Solar leads EU electricity generation as renewables hit 54%

More than half of the European Union’s (EU) electricity came from renewables in the second quarter of 2025, and solar is leading from the front.

According to new data from Eurostat, renewable energy sources generated 54% of the EU’s net electricity in Q2 2025, up from 52.7% year-over-year. The growth came mainly from solar, which produced 122,317 gigawatt-hours (GWh) – nearly 20% of the total electricity generation mix.

June 2025 was a milestone month: Solar became the EU’s single largest electricity source for the first time ever. It supplied 22% of all power that month, edging out nuclear (21.6%), wind (15.8%), hydro (14.1%), and natural gas (13.8%).

Some countries are already nearly 100% renewable. Denmark led with an impressive 94.7% share of renewables in net electricity generated, followed by Latvia (93.4%), Austria (91.8%), Croatia (89.5%), and Portugal (85.6%). At the other end of the spectrum, Slovakia (19.9%), Malta (21.2%), and the Czech Republic (22.1%) lagged behind.
