Despite record renewable deployment, fossil fuels still generated the majority of the world’s electricity in 2025.
This visualization breaks down the global electricity mix by source, showing that coal alone still accounts for roughly one-third of worldwide power generation. Natural gas remains the second-largest source, highlighting how deeply fossil fuels remain embedded in the global energy system.
At the same time, solar and wind continue expanding rapidly and now rival nuclear power in total electricity generation. The data for this visualization comes from Ember, as of 2025.
