This Small Island Nation Just Became the First to Run Entirely on Renewables

Sixty days is the milestone grid engineers have been watching. On Tuesday the utility confirmed the streak: every kilowatt-hour consumed on the island since mid-August came from wind, sun or stored sunshine.

The quiet hero of the system is a battery field the size of two football pitches. It smooths the evening gap between sunset and the night wind, a pattern engineers elsewhere long assumed would require fossil backup.

Officials have published the grid data hourly on a public dashboard, a transparency move they hope will pressure far larger economies to do the same arithmetic.

“A mix of solar, wind and a very large battery has kept the national grid at 100% clean energy for 60 straight days — and the receipts are public.”
