EV Charge 
At Maryland’s average home electricity price of 21.40¢ per kWh, a Tesla Model 3 costs roughly $63 to drive 1,000 miles on home charging ($0.063 a mile). Filling the battery from zero costs around $19.56.
Maryland ranks #15 of 51 for electricity prices (1 = most expensive), so this is above 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 Maryland’s $4.33 a gallon, so home charging saves roughly $81 every 1,000 miles.
