Reducing the energy used by computers
Starting your savings on the ecoBiz program is easy, and our experts have put together some frequently asked questions when it comes to saving energy used by computers in the workplace.
1. Will turning my computer and monitor on and off wear out my system?
No. In fact, powering your computer on and off daily is a good habit for proper PC maintenance. It reduces wear on the computer fan and enables updates that require the computer to shut down. Leaving your computer on also causes dust build-up, making it vulnerable to power surges.
2. Do screen-savers save energy?
No. Screen savers use monitors at full power and were only designed originally to prevent 'burn in'; they are not needed on newer monitors at all. Not only do screen savers draw power, but they also keep the computer’s central processing unit from shutting down. It is much better to set your computer to sleep mode where the monitor switches off when not in use.
3. Do I need to turn off my monitor?
Yes. In general, monitors consume more energy than computers. Switch them off when not in use.
4. Are power-saving settings automatically activated on my computer when I purchase it?
No. Power management settings allow the computer and monitor to enter low power states when idle. These settings can reduce usage on average from 60-90 watts down to 2-10 watts.
If you don’t have time to turn off all your appliances consider using an energy saving powerboard that is connected to the master socket. When this one appliance is turned off the power board (generally with the main computer plugged in) senses this and automatically switches off power supplied to the other sockets on the board. When the primary appliance is turned on again, the power to the other controlled sockets is switched on. They usually have one socket that operates with 'always on' status if you need an appliance, such as the fax, that must have continuous power to operate. The board also provides a high level of surge protection. Alternatively, consider using a simple plug-in timer.
