Where the World’s Electricity Comes From, in One Chart
Share of world electricity generation by source, latest year, %
Plays the chart through its history, period by period.
Ember (CC BY 4.0) global electricity data. Each rectangle is a source, sized by its share of the year’s generation and coloured fossil, nuclear or renewable.
The world’s power supply in one picture. The fossil block shows how much still comes from coal and gas; the renewables block shows hydro, wind and solar together.
