Ways to save electricity

General advice (Nielsen and Dyck-Madsen 2006)

  • switch to energy efficient luminescent lightbulbs
  • check the timer on your circulation pump - alternatively, replace with an energy-efficient pump
  • check that all appliances are completely turned off - especially chargers
  • turn on only appliances in use
  • purchase the most efficient appliances

Advice on lighting (Jacobsen 2002)

  • switch off unnecessary lighting. Install timers and light and motion sensitive equipment.
  • paint walls and ceiling with light colours. Also reduces discomfort from glare and light trespass.
  • Choose the correct lighting. Use appropriate workplace lighting.
  • Use halogen lighting for impact lighting, rather than area/flood lighting.
  • Use high-frequency flourescent lighting, "HF". They have longer lifetimes and reduced flickering.
  • Exploit daylight using automatic light sensitive monitoring.
  • Regular maintenance.

Standby advice (Jacobsen 2002)

  • Turn off all equipment when not in use.
  • Install automatic slumber mode where possible.
  • Turn off screens when absent for longer periods.
  • Purchase appliances marked with "Energy Star" or equivalent.
  • Choose flatscreens.
