In nearly every household, the refrigerator runs 24/7—keeping food fresh, safe, and accessible. But what many people don’t realize is that one small, often ignored setting inside the fridge may be costing them far more on their electricity bills than they think.

While we’re always hunting for energy-saving tips, few mention this simple habit that could lead to noticeable savings—especially during the colder months.

The Hidden Culprit: Your Temperature Dial

Most refrigerators come with an adjustable temperature dial ranging from level 1 to 5 or 1 to 6. During hot summers, it’s common to crank it up to the max. But here’s the secret: in winter, when the ambient temperature is naturally cooler, you likely don’t need your fridge running at full power.

Reducing your refrigerator’s setting to level 2 or 3—or even level 1—in cold seasons can still keep your food safely chilled at a temperature between 2°C and 5°C, while significantly lowering energy use. The same logic applies to the freezer section, which can also be adjusted based on the volume and type of food being stored.

Tailor Settings to Match Food Storage

Besides weather, the amount of food in your fridge should influence the temperature setting. If the fridge is half-empty, it doesn’t need to work as hard to maintain a cold environment. Lowering the setting in this case prevents energy waste.

Conversely, if your freezer is stocked with meats or seafood, maintaining it at around -18°C helps preserve freshness and inhibit bacterial growth—without freezing more than necessary.

Extra Ways to Cut Fridge Energy Use

Optimizing your fridge’s temperature setting is just one part of the puzzle. Experts recommend a few additional practices to maximize efficiency:

1. Strategic Placement

Avoid placing your fridge near heat sources like stoves, ovens, or direct sunlight. Ensure the back and sides have enough clearance from walls to let hot air dissipate. Poor ventilation forces the compressor to work overtime, draining more electricity.

2. Don’t Keep the Door Open

Every second the fridge door stays open allows cold air to escape. The compressor then has to work harder to restore the temperature, consuming more power. Always close the door promptly after use.

3. Use Glass or Ceramic Containers

Glass and ceramic retain cold better than plastic, helping the fridge maintain its internal temperature. Additionally, neatly organizing food improves air circulation, meaning the appliance doesn’t have to work as hard to cool contents evenly.

4. Clean Vents and Coils Regularly

Dust and grime clogging up the vents or coils can drastically affect performance. Wipe down your fridge at least every three months to keep it running efficiently and prevent unnecessary energy use.

Final Thoughts: Small Habit, Big Impact

Reducing your electricity bill doesn't always require major changes—sometimes, it’s as simple as tweaking a dial. Adjusting your refrigerator’s settings in winter, maintaining it regularly, and storing food thoughtfully are all minor habits that, together, can lead to substantial long-term savings.

In an age where energy efficiency matters more than ever—for both your wallet and the environment—it’s time to look inside your fridge and take control of one of the most overlooked sources of energy consumption in your home.
