German wind mills contribute to migratory bat deaths

Clean Technica reports a new study is out that states a large number of migratory bats are being killed by German wind turbines. This comes out at the time when bats are in the process of migrating between the winter and summer months. While multiple studies have been done covering the same topic, Clean Technica states this manuscript published in the European Journal of Wildlife Research deserves attention.

According to the research (as per the press release), each wind turbine causes the death of approximately 10 to 12 bats per year if no mitigation measures are put in place. Naturally, these numbers vary based on geographical location and type, as well as the type of turbine.

However, according to the research, not many of these turbines are believed to have any mitigation measures. This led the researchers to conclude that if all the wind turbines in Germany were put into operation without any mitigation measures, nearly 250,000 bats would die per year. Of these numbers, approximately 70% can be attributed to bats migrating between summer and winter habitat.

“We assume that only a fractional part of all 24,000 wind turbines constructed until 2014 meet the necessary standards for the conservation of protected species,” said one of the report’s authors, Christian Voigt, biologist and bat researcher at the German Leibniz Institute for Zoo and Wildlife Research (IZW). “Many, especially old, turbines run without any or only insufficiently implemented mitigation measures.”

However, while attempting to point out a bias on the part of the study by committing an unpardonable sin of the research doing what scientists were supposed to do by focusing mainly on bats and not the turbines, the commentator demonstrates his bias while attempting to reveal the study’s.

… U.S. News and World Report which took it upon itself to look at the numbers of birds killed each year by electricity sources in the US, the number of birds that meet their maker at the hands of wind turbines is comparatively small when compared to coal.

And of course, nothing comes anywhere close to causing bird deaths more than the cat, which on the whole manages to kill anywhere between 1.4 and 3.7 billion per year!

Finally, a study published at the end of 2014 showed that, in many cases, seabirds avoid collision with wind farms.


First off, the study’s focus was the demonstrate how wind turbines in Germany are killing migratory bats. It was not research comparing how other forms of energy might kill migratory animals. Admittedly bats do not have the collision detection faculties like birds in order to avoid collisions, but its clear the author is attempting to cover for wind turbines by explaining away or attempting disinformation related to the deaths of bats and other winged creatures that are killed resulting from collisions with wind turbines.

The fact remains environmentalists will cry murder when winged migratory animals and even insects are affected by man-made energy sources like coal or pesticides but express little concern when their policies result in the deaths of the same creatures whose existence they championed in order to condemn fossil fuels or pesticides. It’s only okay for bats, bees, eagles and other winged creatures to die when environmentalist policies are used, not when people other than environmentalists come up with ideas on how to make people’s lives better.
