Savings you can bank
|
A typical desktop computer uses around 150W of electricity and, left on permanently, can add up to £150 per annum to the electricity bill.
If the computer is only used during office hours, over £100 per PC could be wasted every year.

Of course, not all computers use this much electricity and many organisations already try to turn off unused equipment, but do you know where
your organisation stands?
It is may be impractical to completely remove all waste but PowerMAN can help you bring it back to manageable levels.
That is why we use a projected saving of £60 per computer. We have found some sites where the saving was less, and a number where it was significantly more. We feel this is an honest projection of what a typical organisation could save.

Notes: Based upon representative 110W typical PC with 40W TFT monitor (0.15kW total) charged at 12p/KWh previously powered-on for 24 hours per day and subsequently powered-on only weekdays for 10 hours per day. This excludes the additional cost savings available when the equipment is located in an air conditioned environment. Most modern computers are typically 85-120W and a typical LCD monitor is 35-50W.
Calculation is PCs x kW(atts) x £/kWH x hours x days x weeks = Annual cost
