Cost per Mile
If an Electric Vehicle consumes 263 Wh/mi, and the cost of a kw/h is 20 pence, how much does it cost to drive 1 mile?
To find the cost of driving 1 mile:
Convert the consumption to kWh/mi: 263 Wh/mi = 0.263 kWh/mi
Multiply the consumption per mile by the cost per kWh: 0.263 kWh/mi × 20 pence/kWh
= 5.26 pence/mi
So, it costs 5.26 pence to drive 1 mile in that Electric Vehicle given the specified consumption and energy cost.
If the cost per litre of fuel is 150p, and a typical gasoline car has about 36 MPG, how much does it cost to drive one mile?
Convert the fuel efficiency from MPG to MPL (miles per litre): 36 miles/4.54609 litres = 7.92 miles/litre
Find out how much fuel is used for 1 mile: 1 mile/7.92 miles/litre = 0.1263 litres
Calculate the cost to drive one mile: 0.1263 litres × 150p/litre = 18.945 pence
As of August 2023, it’s almost four times cheaper to drive a mile in an electric vehicle than a gasoline vehicle.
Lets not forget the other benefits of electric vehicles, such as:
- cleaner air
- less noise pollution
- less maintenance
- cleaner over time as the electricity grid becomes greener
