Blade failure

Farmweek, Aug. 2, 2010

One blade of an Invenergy LLC wind turbine in a cornfield east of Grand Ridge in LaSalle County split and buckled apparently as a result of strong winds that blew up suddenly during the weekend of July 24-25. A spokesman said the turbines are designed to come to rest with one blade pointing down and parallel to the base of the tower in the event of high winds, but the winds came so quickly the safety mechanism didn’t have time to kick in.
