yea that was one form that my class did a lot of research about because it is one of the more overlooked forms of energy.
it's actually kind of funny because im in a sticky situation regarding wind energy. they plan on putting tons of windmills out off the shore of two of the most popular beaches on long island, about a mile or something away. the thing is, this would not only create an eyesore and ruin one of the few beautiful things about long island, but it could also potentailly disturb a few things.
putting these giant windmills out in the ocean could and most likely would get rid of large fish communities around the areas which the windmills are placed. the instillation of these large structures would definately disrupt any ocean enviornment. also, the windmills would restrict where boats and fishers could go resulting in decreased fish economy.
i'm not a fisher, nor do i have a boat, but these windmills could also affect something that i take part in - surfing. i'm not sure how much the windmills would actually affect the tides and swells, but i really can't imagine paddling out and seeing tons of 200ft tall structures half a mile away.

of course the other side is the multiple positive results from wind energy, but i really do feel that these windmills could be placed somewhere else where there would be much less of a debate about them.
