Biodiversité

Au bord du lac du Salagou, dans l'Hérault, des techniciens, perchés en haut de pylônes, installent des protections pour éviter que des oiseaux de grande envergure ne s'électrocutent.

Avian mortality is one of the most negative impacts of wind energy. Consequently, techniques that effectively reduce avian collision rates are necessary. One of such method is the stop-turbine system, otherwise known as a Turbine Shutdown System (TSS). Here, we analyzed changes in mortality during 15 years, starting two years before the application of a selective stopping protocol (2006–2007) and after 13 years of application (2008–2020). This protocol was applied in Cadiz area (southern Spain) to 20 wind farms, totaling 269 wind turbines
