These are very alarming numbers, but everything in the world is relative! This is what the proponents of extracting energy from wind power say. They indicate that the main cause of bird death is not the blades of the wind turbine. The vast majority of them die, crashing into the windows of buildings, becoming victims of cats, all kinds of chemicals and traffic. Isabelle Chevalley, Member of Parliament of the Confederation and President of the Association for the Promotion of Wind Energy in Switzerland (Suisse Éole), writes about this, in particular, in her book “The Wind Generator: Between Myth and Reality”.
“The nature of the impact of VEU on bird populations is not fully known to us,” admits Felix Lichti. “Each species is a special case and there are no statistics for them in Switzerland. Nevertheless, it would be a mistake to believe that, they say, a few dead birds “don’t make the weather,” ”he warns. For example, for such a species of birds as the “bearded man” (Gypaetus barbatus), Lichti explains, just two dead birds a year are enough for the state of the population to turn from stable to critical.
Recently, the Swiss Federal Office for the Environment (Bundesamt für Umwelt – BAFU) launched a process of interagency coordination and public expertise on its set of regulations governing the construction of wind turbine parks. “The idea is to provide a practical guide to better assess the impact of wind turbines on wildlife, birds and bats, and thus be able to recognize potential conflicts in advance,” explains Reinhard Schnidrig, head of the section “ Hunting, Fishing and Forest Biodiversity “at BAFU.
