MidAmerican Energy takes 46 wind turbines offline after blades fall in rural Iowa
Des Moines Register: MidAmerican Energy says it has idled nearly four dozen electricity-generating wind turbines while workers check them for safety after blades broke off of two similar turbines over the past two months. Those blade failures follow a break earlier this year and one in 2019. The blades that fell recently were on turbines in Greene and Adair counties.
