EV Charge 
At Tennessee’s average home electricity price of 13.42¢ per kWh, a Tesla Model 3 costs roughly $40 to drive 1,000 miles on home charging ($0.040 a mile). Filling the battery from zero costs around $12.27.
Tennessee ranks #46 of 51 for electricity prices (1 = most expensive), so this is below the U.S. average of $54 per 1,000 miles for the same car. A 30-mpg gas car would spend about $144 on fuel for those 1,000 miles at Tennessee’s $4.33 a gallon, so home charging saves roughly $105 every 1,000 miles.
