Where Wyoming Gets Its Electricity
Net generation by source · 12-month average, July 2025 – June 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 10.8% | 4,789 GWh |
| Coal | 53.1% | 23,485 GWh |
| Nuclear | 0.0% | 0 GWh |
| Wind | 31.1% | 13,731 GWh |
| Solar | 1.1% | 490 GWh |
| Hydro | 2.8% | 1,247 GWh |
| Other | 1.1% | 469 GWh |
44.2 TWh generated over the 12 months to June 2026. Shares are of net generation within Wyoming, which is not the same as what the state consumes — power crosses state lines.
Counting rooftop solar
EIA reports small-scale solar — mostly rooftop panels on homes and businesses — separately, and leaves it out of the state generation total that the mix above is a share of. Wyoming generated 44 GWh that way. Counting it on both sides of the ratio takes solar from 1.1% to 1.2%.
How the mix has shifted since 2001
| Source | 2001 | 2025 | Change |
|---|---|---|---|
| Natural gas | 1.3% | 9.9% | +8.6 pts |
| Coal | 95.6% | 58.5% | −37.1 pts |
| Nuclear | 0.0% | 0.0% | — |
| Wind | 0.8% | 27.1% | +26.3 pts |
| Solar | 0.0% | 1.1% | +1.1 pts |
| Hydro | 2.0% | 2.1% | +0.2 pts |
| Other | 0.3% | 1.3% | +0.9 pts |
Compared with the U.S. and nearby states
Wyoming's generation mix in context
Coal supplies 54.1% of Wyoming's electricity generation, the largest share by far. Wind ranks second at 30.4%, giving the state a combined renewables share of 34.2%, which is carbon-free as well. Gas contributes 10.6%, while hydro, solar, and other sources together make up the remainder. Utility-scale solar alone accounts for 1.1% of generation; counting rooftop solar raises that to 1.2%.
The renewable share has grown dramatically since 2001, when it stood at 2.8%. Wind generation climbed from 0.8% in 2001 to 27.1% in 2025, the dominant force behind this shift. Coal fell steeply over the same span, from 95.6% to 58.5%. Gas rose from 1.3% to 9.9%, and solar emerged from nothing to 1.1% by 2025.
Wyoming's renewable share ranks 17th among the 51 states and DC, and its solar generation ranks 42nd. Both shares exceed the national mix: renewables account for 24.9% nationwide compared to 34.2% here, and coal supplies only 15.8% nationally against 54.1% in Wyoming. Most neighbouring states generate higher renewable shares; only Nebraska and Utah fall below Wyoming's, with renewable shares of 32.2% and 22.6% respectively.

How this is measured
Figures are net generation reported to the U.S. Energy Information Administration for all sectors — utilities, independent power producers, and industrial and commercial plants that generate their own power. Shares are of the 12 months to June 2026, rather than a single month, because generation is strongly seasonal: solar peaks in summer and hydro with the spring melt, so one month says more about the weather than about the grid.
“Other” is the reported total minus the six named sources, so the shares add to exactly 100%. It holds geothermal, biomass, petroleum, other gases, and pumped storage — the last of which consumes more electricity than it returns, and so can be negative. Geothermal and biomass are renewable, which is why the renewable share above is slightly larger than wind, solar and hydro added together.
This is generation, not consumption. Electricity crosses state lines freely, so a state can generate more than it uses or rely on imports for a large part of its supply; neither shows up here.
