Forgot to turn off the lights? There's an app for that

The simple fact of making power flows known — by putting electricity meters inside the house instead of outside — can lead to big efficiency gains; add in time-of-use pricing and real-time displays of that use, build in a few other smart apps and management tools, and pretty soon you're looking at massive gains. A test run by Colorado's Xcel Energy in 2007, for example, found that time-of-use pricing, smart meters and automated thermostats could reduce energy use as much as 54 percent at moments of peak demand. And since it's estimated that just a 5 percent reduction in peak energy demand across the U.S. could eliminate the need for more than 600 new power plants by 2025, these are by no means small steps toward a cleaner energy future.
