Energy Star Ratings Explained: How to Read the Energy Label on Appliances
Every major appliance sold in Australia must display an energy rating label. But what do those stars and numbers actually mean? This guide explains how to read the label and use it to make smarter buying decisions.
What Is the Australian Energy Rating Label?
The Energy Rating Label is a government-mandated label displayed on fridges, washing machines, dryers, air conditioners and dishwashers. It shows how energy-efficient a product is compared to similar products on the market. The label was introduced to help consumers make informed choices and reduce energy consumption nationally.
The Star Rating
The coloured bar at the top of the label shows the star rating, ranging from 1 to 10 stars (some labels go up to 10 with an extended scale). More stars = more efficient.
- 1–2 stars: Below average efficiency
- 3–4 stars: Average to above average
- 5–6 stars: Good efficiency
- 7+ stars: Excellent efficiency
The position of the arrow on the coloured scale also tells you how the product compares to others in its category — the further right it sits, the better it is relative to the market.
The Annual Energy Consumption Figure
Below the star rating is a large number showing estimated annual energy consumption in kilowatt-hours (kWh). This is calculated using a standard usage pattern for that appliance type.
To estimate your annual running cost, multiply the kWh figure by your electricity rate. If your rate is 30c/kWh and the fridge uses 450kWh per year: 450 × $0.30 = $135 per year to run.
Comparing Products Using the Label
The energy label is most useful when comparing two similar-sized products. A fridge with 5 stars and 450kWh/year is more efficient than one with 3 stars and 600kWh/year. Over 10 years, the more efficient model saves 1,500kWh — roughly $450 at current rates.
Zoned Energy Rating Label (ZERL)
Some appliances (particularly air conditioners) now display a Zoned Energy Rating Label (ZERL) with separate ratings for different climate zones. Australia's climate varies significantly, and an air conditioner's efficiency can differ between hot, cold and mixed climates.
Water Efficiency Labels
Washing machines and dishwashers also carry a separate Water Efficiency Labelling and Standards (WELS) rating. This shows water consumption in litres per use and a star rating for water efficiency. More stars means less water used per cycle.
Tips for Using Energy Ratings When Buying
- Compare models of the same size and type — a large fridge will always use more energy than a small one regardless of star rating
- Calculate the running cost over 10 years, not just the purchase price
- A more efficient model often pays for itself in energy savings
- Look for both energy AND water ratings on washing machines
