Curtailment is a power grid deliberately throwing away electricity it could have used — almost always wind or solar, almost always free at the point of generation. In the first half of 2026, China alone spilled an estimated 360 terawatt-hours of clean power, more than...

The United States has now built 100 gigawatts of solar modules over its history, and more than 70% of that total was assembled after the Inflation Reduction Act passed in late 2022. It is a genuine industrial turnaround. It is also a milestone measured at the one step...

Texas has built the largest grid-battery fleet in the United States — roughly 21 GW of operating capacity by mid-2026, against California’s 17 GW — and it did so with no storage mandate, no capacity market and no climate target. The lesson the rest of the...

Researchers at Nanjing University pushed a perovskite-organic tandem solar cell to a certified 26.88% efficiency — 27.35% before independent verification — a world record for the design, published in Joule in September 2026. It is a real milestone. It is also the...

A land equivalent ratio, or LER, measures whether doing two things on one piece of land beats doing each on its own. In agrivoltaics — solar panels raised over a working field — an LER of 1.6 means you would need 1.6 hectares of single-use land, one growing the crop...

Almost every transformer on the power grid — the humming boxes that step voltage up at a power plant and back down on your street — is built around a core of grain-oriented electrical steel. In the United States, exactly one mill still makes it. That single dependency...
