EV Charge 
At Hawaii’s average home electricity price of 47.18¢ per kWh, a Tesla Model 3 costs roughly $140 to drive 1,000 miles on home charging ($0.140 a mile). Filling the battery from zero costs around $43.13.
Hawaii ranks #1 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 Hawaii’s $4.33 a gallon, so home charging saves roughly $5 every 1,000 miles.
