The University of California, San Diego has been accumulating awards for its savvy use of a constellation of power generation and energy-saving technologies. The campus already controls a fully functioning microgrid - including a cogeneration plant - and, as befits a research institution, is constantly looking for new ways to make its energy system smarter. This "living laboratory," as campus leaders like to call it, demonstrates what it takes to build a smarter grid and why the effort is worth it.
