Recently a new paper was published by our partners Andrew Twelves et al. from the Marine Research Unit at Finnish Meteorological Institute.
The research examines the effect of future wind farm developments in the Baltic Sea and shows that wind turbines can locally alter wind patterns and reduce vertical mixing in the upper ocean. Using a decade of advanced ocean and sea-ice simulations, scientists found that while wind turbine “wake effects” can extend far in the short term, their long-term impacts on ocean conditions are mostly confined to within about 10 kilometers of the turbines.
The study highlights that offshore wind farms are compatible with sustainable energy goals, but careful spatial planning is crucial to minimize local environmental impacts. Aleksi Nummelin, one of the authors, comments : “Our study confirms that the main impact from offshore wind farms to ocean physics are restricted to their immediate vicinity – this makes careful planning even more important as major impacts to important regions can be avoided by small changes to the farm layout and location.’” The results of this work suggest that the placement of turbines could significantly influence how marine ecosystems respond, underscoring the importance of further studies alongside careful spatial planning in the expansion of offshore renewable energy.
