As part of the University's energy conservation measures, energy audits have been conducted on some buildings, Vending Misers have been installed on soda machines, and some lighting and electric motor retrofits have been performed under the Energy Star program. The University has helped install three solar hot water systems in local schools and is installing another system to provide hot water to one university building. The University is conducting a pilot study project using photovoltaic-powered streetlights and also has a pilot project in progress that is exploring alternative light shelves. The potential of using a B20 biofuel mix for the campus's diesel vehicles is being researched, as well.
