Several countries, including Spain and Germany, received more than one-third of their electricity from solar in June; in Hungary, it supplied nearly 50%. Five years ago, solar delivered around 10% of the EU’s electricity even in the sunniest months. More solar has meant less coal and natural gas on the EU grid, which has helped slash planet-warming pollution. Carbon dioxide emissions from the EU electricity sector declined by nearly one-fifth between 2020 and 2025. Shortly after the U.S. and Israel initially attacked Iran, EU energy chief Dan Jørgensen urged the bloc to double down on clean energy.
