Tracking the world's electricity generation across 30 countries and 8 energy sources — from the coal-dominated past to the renewable future. Data from the IEA, Ember, and the Energy Institute.
Watch how the world's electricity sources have shifted from 2000 to 2024. Press play or drag the slider.
Grams of CO₂ emitted per kilowatt-hour of electricity generated. Lower is cleaner. Color ranges from green (<100) to deep red (>700).
Key metrics from the world's energy transition.
Energy mix snapshots for the world's top electricity producers.
Solar PV added ~480 TWh in 2024 alone — more than any single energy source has ever added in a year. In the first half of 2025, solar grew another 31%, its fastest absolute growth on record. Solar now generates 7% of the world's electricity, up from virtually zero in 2010. [1][2]
Despite record renewable growth, coal still generates 35% of global electricity — nearly double its nearest rival (gas). Coal generation actually hit an all-time high in 2024 due to rising demand in Asia, even as it collapses in the EU (down to 11%). The transition is real but uneven. [3][4]
Brazil generates 87% of its electricity from renewables (mostly hydro), while France achieves 92% low-carbon power through nuclear (67%) plus renewables. Both countries maintain carbon intensities under 100 gCO₂/kWh — less than a fifth of the global average. [5][6]
