EVs are three-times more efficient on average than a typical internal combustion car meaning big savings. A Nissan Leaf for example, gets an EPA rating of “mile per gallon equivalent” of 129 city, 102 hwy, 115 combined.

Factoring average utility rates, estimated electricity costs to run it are about equal to a gas car if the gas car owner bought gasoline for 73 cents per gallon.
