I never said anything like that.

Rather premature failure needs to be considered in operational lifetime of turbine. Not all damage can be repaired or more accurately repaired cost effectively. Some damaged turbines will be scrapped.

Eventually I am sure some studies will come out to see how the real world life expectancy compared with 30 year quoted lifespan. It simply will take time. Most large scale wind projects are relatively new. The few large scale projects with >20 years history are not numerous enough to provide statistically valid samples across diverse geographical locations.

In another 5-10 years we will have better idea of the true lifespan of wind.
