The U.S. is building more solar farms than ever. But as projects expand, they're also raising questions about where they belong. A new industry analysis suggests one of the biggest concerns — that solar is consuming too much prime farmland — may be overstated, especially in the American West.

For the first time on record, solar power generated more electricity than coal in the United States during a full calendar month — a milestone that underscores how quickly the nation's power system is changing.

Utilities across the West are launching a new regional energy market designed to help them buy and share power a full day before it’s needed — an effort supporters say could lower costs, improve reliability and make it easier to move renewable energy across state lines.

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

States across the Mountain West added record amounts of wind and solar power in 2024. Now, a new industry report shows the region is also becoming a national leader in battery storage.

As large solar projects become more common across the Mountain West, questions remain about their environmental footprint, especially in fragile desert ecosystems. New research from Nevada suggests that with careful planning, renewable energy development and rare native plants may be able to coexist.

A new report from the Solar Energy Industries Association warns that more than 500 planned solar projects nationwide could be delayed or canceled as the Trump administration pivots back toward fossil fuels.

California just took a major step toward reshaping how electricity moves across the Western U.S. It’s a change that could transform the region’s power grid and boost clean energy.

A proposal to build one of the largest solar projects in the U.S. has been abruptly halted by the Trump administration — a move critics say undermines the nation’s renewable energy transition.

President Donald Trump’s “One Big, Beautiful Bill Act” phases out tax credits for clean energy projects, slowing the addition of new power to the grid. Experts predict it could drive up energy costs, especially in parts of the Mountain West.
