Turning Computers off saves $ 2.8 billions.
Turning off/on PC having a CTR monitor and as far as a TV goes will only damage the tube/circuits in the longrun. These should be kept at least in Standby Mode.
As well, unplugging these does not make sense as it will/may throw off the set-up.
As for the cost of letting things run, I did my own little survey using a BluePlanet Plugin Energy Meter, bought at the local hardware store.
The following is calculated with the Residential (mine) cost per KWh of $0.071
-Webcamera 4 watts 7 hrs KWh used 0.03 KWh cost $0.002
-PC#1 62 watts 4:17 hrs KWh used 0.27 KWh cost $0.019
-LapTop 30 watts 2:55 hrs KWh used 0.10 KWh cost $0.007
-T.V (projection) 141 watts 4 hrs KWh used 0.57 KWh cost $0.040
and then:
-light bulb 30 watts -not calculated
-PC#2 off, LCD monitor standby 6 watts -not calculated
-PC#2 running 72 watts -not calculated
also:
-Ovens, Baseboard Heaters, Dryers may be the offenders
to correct the annoying Unplugging Myth:
-Toasters, Can Openers, Vacuums do NOT use energy when NOT running.
What do they mean? Turning Computers off overnight worldwide(?) calculated is that on a on a yearly basis?
Saves $ 2.8 billions?
Let's see:
PC#1 would cost me $0.107292 per day to run. Or $39.16 per year.
Savings projected : $2,800,000,000 / $39.16 per year = 71,501,532 Offending Computers?
Pardon me, if my calculations are correct the whole issue is:
Rubbish!!!!
