According to EDF Particulier, a refrigerator that runs continuously can consume up to 332.30 kWh of electricity per year. This figure can vary significantly based on daily habits, proper settings, and regular maintenance. Since refrigerators are usually plugged in around the clock to keep food cool, they have a noticeable impact on household electricity bills. On average, EDF Particulier reports that refrigerators use about 332.30 kWh annually, as they operate nonstop. However, factors like incorrect temperature settings, doors left open for long periods, or the buildup of frost can increase energy use and, consequently, electricity costs. The good news is that reducing a refrigerator’s energy consumption can be achieved by adjusting its settings, changing daily habits, and performing regular maintenance. EDF Particulier and UFC-Que Choisir, a French consumer rights organization, suggest setting the refrigerator to around 4–5°C and the freezer to -18°C to keep food fresh while minimizing energy use. They note that for every degree below these recommended temperatures, energy consumption increases by about 5%. Additionally, a frost layer of just 3 mm can lead to nearly a 30% rise in energy use. Controlling energy consumption starts with adjusting the thermostat. UFC-Que Choisir recommends keeping the refrigerator’s central area at 4–5°C and the freezer at -18°C. These temperatures help preserve food while limiting electricity use. A simple way to check if your refrigerator is within the correct range is to place a thermometer on a shelf for a few hours. On many models, the thermostat uses numbers instead of degrees, which can be confusing. EDF advises starting at the middle of the scale, waiting 24 hours, and then adjusting if necessary. To optimize energy use, it’s better to use the fresh compartment and the vegetable drawer, which are naturally colder, for sensitive foods rather than lowering the temperature of the entire refrigerator. Another key tip is to let dishes cool down before placing them in the refrigerator, as warm food can cause the appliance to work harder. Additionally, being mindful of how often the refrigerator door is opened and how it is used can help reduce energy consumption. Every time the door is opened, warm air enters, forcing the refrigerator to use more energy to cool down again.
