Summary and Info
I think this book has a good overview of wind energy and some of the basic considerations when it comes to designing wind turbines. As an engineering student researching wind turbines, I personally would have liked to see more content on design instead of wind resource and siting. Having said that, the book is meant as an overview intro book, so it contains exactly what is says it does.
If you are interested in much more technical content and wind turbine design, I highly suggest The Wind Energy Handbook, by Burton, Sharpe, Jenkins, and Bossanyi. Depending on how technical you are, it may be much more than you're looking for.
Even though I haven't done any yet, I do like that this book includes end-of-chapter problems. This is beneficial if a course on wind energy required this text.
