Unplug

Even when all of your home electronics are turned off, many continue to suck down energy. The main culprits: televisions, VCRs, DVD players, stereos, phones and microwave ovens. Idle TVs cost U.S. consumers $600 million annually, or $5 per household, according to the EPA. One solution: Plug the items that can truly be turned completely off into a power strip, and then use that as your on/off switch.
