Why Do Wind Turbines Have Three Blades?

There is a lot more to this subject than I have covered in this video, this is just the basics. I have used the Wind Turbine Handbook as my primary reference material, it covers pretty much everything you need to know about wind turbines. If you are studying this subject academically I highly recommend it.
