Wind energy infrastructure doesn’t produce power if the air isn’t moving, and solar doesn’t generate power if the sun’s not out. But that doesn’t mean that either source of energy is "worthless" ...

In fact, the turbines were able to reach an efficiency of 53%, which is just shy of Betz's Law, a theorem that says no wind turbine would be able to convert more than about 59.3% of wind energy into ...

Look up in the sky, it's a bird, it's a plane, it's ... a 20,000 cubic-meter power-generating airship, floating 6,560 ft (2,000 meters) above the ground. Introducing the S2000 stratospheric airborne ...

As President Trump tries to strangle wind projects in the US, nine European countries have signed a deal to build a vast offshore wind farm in the North Sea, the epicenter of the continent’s oil and g ...

2025 was a difficult year for clean energy, with major U.S. tax rollbacks and weak European auctions leading to widespread cancellations of solar, wind, and storage projects. Policy adjustments are ...

The future of renewable energy might be in the sky. Researchers in China have reportedly tested a new, gravity-defying wind turbine system that they say could generate power from the airspace above ...

Rural Kansas counties see renewable energy as an economic lifeline, but local pushback is stalling wind and solar projects.
