They are called ''vampires'' and it's likely there's at least one in your home: common devices that use power and drive up your utility bill, even when they're off.
Wes and Cathy Anderson are on the trail of something invisible that could be costing them $100 a year. They're searching for energy vampires.
Brad Volin, president of Electronic Educational Devices has developed a power meter that can show you how much power an appliance is using, and tells you the amount of money it costs to operate the device.
Wes Anderson's first vampire is his computer center. Even without the computer on, it's quietly drinking up 114 watts. The TV is another electricity leaker. And there's more leakage from the cell phone charger, even when it's not charging. The Anderson's satellite receiver draws 11.6 watts, when it's off.
To fight the energy vampires, try using a power strip.
Volin says, "So when you're done watching TV, you turn the power strip off, and that stops all the leakage for those devices."
Also if you have an outlet controlled by a light switch, you might plug your battery chargers or entertainment center into that, and turn it off when you leave the room.
