Cost of Leaving Computer On Continually:

If one computer is left on 5 days a week in the Desktop Mode cited above, it will draw 96 Watts. Let’s say that this computer is not used from 4 PM in the afternoon until 8 AM in the morning. This would be a total of 16 hours the machine is on and not in use. We pay the Utility Company approximately $ .06 per KWh which equates to $ .96 a day...not bad? If one computer is left on in every classroom in the district, the cost is now $14,400 per day. In a typical monthly billing cycle, this would cost the district an additional $403,200 per month. Now consider that the buildings are in use for instruction approximately 10 months a year...the impact annually is $4,032,000.

TURNING YOUR COMPUTER OFF EVERY NIGHT DOES MAKE A DIFFERENCE
