If you knew where all the energy zooming into your house was being used and wasted, would you change the way you consume power? One company is banking on it. Our Power Trip heads to Redwood City, California to talk to Joe Polastre, CTO and co-founder of Sentilla. The company has invented an unassuming rectangular box that tracks —dollar by dollar, watt by watt—how much energy the appliances in your home are using. Clothes dryers and air conditioners beware: your energy guzzling ways are secrets no more.
