Calculate your office energy waste

Office energy wastage calculator

Number you leave on standby overnight	Type of device	Approximate power wasted
	PCs (newish PCs with LCD monitors)	Watts
	PCs (newish PCs but with non LCD monitors)	Watts
	Very old PCs with manual, clunky power switches & old monitors	Watts
	Personal printers	Watts
	Network / workgroup printers	Watts
	Photocopiers	Watts
	Mobile phone chargers / other mains adapters	Watts
	Coffee machines (that have a built-in tank of always-hot water)	Watts
	Non-refrigerated / perishable vending machines	Watts
	Network routers, etc, that IT tell you you can switch off overnight	Watts
	Scanners	Watts
	Computer speakers	Watts
	Microwave ovens	Watts

Percentage of PCs left running overnight		%
Of those PCs not left running overnight, what percentage of PCs are shutdown, but not turned off at the plug overnight?		%
How long is a typical working day?		hours
Do these PCs, etc, get used "normally" at the weekend?
BTW, this means your computers are typically idle for this many hours per week
How much, on average, do you pay for your electricity?		pence /kwh

Total power wasted when devices are idle		Watts
Total power wasted per year		kwh per year
Using Enistic, you could save up to		Kg of CO2 per year
... and up to £		per year

Assumptions

N.B. This model assumes the following:

Your office is pretty typical, with no strange power-hungry devices except those listed
That you download and use the Enistic desktop solution.
There are roughly 4 million businesses in the UK (Federation of Small Business statistic) and each business has on average 1.5 PCs (a hopefully conservative estimate)
Devices such as telephones, burglar alarms, CCTV systems, etc, are left on all the time and Enistic equipment is not used to reduce their energy use.
