Where Missouri Gets Its Electricity
Net generation by source · 12-month average, September 2025 – August 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 13.5% | 9,868 GWh |
| Coal | 56.4% | 41,150 GWh |
| Nuclear | 13.8% | 10,084 GWh |
| Wind | 9.8% | 7,117 GWh |
| Solar | 4.2% | 3,096 GWh |
| Hydro | 1.3% | 982 GWh |
| Other | 1.0% | 695 GWh |
73 TWh generated over the 12 months to August 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
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 859 GWh that way. Counting it on both sides of the ratio takes solar from 4.2% to 5.4%.
How the mix has shifted since 2001
| Source | 2001 | 2025 | Change |

| Natural gas | 4.9% | 13.1% | +8.2 pts |
| Coal | 82.7% | 63.7% | −18.9 pts |
| Nuclear | 10.5% | 9.9% | −0.7 pts |
| Wind | 0.0% | 9.0% | +9.0 pts |
| Solar | 0.0% | 2.2% | +2.2 pts |

Compared with the U.S. and nearby states
Missouri's generation mix in context
Coal supplies 56.4% of Missouri's electricity generation in the trailing twelve months since September 2025, making it by far the largest source. Nuclear provides 13.8% and gas 13.5%, together with coal accounting for more than four-fifths of the state's mix. Wind generates 9.8%, while solar contributes 4.2% when counted at utility scale alone, or 5.4% when rooftop solar is included. Hydro and other sources make up the remainder.
Missouri's renewable share stands at 15.5%, placing it 29th of the 50 states and DC. Carbon-free generation, which includes nuclear, reaches 29.3%. Both figures lag the national averages: renewables supply 25.4% nationwide and carbon-free sources 43.0%. Compared with the nation, Missouri generates far more coal—41 percentage points higher—and far less gas, at 27.4 points below the national share.
Since 2001, Missouri's generation mix has shifted markedly. Coal has declined from 82.7% in 2001 to 63.7% in 2025, losing 19 percentage points. Wind has grown from nothing to 9.0%, while solar has risen from zero to 2.2%. Gas has expanded from 4.9% to 13.1%, and renewables as a whole have increased from 1.4% to 12.8%. Among Missouri's eight bordering states, five generate a higher share from renewables: Iowa, Kansas, Oklahoma, Nebraska, and Illinois. Three—Arkansas, Tennessee, and Kentucky—rely less on renewables than Missouri does.

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.
