Cost of turning monitors off vs. leaving in sleep mode
I'm trying to determine the approximate cost of leaving on your computer monitor overnight (in power-saving sleep mode) versus turning it off at night and on when you need it.
This is to settle a bet, so it's important :P A few studies I've googled seem to suggest a $20 annual? power savings for CRT monitors, which consume about 3-5 watts/hour, if I'm translating the studies properly Anyone have a reference source that I can point my opponent to, to validate an approximate number? I need to calculate an approximate cost/hour value, rather than an annual cost. If $20/annum is pretty close, then I lose. Thanks for any help. |

wouldnt cost/hr = annual cost/#hrs in a year?

Cost per hour=KW*($/KWH)
If you know how much power it consumes in KW (5W/1000=0.005KW) and the cost per KWH for electricity (I think this is listed on my electric bill, but I don't remember), then it's a simple calculation. |
