EV Charge 
A Tesla Model 3 owner in Illinois pays about $57 in electricity per 1,000 miles when charging at home, based on 19.32¢ per kWh, the EIA’s latest state average (August 2026). That’s $0.057 per mile and about $17.66 for a full charge.
Illinois ranks #18 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 $138 on fuel for those 1,000 miles at Illinois’s $4.14 a gallon, so home charging saves roughly $81 every 1,000 miles.
