Environmental impactMonitor settings

Computer systems require a lot of power at start-up and are often left running when not in use. Using power down, sleep, hibernate and standby can reduce unnecessary use of natural resources.

Monitor settings

Many monitors allow users to alter settings to save energy. Some advice around energy use is:

  • reduce the 'brightness' setting as much as possible
  • activate efficiency mode if the monitor supports this setting
  • do not use a screen saver
  • use energy efficient monitors:
    • often marked with the energy star sticker
    • these include energy efficiency modes eg brightness automatically reduced when not in use
