From a technological standpoint, today’s electrical grid isn’t terribly different than the one laid out in the days of Thomas Edison—just a lot more strands. This is about to change. A “smart” grid is emerging as modern-day information technology is applied to the infrastructure that delivers our electricity. While innovative ideas and technology can improve reliability and reduce costs at all points in the system, the real value of a smart grid cannot be unlocked without smart buildings connected to it.
