San Diego Gas & Electric found us. They want to move to “demand management,” where the price of electricity changes based on the load on the energy grid. Like Uber’s peak-pricing, but for electricity. On a hot day when everyone cranks their AC at the same moment, the load surges. And so does the price. Energy companies need a way to communicate the change in price continuously throughout the day. They need an always-on, ambient display that people so people will notice and respond. Dozens of energy companies conducted multi-month pilot studies and came to the same conclusion: The Ambient Energy Joule motivates people to conserve 20% of their energy use when prices go up. Arnold Schwarzenegger, then governor of CA, called this program (don’t forget the accent) “smart shift and save.”
