Where Oklahoma Gets Its Electricity
Net generation by source · 12-month average, September 2025 – August 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 43.1% | 41,147 GWh |
| Coal | 7.5% | 7,118 GWh |
| Nuclear | 0.0% | 0 GWh |
| Wind | 45.4% | 43,370 GWh |
| Solar | 1.8% | 1,703 GWh |
| Hydro | 2.0% | 1,867 GWh |
| Other | 0.3% | 280 GWh |
95.5 TWh generated over the 12 months to August 2026. Shares are of net generation within Oklahoma, 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. Oklahoma generated 295 GWh that way. Counting it on both sides of the ratio takes solar from 1.8% to 2.1%.
How the mix has shifted since 2001

| Natural gas | 32.5% | 44.7% | +12.3 pts |
| Coal | 62.7% | 10.4% | −52.3 pts |
| Nuclear | 0.0% | 0.0% | — |
| Wind | 0.0% | 41.8% | +41.8 pts |
| Solar | 0.0% | 0.8% | +0.8 pts |

Compared with the U.S. and nearby states
Oklahoma's generation mix in context
Wind dominates Oklahoma's electricity generation, supplying 45.4% of the total in the twelve months since September 2025. Gas and wind together account for most of the state's output, with gas contributing 43.1%. Renewables as a whole made up 49.5% of generation, giving Oklahoma a carbon-free share of 49.5%. Solar accounted for 1.8% of generation at utility scale, or 2.1% when rooftop solar is included.
Oklahoma's renewable share ranks 13th of the 50 states and DC, and its solar share ranks 39th. Compared with the nation, Oklahoma generates far more from wind—45.4% against 10.8%—and substantially more from renewables overall, which made up 49.5% of the state's mix against 25.4% nationally. Gas supplies a slightly larger share in Oklahoma than across the country. Among the six neighbouring states, New Mexico and Kansas have higher renewable shares, while Colorado, Texas, Missouri and Arkansas have lower ones.
The shift across the years since 2001 has been dramatic. Renewable generation grew from 4.7% in 2001 to 44.9% in 2025, with wind rising from nothing to 41.8%. Coal plummeted from 62.7% in 2001 to 10.4% in 2025. Gas climbed from 32.5% to 44.7%, and hydro fell from 4.2% to 1.9%..

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 August 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.
