Purdue University has taken some conservation measures including building modifications and lighting retrofits to reduce energy consumption. Preliminary efforts are being made, with input from design students, to install a co-firing boiler that will make use of such alternative fuel sources as switchgrass, byproducts of ethanol production and a local corn syrup processing plant, and, potentially, manure from the Research Farm. The most efficient solar panels designed by students during a class competition were installed alongside solar panels that already heated water for one building. Future plans include the establishment of a formal energy conservation program and the University is in the process of hiring an Energy Engineer to lead that effort.
