City Brewery in La Crosse, Wisconsin is using all of its biogas byproduct from the brewing process to create three million kilowatt hours per year of electricity by capturing, cleaning and burning using a process through an engine called a jenbacher.
Down the road from the brewery is a hospital, the Gundersen Lutheran Health System which uses the electricity produced by City Brewery.
This unlikely energy alliance accounts for 10-13 percent of their total needs, but it means they are on their way to their goal of complete energy independence by 2014.
