For over a decade, the university has implemented energy conservation measures that have saved an average of 13.3 million kilowatt-hours of electricity per year. Savings generated by these measures are earmarked for reinvesting in additional energy savings projects. For the past two years, the university purchased wind Renewable Energy Certificates (RECs) for 30 percent of its annual electrical consumption and has committed to purchasing RECs for the next two years, equating to 14,500 megawatt-hours of renewable electricity per year.
