How to reduce electricity consumption of refrigerator: Expert tips you can start today 

Your refrigerator is always on, but it doesn't have to use a lot of energy. With a few easy adjustments, you can lower your electricity bill without much effort.

In this article, we'll share practical tips on how to save electricity when using refrigerator, from organising your food for better airflow to choosing the right settings. You will also find expert advice on how Electrolux’s energy-efficient technologies work to save you money.

Tips on how to reduce electricity consumption of your refrigerator

Use the right temperature setting

The optimal range is 3°C to 5°C for fridges and -18°C for freezers.

Unsure if your settings are right? This guide on temperature settings explains how to strike the right balance, and since thermostats can be inaccurate, it’s worth using a refrigerator thermometer to double-check.

Keep your refrigerator well-stocked but not overloaded

A well-stocked fridge helps maintain a stable internal temperature because the items inside help retain the cold. But don’t overdo it, overloading blocks airflow, making the system work harder. When organising your items, try to keep airflow channels clear and efficient. 

If your current fridge is frequently packed or you find yourself making extra shopping trips, a larger fridge, like a spacious 500L refrigerator, may solve those pain points without compromising kitchen flow.

Regularly defrost your fridge

When frost builds up beyond 0.6 cm, it starts acting like insulation and makes the compressor run longer. Defrosting your fridge every 6 months, or when frost starts building, keeps things running efficiently. Avoid sharp tools when defrosting your fridge; use warm water and dry everything before switching the fridge back on.

Ensure door gaskets are sealed properly and minimise door openings

Leaky or damaged door seals let cold air escape, meaning your fridge has to work harder. Test them by closing a piece of paper in the door - if it slides out easily, the seal might need replacing. Clean gaskets with warm, soapy water and avoid frequent door openings by planning meals and grouping commonly used items up front.

Position your refrigerator away from heat sources

Keep your refrigerator away from ovens, windows with direct sun, and other heat-producing appliances. External heat makes the fridge work harder to maintain its temperature. Also, ensure there’s enough clearance around the fridge for heat to dissipate effectively.

Avoid using thick refrigerator covers

A heavy fridge cover can trap heat, which makes your compressor run longer. If you must use a cover, choose one designed to allow proper airflow, or better yet, skip the cover altogether.

Stock only needed food items and remove expired ones regularly

Excess or expired food items take up unnecessary space and reduce airflow. Cleaning out unused items regularly not only keeps your fridge organised but also allows it to operate more efficiently.

Seal food tightly before storing

Loose food releases moisture, increasing humidity inside the fridge. This forces the compressor to work harder. Store items in airtight containers or wrap them well to prevent moisture buildup and help your fridge run smoothly.

Avoid placing hot food directly into the refrigerator

When you place hot food in the refrigerator, it increases the internal temperature, which forces the fridge to work harder to cool it down. The compressor runs for longer periods, consuming more energy to bring the temperature back to the desired level.

Allowing food to cool to room temperature before refrigerating helps maintain the fridge's temperature and reduces the energy needed to compensate for the heat.

Clean the refrigerator regularly

The condenser coils are responsible for releasing heat from the fridge, and if they’re covered in dust, it hampers their ability to release that heat efficiently. This forces the compressor to consume more energy to maintain the correct temperature.

Similarly, dirty or damaged door seals prevent the fridge from maintaining a proper seal, causing cold air to escape, which makes the compressor work longer than needed. Regular cleaning ensures that these components function efficiently and helps lower energy use.

Upgrade to energy-efficient refrigerator models

If your refrigerator is more than ten years old, one of the most effective ways to save electricity is by upgrading to a newer model. Modern refrigerators are designed to deliver superior cooling while using significantly less power.

According to Electrolux experts, an energy-efficient refrigerator is defined by its smart technology and performance. “Modern innovations work together to reduce electricity consumption without compromising freshness,” they explain. A standout feature is AI-CoolAssist technology, which can save up to 10% on energy. It intelligently adapts to your daily habits to optimise fridge settings and maintain optimal cooling conditions - whether you are busy adding groceries or away from home. This works alongside inverter technology and specialised features like the moisture-sealing GreenZone drawer to ensure high food preservation quality while significantly reducing your power bill.

When shopping, it's also helpful to understand common myths. Electrolux experts address the concern that efficiency comes at the cost of performance or space. “A common myth is that these models sacrifice cooling performance to save electricity. In reality, we reduce power consumption through innovations like AI-CoolAssist technology, which intelligently adjusts cooling based on your usage patterns. By pairing this with advanced inverter technology, the fridge maintains consistent, optimal storage conditions while actually reducing noise levels.” 

While some buyers may hesitate at the initial cost, our experts note it’s important to consider the long-term savings on electricity bills. They also remind us that user habits, like frequent door openings, still play a role in a fridge’s overall efficiency, even with advanced features.

The real impact: How energy-efficient refrigerators lower your electricity bill?

Reducing your refrigerator’s energy use isn’t just good for the environment; it directly benefits your wallet. As one of the few appliances that runs 24/7, even small inefficiencies can add up to significant energy costs over time.

Refrigerators are one of the largest energy consumers in a household, typically using between 300 and 800 watts of electricity. This translates to an estimated daily consumption of about 4 kWh, or roughly 1,463 kWh per year.

With refrigerators accounting for 18–20% of a home's total electricity usage, reducing their energy consumption can have a noticeable impact on both utility bills and overall energy efficiency. According to experts, households can expect to save between $30 to over $100 annually by switching to an energy-efficient refrigerator, depending on the model and age of the appliance being replaced.

By adopting simple practices like adjusting temperature settings, ensuring proper airflow, and keeping the coils clean, you can noticeably cut your electricity usage. Upgrading to an energy-efficient model can amplify these savings even further.

From smart habits to smarter technology: The future of energy savings

By choosing energy-efficient models and incorporating simple energy-saving habits, you’re not only lowering your electricity bill but also contributing to a more sustainable future.

According to our experts, Inverter technology is a core feature that delivers greater energy efficiency and quieter performance*. The Inverter Compressor automatically adjusts its running speed in response to cooling demand, which maintains an optimal food storage temperature while using significantly less energy**.

For even smarter savings, some models pair this with intelligent systems. As our experts share, “Electrolux refrigerators improve energy efficiency through two key innovations: AI CoolAssist learns your daily habits to optimise fridge settings and Inverter Technology optimises energy efficiency. Together, these technologies help households reduce energy bills, extend appliance lifespan, and enjoy quieter, more reliable refrigeration.”* 

Looking ahead, Electrolux continues to innovate by combining intelligent technology with practical design. Our experts note that the next generation of refrigerators will increasingly use machine learning to enhance energy savings, while improved interior features like flexible compartments and intuitive layouts make food organisation easier. This combination, they explain, "will help households save energy while enjoying a more seamless user experience."
