figure should include the amount of electricity used to make the electricity (surely the powerplant uses power), transport it to the car (transmission losses), and used up by the station (charger). IOW, how many kwh are actually in a kwh used by the electric car?
