Energy Saving Tip 2: Computer Energy Consumption

Do you realise the how much power your PC or laptop uses?

New computers & laptops consume less power

New computers & laptops consume less power

  • On average a standard desktop computer uses between 65 to 250 watts of power.
  • On average a typical computer moniitor will use between 60 to 120 watts of electricity (dependent on screen size).
  • A laptop will generally consume around 8 to 30 watts depending on the screen size and tasks performed.

There are lots of ways to reduce the power consumption of your computer:

  • Don’t use screen savers, set up your monitor to turn off when inactive for a long period of time. When activated, a screen saver will run the monitor at the full amount of power usage.
  • If you are still using an old CRT monitor switch to a newer flat screen LCD one. In addition to freeing up lots of room on your desk, you will also be making an energy saving between 40 to 60%/.
  • Set up your laptop or computer to sleep or standby after a long period of inactivity. It will only take a few moments to re-boot next time you sit down ready to use it.
  • When you are nipping out or leaving work, turn off your computer and monitors. Don’t leave the monitor on stand by, press the button and switch it off. If you have a networked printer in the office, do you ever switch it off?
