Energy-Saving Computing: Managing System Usage

Keywords:

When a computing device is not in use, turn it off. For computers, the break-even time (in terms of energy consumption running versus restarting) is around 18 minutes (although staff time waiting for a PC to restart should be considered).

Contrary to popular opinion, turning off and turning on a computer several times a day is not potentially harmful, as long as the system is turned off cleanly; i.e., by the operating system.

Where resources such as servers and network devices are needed only during known times, they can be set to automatically turn on and off.

To maximise energy savings, once the system has turned off, turn off power at the wall-point. If your computer has a on/off rocker at the rear of the power supply, that achieves the same result. Don't merely leave computers and peripherals on standby – this still uses a substantial amount of energy. Turn off printers using their power switch. To automate this, use power timers.

Also, when a software supplier releases a new version of the software supplied with the computer (not merely an update), don't automatically go out and buy it. If the software you have is doing the job, do you need to spend the money? And the new version will probably require more hardware resources, hastening the day when you will need to upgrade or replace existing hardware, and shortening the life of your existing investment.
