Missouri electricity generation by source, June 2025 – May 2026
Source	Share	Generation
Natural gas	13.6%	9,796 GWh
Coal	58.4%	42,246 GWh
Nuclear	12.4%	8,993 GWh
Wind	9.7%	7,036 GWh
Solar	3.5%	2,526 GWh
Hydro	1.3%	968 GWh
Other	1.0%	729 GWh

72.3 TWh generated over the 12 months to May 2026. Shares are of net generation within Missouri, which is not the same as what the state consumes — power crosses state lines.

Counting rooftop solar

Utility-scale solar

3.5%

Including rooftop

4.6%

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. Missouri generated 831 GWh that way. Counting it on both sides of the ratio takes solar from 3.5% to 4.6%.

How the mix has shifted since 2016

Missouri's generation mix in context

Coal dominates Missouri's electricity generation, supplying 58.4% of the 72.3 TWh generated between June 2025 and May 2026. This is far higher than the national average, where coal accounts for only 15.8% of generation and natural gas is the largest source. Nuclear provides 12.4% of Missouri's generation, while wind contributes 9.7%. Solar generated 3.5% when measured at utility scale alone, or 4.6% when rooftop solar is included. Together, renewables—including wind, solar, hydro and other renewable sources—make up 14.7% of the state's generation, placing Missouri 30th among 51 states and DC. Carbon-free sources, combining renewables with nuclear, account for 27.1% of the mix.

Over the decade from 2016 to 2025, Missouri's generation portfolio has shifted significantly. Renewable generation grew from 3.3% in 2016 to 12.8% in 2025, driven primarily by wind power, which expanded from 1.4% to 9.0%. Solar emerged from nothing to 2.2% of the mix in 2025. Coal's dominance has weakened, declining from 76.7% to 63.7%. Natural gas rose from 7.7% to 13.1%, while nuclear fell slightly from 12.0% to 9.9%.

Missouri's renewable share lags most neighbouring states. Five of its eight bordering states have higher renewable shares: Iowa at 61.5%, Kansas at 50.1%, Oklahoma at 48.3%, Nebraska at 32.2%, and Illinois at 17.4%. Arkansas and Tennessee have slightly lower renewable shares at 13.8% and 12.5% respectively, while Kentucky trails at 8.6%. Nationally, renewables account for 24.9% of generation, 10.2 percentage points above Missouri's current share.

Frequently asked questions

›What percentage of Missouri's electricity comes from renewable energy?

14.7% of the electricity generated in Missouri comes from renewable sources — wind, solar, hydro, geothermal and biomass — over the 12 months to May 2026. That compares with 24.9% nationally. Counting nuclear as well, 27.1% of Missouri's generation is carbon-free.

›What percentage of Missouri's power comes from solar?

Utility-scale solar farms supply 3.5% of Missouri's electricity generation. Adding small-scale rooftop solar, which EIA reports separately and leaves out of the state total, takes it to 4.6%. Nationally, utility-scale solar is 7.2%.

›Where does Missouri get most of its electricity?

Coal is the largest single source of electricity generated in Missouri, at 58.4% of the total. The rest breaks down as natural gas 13.6%, nuclear 12.4%, wind 9.7%, solar 3.5%, hydro 1.3%, other 1.0%.

›Does Missouri still burn coal for electricity?

Yes. Coal supplies 58.4% of Missouri's electricity generation, compared with 15.8% nationally. In 2016 it was 76.7%, so the share has fallen since.

›Is Missouri getting greener?

Renewables have gone from 3.3% of Missouri's generation in 2016 to 12.8% in 2025, a rise of 9.5 percentage points. Over the same decade coal went from 76.7% to 63.7% and natural gas from 7.7% to 13.1%.

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 May 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.
