Compare annual fuel cost of a gas car versus an electric vehicle.
Both cars are reduced to their per-mile energy cost, then scaled to a year of driving. The difference is the annual savings from switching. Electricity is usually far cheaper per mile than gasoline, but the gap depends heavily on your gas price, electricity rate and driving volume.
Gas vs Electric Savings
Gas annual = miles / MPG x gas price; EV annual = miles / (mi per kWh) x rate
