Green IT Policy At Lancaster University
Staff should, wherever possible, buy desktop systems that have certified low power consumption, and should buy from a centrally recommended source for which institutional or sector purchasing frameworks have been negotiated.
What is a Green PC or Printer?
A PC or printer especially designed to minimize power consumption. Green PCs draw less power than normal PCs and support sleep modes, in which the computer powers down all unnecessary components when it is inactive. Choosing an energy saving recommended inkjet printer over a non-energy saving recommended one can save you a third of the electricity you would normally use running your printer over a year.
Buying a Green PC or Printer
If you're shopping for a new PC or printer and want to lessen its impact on the environment, there are ways to create a greener computing experience by buying 'green' . Under the Energy Saving Recommended scheme only products that meet strict criteria on energy efficiency can carry the logo. Look for the Energy Saving Recommended logo before you purchase your PC or printer. It's your guarantee that these products are the most energy efficient in their category will cost less to run.

Please note, ISS are not directly involved in the sale of these machines but are simply offering them as examples that match our specifications.
Green Printers
An Energy Saving Recommended printer uses less than 22W when switched on, less than 3.5W in sleep mode and less than 1W in Standby mode. In comparison, an average, new, non-energy saving recommended printer consumes around 30W when switched on, around 5W in sleep mode and around 1.5W in standby. All in all, an Energy Saving Recommended printer uses around 25% less power when switched on and 40% less power in sleep and standby modes.

Power Managment
There is no longer an ISS requirement to leave staff PCs running overnight for application of software updates. Staff and students can power down their PCs and monitors at the end of the working day to reduce energy consumption. Power supplies are available that turn off peripherals when IT equipment is powered off - for example see www.oneclickpower.com
Optimising Your Computer to Save Energy
XP & Vista
To access your PC's power-savings options, click the Start menu, choose Control Panel, then click Power Options (nested under "System and Maintenance" in Vista, if you're not using Classic View). In Vista, you can extend your options by clicking on "Create a Power Plan," then selecting one of three options: "Balanced" (equal parts energy savings and performance), "Power saver" (greater energy savings, but reduced performance), and "High performance" (reduced energy savings, but maximum performance).
For further customization, click on "Change plan settings" under the plan you've selected. This takes you to the Edit Plan Settings page, where you can specify how long your PC and monitor remain idle before they enter hibernation. Hit "Save changes" to implement your tweaks.
Mac OS X
You can access power-management options by choosing System Preferences from the Apple menu, then selecting Energy Saver from the View menu. In the Energy Saver pane, you can choose to turn on and off features such as "Reduce processor performance," as well as determine how long your PC should be allowed to remain inactive before going to sleep. For even greater energy savings, select the checkbox next to "Put the hard disk(s) to sleep when possible."
