View Photos Cashton wind energy project Gundersen Health System and Organic Valley are collaborating on a two-turbine wind farm that is expected to generate nearly 5 megawatts of energy - enough electricity to power 1,000 homes each year. View Photos Lewiston wind energy project Two wind turbines on the Lewiston, Minn., wind farm will generate 4.95 megawatts of energy. The electricity will be fed into the energy grid and used by homes and businesses. View Photos Landfill energy project Gundersen Health System and La Crosse County teamed up on a project that is turning methane gas from a landfill into electricity and heat on the Gundersen Onalaska Campus. View Photos Middleton dairy digester A unique partnership is turning cow waste from farms into renewable energy. Gundersen Health System and Dane County in Wisconsin are partnering with three farm families in Dane County on the GL Dairy Biogas Project. The project offsets about 14 percent of Gundersen's energy needs. View Photos Sun Prairie dairy digester The Sunny Side Digester near Sun Prairie, Wis., generates about 5 million kilowatt hours of electricity annually, enough to power about 530 homes a year. The electricity is added to the local grid in Dane County through Alliant Energy. View Photos Solar thermal water heating Solar panels installed on the Gundersen Onalaska Renal Dialysis Center are part of a solar thermal water heating system. View Photos Geothermal heat pump A geothermal heat pump uses the earth as either a heat or cooling source. The system takes advantage of the moderate temperatures underground to greatly improve efficiencies of HVAC (heating and cooling) equipment. View Photos scroll to top of page
