Brussels, 10 July 2025 – New analysis from global energy think tank Ember finds that solar was the EU’s largest single source of electricity in June 2025 for the first month ever, with a record 22.1% share.
At least 13 EU countries also had their highest ever month of solar generation in June, as new solar capacity installed in recent years paid off amid hot and sunny weather. The top record setters were the Netherlands (40.5%) and Greece (35.1%).
The record solar performance helped the EU power system to handle higher levels of demand resulting from heatwaves that gripped the continent towards the end of June.
Wind power also saw a strong start to summer, generating 16.6% and 15.8% of EU electricity in May and June respectively – the highest levels ever for those months. Good wind conditions were the main driver of this increase.
“Europe is becoming a solar powerhouse. Non-stop records are not just the result of sunny weather, but also from new solar being built every year,” said Chris Rosslowe, energy analyst at Ember.
