    What?

    Are you asking if it's cheaper to leave the TV on or to turn it off?

    TV's use electricity, you pay for electricity. The more you use, the more you pay.

    In other words, leaving the TV on will cost you more then if you turn it off.

    Why would you leave the TV on if you're not watching it?

    Energy star ratings limit the off consumption below about 4 watts. That's 0.004 KW, So in 250 hours, you'll use 1 KWH, typically $0.12 average cost is US

    I think this comes from an old myth about a PC using less energy if it is left on, than turning it on and off repeatedly.

    As everyone has stated above, turn your TV off. Turn off any electronics that are not being used.

    If you have a full setup, like a home theater, there are "green" PowerCenters that you plug the TV or A/V receiver into one outlet, and if the device in that outlet is off, it cuts power to the rest of the units.

    Example:
    Monster Power - 8-Outlet Blackout PowerCenter Surge Protector - MP HDP 900G

    Devices that contain hard drives, don't need to be subjected to mechanical wear. Bumps, power fails, sags in the line voltage aren't good for them.

    Each time the power goes off, the head lands on the platter. If it keeps spinning, it's riding on a cusion of air. 10 K RPM drives exhibit a lot of wear running.

    So, in that light, PC's should stay on during lunch and turned off at the end of the day assuming a work day.

    In the threat of a storm, they should be unplugged assuming no other protection.

    The primary reason is the effect on the hard drives.

    That's good to know. I had never heard any other reason to leave computers on. As far as the electrical noise, that's why I have a UPS and a line conditioner connected between my PC and the wall. Haha.
