Did you KNOW!


  • Electric items on standby mode use approx. 30% of energy of when they are in full use.
  • Every time you open the refrigerator door, up to 30 percent of the cold air can escape.


List of tips for reducing energy consumption & GHG emissions:

  • Turn off unnecessary lights when daylight is sufficient or when room is not in use, on a safety note please don't leave your colleagues in the dark!

  • Turn off computer monitors, printers and other peripherals when not in use. Turning off lights and equipment when leaving a room even for ten minutes can make a significant energy saving

  • When experiments are finished turn off power to all ancillary equipment checking first whether equipment can be safely switched off when not in use

  • Check energy rating when purchasing electrical equipment, fridges, dishwashers etc. (A is best)

  • Leave fridge door open for shortest period possible

  • Operate dishwashers/washing machines only when full

  • Fill kettles only to level required when boiling

  • Use the stairs rather than lifts - good for the environment, good for your health!

  • Disconnect unused equipment from mains supply

  • Use heaters/air conditioners/fans etc. only when necessary

  • Don't cover radiators when in use
  • Use thermostats on radiators or radiator valves to regulate your office/home heating


  • Much energy and water using equipment is within the partial or full local control of staff or students. They can actively assist in efforts to reduce energy consumption by greater energy awareness.
  • Simple measures such as ensuring equipment is turned off when not in use or spaces not occupied can yield real and substantive reductions in energy consumption.
  • The Green Campus Committee and work via the inter-university Energy Conservation project will help increase awareness and reduce energy consumption.

  • TCD works with UCD, DCU and DIT on a collaborative energy conservation project called e3 ( standing for Energy, Environment and Economy.
