SCIENTISTS SEEM TO HAVE SOLVED THE MYSTERY of why bats are killed by wind turbines, and they think they can use this knowledge to prevent bat deaths. This good news comes from the Journal of Wildlife Management via Science Daily: Bat deaths can be reduced by making sure that the blades of the turbines do not turn (at least not much) when wind speeds are low. Taking this precaution doesn’t significantly affect energy output from the turbines, either. The idea is already being successfully used in some locations.
There’s a lot more to the story, however, so if you’re interested I recommend checking the following sources:
My earlier post on windpower and wildlife can be found here. For the record, a (“up to”) 60% reduction in bat deaths isn’t enough to make me ultra happy about the popularity of wind power. But it is good news, and perhaps this discovery will lead to others that will reduce bat deaths even more.
Many thanks to Carole Browne of Conservation Gardening for mentioning this news on her blog.
