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.

The U.S. already has about 3,000 data centers — and that number is expected to grow quickly in the coming years. A new report finds much of that growth is shifting away from cities and into rural areas, including in the Mountain West.

As data centers rapidly expand across the Mountain West, researchers say a key question is getting harder to answer: how much water are they actually using?

New funding is aimed at helping fossil fuel-dependent communities in the Mountain West navigate a changing energy economy, with one project focused on the Four Corners region.

Researchers at the University of Nevada, Reno, have received a $9 million grant from the U.S. Department of Energy to study an unlikely candidate for future fuels: cactus pear.

The power grid across Western states is under growing strain. Now, a new report argues the region’s governments and utilities need to work together to keep the lights on and costs down.

Federal land managers are reopening their environmental review of a massive transmission line proposed across Nevada, a move conservation groups say could reshape how energy infrastructure is approved on public lands across the West.

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 new report finds multi-day streaks of extreme heat are becoming stronger and lasting longer across the U.S., especially in Mountain West states. Experts warn that heatwaves are not only a health concern, but can strain energy resources.
