Overview

• Solar energy reached 22 percent of the EU’s electricity mix in June 2025, surpassing nuclear power for the first time and driving monthly generation records in 13 member states.
• Germany commissioned 409 onshore wind turbines (2.2 gigawatts) in the first half of 2025, its strongest six-month build-out since 2017 and lifting renewables to over 54 percent of consumption despite a seasonal wind slump.
• North Rhine-Westphalia led national gains with 101 new turbines adding 525 megawatts, while Brandenburg commissioned 45 units totaling nearly 240 megawatts—a 73 percent increase over H1 2024.
• Operators report protracted grid-connection waits and transport bottlenecks in key states, threatening to slow the momentum behind new wind projects.
• The Harz Druiberg wind park has begun repowering with the first turbine implosion to replace 23 older units with 13 new generators, more than doubling the park’s capacity.
