From July 2025 through June 2026, fossil fuels supplied about 58% of Missouri’s electricity consumption, with coal alone accounting for almost 47% and gas about 11%. Low-carbon sources supplied roughly a quarter: nuclear contributed 11%, wind 8%, solar 4%, and hydropower just over 1%. Net imports covered another 18%; their generation mix is not specified, so they cannot be classified here as either clean or fossil electricity. Missouri therefore remains heavily dependent on fossil electricity, with considerable room to expand clean generation and reduce the climate and air-pollution impacts of coal and gas.

Is Electricity Growing in Missouri?

Electricity consumption in Missouri is growing, although only slightly: the latest 2026 figure reached about 14,200 kWh per person, exceeding the previous record set in 2025 by 63 kWh per person, or roughly 0.4%. Low-carbon electricity generation grew much more strongly, reaching about 3,500 kWh per person. That is 354 kWh per person above the previous record from 2024—an increase of about 11%. This new clean-electricity record is encouraging, and sustained growth will help meet future demand from electrification and AI.

Suggestions

Missouri should expand its existing nuclear generation through capacity increases and consider additional reactors, while accelerating solar and wind development. Nearby regions offer useful examples: the US state of Illinois generates almost half its electricity from nuclear, while the US state of Iowa gets 57% from wind and the US state of Kansas gets 49%. These neighboring successes demonstrate the substantial contributions nuclear and wind can make to a regional electricity system. For solar, Missouri can learn from the US state of Nevada, where solar supplies 35% of generation, and the US state of California, where it supplies 31%, while adapting their deployment experience to local conditions. Together, more nuclear, solar, and wind would strengthen Missouri’s clean electricity supply.

History

The available history, covering 2024 through 2026, shows uneven but ultimately encouraging progress in low-carbon electricity generation. In 2024, nuclear generation increased by 1.3 TWh and hydropower by 0.4 TWh, while wind and biofuels were unchanged. Clean-electricity momentum weakened in 2025, before a strong recovery in 2026 brought an additional 2.7 TWh of nuclear generation and 0.6 TWh of wind generation. Hydropower and biofuels were unchanged in both 2025 and 2026. Across the three years, nuclear generation recorded a net gain of 0.6 TWh, wind 0.3 TWh, and hydropower 0.4 TWh. The priority now is to turn this recent recovery into sustained clean-electricity growth.
