Abstract
This paper addresses the issues arising from the correlation between upcoming investments in the development of offshore wind energy and the fauna of the Baltic Sea. It presents the challenges related to the construction of offshore wind turbines and the requirements set by the European Union. Information regarding the fauna of the Baltic Sea and the threats to the body of water resulting from human activities is provided. Conclusions are drawn regarding aspects of offshore wind farms (OWFs) that may be harmful to the fauna of the Baltic Sea, as well as those that have a positive impact on animals. Finally, solutions are proposed to mitigate the negative effects of OWFs on the marine environment and enhance their positive impact.
