The short answer: A 2026 Tesla Model Y Long Range AWD costs about $3.97 per 100 miles to charge at home in Wyoming, and $12.98 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 14.43¢/kWh, up from 14.33¢/kWh in August 2025 and about 21% below the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $14.73 in a 30-mpg gas SUV at AAA’s Wyoming average of $4.420 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.

| 2026 Tesla Model Y Long Range AWD, charged at home | 14.43¢/kWh × 27.50 kWh | $3.97 | $476 | EPA · EIA |
| 2026 Tesla Model Y Long Range AWD, public DC fast | $0.540/kWh × 27.50 kWh | $14.85 | $1,782 | Paren, U.S. average |
| 2026 Toyota RAV4 (2.5 L hybrid, 2WD) | $4.420/gal ÷ 43 mpg | $10.28 | $1,234 | EPA · AAA |

- Home charging vs the gas SUV: about $1,292 a year less at 12,000 miles. Home charging stays cheaper until electricity reaches about 53.58¢/kWh, 3.7× the state average.
- Home charging vs the hybrid: home charging is about $757 a year cheaper. The break-even against the hybrid is 37.38¢/kWh.
- Public fast charging vs gas: relying on DC fast charging costs more than the gas SUV at these prices ($14.85 vs $14.73 per 100 miles).
Checked on the Model Y: 27.50 kWh/100 mi × $0.1443/kWh = 3.9682, which rounds to $3.97 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $4.420 = 14.7337, or $14.73. The break-even electricity price is $14.73 ÷ 27.50 kWh = 53.58¢ per kWh.

Public charging in Wyoming
The AFDC counted 365 public charging ports at 126 locations in Wyoming on October 28, 2026: 163 Level 2 and 201 DC fast, plus 1 Level 1. AFDC also counts about 1,900 battery-electric vehicles registered in Wyoming through 2025 (0.3% of light-duty registrations). That is about 5.2 EVs per public port, against 21.7 nationally, the fewest EVs per port among the 50 states and the District.
Paren’s Q3 2026 report has no Wyoming figure, so fast-charging math here uses its U.S. average of $0.540 per kWh.
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 $13.28 per 100 miles at $0.540/kWh.
