In the first five months of 2025, coal power has fallen in China compared to 2024. Solar power is up 120 TWh, meeting 86% of the increase in electricity demand ☀️⚡️ Wind also up substantially

NEW | Solar power was the EU’s biggest power source in June 2025 ☀️ For the first time, solar ranked first among all power sources, producing 22.1% of the EU’s power ahead of nuclear at 21.8%. Coal power fell to a record low 6.1% in sixth place.

NEW | Solar is now California’s #1 electricity source ☀️ Over the past 12 months (to April), solar generated more electricity than any other source in California — surpassing gas for the first time in history. Rapid solar + battery deployment will keep this trend going 🔋⚡️

LATEST DATA | Strong solar additions and favourable hydro conditions in China pushed coal power down 5.4% in September compared to 2024 🇨🇳⚡️ Year-to-date, coal power remains down 1.4%.

Another new record for batteries in California 🔋⚡️ Batteries met a record high 37.2% of load at 6:25pm yesterday, Oct 12. The share of load remained at >30% for two whole hours from 5:50 to 7:50 during peak demand and discharged late into the night, reducing gas and imports.

NEW | EU solar generation has already exceeded its 2024 total as of September ☀️🇪🇺 Solar is by far the fastest growing source of electricity in the EU, up 20% year-on-year.

NEW DATA | For the first time ever, wind and solar produced more than 50% of the UK's electricity ☀️🍃🇬🇧 🏆 In September, wind and solar generation reached a share of 50.4% Both wind and solar generation also reached new absolute output records for the month of September: Wind: 7.7 TWh Solar: 1.7 TWh

NEW @ember-energy.org report out today | Renewables now produce more electricity than coal worldwide ⚡️ Renewables produced 5,072 TWh (34.4% share) in the first half of 2025 overtaking coal for the first time which stood at 4,896 TWh (33.1%.)

More than 5% isn't possible...more than 10% isn't possible... Solar was already at 8.8% of GLOBAL electricity generation in the first half of 2025, more than doubling since 2021 (3.8%). ☀️ I guess 30% is the new limit?? 🇭🇺Hungary: 29.7% 🇬🇷Greece: 26.3% 🇳🇱Netherlands: 25.7%

NEW | Electricity generation from fossil fuels fell in China and India in the first half of 2025 🔥📉 This marks a reversal from previous trends. Simultaneously, there was a small uptick in the US and in the EU. A thread 🧵

NEW DATA | China's exports of clean technologies exceeded 20 billion USD for the first time in August📈 We just published a new @ember-energy.org data tool to track exports of EVs, batteries, gridtech etc. on top of our existing tracking of solar exports. 🧵

It's astonishing how wide the battery curve has gotten in California. Last Tuesday, batteries consistently supplied more than 20% of demand for 4 hours from 6pm to 10pm. Price signals are working well.

NEW DATA | US solar power surpasses 2024 full year output in September 🇺🇸☀️ With three months left in 2025, solar generation reached 310 TWh, already surpassing the 2024 total of 302 TWh. Solar generation is up 30% in 2025 so far.
