With rising energy prices, it is understandable that people are looking for ways to reduce their electricity bills. One way to do this is by understanding how much energy each device in your home consumes. This can be done through the use of a home energy monitor, such as Wiser Energy, which breaks down energy usage at the device level. Modern refrigerators are highly efficient in electricity use, so the savings from unplugging them will be negligible. However, there are still ways to save money on electricity related to your refrigerator. For example, you can save energy by opening the fridge less often during the day. Additionally, the age of your refrigerator, where it is located in your home, and how much food you store can all affect the amount of electricity it consumes.
| Characteristics | Values |
|---|---|
| Replacing an old refrigerator with a new ENERGY STAR certified model | Energy savings will vary based on use, upkeep, and other factors |
| Using a mini-fridge instead of a full-sized refrigerator | May reduce electricity bill, but may not be worth the cost of buying a new fridge |
| Turning off the refrigerator for a few hours each day | Likely to increase electricity costs as it takes more energy to cool something warm than to keep something cool; may also cause foodborne illness |
| Opening the fridge less often | Can save energy by allowing the fridge to maintain a constant temperature |
| Cleaning the coils in the back of the fridge | May reduce electricity costs |
| Checking your electricity bill for fixed charges and surcharges | May be able to take advantage of discounts for low-income individuals |

Modern fridges are efficient, so savings from turning off may be negligible
Modern fridges are highly energy-efficient, so savings from turning them off may be negligible. Firstly, it is important to note that refrigerators today use about 3.5 times less energy than models from the 1970s. They have better insulation, sealing around the doors, and more efficient compressor motors. Advanced adaptive compressors, recognised by the EPA with the 2020 ENERGY STAR Emerging Technology Award, have led to a big increase in energy savings.
The savings from turning off a modern fridge may be negligible because, as a basic scientific principle, it takes more energy to cool something down than it does to keep it cool. Therefore, turning off your fridge for a couple of hours a day or during the night will likely result in higher energy usage as the fridge will have to work harder to cool down to the set temperature once it is switched back on. This may also put a strain on the compressor.
Additionally, modern fridges have innovative features that further minimise energy consumption and maximise performance. These include LED lights, which consume significantly less energy and produce minimal heat, reducing the burden on the cooling system. Temperature sensors prevent unnecessary cooling cycles, adaptive defrost systems monitor frost build-up and only defrost when necessary, and energy-saving modes adjust the fridge's operation during off-peak hours or when the appliance is not in active use.
Instead of turning off your fridge, you can save money on your electricity bill by paying attention to other areas of electricity usage, such as unplugging devices that are always on or instant-on, like TVs and computers. You can also open the fridge less often during the day, as this will save more energy than turning it off for a couple of hours.

Opening the fridge less often saves more energy than turning it off
It is more energy-efficient to open the refrigerator less often than to turn it off. Modern refrigerators are designed to be highly energy-efficient, with features such as insulation and thermostat-controlled cooling. While turning off the fridge for a couple of hours each day may seem like a good idea, it can actually use more energy. This is because it requires more energy to cool down a warm refrigerator than it does to maintain a constant cool temperature.
Repeatedly turning the refrigerator on and off can also put a strain on the compressor, potentially reducing its lifespan. Additionally, keeping the fridge constantly cool helps to preserve food and prevent the growth of bacteria. Therefore, it is more beneficial to focus on reducing the number of times the fridge door is opened, as this will help maintain a constant temperature and reduce energy usage.
One way to achieve this is to plan meals and prepare snacks in advance, so that you can quickly access what you need without having to browse. Keeping the fridge well-stocked also helps, as the thermal mass of the items inside contributes to maintaining a stable temperature. Regularly cleaning the coils at the back of the fridge can also improve its energy efficiency.
For those wishing to take a more technical approach, devices such as a Kill-A-Watt can be used to measure energy consumption and identify areas where improvements can be made. Some people even build their own controllers/timers to automate the powering off of the fridge during specific times, such as peak energy hours. However, this approach may not always result in significant savings, and the potential impact on food quality and compressor health should be carefully considered.
In conclusion, while turning off the refrigerator for short periods may save money, it is not the most effective way to reduce energy usage. A better approach is to focus on keeping the fridge well-maintained and stocked, and to minimise the frequency of door openings, thereby maintaining a constant, energy-efficient temperature.

Use a home energy monitor to see how much energy your fridge consumes
If you're looking to reduce your electricity bill, it's worth considering a home energy monitor. These devices are small and are installed in the circuit breaker panel of a house or apartment. They can measure how much electricity your home uses, down to individual circuits and even single devices, allowing you to identify ways to save.
Home energy monitors allow you to monitor your energy use and view your energy costs in real-time. They can help you identify appliances that are using a lot of energy and wasting electricity. For example, you may discover that your refrigerator and AC account for 40% of your energy usage, as one user of Emporia Vue 3 Home Energy Monitor did.
Some home energy monitors also allow you to track the cost of your energy consumption in real-time. You'll be able to see and understand the effects of turning devices on and off. For example, you may notice that keeping your TV on in the background increases your electricity consumption and costs.
It's important to note that not all monitors have the same features, and the technology doesn't always work perfectly. Devices that use electricity similarly (e.g., heating devices like a toaster and a curling iron) may be challenging for the monitor to differentiate.
Additionally, while these monitors can provide valuable insights, they don't reduce your bills by themselves. It's up to you to make and stick with the behavioural changes suggested by the monitor to see a decrease in your electricity bill.

Fridge rebates may be available for ENERGY STAR-certified models
If you're looking to save money on your electricity bill, investing in an energy-efficient refrigerator is a great idea. ENERGY STAR-certified refrigerators are around 9% more energy-efficient than models that meet the federal minimum standard, and they can be up to 20% more efficient. This means you'll be using less energy overall, which will reduce your electricity costs.
One way to make this upgrade even more affordable is to take advantage of fridge rebates. These rebates are offered by partners of the ENERGY STAR program and can help offset the cost of purchasing a new, energy-efficient refrigerator. To find rebates and special offers near you, simply use the Product Rebate Finder on the ENERGY STAR website. Just enter your zip code, and you'll be able to see what rebates are available in your area.
When choosing an ENERGY STAR-certified refrigerator, there are a few things to keep in mind to maximize your energy savings. Firstly, consider the size of the refrigerator. Generally, larger refrigerators consume more energy, so opt for a model that's appropriately sized for your needs. The most energy-efficient models tend to be around 16-20 cubic feet. Additionally, consider the type of refrigerant used. Select a model with a lower Global Warming Potential (GWP) refrigerant, such as R-600a or R-441A. These refrigerants have a much lower impact on the climate if they're released into the environment.
By combining the use of rebates with the purchase of an energy-efficient model, you can significantly reduce the cost of upgrading your refrigerator while also lowering your electricity bills and helping the environment.
