The University of California Irvine is leading the way in energy and water efficiency, reducing its electrical demand by up to 15,000 kW, yielding a peak savings of 68% and saving nearly 4 million gallons of water annually. A cogeneration plant on campus captures heat produced by electrical generation, reducing demand from regional sources and saving the university an estimated 3.7 million kWh of electricity during the 2007/2008 fiscal year. To save water the University has installed ultra low flow urinals and high efficiency toilets, continues to water its landscaping using 100% reclaimed water, and has implemented a clothes washer replacement program to install Energy Star clothes washers in student housing.
