The European Union generated more than half of its electricity from renewable sources in the second quarter of 2025, with a share of 54%, an increase from 52.7% the previous year, according to data released by Eurostat on Monday.
This rise was primarily driven by solar energy, which produced 122,317 gigawatt-hours, accounting for 19.9% of total electricity generation during this period.
In June 2025, solar energy became the leading source of electricity in the European Union for the first time, with a share of 22%, surpassing nuclear energy (21.6%), wind energy (15.8%), hydropower (14.1%), and natural gas (13.8%).
At the national level, Denmark topped the list, with 94.7% of its electricity generated from renewable sources, followed by Latvia (93.4%), Austria (91.8%), Croatia (89.5%), and Portugal (85.6%). In contrast, Slovakia (19.9%), Malta (21.2%), and the Czech Republic (22.1%) reported the lowest percentages.
In 15 EU countries, the share of renewable energies increased compared to the second quarter of 2024, with Luxembourg (+13.5 percentage points) and Belgium (+9.1 percentage points) showing the highest increases, thanks to a boom in solar energy.
According to Eurostat, 36.8% of electricity generated from renewables came from solar energy, 29.5% from wind energy, 26% from hydropower, 7.3% from biofuels, and 0.4% from geothermal energy.
