According to Consumer Reports, the cost of charging an electric vehicle (EV) is almost always cheaper than fueling a gas-powered car – sometimes by hundreds of dollars. But it depends on the type of car and where you live. An EV’s fuel efficiency can be measured in kilowatt-hours per 100 miles. For example, if electricity costs 10.7 cents per kilowatt-hour, charging a 200-mile range 54-kWh battery would cost about $6. Charging a vehicle that consumes 27 kWh to travel 100 miles would cost three cents a mile. The national average cost of electricity is 10 cents per kWh and 11.7 cents per kWh for residential use. In comparison, a gas-powered vehicle that gets 22 miles per gallon at a fuel cost of $3.50 per gallon would have an energy cost of 15.9 cents per mile.
