From September 2025 through August 2026, fossil fuels accounted for about 65% of Wyoming’s electricity consumption, while low-carbon sources supplied about 35%. Coal dominated at just over half of the total, followed by gas at about 13%. Wind supplied almost a third of electricity and accounted for most of the clean electricity share. Hydropower contributed roughly 2% and solar about 1%, leaving considerable room to expand low-carbon electricity and reduce reliance on fossil fuels, which contribute to climate change and air pollution.

Is Electricity Growing in Wyoming?

Wyoming’s latest electricity figures show a mixed picture: total consumption declined, but low-carbon generation grew. Electricity consumption in 2026 was about 74,700 kWh per person, down roughly 2,600 kWh, or 3%, from the 2025 record of about 77,300 kWh per person. In contrast, low-carbon electricity generation reached a new high of about 26,100 kWh per person, exceeding the previous record by roughly 2,200 kWh, or 9%. That clean electricity growth is encouraging, although the decline in overall consumption warrants attention as electrification and AI create opportunities for greater electricity demand.

Suggestions

Wyoming can build on its strong wind industry while expanding solar and developing nuclear electricity generation. Nearby Great Plains examples show the potential for more wind: the US states of South Dakota and Iowa generate about 58% and 57% of their electricity from wind, respectively, while Kansas reaches about 49%. For solar, Wyoming can learn from the western US states of Nevada and Utah, where solar supplies about 33% and 22% of electricity generation. Nuclear would add another substantial source of low-carbon electricity: the US state of Nebraska generates about 16% of its electricity from nuclear, while Arizona reaches 25%. Drawing on these regions’ experience with project development, transmission, and workforce training could help Wyoming grow a more diverse clean electricity supply.

History

From 2024 through 2026, Wyoming’s low-carbon electricity growth was driven overwhelmingly by wind. Wind generation increased by 0.4 TWh in 2024, surged by 3.7 TWh in 2025, and added another 1.3 TWh in 2026—a combined gain of 5.4 TWh. Hydropower followed a less encouraging path: a 0.1 TWh increase in 2024 was followed by declines of 0.2 TWh in 2025 and 0.1 TWh in 2026. Overall, strong wind expansion more than offset those hydropower declines, demonstrating the value of sustained investment in additional low-carbon electricity generation.
