Appliance ENERGY STAR Ratings Explained
With so many appliances on the market, manufacturers are constantly looking for ways to stand out. One way they're doing this is by offering more energy-efficient models that help homeowners cut down on electricity use, lower energy bills, and contribute to a more sustainable future.
Energy Rating Labels are used in Australia to provide consumers with information about the energy efficiency of appliances. You may also notice ENERGY STAR labels on imported US products.
So, what do they mean, and how can you use this information to pay less on your energy bills and live a greener lifestyle? Here’s what you need to know.
What Are Energy-Efficient Appliances?
Energy-efficient appliances are designed to use less energy while still delivering the same level of performance as standard models. They’re specifically built to reduce energy consumption, help you save on electricity bills and lower your carbon footprint.
These appliances often feature advanced technology or design improvements that optimise power use, like better insulation or more efficient motors.
How much do energy-efficient appliances really save?
The exact amount you can save with energy-efficient appliances depends on the type of appliance, its usage, and the energy efficiency rating. Replacing older, inefficient appliances with models with higher Energy Rating Labels can typically save you anywhere from 10% to 50% on energy costs.
Here are some example savings (figures vary depending on the model and size, and efficiency rating):
- Refrigerators: Save between $50 and $200 per year in energy costs.
- Washing Machines: Save $40 to $100 a year in both electricity and water savings.
- Dishwashers: Can reduce energy costs by $30 to $50 annually.
- Air Conditioners: Offer 15% to 30% energy reduction compared to standard models
Understanding ENERGY STAR and Australian Energy Rating Labels
What ENERGY STAR Means
ENERGY STAR is an international rating system—primarily used in the US—that helps you understand how much energy appliances use. You might see ENERGY STAR-labelled products in Australia, especially if they’ve been imported. These ratings are out of 10 stars, with 1 being the least efficient and 10 the most.
Seeing this label means the product meets strict energy efficiency standards set by a government-approved program.
How Ratings Are Determined
ENERGY STAR ratings are determined by testing appliances in specific conditions to measure their energy consumption. Appliances that use less energy than the average model in their category earn the ENERGY STAR label. The rating takes into account three essential factors:
- Energy use
- Performance
- How much the appliance reduces greenhouse gas emissions
Global vs. Australian Energy Rating Labels
While ENERGY STAR is more common in the US, Australia has its own mandatory Energy Rating Label system. The Australian Energy Rating Label, part of the Equipment Energy Efficiency (E3) Program, rates appliances on a scale of 1 to 6 stars, with higher stars indicating better energy efficiency.
Appliances that go beyond 6 stars may carry a 7 to 10-star label, indicating ‘super efficiency’. For some products, like pool pumps, the 10-star label is now standard.
This labelling system is displayed on a variety of appliances, including:
- Air conditioners
- Fridges and Freezers
- Dishwashers
- TVs
- Dryers
- Clothes washers
- Computer monitors
- Pool pumps
The objective of the energy efficiency label is to help consumers make informed choices based on energy consumption.
What’s the best way to compare appliance energy usage?
To compare appliance energy usage effectively, check the Energy Rating Label, which shows the star rating and an estimate of annual energy consumption. This energy consumption figure helps you gauge how much energy the appliance will use each year. Additionally, dishwashers and washing machines feature a Water Rating Label for water efficiency.
If you require more detailed comparisons, visit the Energy Rating website and use the Energy Rating Calculator to compare specific models and their efficiency.

Key Factors to Consider When Buying Energy-Efficient Appliances in Australia
When shopping for energy-efficient appliances, here are the key factors to keep in mind:
ENERGY STAR Rating Comparison
The first thing you will notice at the top of the label is the ENERGY STAR rating. Compare the star ratings between different models. Remember, more stars mean higher efficiency, helping you save on energy costs.
Energy Consumption and Wattage
Check the energy consumption figures on the Energy Rating Label for an estimate of annual power use.
This gives you a better picture of the long-term usage.
Features that Impact Efficiency
Features like inverter technology, eco modes, and smart sensors can optimise energy use.
Upfront Cost vs. Long-Term Savings
Though energy-efficient appliances may have a higher initial cost, long-term running costs on electricity bills often make them a smarter investment.
