Energy Saving Tips for Computers
Personal computers and peripherals consume significant amounts of energy. According to the Environmental Protection Agency the average desktop computer wastes up to $75 of electricity annually during times of non-use. With over 1,200 desktop computers on the UIS campus alone, there has never been a better time for users to practice energy-saving computer habits. Best of all, just a few simple and easy tips is all it takes to save energy and money.
NOTE: Tips I and II are intended specifically for desktop computers.
Tip I – Shut down your computer, monitor, and personal printer or place them in a standby mode when you leave the office for more than two hours.
This is ideal for nights, weekends, or other extended periods of time when your computer will not be used. Keep in mind that shutting down your computer is not recommended if:
Another user needs access to a shared folder on your computer
Another user needs access to a printer that is shared by your computer
You need remote access to your computer (with Remote Desktop)
To minimize the need for shared folders stored on a personal computer ITS recommends that departments and users take advantage of eDocs. This will also allow you to access shared files off-campus without the using Remote Desktop. For more information about eDocs, please visit the UIS ITS eDocs homepage.
Tip II – Change your power settings
All modern operating systems have built-in energy management features that automatically manage power settings for the monitor, the hard disks and the system.
To access and change the power settings with Windows 7, simply do the following:
1. Right-click at any point on your desktop (on the wallpaper) and select Personalize.
2. Click on the Screen Saver link in the lower right hand corner.
3. Click on Change Power Settings, and then click Change Plan Settings.
4. The following settings are recommended:
Turn off Display - 20 minute
Put computer to sleep - 2 hours
It is important to note that these settings will NOT affect network storage, network printing, or Remote Desktop functions. If you are unable to shut down your computer due to these reasons, then modifying the power settings is the best option for you.
With Macintosh, use the Sleep pane of Energy Saver preferences, and drag the sliders to set the time for your computer to "go to sleep".
Tip III – Manage your peripherals
In the world of USB cables, Bluetooth, and cluttered desks, it's easy to lose track of all the devices that are connected to a computer. It's important to remember that while these devices may not be in use, they still draw power if they are not turned off. ITS recommends that the following devices be turned off when not in use:
Speakers and microphones
Do's and Don'ts
DO NOT assume that using your screen saver will conserve energy. Screen savers continue to use the monitor at full power.
DO NOT turn on the printer until you are ready to print your documents.
DO review document drafts and emails onscreen instead of printing them.
DO use double-sided printing functions.
DO use email communications as an alternative to paper memos and faxed documents.
