New figures show that solar and wind together supplied more than a third of the world's electricity during the last quarter, a record share. Analysts attribute the growth to falling equipment costs and faster grid approvals.
China, the United States, and the European Union added the most capacity. Energy storage projects also expanded rapidly, helping to smooth the intermittent output of wind and solar farms.
Experts caution that grid upgrades and long-distance transmission lines must keep pace to fully use the new capacity. Still, they describe the milestone as a clear signal that the energy transition is accelerating.
