A refrigerator runs 24/7, continuously consuming electricity. That’s why choosing an energy-efficient model is crucial to avoid wasting power.

However, not all refrigerators operate efficiently—some consume excessive electricity, leading to higher energy bills.

According to PT PLN (Persero), Indonesia’s electricity sales in the first half of 2024 reached 149.11 Terawatt Hours (TWh), marking a 7.54% increase compared to the same period in 2023. This growth was mainly driven by rising electricity consumption in the business sector (10.54%) and households (8.75%), showing that household electricity use—including refrigerators—continues to rise.

Therefore, you should recognize when a refrigerator wastes electricity. This way, you can use the refrigerator more wisely and save electricity at home. So, what are the characteristics of an electricity-consuming refrigerator? Read on to find out!

When Does a Refrigerator Waste Electricity?

Several things can indicate that your refrigerator is consuming excessive electricity, from unusual noises to dirty cooling coils. Here’s a closer look at the key signs to watch for:

1. Unusual Noise

If your refrigerator makes unusual noises, such as buzzing or vibrating, it could be a sign that certain parts work harder than they should.

For instance, the compressor may struggle to maintain the right temperature or other components might not function properly. If left unchecked, this can lead to higher energy consumption and potentially cause more serious issues down the line.

2. Inconsistent Temperature

When the refrigerator’s temperature fluctuates or certain areas do not cool evenly, it has to work harder to maintain the desired cold temperature. This increased effort leads to higher electricity consumption.

3. Excessive Ice Buildup

A large buildup of ice inside the freezer or around the refrigerator coil can block proper airflow. As a result, the refrigerator has to work harder to maintain the right temperature, leading to excessive electricity consumption and energy waste.

4. Dirty Cooling Coil

Dust-covered or dirty cooling coils can cause the refrigerator to struggle to release heat efficiently. As a result, it has to work harder to maintain the desired temperature, leading to increased electricity consumption.

5. Overstuffed or Nearly Empty Refrigerator

An overstuffed and nearly empty refrigerator can lead to excessive electricity use. When the fridge is overloaded, cold air struggles to circulate properly, making it harder to maintain a consistent temperature.

On the other hand, a nearly empty refrigerator has to work harder to keep the internal temperature stable. In both cases, energy consumption increases, leading to unnecessary electricity waste.

6. Outdated Fridge

Refrigerators that are over 10–15 years old tend to be less energy-efficient than newer models. As they age, their components wear out, causing them to use more electricity than necessary to maintain proper cooling. 

How to Reduce a Refrigerator’s Energy Waste

To prevent your refrigerator from consuming excessive electricity, you can take several simple steps, such as regular cleaning and smart content organization. Here’s a detailed guide on how to improve your refrigerator’s energy efficiency:

1. Clean the Refrigerator Regularly

To keep your refrigerator running efficiently, regular cleaning is essential. Make sure to get rid of dust, pet hair, or other debris from cooling coils to improve its performance.

Additionally, remove any excess frost buildup inside the freezer to ensure proper air circulation.

2. Place the Refrigerator in the Right Spot

The right position can help your refrigerator reduce its energy consumption. Avoid placing it directly against a wall or near heat-producing appliances, such as ovens or stoves.

Proper placement ensures efficient airflow around the refrigerator, preventing the compressor from overworking and helping to save electricity.

3. Minimize Frequent Opening 

To save electricity, avoid opening the refrigerator too often or leaving the door open for too long. As a solution, consider choosing a refrigerator with an external temperature panel, allowing you to adjust the settings without opening the door.

4. Choose an Energy-Efficient Refrigerator

Upgrading to a newer, energy-efficient model can significantly reduce electricity consumption. Modern refrigerators employ advanced technology, such as inverter compressors, which adjust their workload based on temperature needs, making them more efficient.

Additionally, many newer models come with automatic temperature control and improved insulation, helping maintain a stable temperature without using excessive electricity.

5. Organize Refrigerator Contents Wisely

Instead of overfilling or leaving your refrigerator nearly empty, try to manage its contents efficiently. Regularly check stored food items to ensure freshness and avoid unnecessary waste.

Avoid placing hot food or drinks directly in the refrigerator. Additionally, if you have food that you won’t be able to consume in time, consider repurposing it for compost to reduce waste.

That concludes the explanation of the signs of an energy-wasting refrigerator and how to address them. By understanding these factors, you can use your refrigerator more efficiently, helping to lower electricity bills and reduce unnecessary energy consumption.

Beyond saving electricity at home, the shift toward eco-friendly energy solutions continues to gain momentum. PT Krakatau Chandra Energy, a subsidiary of the Chandra Asri Group, is actively contributing to this initiative.

This effort aligns with the government’s goal of achieving net zero emissions by 2060. As part of its commitment to sustainable energy, PT Krakatau Chandra Energy provides various services, including solar panel installations and the development of electric vehicle (EV) charging stations in Jakarta and Cilegon.

Additionally, you can take part in environmental conservation efforts by joining the Indonesia Asri campaign. This movement encourages real action and environmental education, particularly in responsible waste management.

This initiative reflects Chandra Asri Group’s commitment to environmental preservation. Indonesia Asri also offers a variety of exciting activities and engaging challenges through the #SiPalingSustainable movement.

These challenges allow you to adopt an eco-friendly lifestyle in a fun and simple way—plus, you’ll have the chance to win exciting prizes!
