The short answer: A 2026 Tesla Model Y Long Range AWD costs about $12.97 per 100 miles to charge at home in Hawaii, and $42.43 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 47.18¢/kWh, up from 38.53¢/kWh in August 2025 and about 160% above the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $18.88 in a 30-mpg gas SUV at AAA’s Hawaii average of $5.664 a gallon (October 28, 2026), and about $24.12 at a public DC fast charger.

Checked on the Model Y: 27.50 kWh/100 mi × $0.4718/kWh = 12.9745, which rounds to $12.97 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $5.664 = 18.8797, or $18.88. The break-even electricity price is $18.88 ÷ 27.50 kWh = 68.65¢ per kWh.

Hawaii fast-charging price: Paren’s Q3 2026 report states a Hawaii average of $0.877 per kWh for public DC fast charging, against $0.540 nationally. This page uses the Hawaii figure.

Stations that bill energy delivered to the car charge less than the EPA wall figure. As a rough estimate (wall energy × 0.894, a Level 2 efficiency from Sears et al., 2014), the Model Y comes to about $21.56 per 100 miles at $0.877/kWh.
