I can't post links yet, but I saw an article recently about the Altamont Pass wind farm in California and how environmentalists are getting it shut down. Too many birds migrate through that corridor and are splatting on the turbines.
And I agree about hydro dams. Here in Washington we see their drawbacks clearly.
It seems like solar power is a favorite for environmentalists, but I'm not sure how practical it is. It would take so much acreage to generate much power - surely that would affect someone's habitat.
I'm not a smarty-pants on this issue by a long shot, but it is my understanding that nuclear power in these modern days is very safe. The disposal problem is still there, but the plants are very safe. We have some old, unused nuclear plants in my state...I wonder if they can be updated?
