A Guide to Energy-Efficient Fridges
14th February 2025
Buying and maintenance guide for energy-efficient fridges.
Fridges are among the most important appliances in our homes, keeping our food fresh and our plates full. But if we’re not careful, they can end up consuming far more energy than necessary, which can result in higher than anticipated electricity bills. Opting for an energy-efficient fridge can not only save you money, but may also help reduce your environmental impact. In this guide, we'll explore how to choose the best energy-efficient fridge for your home and offer tips to reduce your everyday energy consumption.
What is an energy-efficient fridge and why does it matter?
An energy-efficient fridge is one that is designed to consume minimal amounts of energy while maintaining optimal performance. These fridges are often identified by their energy-star ratings, which indicate their efficiency level. A higher star rating means the fridge uses less energy, resulting in lower running costs and electricity bills. Typically, fridges display up to six stars, but some advanced models feature an additional four-star crown above the standard star band, signifying exceptional efficiency.
While energy-efficient fridges may have a higher initial cost compared to less efficient, older models, the investment usually pays off over time through lower electricity bills.
Is my fridge energy efficient?
The easiest way to answer this question is by checking the Energy Star Rating. If the rating is below three stars, it may be time to consider upgrading to a newer, more energy-efficient model.

How much power does a fridge use?
The electricity price fluctuates over time and differs depending on where you live. To help consumers understand the potential running costs of fridges, labels state annual kilowatt hours (kWh) – representing what your fridge will use per year based on Australia’s average consumption. You can calculate the cost of running your fridge by multiplying the kWh by your local electricity price.
Example calculation:
For example, the fridge states it consumes 600kWh per annum and your electricity price is 28 cents per kWh, multiplying the two numbers together reveals that the fridge costs $168 per year (or $14 per month) to run.
Given that fridges typically last for many years, investing in an energy-efficient fridge can yield significant savings in the long run.
Buying tips for energy-efficient fridges
Choosing an energy-efficient fridge is key to saving both energy and money in your home in the long run. Here are some practical tips to guide your selection:
Size and capacity:
Consider your household's needs when picking a fridge size. Opt for a smaller model if possible, as larger fridges tend to use more energy. A smaller fridge that still meets your needs can lead to significant energy and cost savings.
Features to look for:
Focus on features that boost efficiency. The best combo is a stacked fridge/freezer with the freezer on top. Look for handy extras like open door alarms and easy thermostat controls. Be cautious with energy-intensive features like ice makers and door dispensers. And make sure the fridge seals tightly to keep cool air in.
Understanding Energy Star Ratings:
Look at the ratings on similar sized fridges. More stars means more efficiency and lower costs and energy consumption.
How best to operate a fridge to lower energy use
Whether you’ve just bought a new fridge or you’re looking for ways to improve the efficiency of your existing one, you can follow these handy tips to help lower your energy consumption:
- Buy a fridge that suits your needs: A bigger fridge uses more energy and occupies more space.
- Proper placement: Place your fridge away from direct sunlight, windows, and heat-generating appliances to reduce its workload and improve efficiency.
- Ensure proper ventilation: Make sure you have space around your fridge for ventilation.
- Clean the coils: Regularly clean the coils to remove dust and debris, preventing your fridge from working harder and consuming more energy.
- Check your door seals: Inspect door seals regularly to ensure they form a tight seal, preventing energy wastage from air leaks.
- Avoid opening the door unnecessarily: Avoid unnecessary openings to prevent cool air from escaping and reduce the workload on your fridge's cooling system.
- Allow food to cool before refrigerating: Let hot or warm food cool to room temperature before refrigerating to maintain a consistent internal temperature.
- Holiday preparation: When you’re going away for an extended period, it’s a good idea to empty your fridge of perishable items, switch it off, and leave the door open to prevent mould and odours.
The final word
When you purchase a new fridge, choose an energy-efficient model. This decision can reduce your energy consumption and your electricity bill. With an energy-efficient fridge, you won’t compromise on quality and features to keep your energy costs low.
