Glinting in winter sun. In mid-Winona County on Lewiston’s outskirts. The turbine is one of four owned by the Gundersen hospital in LaCrosse, two in Lewiston and two near Cashton in Wisconsin. Together the turbines generate electricity to power the equivalent of 1,200 homes. The wind farms also lessen the strain on local grids during weather extremes. Image: Steve Lunde
