Do wind turbines harm animals?
There have been many anecdotal reports suggesting that wind turbines cause harm to animals — livestock, non-flying wildlife and pets — in addition to birds and bats and (oh yeah) people. As there are no scientific studies on this topic, there is virtually no consideration of potential adverse effects on these animals that don’t know about required setback distances.
Here is a good article that references many of these reports and gives an idea of the potential extent of the problem. See http://eastcountymagazine.org/node/9615 .
