Offshore wind energy ecological impact research

Research in the North Sea and Norwegian waters is examining the ecological impacts of expanding offshore wind energy infrastructure.

In the Netherlands, studies under the Dutch Offshore Wind Energy Ecological Programme (WOZEP) are investigating how electromagnetic fields (EMF) generated by subsea electricity cables may affect marine species such as sharks, rays, harbor porpoises, and various invertebrates. Scientists are monitoring potential changes in behavior, migration, and reproduction, while the Dutch Fishermen’s Association has called for more extensive research to address knowledge gaps regarding long-term exposure.

In Norway, research into offshore floating structures indicates potential impacts on species in deeper waters. A study at the Hywind Tampen site found that ling caught near the offshore structures were in significantly poorer condition compared to those at comparison sites. As energy demands drive the deployment of floating installations into deeper seas, the ecological consequences of these structures remain a primary focus of study.
