Costa Rica nears 99% renewable electricity (2025 figure confirmed)

Published · Researched 2026-09-22

What happened (dated facts)

Costa Rica generated 98.6% of its electricity from renewable sources in 2025, according to reporting by Explore Costa Rica (2026).
The mix is dominated by hydropower, with wind, geothermal, solar, and biomass contributing.
Costa Rica has run on near-100% renewable electricity for most of the past decade — one of the world's longest clean-grid streaks.
The figure is explicitly a 2025 outcome reported in 2026; no verified 2026 full-year figure exists yet (the year is incomplete).

A whole country running its grid on ~99% renewables, sustained over a decade, remains the global benchmark for clean electricity.

Positivity check: passes with caveat — the 98.6% is a 2025 figure, not 2026; the story is the sustained streak, honestly dated.

The underlying official source (Costa Rican grid operator/ICE data) was not directly reviewed.
Transport and heating decarbonization lag electricity; the figure covers electricity only.
