A PC left running 24 hours per day would use £59 worth of electricity over a 12-month period and create 716 kg of carbon dioxide emissions a year.

For a typical business desktop user, implementing advanced power-management policies alone – without compromising productivity – could save 60% of the electricity consumed.

Here are just a few suggestions to save energy, your money and the planet:

  • Turn off all desktop computers and peripheral devices, including monitors at night and during any prolonged absence such as weekends or vacation time.

  • Switch off at the mains switch or, where appropriate, at the power bar or plug connector. Unless you flick the switch a PC that is apparently turned off will still be using power.

 

 
  • Use your computer's energy-saving mode: you should be able to turn the brightness of the screen down, or set it to turn off if you haven't used it for 5-10 minutes

  • Upgrade your CRT monitors to flat screen LCD monitors. LCD monitors reduce energy consumption by a third.

  • Turn down the brightness setting on your monitor. The brightest setting on a monitor consumes twice the power used by the dimmest setting.

  • Don’t use a screen saver. Screen savers are not necessary on modern monitors and studies show they actually consume more energy than allowing the monitor to dim when it’s not in use.

  • Use a laptop instead of a desktop. Laptops typically consume less power than desktops.

  • Choose ENERGY STAR approved products which help save energy through special energy-efficient designs, allowing them to use less energy to perform regular tasks, and automatically enter a low-power mode when not in use.
