Marine ecosystem disruption by offshore wind farms

The construction of offshore wind farms (OWFs) to provide clean energy and mitigate climate change has significant side effects on the marine environment. These impacts include a potential reduction in marine biodiversity and degradation of marine ecosystems due to the construction and operation of wind farms.

1) Offshore wind farms (OWFs) in the North Sea region, which are designed to generate renewable energy, pose a threat to the environment by increasing the likelihood of various disturbances to ecosystems. These impacts include the generation of noise, which can disturb certain invertebrate species such as abalone and squid. The presence of OWFs can also lead to increased sedimentation, which can affect coral fertility and reduce biodiversity. In addition, the unpredictable habitat changes caused by OWFs can facilitate the introduction of invasive alien species, among other problems.

2) The construction of offshore wind farms (OWFs) in the Baltic Sea for renewable energy generation has had a negative impact on the benthic communities living in the area. These communities have experienced a reduction in oxygen levels due to the presence of OWFs, which has affected their ability to obtain adequate food, a trend that had been improving in recent decades. In addition, the decline in the populations of benthic species in the Baltic Sea has the potential to trigger a cascade effect that could affect other marine species.
