What are some trusted sources of information of windmills? Also, recommend a book on it?

Question

I have to create an essay about windmills and how it is more efficient as a reliable energy source. Besides wiki, can anyone find a new source of info?

Answer 1

The first link below covers the history of windmills extensively, but only just touches on modern day wind power sources.  It does have a great selection of book references though, including several discussing their history and modern day value.

The American Wind Energy Association (second link below) has a staggering amount of information, resources, articles, events, etc.  It also has a selection of books available (though most of the sources on the site will most likely be able to provide you with answers).

It's impressive the size, scope and reach of this organization.  Oh, and the baseball caps in their online store are really cool!

Answer 2

check out the companies that make them- Vestas in Europe and GE in US
