EV vs Gas Cost Per Mile in Wyoming
At Wyoming's average prices, a Tesla Model 3 RWD costs an estimated $0.036 a mile to charge at home and a 30 mpg gas car $0.103 a mile in fuel: $807.10 a year apart over 12,000 miles. Charging here costs about a third or less of gasoline per mile: 35%.

Wyoming has the lowest count of battery-electric vehicles in the country. The 2025 tally is 1,900 all-electric and 1,200 plug-in hybrid vehicles in a light-duty fleet of 584,800, an electric share of 0.3% where the US stands at 2.1%. Spread over households, that is 0.8 EVs for each hundred homes; nationally the figure is 4.6.
What charging exists tilts toward fast charging. Of 365 public ports, 201 are DC fast and 163 are Level 2, a fast share of 55% that compares with 30% across the US. Set against so small a fleet, each port has just 5.2 registered EVs to serve, the lowest ratio of any state (US: 21.7), and each fast port 9, beside 72 nationally. Low crowding is not the same as easy access. The whole state has 126 public charging sites, and the distance between them, which these counts leave out, is what decides a trip.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Wyoming
At 14.4¢/kWh, a Model 3 RWD (25 kWh per 100 miles, EPA) draws 25 kWh from the wall for every 100 miles (the EPA measures it at the wall), so each mile costs $0.036. A 30 mpg car at $3.10/gal spends $0.103 a mile. Over 12,000 miles: $432.90 for the EV, $1,240.00 for gasoline, a difference of $807.10 a year (fuel only). A gas car would need about 86 mpg to match the EV's cost per mile in Wyoming.
What the numbers say
What the numbers say in Wyoming
On fuel cost alone the EV does better in Wyoming than its scarcity would hint. Household electricity averages 14.4¢/kWh, the 10th-lowest rate and 21% below the US average of 18.2¢/kWh, gasoline $3.10/gal, 3% below the US average of $3.20/gal, and the example's yearly fuel difference ranks the 10th-highest among the states. Charged at home, the Tesla Model 3 RWD comes to $0.036 a mile, where the national rate would give $0.045.
The tie point is a long way off: 41.3¢/kWh for electricity, against the 14.4¢/kWh average. Wyoming drivers will spend some of that cushion on the road, since 55% of public ports are DC fast and fast stations tend to bill above home rates. Someone who plugs in at home and fast-charges only on trips pays the home rate on most miles; if public stations carry most of yours, enter a station's per-kilowatt-hour price in the field above.
Winter is the third factor. With 7,400 heating degree-days, the 6th-highest among the states and 64% more than the US average of 4,500, an EV here spends much of the year drawing more energy than the rated figure behind this estimate. The cold-weather range page estimates the range given up at a set temperature.
Vehicle size is the fourth. The Ford F-150 Lightning on the average home rate costs $0.069 a mile, compared with $0.036 for the sedan-class example, so weigh it against your own gas pickup's mpg rather than 30 mpg.
A time-of-use or EV plan, if your utility sells one, puts its off-peak price in place of 14.4¢/kWh. EV charging cost by model gives monthly figures for other vehicles, and the Wyoming heating page runs the same power price against natural gas.
Questions
FAQ
Is charging an EV cheaper than gas in Wyoming?
At Wyoming's average prices, yes for the page's example: $0.036 a mile for a Model 3 RWD at home against $0.103 for a 30 mpg car, $807.10 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 41.3¢/kWh, or against a gas car rated above 86 mpg. Both prices are editable above.
What about public fast charging in Wyoming?
Fast chargers usually charge more per kWh than a home rate. This page uses Wyoming's home average, 14.4¢/kWh. To see the cost per mile on the road, type the charger's price per kWh into the electricity rate field; the gas side stays at $3.10/gal.
How do time-of-use rates change this in Wyoming?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 14.4¢/kWh (7.2¢/kWh), the Model 3 RWD would cost $0.018 a mile instead of $0.036. Check your utility's tariff for the real overnight rate and type it in.
Can I count on fast chargers for long drives across Wyoming?
The state has 201 DC fast ports, the 45th-highest count among the states, spread over 126 public sites. Each fast port has 9 registered EVs to share it, where the national average is 72, so spacing matters more than waiting, and the counts don't measure spacing. Map your stops ahead, and plan around winter range in a state with 7,400 heating degree-days.
If I drive a pickup in Wyoming, does an electric one still save on fuel?
Match like with like. At 14.4¢/kWh, the Ford F-150 Lightning costs $0.069 per mile. A gas pickup's per-mile cost is the price of a gallon, $3.10/gal, divided by its mpg; any truck rated below 30 mpg lands above the $0.103 the page shows for its car. Put your truck's rating into the calculator to see the gap for your own pair.
