Running the numbers. I live in Massachusetts and sure enough, that is one of the bottom 10 states. My Honda CRZ hybrid gets about 40 mpg average over the year.

Running the numbers. I live in Massachusetts and sure enough, that is one of the bottom 10 states. My Honda CRZ hybrid gets about 40 mpg average over the year. The price of gas, price per kWh and the number of miles are about right. Gas: 12282 miles @ $2.14/g and 40 mpg is $657. Electric: 12282 miles @ $0.191/kWh and Tesla P85 85kWh 285 mile range is 3.35 miles/kWh for $700. Basically a wash in a state ranked as 47th with a decently high mpg car. Price difference on the car is substantial though. $66,000 vs $23,000.
