Global Electricity Generation by Fuel Source
In 2025, global electricity generation reached 31,734 TWh, split between 57.4% fossil fuels and 42.6% low-carbon sources (nuclear + renewables). Inspect each generation source below for country-by-country rankings and 25-year trajectories.
Coal Electricity Generation
Coal remains the single largest source of global electricity generation by volume, though its share varies dramatically between fast-growing Asian industrial grids and rapidly decarbonizing OECD power systems.
Natural Gas Electricity Generation
Natural gas is the primary dispatchable baseload and peaking fuel in North America, the Middle East, and Eurasia, providing roughly 22% of world electricity.
Nuclear Power Generation
Zero-emission nuclear fission provides firm 24/7 baseload electricity across 30+ major economies, led by the United States, China, France, Russia, and South Korea.
Hydroelectric Power Generation
Hydroelectric dams remain the largest dispatchable renewable electricity source worldwide, anchoring the grids of China, Brazil, Canada, Norway, and the Pacific Northwest.
Wind Electricity Generation
Wind power has scaled from a niche European technology in 2000 into a multi-thousand-terawatt-hour source on the global electricity grid.
Solar Electricity Generation
Solar photovoltaics is the fastest-growing electricity generation technology in history, led by exponential utility-scale and distributed buildouts in China, the United States, India, and Europe.
Bioenergy & Biomass Power Generation
Bioenergy and waste-to-energy plants provide dispatchable renewable electricity and industrial cogeneration across Europe, Brazil, China, and North America.
Low-Carbon & Clean Electricity Generation
Combined low-carbon generation (nuclear fission plus all renewable sources) measures how much of a nation's electricity supply operates without direct fossil-fuel combustion.
