Renewable energy generation in the European Union climbed again in the third quarter of 2025, accounting for nearly half of all electricity produced across member states. New data shows that renewables supplied 49.3% of net electricity in Q3, up from 47.5% in the same period last year, a gain of roughly 4 percentage points that underscores the bloc’s ongoing energy transition.
The figures released by Eurostat signal steady progress toward cleaner power even as markets weigh supply challenges and policy debates. A majority of EU countries saw year-on-year increases in renewables’ share of electricity output, reflecting robust investment in clean sources and grid integration.
Denmark led the European Union in renewables penetration, generating 95.9% of its electricity from renewable sources in the third quarter of 2025. Austria and Estonia followed with 93.3% and 85.6%, respectively. On the other end of the spectrum, Malta, Czechia, and Slovakia recorded the lowest shares, each below 22%.
The share of electricity from renewables grew in 21 EU countries compared with Q3 2024. Estonia posted the largest jump, with a 20.6 percentage point rise, followed by Latvia’s 18.9-point increase and Austria’s 16.3-point gain. These strong gains stand in contrast to earlier quarters in 2025, such as Q1, when renewables briefly dipped due to weather-related fluctuations in wind and hydropower output.
Solar energy continued to dominate the renewable mix in Q3 2025, contributing roughly 38.3% of all renewable generation, followed by wind at 30.7% and hydropower at 23.3%. Smaller shares came from combustible renewable fuels and geothermal. These patterns echo broader seasonal trends where photovoltaic output typically rises during sunny months, reinforcing solar’s central role in decarbonizing the bloc’s power supply.
Energy analysts said the third-quarter figures reflect a mix of long-term policy direction and near-term operational improvements. Dr. Elena Marino, an energy policy researcher, explained that the increase points to a deeper structural shift in Europe’s power system. EU countries are combining wind, solar, and hydropower and building more resilient clean energy mixes despite ongoing grid and storage constraints.
She added that reaching close to 50 percent renewables over a single quarter is more than a symbolic marker, as it signals growing technical capacity and market readiness to absorb higher levels of clean electricity.
However, several challenges still remain. Industry observers point to lingering bottlenecks in permitting, grid upgrades, and storage capacity that could slow deeper penetration of renewables. Earlier reports have flagged permitting delays and cost pressures on solar and wind project rollouts, even as capacity additions continue to rise. Looking ahead, the third quarter’s performance sets a solid baseline for 2025 and offers a snapshot of how the EU’s electricity mix is evolving.
The proliferation of renewables in different markets allows other ancillary firms like Greenwave Technology Solutions, Inc. (NASDAQ: GWAV) to access the clean energy that they need to move forward with their own green production processes.
