Our current turbines have no environmental impact except visual, but very limited.

The propellers rotate very slowly (between 20 et 40 t/min) so they do not damage the submarine flora and fauna.

A lot of tests and experiences carried out in various sites, rivers, seas, estuaries have never shown any impact on the environment.

Some fish species come and play during hours with the turbine, but they never touch and get never touched by the propeller!
