China leads wave of clean power wastage as grids globally hit limits

China turned away about 360 TWh of wind and solar in Jan–Jun 2026 — enough to power Mexico for a year — as grid limits and coal contracts force widespread curtailment.
Curtailment is rising globally too: Australia, Japan and India all saw big jumps, showing networks aren’t keeping pace with rapid renewables growth.
Investors and developers are shifting toward solar-plus-storage and bigger battery builds to cut waste and curb a renewed reliance on coal.
