My wife asked me last night if anyone has ever said how much is really saved buying a Tesla (or Leaf). You always hear people crowing about how much they save not buying gas, so I just assume the comparative savings are massive, yet I have never seen it spelt out. Where I live kilowatt hours are cheap on a North American level. I think 12 Canadian cents where I live. Assuming a person is not a total cheapskate, and only charges their car at free stations but actually trickle charges at home, how much does it cost say to get 100 miles on flat road?
The average rate in the U.S. is $0.132 per kWh (September 2017), which is the cost we use in the chart below
The charts are for $0.1287 per kWh and Gas @$2.73.2
