Unlike most wind proponents, I’ve researched the topic pretty thoroughly and have thus built up quite a library of materials. Here is the link to Amherst Island Wind Info’s library.
At my companion Wind Farm Realities web site I have another large collection of reference materials, and there may be some duplication between the two.
And if that isn’t enough, Wind-Watch has its own reference library, probably with a fair amount of duplication.
I think I can guarantee that among these three libraries you will find more information regarding all aspects of wind turbines than you will find on all of the proponent web sites put together.
