Yup. They're big. I understand why they'd be scary!
Hey, we tried something... maybe we'll look back in the future and say "hey, we tried this, but it turned out not to be the best idea... we moved on." I know there's a huge back lash over them here. (eye sores, disrupt bird migratory patterns, dangerous, ect.) I thought they were awesome to see because they are huge... but would rather they go a different way if all that is true.
P.S. - The first pic reminds me of one of my favorite parks here. It's about 5 acres of a cut-through to the university and it's allowed to be absolutely natural (rare for here) and do it's own thing with no interference. Just beautiful. (Just 1 paved path through the middle is all they touch.)
Yes.. they might and do result in all you've listed, however they are an effective and serene power source which make them indispensible.
In other words the only solution would be mounting them in remote locations, far from natural life, which I think is the case in this pictures.
It's funny about wind turbines, I never hear people complaining about power pylons (there are some in the pictures); they are far more ugly and much more dangerous. I don't know about the birds, but turbines move pretty slowly, if birds can't fly past them then it seems a bit odd to me. I saw a statistic the other day that cats kill millions more birds than wind turbines do; who knows the truth on that one...
I'm, usually, the only one in a group that hates those. (Hate is a strong word. I know they are necessary, for now.) I try not to say too much to further the tinfoil hat rating I already have with friends and family! hehe. However... Since you brought in up. :) There are medical studies that plot cancer instances geographically. There is at least one study (I would reference but don't remember where I saw it years ago) that showed the instances of cancer, clearly, traced the paths of the high tension power lines in populated areas. I have, ever since, avoided living anywhere near them. The effect diminishes rapidly with distance. So I usually allow, approximately, half a mile buffer either side as a "don't live there" zone. More if you have the options.
But... the truth is hard to discern. I just listen to as much as I can and make the best, somewhat educated, attempt to chose the best options as they come up.
The wind turbines are up for debate... but the cats stay! I like 'em! ;)
