Small wind turbines harm bats
It’s not easy being eco-friendly and energy independent. Just ask the bats that live near small wind turbines.
I hate reading news like this, but we must not be blind to what we do, even if we do it with the best intentions (or just to save a bit of cash).
New research shows that small wind turbines, like the ones you might mount on your roof or erect in your backyard (no innuendos intended), can reduce bat numbers by up to 54%.
The leader of the Stirling University study, Kirsty Park, is quoted by the BBC:
Based on our results, we recommend that turbines are sited at least 20 metres away from potentially valuable bat habitat. This will help us to maximise the benefits of renewable energy generation whilst minimising potentially adverse effects on wildlife.
The study found that bird populations were not significantly affected by small wind turbines.

Reasons as to exactly why large wind turbines cause bat fatalities are as of yet unknown, though it may have to do with migratory bats being attracted to the turbines or the change in air pressure caused by the rotating turbines resulting in disorientation.
