How Much Does It Cost to Charge an Electric Vehicle? (A comparison at home and on the road, with gasoline)::Few people know what a kilowatt-hour costs them, so they don’t realize how cheap EV home charging is versus gasoline. On the road, it’s more complicated.
Even if you have an EV charging on a shitty coal power plant, it’s still vastly more efficient than putting a small, personal power plant in a car and carrying around gasoline to burn. A modern EV uses the equivalent of about 3 gallons of gas to go 300 miles.
