The world’s cumulative installed solar generation capacity has doubled between 2022 and 2024, to reach over 2,000TWh, which will be the driving force behind new renewable power capacity meeting global growth in electricity demand to 2030.
These are some of the key conclusions from Ember Climate’s latest report, the ‘2025 Global Electricity Review’, published today. The report is encouraging reading for the global renewable power sector, with the world adding 858TWh of new clean energy generation in 2024 – 49% more than in the previous record set in 2022, when the world added 577TWh – including 474TWh of new solar capacity.
This makes solar the largest source of new electricity generation for the third consecutive year, and the fastest-growing source of electricity generation for the 20th year in a row. The world added 29% more capacity in 2024 than in 2023, and met 40% of the global increase in electricity demand, more than any other single technology, as shown in the graph below.
