A brief description of on-site renewable electricity generating devices :
The University of Iowa has operated a combined heat and power plant since 1926. The University of Iowa uses traditional feedstock and biomass to generate steam for cost-effective electricity, cooling and water treatment on campus. In 2003, the UI Power Plant pioneered a unique and innovative source of fuel, oat hulls, through a partnership with Quaker Oats in Cedar Rapids, Iowa. Oat hulls provide an economical, environmentally friendly source of fuel. The hulls are a by-product of the cereal-making process at Quaker. They are trucked to the Power Plant and co-fired with coal in the circulating fluidized bed (CFB) boiler. The biomass fuel project supports the 2020 Sustainability Vision - Task 2. The task requires the UI to green its energy portfolio and achieve 40% renewable energy by 2020. Replacing coal with biomass is a central strategy. A variety of biomass fuel sources are being investigated including wood chips, miscanthus grass, timber stand, and organic industrial byproducts.
Additionally, there are rooftop solar panels on some campus buildings.
