I'm all for strategies to reduce the effect wind turbines have on birds/wildlife as described in the link you posted (thank you) - that would be great. Like you I want us to protect our wildlife. I still think we urgently need more renewable energy and part of that is likely to be wind...
My understanding is that the number of birds killed by wind turbines is far far fewer than those killed by burning fossil fuels/the environmental impact of this. No I don't have a source/reference to post now, might be able to find out more or someone else can help me?
