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.
The gas you burn in a car is 100% carbon-based. The energy in your home is usually not. It’s a mix of carbon-based and renewables. Also, your local coal plant is much more energy-efficient than your engine which probably hasn’t been tuned up in years.
