EV Charge 
Charging a Tesla Model Y at home in Hawaii costs about $130 per 1,000 miles, or $0.130 per mile, at the state’s average residential rate of 47.18¢ per kWh (August 2026). A full charge from empty runs about $42.42.
Hawaii ranks #1 of 51 for electricity prices (1 = most expensive), so this is above the U.S. average of $50 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 $15 every 1,000 miles.
