San Diego  --  After an extensive period of testing, researchers have launched an Internet portal to showcase the real-time measurement and visualization of energy use on the University of California, San Diego campus. The UC San Diego Energy Dashboard (http://energy.ucsd.edu/) allows users to see up-to-the-second information on a structure-by-structure basis for 60 of the largest buildings on the La Jolla campus.
