Offshore Myth Busters | Offshore wind farms are bad for the environment!?

Offshore wind farms often spark debates, with sceptics questioning their environmental impact. But did you know these towering structures can actually enhance marine ecosystems? Let’s bust the myth that offshore wind farms are bad for the environment and dive into some fascinating science that reveals their unexpected benefits.

Artificial Reef Effect

Offshore wind turbines aren’t just generating clean, renewable energy - they’re building underwater cities for marine life. The submerged foundations act as artificial reefs, providing new habitats for a diverse array of species. From shellfish to larger predators, these structures transform previously barren seascapes into thriving ecosystems.

Biodiversity Boost

Recent research highlights incredible contributions to marine biodiversity:

• Shellfish Growth A single offshore turbine can host up to 4 metric tonnes of shellfish. These shellfish not only filter water but also provide food for other marine species.
• Fish Aggregation Schools of fish, including mahi-mahi and sea bass, are frequently seen circling turbine foundations, benefiting from shelter and abundant feeding opportunities.
• Porpoise Activity Studies show increased activity of marine mammals like porpoises near wind farms, suggesting these areas may serve as hotspots for higher trophic levels.

Marine Protected Areas in Disguise

Offshore wind farms can act as de facto marine protected areas (MPAs). By excluding activities such as commercial fishing, they provide safe havens for benthic (seafloor-dwelling) communities and fish populations.

In some cases, these zones rival the effectiveness of established MPAs in fostering ecological recovery and conservation. For species struggling with habitat loss or overfishing, offshore wind farms offer a much-needed reprieve.

Looking Ahead

While challenges such as seabird collisions and construction impacts must be managed, nature-inclusive designs are paving the way for even greater harmony between offshore wind energy and marine conservation. These designs integrate features like textured foundations and rope-free zones to further enhance biodiversity.

Offshore wind energy isn’t just about powering a sustainable future - it’s about creating one that includes thriving ecosystems above and below the surface.
