How much power does a refrigerator use?

power, energy efficient,

In the late nineteenth century, refrigerators revolutionized food preservation and are now present in almost every Western household. The equipment to household rate in France in 2011 was an estimated 99.8% and nearly 2 million refrigerators are sold each year, according to the GIFAM (French Inter-branch Group for Household Appliance Manufacturers). Refrigerators, generating continuous cold, are often considered some of the most energy-intensive appliances. Let’s take a closer look at this statement.


More energy-efficient and environment-friendly recent models

Although average French households own more and more high-tech equipment (internet set-top boxes, flat-screen TVs), refrigerators and freezers still account for a third of their energy bills (excluding heating), followed by dishwashers and tumble dryers (14%), audiovisual equipment (12%) and washing machines (7%).

Refrigerators over 10 years old use a lot of electricity and can be polluting if they contain chlorofluorocarbons (CFCs), a chemical that has been banned since the 2000s. According to the ADEME, the French Environment and Energy Management Agency, a new fridge with an A++ rating on its energy label uses up to 60% less electricity than a ten-year-old fridge with a C rating.

A simple calculation shows the increasing energy efficiency of new-generation equipment. All things being equal (290-liter capacity, electricity price of 0.121 € per hour), an A++ rated refrigerator uses 213 kWh every year while an A-rated fridge needs 349 kWh. The savings are worth 160€ per year, that is 1,600 € in ten years.

However, it is important to mention that the energy label is awarded based on an energy use to capacity ratio. That is why a super size “American fridge” can get an A rating although it uses twice more energy than an A-rated “conventional” fridge! Therefore, comparisons based on energy labels are only relevant between products similar in size and functions.

Little tricks to make your fridge more energy efficient

The unit’s location matters. Near a heat source or too close to a wall (less than 5 cm), it will put more stress on the engine to offset the heat, thus using more electricity. Similarly, placing warm food into the refrigerator will raise the inside temperature, forcing it to work harder to maintain the desired temperature.

A refrigerator requires maintenance. It is important to ensure regular defrosting to prevent frost from building up and causing the fridge to use more electricity. Besides, door gaskets must be inspected, as worn seals can cause energy use to rise by up to 20%.
