Did you know that even when your appliances are turned off they are still costing you money? According to the U.S. Department of Energy, 75% of appliance energy use occurs when your appliances are turned off. The good news is that by unplugging them when they're not in use, you can save both money and energy in your home.
The libraries in the Minneapolis/St Paul region offer free power check meters and computer software to help consumers understand the cost of their appliances/lighting/gaming and the ROI of replacing them. Kids love using the meters and watching the energy change in the on/off/stand-by position. Cindy Ojczyk More Than a Beautiful Home
I wrote a paper for IEPEC conference in Boston on this topic. Interesting how much many small overlooked devices use, including settop boxes and small speaker subwoofers! http://www.iepec.org/conf-docs/papers/2011PapersTOC/papers/110.pdf#...
That's true to my knowledge.
