Ramping up the green energy revolution, one blade at a time! Germany's transition to renewable energy is gathering steam, with wind energy accounting for a whopping 31.5% of the country's electricity mix in 2024. The European Wind Energy Association (EWEA) is jumping on board too, celebrating the importance of wind power with the Global Wind Day on June 15. Part of the plan? The German Federal Environmental Foundation (DBU) funding a project at the University of Applied Sciences Kiel for the optimization of rotor blades on offshore wind turbines.
Hitting the Target: More Power, Less Resistance

To put it simply, the aim is to squeeze more juice out of the existing technologies juggling the expansion goals. With the European Union (EU) setting ambitious expansion targets, we're looking at a 163 GW offshore capacity by 2030 and 300 GW by 2050. The German Federal Environmental Foundation (DBU) is deserves a round of applause for funding the University of Applied Sciences Kiel's project, aiming to optimize the aerodynamics of rotor blades for megawatt-class wind turbines. The project, helmed by Professor Dr. Alois Schaffarczyk, has managed to reduce resistance in the inner part of the blades, possibly increasing the turbine's performance by up to four percent!
Extra Power, a Small Change Makes a Big Difference
Techie's delight
The key to approaching the ambitious expansion targets? One to four percent increases in power yields. It may seem small, but it can supply numerous additional households with clean energy, making a significant difference. The newly designed rotor blade trailing edge, tested through calculations and wind tunnel tests, reduced resistance and boosted the turbine's performance. Researchers have already published their findings online, and Aerovide plans to implement the innovative design going forward.
