Global Electricity Review 2025: Clean Power Surpasses 40%
Global Electricity Review 2025: Clean Power Surpasses 40%
The Global Electricity Review 2025, published by Ember, reveals significant progress in the global energy transition during 2024. For the first time since the 1940s, clean power sources — including renewables and nuclear — have surpassed 40% of worldwide electricity generation. This milestone highlights the accelerating adoption of solar, wind, and other low-carbon technologies amid rising global electricity demand.
For a comprehensive understanding of the previous year’s trends, refer to our Global Electricity Review for 2024.
Key Highlights from the 2025 Review
Clean Power Surpasses 40% of Global Electricity Generation
In 2024, renewables and nuclear collectively accounted for 40.9% of global electricity output, up from 39.4% in 2023. This jump was driven by an unprecedented 858 TWh increase in renewable energy, led by solar and wind. Notably, solar power generation has doubled in three years, contributing over 2,000 TWh worldwide.
