Controlling Appliances Remotely : Energy Efficiency - Science Nation

Ever leave the house and then wonder if you left the iron on, or the oven, or maybe the lights? That's something Anthony Rowe doesn't need to worry about. The Carnegie Mellon University Computer Scientist and Electrical Engineer can always keep an eye on his home, even when he's traveled to another time zone. That's because he's rigged his home with sensors he invented with support from the National Science Foundation. Now all he needs is a laptop to help him keep track of all his appliances -- whether they are on or off and how much energy they're using.
