and you have data that supports 15 years? I know from my extensive trips to Germany that they have wind farms supplying small towns (10's of thousands) that were in operation before my first trips in '96, and still are today). Further, not sure where you get "high maintenance"? Would you care to do some research on the maintenance it takes to run a coal fired plant like Commanche down in Pueblo, or any other plant for that matter. Or a nuke plant for that matter, I can guarantee you it is substantial. With regard to the no wind thing, I can't recall a day since I moved to northern Colorado 2 years ago that we haven't had enough of a breeze, especially after sunset, to run a wind turbine, they are actually designed to run quite well on a breeze of only a few miles per hour. That will improve substantially with the new generation of wind turbines coming online that use air core generators and direct drive, both technologies which will greatly reduce cost,complexity, starting torque, and raise efficiency as a result.
