The California Plug Load Research Center (CalPlug) is the leading enabler for energy efficiency solutions in the use and design of appliances and consumer electronic devices. CalPlug is initially sponsored by the California Energy Commission and Regents of the University of California to promote a cleaner, more efficient State of California. The center focuses on emerging technologies and user behavior studies for plug load devices. CalPlug addresses challenges in plug load efficiency for both residential and commercial buildings by collaborating closely with utilities, manufacturers, advocacy groups, research institutions, and energy policy makers.
