This is the book we used in college for our Energy Systems class. It was a renewable energy class that was half wind and half solar. The wind portion had lots of good information in it, and I tried to buy the book from our school... they were literally just printed out on white printer paper with a card stock front and back, and they wanted $140... I looked at them online at Amazon, and they wanted $160! A simple search on the internet for "
Wind Energy Systems Gary L. Johnson" will get you some places where you can download it for FREE. It's an extensive book, and I have to admit I don't remember everything that was in it, but I found it more comprehensive than other wind energy books I have seen. Hopefully people find it useful, and I will try to dedicate some of my time to going over specifics from the book, that is if people would find it useful.
