    The replacement of fossil and nuclear energy sources for electricity production by renewables such as wind, sun, water and biomass is a cornerstone of Germany’s energy policy. Amongst these, wind energy production is the most important component. However, energy production from wind is not necessarily ecologically sustainable. It requires relatively large spaces for installation and operation of turbines, and bats and birds die after collisions with rotors in significant numbers. For these reasons, the location and operation of wind energy plants are often in direct conflict with the legal protection of endangered species. A recent survey on this green-green dilemma among over 500 representatives by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) concludes that the current mechanisms for the protection of bats in wind power projects are insufficient.

“We found broad consensus among participants,” states Christian Voigt, first author of the survey. “The overwhelming majority of respondents considered the protection of biodiversity to be just as important as the contribution to protect the global climate through renewable energy production.” Most stakeholders agreed that small to moderate losses in the yield of wind power plants in terms of electricity production caused by the consistent application of conservation laws must become acceptable. However, significant discrepancies also existed. For example, representatives of the wind energy industry considered compliance with climate protection targets as more important than measures to protect species.

The conflict between wind power projects and the objectives of biological conservation intensified in recent years because the rapidly rising number of wind plants – there are now around 30,000 on mainland Germany – has made suitable locations scarce. “Besides, only about 25% of wind turbines are operated under mitigation schemes such as temporary halt of wind turbine operation during periods of high bat activity even though the legal framework would require the enforcement of such measures,” adds author Marcus Fritze of Leibniz-IZW.

For the purpose of this survey, the authors selected bats as a representative group of species for all wildlife affected by wind turbines, as large numbers of bats die at turbines and they enjoy a high level of protection both nationally and internationally, and therefore play an important role in planning and approval procedures for wind turbines. The results of years of research led by Voigt at the Leibniz-IZW show that fatalities at wind turbines in Germany affect bat populations in Germany as well as populations in other European regions from where these bats originate.

On the basis of the survey results, the authors argue in favour of a stronger consideration of nature conservation objectives in the wind energy industry. They suggest ways in which the cooperation of those involved in wind power projects can be improved so that both wind energy production and the goals of biological conservation can be satisfied.
