Brazil Hydropower Share of Electricity by Year 2010-2025
Percentage of Brazil's electricity generated by hydropower in each year since 2010, as published by Ember. Each bar is one calendar year.
✨ AI Insight
Brazil ran on 78.19% hydropower in 2010 and 51.78% in 2025 - a fall of over 26 points, but not because it built fewer dams. Hydro output depends on rainfall and reservoir levels, which is why the series swings: 55.27% in 2021, back up to 63.07% in 2022, then down again. Meanwhile wind and solar have taken a growing slice of a growing grid, so hydro's share falls even in wet years. The 2025 figure is the lowest in the series, and the first time hydro has supplied barely half of Brazilian electricity.
