Reducing the energy consumption of your refrigerator

Energy savings start with simple changes in our daily lives: turning off the light, not leaving the water faucet run, taking a shower instead of a bath… But it also involves the optimization of our appliances! We will look at a vital member of each household: the refrigerator. How can you reduce the energy consumption of your refrigerator?

Here are a few tips:


1- Use a LED light bulb


You may not know it, but those LED light bulbs that make you save energy throughout your home can also be used in the refrigerator! While they initially cost more, they consume less than standard bulbs and have a longer life.


2 – Don’t leave the door open


According to the Institute of Food and Agricultural Sciences at the University of Florida , the bad habit of leaving the refrigerator door open for too long can produce energy waste varying from 50 to 120kWh per year. To better understand this energy loss, 100kWh represents approximately 50 washing machine cycles!

As a matter of fact, leaving the door open will replace the cold air that keeps food at the right temperature with ambient air that will heat up the inside of the appliance. To lower the temperature once again, the appliance’s compressor will kick in, consuming energy until the temperature has dropped down again.


3- Dust the cooling coils


Cooling coils, (located at the back of the refrigerator) are designed to facilitate the evacuation of excess heat out of the refrigerator. When these coils are clogged, the generated heat remains trapped and returns in the refrigerator, forcing the compressor to consume more energy to maintain a low temperature.

Cleaning the coils on a regular basis is a simple gesture you can adopt to allow excess heat to evacuate and consequently save energy.


4 – Simple rules to follow before putting leftovers in the refrigerator


In the spirit of avoiding unnecessary temperature increase inside the refrigerator, wait until your leftovers cool down before placing them in the refrigerator to avoid diffusing the heat inside.

Furthermore, cover leftovers with plastic wrap or store them in Tupperware containers. This helps limiting moisture released from leftover food, which in turn will limit the activity of the compressor.


5- Defrost the freezing compartment


Ice acts like an insulation between the indoor air and the refrigeration system. When ice builds up in the freezer, the appliance uses more energy to maintain the proper temperature (-18°C, or 0ºF).

Failing to defrost your freezer on a regular basis will expose you to not only a higher consumption of energy, but also the risk of losing food that would be otherwise poorly preserved.
