Dear Damiando, During my years working for a utility company in californi and promoting renewable resources we worked very closely with US Windpower at Altamont Pass.
Generally speaking, the rule of thumb is it takes an average windspeed of 12-14 mph per day to provide complete cost benefit from an investment point of view and also the so-called "standard offer" contracts that the CPUC offered to incent renewable energy. The mechanical challenge is one of on-going maintanence, tribology, shear, and also environmental impact. The windfarm on Altamont Pass has problems with predator raptors flight path, nesting and therefore lots of raptors losing their lives. It is a big thing. However, wind energy is a complimentary energy source albeit not a constant. I also worked at on windfarm analysis for energy projects on Native American lands and that is a very interesting proposition. Good luck to you. P.
