Envision Project Photos

The biomass boiler represents 38 percent of Gundersen's energy independence goal-by far the largest single project in their Envision® portfolio that helped them achieve their goal.

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.

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.

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.

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.

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.

Solar panels installed on the Gundersen Onalaska Renal Dialysis Center are part of a solar thermal water heating system.

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.
