What You'll Learn
Use power-saving mode
Using a refrigerator's power-saving mode is an effective way to reduce electricity consumption at home. Power-saving modes, such as those offered by LG refrigerators, allow you to optimise energy usage based on your needs. For example, you can activate an eco-friendly mode when you're away or during non-peak usage hours. This feature is especially useful in hot climates, where energy conservation is crucial.
Some refrigerators with power-saving modes use inverter compressors, which adjust their speed according to the cooling demand. This technology not only reduces power consumption but also maintains more consistent temperature levels inside the fridge, ensuring food stays fresh.
If your refrigerator has a power saver mode or vacation mode, it is beneficial to use it, especially when there isn't much food inside that needs to be kept cool. This will reduce energy consumption and extend the lifespan of your appliance.
Additionally, when leaving your home for an extended period during the summer, it is recommended to set your thermostat to a high temperature, such as 85 degrees Fahrenheit. This is because your refrigerator works much harder to maintain cool temperatures in a room with a high ambient air temperature.
While some sources suggest turning off the refrigerator for a few hours each day may save energy, others argue that it may not significantly impact your electricity bill. Modern refrigerators are highly efficient in electricity use, and the savings from a few hours of turning it off may be negligible. Furthermore, the refrigerator will use more electricity to cool down again after being turned off, and there are potential food safety concerns as well.
Therefore, instead of turning off the refrigerator, using a power-saving mode can be a more effective strategy to reduce electricity consumption without compromising food safety or incurring high costs associated with cooling the refrigerator back down.

Clean the coils
To save electricity at home, it is important to clean the coils of your refrigerator at least once a year. This is because the refrigerator compressor is one of the bigger sources of power consumption in your home. When the coils are clogged with dust, the compressor has to turn on more frequently and work harder, leading to increased power consumption and a higher electric bill.
To clean the coils, first unplug the refrigerator to reduce the risk of electrical mishaps. Then, remove the front and/or back panel to access the coils. On older or smaller fridges, the coils may cover the entire back of the fridge and can be accessed by removing the back panel with a handful of screws.
Once the coils are accessible, use a vacuum hose or a "coil brush" from a hardware store to gently clean the coils. Be careful not to apply too much direct pressure to avoid bending the coils. Alternatively, you can use a leaf blower or a box fan with a spare AC filter attached to reach the coils and blow away the dust.
By cleaning the coils regularly, you can improve your refrigerator's efficiency and extend its lifespan, saving you money on your power bill in the long run.

Keep the fridge organised
Keeping your fridge organised is a great way to save electricity. It might seem like a simple housekeeping task, but it can make a big difference to your energy consumption.
Firstly, keeping your fridge well-organised means you will spend less time rummaging around for food with the door open. This is important because the longer the door is open, the more cool air escapes and the more the internal temperature rises. As a result, the fridge has to work harder to cool down again, using more energy.
Secondly, good organisation ensures that air can circulate freely within the fridge. This prevents overcooling and helps maintain a consistent temperature. When air cannot circulate properly, certain areas of the fridge may become too cold, causing the compressor to work harder to maintain the set temperature.
To keep your fridge organised, ensure that food items are not blocking vents or air circulation points. Store items in a way that maximises space and allows cool air to move freely. Use clear, labelled containers to make it easy to find what you need quickly. You can also group similar items together to reduce the time spent searching.
By keeping your fridge organised, you can help it run more efficiently, saving energy and money on your utility bills.

Maintain ventilation
Maintaining good ventilation and airflow in your refrigerator is essential to its performance and energy efficiency. Here are some tips to ensure your refrigerator is properly ventilated:
Firstly, ensure there is adequate space around the appliance for ventilation. Allow for at least 5 cm of free space on the sides, back, and top of your refrigerator. This space is crucial as it allows the appliance to release heat from the compressor. Without this air gap, the fridge will heat up and work harder and longer to maintain the desired temperature, resulting in increased energy consumption.
Next, locate the air vents in your refrigerator and freezer compartments. These vents facilitate the flow of cool air between the two compartments. Ensure that these vents are not blocked, as this will hinder airflow and lead to temperature and moisture issues. Regularly check and maintain the vents to promote optimal airflow and even cooling throughout the unit.
Additionally, the arrangement of items inside your refrigerator can impact airflow and temperature retention. A well-filled refrigerator helps maintain cold temperatures. If your fridge is not sufficiently stocked, a simple solution is to place jugs of water on the shelves. These act as "cold batteries," optimizing airflow and chill.
Finally, it is important to clean the condenser coils, as these play a vital role in the refrigeration process. At least once a year, be sure to unplug the unit and carefully clean the coils by brushing or vacuuming them. This can significantly improve the efficiency of your refrigerator by promoting better airflow and heat exchange.
By following these ventilation and airflow tips, you can enhance the performance and energy efficiency of your refrigerator, while also extending its lifespan.

Upgrade to an energy-efficient model
If you're looking to save electricity at home, upgrading to an energy-efficient refrigerator model is a great idea. Older refrigerators can be costly to run, with those over 15 years old potentially costing upwards of $80 per year to run.
When shopping for a new, energy-efficient refrigerator, there are several things to keep in mind. Firstly, pay attention to the size of the refrigerator. Generally, the larger the refrigerator, the greater the energy consumption. The most energy-efficient models typically have a capacity of 16-20 cubic feet.
Secondly, consider the type of refrigerator. Frost-free, freezer-top, and freezer-bottom models are generally more energy-efficient than multi-door models. Refrigerators with the freezer on top tend to use the least energy compared to bottom freezers or side-by-side models. This is because side-by-side models have more external surface area that gets warm, and bottom freezers often have energy-hungry add-ons like an in-fridge ice maker. Therefore, opting for a model with fewer doors can help reduce air leakage, which in turn improves energy efficiency.
Additionally, look for models with features that improve energy efficiency. For example, some refrigerators have a power-saving mode or vacation mode, which can be useful when the fridge is not fully stocked. You can also select a refrigerator with a lower Global Warming Potential (GWP) refrigerant. Refrigerants with lower GWP, such as R-600a and R-441A, have a reduced impact on the climate if they are released into the environment.
Lastly, consider purchasing an ENERGY STAR certified refrigerator. These models are designed to save energy and can be up to 20% more efficient than models that meet the federal minimum energy efficiency standard. They deliver cutting-edge energy efficiency along with the latest technological innovations, so you can be sure your new refrigerator is working smarter, not harder.
