“These off-shore wind turbines kill much more than expected”: no one had anticipated the devastating impact on marine fauna and European coastal ecosystems

Offshore wind turbines, a symbol of the sustainable energy future, arouse many questions about their impact on marine biodiversity. Furthermore, Installed offshore to preserve the coastal landscapes, they stand proudly at sea, far from looks. However, their presence raises questions about marine life which evolves around these colossal structures. However, In the Netherlands. In addition, a team of researchers conducted an in-depth study to assess the impact of these wind farms, “these off-shore wind turbines kill using an innovative method based on environmental DNA analysis. In addition, This non -invasive approach made it possible to collect precious data on the sharks. Moreover, the lines that populate these waters.

An innovative analysis method – "these off-shore wind turbines kill

Dutch researchers have opted for an original method to assess the presence of marine fauna. Therefore, around offshore wind turbines. Furthermore, By taking 436 seawater samples, they were able to identify the DNA of five species of sharks and rays. Meanwhile, Among them, the curly line and the common needle have been detected. This technique is based on the analysis of the traces of cells. genetic fragments left in water, a method respectful of the environment and vulnerable species. It thus avoids the capture or marking of animals, while providing tangible evidence of their passage in these energy zones.

This detection method. called non -invasive, is still rarely used, but it offers a precious “these off-shore wind turbines kill overview of the interactions between wind turbines and marine fauna. The results show that although wind turbines can act as artificial reefs. thus promoting the reconstruction of local ecosystems, low DNA detection (only 8 % of samples) raises questions about the real density of these populations in the North Sea.

Potential impacts on fauna – "these off-shore wind turbines kill

Although the presence of certain shark. ray species is confirmed, the question of their sustainable use of these areas remains unanswered. A genetic trace is not an infallible indicator of the activity or housing of these animals. They could simply cross these areas without establishing themselves there. In addition. other factors, such as the underwater noise generated by maintenance vessels and electromagnetic fields emitted by cables, can disturb the electrosensory perception of sharks and rays. These species depend on this capacity to locate their prey and orient themselves.

These disturbances could limit their ability to exploit these areas as shelters. Offshore wind turbines. although they reduce CO2 emissions, should not be established without an in -depth study of their impacts on marine fauna. The energy transition must be done in harmony with the preservation of biodiversity.

Wind turbines as artificial reefs

Offshore wind turbines are not only energy. producers. They also offer submerged structures that can serve as artificial reefs. These infrastructures provide anchor supports and create new habitats for various marine species. By prohibiting background trawling, a harmful practice for seabed, wind farms promote the resettlement of certain fragile species.

However, this artificial reef function is still being studied. The evidence of the use of these areas by marine fauna is limited and requires more rigorous documentation. The complexity of marine ecosystems requires a precautionary approach to integrate wind turbines in an ethical and sustainable way.

The need for a balanced approach

The development of offshore wind turbines has undeniable advantages in terms of reducing. CO2 emissions. However, it is crucial not to neglect the potential impacts on marine ecosystems. The researchers highlight the importance of not adopting too dogmatic discourse on the benefits of renewable energies. without taking into account the needs of the species that populate these sensitive environments.

It is imperative to see the sea as a living space, requiring special attention when installing new infrastructure. The energy transition must be an opportunity for reconciliation between sustainable development and the preservation of marine biodiversity. A delicate balance “these off-shore wind turbines kill that is essential to maintain.

While we strive to reduce our carbon footprint. it is essential to question the overall impact of offshore wind turbines on marine biodiversity. How can we reconcile the need for rapid energy transition with the preservation of fragile marine ecosystems?
