Clean Electricity Share by Country 2025

What this chart shows. The 20 countries that got the largest share of their electricity from clean sources in 2025, among the 78 countries in Ember's data that generated at least 10 TWh. Costa Rica, Ethiopia and Paraguay are shown at 100 per cent, followed by Norway at 99.0 per cent and Sweden at 98.8 per cent. Across the world clean sources supplied 42.6 per cent of electricity, up from 40.9 per cent in 2024.

How the data is collected. Ember counts as clean all renewable sources, hydro, wind, solar, bioenergy and other renewables, plus nuclear power. The share is clean generation divided by total generation in the same year, measured where the power is produced.

Background. 12 countries of this size reached at least 90 per cent. In 11 of the 20, hydropower supplied more than half of all generation; it made up 99.5 per cent of Paraguay's generation and 96.5 per cent of Ethiopia's; France, at 94.8 per cent, relies mainly on nuclear. Denmark had the largest rise among the 20, from 89.3 to 94.2 per cent.

Limits. Hydropower depends on rainfall, so these shares move with wet and dry years: Portugal's fell from 85.2 to 80.9 per cent, the largest drop in the chart. Ember has no 2025 figure for some countries, including Iceland, which is almost entirely powered by hydro and geothermal plants.
