A new International Energy Agency review of 2025 finds that solar photovoltaics led global energy supply growth for the first time, while batteries expanded at a record pace and electricity demand rose faster than total

North American grid watchdog NERC is preparing a Level 3 essential actions alert after multiple large computational loads, including data centers, unexpectedly dropped 1,000 MW or more from the bulk power system in recen

Penn State researchers have directly observed corona discharges from treetops in nature, confirming a phenomenon suspected for decades.

Only 2.6 gigawatts of U.S. coal capacity retired in 2025, the lowest total in 15 years, after delayed closures, canceled retirement plans, and federal emergency orders kept more plants available.

The U.S. Energy Information Administration expects solar output to rise sharply this summer, with renewables taking a larger role in meeting seasonal peaks while coal generation continues its longer-term decline.

A report pointing to new U.S. research on high-temperature superconductors offers only limited detail, but it underscores continued interest in materials that could move electricity with essentially no loss.

The global gas turbine market is experiencing demand-driven supply shortages stretching lead times to five years or more and pushing costs to unprecedented levels, creating reliability risks for utilities that assumed turbines would remain readily available.

Edison Electric Institute reports investor-owned utilities are working to interconnect 39 gigawatts of new data center and manufacturing load — a grid challenge with no modern precedent.

Power flow control devices and advanced grid technologies are unlocking significant transmission capacity on existing infrastructure, reducing the need for costly new power line construction.
