Key source for real-time electricity generation data

In 2004, it took the world an entire year to install one gigawatt of solar power. By 2025, that amount went online every single day—a pace that propelled global renewable capacity past 5,000 gigawatts by year-end. Science Magazine named this accelerating surge in renewable energy its 2025 Breakthrough of the Year, recognizing solar and wind eclipsing coal as the world's largest electricity source; yesterday, U.S. Energy Information Administration data confirmed renewables supplied a record 25.7% of U.S. electricity in 2025, generating 1,162 terawatt-hours—a 10% increase over 2024—with utility-scale solar up 34.5% and 53 gigawatts of new renewable capacity added.

Published the landmark H1 2025 analysis confirming renewables overtook coal

Renewables are now in the process of overtaking coal globally after drawing level in 2025, according to the International Energy Agency's February 2026 Electricity report. Solar and wind generation continues its exponential growth, with renewables and nuclear combined forecast to reach 50% of global electricity by 2030—up from 42% today. Solar photovoltaic alone is projected to add over 600 TWh annually through 2030, driving renewable generation growth at 8% per year. The transition is accelerating across regions: coal use declined in India and China due to slower demand growth and rapid renewable expansion, while coal remained broadly flat globally in 2025 after peaking in 2023. A historic milestone emerged in China in early February 2026, where wind and solar capacity officially exceeded coal capacity for the first time in history—with solar capacity alone projected to surpass coal by 2026.
