Think of your computer (CPU with 15"/17" monitor) as a 130 watt light bulb.  Leaving a 130 watt light bulb on when not in use may seem diminutive, but having 10,000 PCs on campus being switched ON when not in use, is significant!

Do your sum: each PC consumes about 2.15 cents/hr (@ $0.01656/watt/hr) of electricity when left switched ON. Let’s say 1 PC left switched ON after office hour from 6.30pm - 8.30am (14 hrs) consumes around 30 cents/day/PC.  With 10,000 PCs, this worked out to be $90,000/month in utility bills for the University!

As an individual, a little effort to switch off your PC can help saved unnecessary wastage, and the environment.  And by activating your monitor to sleep mode during office hour can lower power consumption to below 30 watts & emit less carbon dioxide.  To 'wake' your monitor up, simply move your mouse or touch your keyboard.
