Why are people against wind farms?
Wind farms, like roads and buildings, are considered an intrusion into nature due to their concrete foundations that are dropped several meters into the ground. Opponents of wind power often argue against it by highlighting the fact that the blades of wind turbines can kill high-flying bats and birds.
However, environmentalist groups emphasize the importance of expanding wind power to combat the climate crisis and preserve biodiversity. They believe that transitioning to renewable energy is crucial for the long-term preservation of biodiversity, as stated in a joint position paper by German environmental groups.
To minimize environmental damage, good planning should be implemented. Wind farms should not be built in important nature preserves. Instead, suitable locations include previously polluted areas like former coal mining sites, intensively farmed land, or monocultural coniferous forests.
Modern wind farms are designed to be less dangerous to bats and birds compared to previous designs. They are built much higher, and animals usually fly under the blades. Additionally, new protective mechanisms, such as bat sensors, are in place to halt the rotors if animals come too close. Intelligent cameras are also used to recognize large birds of prey, like high-flying eagles, and shut down the turbines to avoid collisions.
According to the Nature and Biodiversity Conservation Union (NABU) in Germany, wind farms are responsible for the deaths of over 100,000 birds annually. However, this figure is relatively low compared to other hazards. Glass-covered buildings, for example, kill about 108 million birds each year, while collisions with cars, trucks, and trains result in the deaths of around 70 million birds. Power lines cause the deaths of 2 million birds, and hunting leads to the deaths of 1 million birds. Domestic cats alone are responsible for the deaths of approximately 60 million birds in Germany each year.
Industrial agriculture poses the biggest threat to birds, according to NABU. Monocultures and the use of pesticides have caused a massive decline in the number of insects, which are a major food source for birds and their young. Over the past decades, Germany has witnessed the disappearance of 13 million breeding pairs of birds, resulting in 170 million fewer young birds each year.
In conclusion, while wind farms do contribute to bird deaths, the number of fatalities is significantly lower compared to other hazards. The focus should be on addressing the larger threats to bird populations, such as glass-covered buildings, collisions with vehicles, power lines, hunting, and the impact of industrial agriculture.
