Around 46 MidAmerican Energy wind turbines have been put on idle for inspection after a second wind turbine blade broke in two months, according to the Des Moines Register and KCCI Des Moines

The most recent break occurred on Thursday near Paton in Greene County. The blade had a lightning protection system similar to a previous blade that broke off a turbine and fell into a cornfield last month in Adair County.  

The blades are 177 feet long and weigh 18,000 pounds, according to the Associated Press.

MidAmerica has more than 3,000 wind turbines in Iowa, with wind energy making up 42% of the total energy production in 2019.
