The world generated 31,820 TWh of electricity in 2025, up 3.1% on 2024. Low carbon sources (nuclear and renewables) supplied 42.3% of world electricity in 2025, up 1.5 points on 2024. Power sector emissions were 14,653 MtCO2 in 2025, up 0.6% on 2024. Each year below has its own review: the world totals against the year before, the mix by fuel, the countries that moved most in solar, wind, coal, carbon intensity and low carbon share, and the milestones the data shows. Everything is Ember's annual statistics, and each page says which countries it covers.
