Wind and solar power now make up a fifth of all of Utah’s electricity

Wind and solar power are rapidly expanding across the Mountain West, with some states now generating a significant share of their electricity from renewable sources.

That’s according to a new report from Climate Central, a nonpartisan research group.

Wind and solar now generate about half of New Mexico’s electricity, roughly 40% in Colorado and about a third in Nevada. In Wyoming, they account for around 30%, while Idaho gets about a quarter. In Arizona and Utah, wind and solar produce about 20% of electricity.

A big reason: falling costs.

Prices have dropped about 75% for solar and roughly 50% for wind over the past decade, helping make them some of the cheapest sources of new electricity, said Climate Central’s Kaitlyn Trudeau.

“These are really cheap sources of energy, and they’re abundant,” Trudeau said. “We’ve got them — we’ve got wind, we’ve got sun.”

Nationwide, wind and solar generated enough electricity last year to power more than 79 million homes, according to the report.

Despite headwinds, the U.S. clean energy transition advanced in 2025 with record levels of electricity from solar and wind. — A bar graph measuring U.S. solar and wind power in thousands of gigawatt hours from 2016 to 2025. Wind increased every year except 2023, where it dipped slightly, and overall went from a little over 200,000 gigawatt-hours to a little under 500,000. Solar increased every year and had a much larger growth, going from about 50,000 gigawatt-hours to nearly 400,000.

But demand for electricity is also rising, driven in part by energy-hungry data centers, the growth of artificial intelligence, and increasing heating and cooling use in homes and businesses.

“Data centers are becoming a really big deal, and they’re putting pressure on electricity systems and on everyday Americans,” Trudeau said.

That demand could put pressure on utilities to keep pace, even as policymakers and grid operators face constraints around transmission capacity and energy storage.

Those challenges, including policy uncertainty and limits on grid infrastructure, could shape how quickly renewable energy continues to grow in the Mountain West, Trudeau said.
