More Thoughts on Electric Cars
Since there isn't a gas tank on an electric car, miles per gallon is rather meaningless. Perhaps a better measure for operating cost comparison might be miles per dollar (MPD).
For example, if gasoline were $3.00 per gallon and a car could travel 30 miles on a gallon of gasoline, then it could do 10 MPD. If the car could travel 60 miles on a gallon of gasoline, its MPD would be 20.
If a car (e.g. Nissan LEAF or Tesla Model S) could travel 100 miles on 24 kwh of electricity and electricity were 11 cents per kilowatt hour (kwh), it would cost $2.64 to go 100 miles, or do 37.9 MPD.
