Which appliances are the most energy efficient in Australia?
When it comes to managing your household energy usage, every watt counts. From the fridge humming in the background to the washing machine spinning your laundry, your appliances play a major role in both your power bill and your environmental footprint.
But which appliances are doing the heavy lifting efficiently - and which ones are sneakily guzzling electricity? Let’s break down energy efficiency in a way that’s informative, helpful, and maybe even a little fun.
Does energy efficiency matter?
Absolutely and here’s why.
Energy efficiency isn't just a buzzword. It’s about using less power to do the same job, whether that's heating your dinner or cooling your home. Energy-efficient appliances are designed to consume less electricity, saving you money and reducing strain on the energy grid.
In Australia, household appliances account for approximately 30–40% of total residential electricity use, depending on climate and usage habits. Choosing energy-efficient models can help cut your electricity bill significantly - and support the country’s broader push for net-zero emissions by 2050.
Why should I buy energy efficient appliances?
Lower running costs
Energy-efficient appliances often cost more upfront, but the savings on your electricity bill over time are worth it. For example, a 5-star fridge might save you $200–$400 over its lifetime compared to a 2-star model.
Environmental benefits
Using less electricity helps lower greenhouse gas emissions, especially if your energy comes from fossil fuels.
Better performance
Newer, more efficient models often come with improved technology and smarter features.
Government incentives
In many states, you may be eligible for rebates or discounts for choosing efficient products.
So not only do you save money, but you also get more bang for your buck and do your bit for the planet.
Which appliances are the most energy efficient?
Here’s where it gets interesting. Some appliances are naturally more efficient than others, but much of it comes down to how often you use them and how they’re designed. Below is a general ranking of household appliances - from most to least energy efficient - and why they fall where they do.
🥇 Most efficient to least efficient (typical usage)
| Appliance | Efficiency rating | Why? |
| LED lights | ⭐⭐⭐⭐⭐ | Use up to 85% less energy than incandescent bulbs. Long lifespan, low heat output. |
| Heat pump hot water systems | ⭐⭐⭐⭐ | Use ambient air to heat water, consuming 60–70% less energy than electric storage systems. |
| Front-load washing machines | ⭐⭐⭐⭐ | Use less water and energy per wash than top-loaders. Often have eco-cycles and cold wash options. |
| Refrigerators (with inverter tech) | ⭐⭐⭐ | Inverter motors adjust cooling based on usage. 5-star models use ~30% less energy than 3-star ones. |
| Reverse cycle air conditioners | ⭐⭐⭐ | Efficient for both heating and cooling, especially with smart thermostat controls. |
| Dishwashers | ⭐⭐ | Modern models are water and energy efficient, especially when used with eco settings. |
| Dryers | ⭐ | One of the least efficient, especially vented dryers. Heat pump dryers are better, but still high energy users. |
| Electric ovens and stovetops | ⭐ | Consume a lot of electricity, especially if used frequently or for long periods. Induction models are more efficient than ceramic or coil. |
Key takeaway: Appliances that run constantly (like fridges) or generate heat (like dryers or ovens) have the most significant impact on your energy bill. Efficient models make a big difference here.
How do I find the most energy efficient appliances?
In Australia, appliance efficiency is clearly labelled - if you know where to look.
Energy rating labels
The star rating label is your first port of call. Appliances are rated from 1 to 10 stars (with 6 being the standard max, and 10 stars for super-efficient models). More stars = lower energy use.
The label also shows annual energy consumption in kWh, which helps estimate running costs.
Tip: Two similar products with the same star rating can still differ in kWh usage. Always compare both.
Look for inverter technology
Appliances with inverter motors (common in air cons, fridges and washing machines) adjust power use depending on the task - saving energy compared to traditional on/off systems.
Check the size and capacity
Don’t overbuy! A massive fridge or washer uses more energy than needed for a two-person household. Choose size based on your real needs.
How to save money on running household appliances
Buying efficient appliances is step one. Using them smartly is step two.
Here are some practical tips to keep your bills down:
🔌 Unplug or switch off appliances at the wall: Many devices draw “phantom power” even when not in use.
🌡️ Set thermostats wisely: In winter, aim for 18–20°C. In summer, 24–26°C is ideal. Every degree above or below adds ~10% to your heating/cooling cost.
🧺 Wash with cold water: Up to 80% of a washing machine's energy goes into heating water. Cold washes = big savings.
🕓 Use timers or off-peak power: Run dishwashers and washing machines during off-peak times if your plan supports it.
🧼 Clean filters and seals: Regularly clean your air con filters, fridge seals, and dryer lint traps to maintain efficiency.
💡 Switch to LED bulbs: If you haven’t already, LED lighting is the easiest and cheapest upgrade you can make.
