By Michael P. Tremoglie NEW YORK ( MainStreet) -- The U.S. Department of Energy (DOE) announced last month the launching of the "eGallon" - a tool that will compare the costs of fueling electric vehicles (EVs) to fueling gasoline-powered ones. According to the report, the national average eGallon price is about $1.14. This means that an EV can travel as far on $1.14 worth of electricity as a conventional vehicle on a gallon of gasoline. The tool also does state by state comparisons as well. So while everyone can currently calculate how much it costs to go to work with a conventional vehicle - now EV drivers will be able to calculate their costs.
