Several cases occurred where the housing of wind turbines caught fire. As it is normally out of the range of standard fire extinction equipment, it is nearly impossible to extinguish such fires. In several cases one or more blades were damaged or torn away. In 2010 70 MPH storm winds damaged some blades, prompting blade removal and inspection of all 25 wind turbines in Campo Indian Reservation in California, USA. Also several wind turbines collapsed catastrophically.
This is wide-spread enough and important enough to address in a separate post. It touches on why free fuel in the form of wind or solar isn’t enough to make “green” energy cost effective. Ask yourself why are there 14,000 idled wind turbines in Northwest?
