Electric Vehicle Efficiencies

With just more than thirty thousand miles on our electric vehicle (EV), here are some figures and comparisons with a similar gasoline-powered (ICE) vehicle.

Average annual usage

According to the U.S. Department of Transportation’s Federal Highway Administration, the average person drives around 13,500 miles every year. With that in mind, the average person would reduce their annual operating costs would be around $430 instead of $830 (plus maintenance) (based on average fuel mileage[1]).

There would also be a more than 50% reduction in CO2 emissions.
