Tips on saving energy from your refrigerator

by Peter on March 25, 2012

Your refrigerator is one of the appliances at home that consumes a significant amount of electricity since is probably the only one that works 24 hours a day.  It is estimated that in a household the refrigerator consumption of electricity can be up to 14% of its total, ranking it second behind heating and cooling. Below is a list with useful information on your refrigerator energy consumption and ways to cut it back:

  1. If you are buying a new refrigerator make sure that it has a low level of consumption. If you are in the States this means that it has to be an energy star model and if you are in Europe this translates into being an A class consumption appliance.
  1. Make sure that you place your refrigerator away from any heating source such a cooking stove or heating elements and in addition make sure that there is no direct sunlight in the area you are placing it otherwise your consumption might get increased by 30%.
  2. Set the fridge at a temperature between 36F to 45 F (3-7 c) and the freezer to -5F (-17 c) and save up to 20% energy for every additional 10 degrees for the fridge or 5 degrees for the freezer.
  3. Do not open the fridge door frequently or keep the door open for a long period of time. Moreover make sure that the door seal is clean and fits perfectly on both the fridge and the freezer.
  4. Do not cover the ventilation points of the device and make sure that for the back you leave a two inches empty space (also it is preferable to use an external wall.)
  5. Don’t place any hot food inside the fridge since it will have to use energy to adjust its temperature. Furthermore, when you want to thaw food from the freezer place it in the fridge from the previous night this way you save energy during defrosting.
