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.
We definitely don’t realize how often we sit idle at lights, etc. That destroys MPG in a gas vehicle. In an electric the vehicle doesn’t even lower the kWh since it’s not providing energy to the motor(s) while idle. This is an easy to see comparison in a PHEV.
