Even Small Wind Turbines Lower Bat Activity by Half

Even Small Wind Turbines Lower Bat Activity by Half

By Derek Markham, TreeHugger

One of the drawbacks of large wind turbine installations is the loss of bats, which play an important part in the environment and in our economy (up to $53B a year!).

Right now, researchers are exploring new solutions to reducing bat deaths at large wind farms, but with the rising number of small wind turbine installations for residential and urban areas, bats may lose more valuable habitat.

A research study by Dr Jeroen Minderman, of the University of Stirling, is the first study to examine the impacts on local wildlife activity from small wind turbine installations, and the results suggest that the microturbines could significantly decrease bat habitat in their immediate area.

“Previous studies have shown that birds and bats can be killed by colliding with large turbine blades or that wildlife may avoid the surrounding environment, leading to effective habitat loss. To date, studies have focused solely on large-scale wind farms. We therefore felt it vital to address this knowledge gap by determining whether such effects are also applicable to small wind turbines, to improve planning guidance and deter badly-sited turbines in the future.” – Minderman

The results of the study showed that bird activity was not significantly affected by the turbines, but that bat activity was 54% lower near operating units. The authors recommended that wind turbines be kept at least 20 meters away from important bat habitat, and hope that their findings can help guide future installation guidelines.

I do believe it's important to protect each part of the ecosystem. Bats are a vital part of it, so any disruption should be remedied. But I still like wind better than nuclear. Thanks.

Research into SOLAR POWER! Nothing gets hurt with solar power. Problem is the mega rich wouldn,t make money from it!

So glad that people care!

We can build wind turbines and windmills -- where the birds and the bats do not fly. We can and have studied where birds and bats fly.

We can have birds, bats, wind turbines, wood wind turbines and wood windmills -- all exist !

I am looking for the solution .Noted,thanks.

This is tragic. We need safer turbines. Wind power is not more important than bats' lives.

Sad...have to find better turbines and protect bats!

We need to find a way for both to coexist. Save out bats!

I had a colony of bats living in my roof, but the acquisition by neighbors of Mynah birds caused them to move away. A college student did his thesis on the Mynahs and as an aside discovered that the birds could imitate the bats navigational anti collision ultrasonic tones, confusing them, causing missed flying insects and collisions with each other. Now that the bats have departed, we see insects and mice in the house.
