Energy Facts for the Kitchen / Canteen

Dishwasher

  • Using the dishwasher once will use the same amount of energy as boiling 7.5 full kettles.
  • Avoiding one dishwasher load saves enough energy to power a 100W light bulb for 11 hours.

Kettle

  • If everyone boiled only the water they needed to make a cup of tea instead of filling the kettle every time, we could save enough electricity in a year to run nearly half of the street lighting in the country.

Cooking

  • Microwaves use up to two-thirds less electricity than conventional electric ovens and are useful for reheating meals.
  • By cooking food at a higher temperature and pressure (i.e. in pressure cookers) cooking time is reduced and energy use is typically reduced by 50-75%.
  • Using the toaster to make toast instead of the grill is 3.5 times more energy efficient.

Fridges & Freezers

In one year, an American-style fridge freezer uses 30% more energy than a regular fridge freezer or the equivalent of running a small fan continuously for the entire year. 

  • Defrost fridges and freezers regularly.
  • Make sure to keep the fridge door shut.
  • Keep freezers fairly full (even using empty boxes to fill spaces when gaps appear on the shelves).
  • Choosing an A++ combined fridge/freezer instead of a B-labelled one annually saves the environment 175 kilos of CO2, and about €46 on your annual electricity bill. 

Energy Ratings

  • A-rated appliances can use up to 50% less energy than G-rated appliances. 
  • It is now possible to be selective when purchasing certain new appliances. By taking note of the energy label when making your purchase, you can choose products which have a lighter operating efficiency, saving you money on fuel bills.
