The Energy star rating indicates how energy-efficient a product is, showing how much energy it consumes in comparison to similar products. More stars mean the appliance is more efficient, especially when compared to other models with similar size and features. The higher the star rating on the Energy Rating Label, the less energy the product will consume, which translates to greater savings on your energy bills.
The Energy Rating Label is a key component of the Australian and New Zealand Equipment Energy Efficiency (E3) Programme. It serves to help consumers identify energy-efficient appliances that not only reduce greenhouse gas emissions but also lower household utility bills. Products carrying this label adhere to strict energy efficiency standards set by the E3 Programme, ensuring they consume significantly less energy compared to non-certified models, all while maintaining or even enhancing their overall performance.

Energy-saving Hack: Use this calculator to compare energy-efficient appliances and estimate running costs for your home or business.
The Energy Rating Label helps you make informed choices about the appliances you buy. It provides two important pieces of information: the star rating and energy consumption:
- Energy Rating: It indicates the energy efficiency of the appliance. The more stars an appliance has, the more energy-efficient it is. Appliances are rated between 1 to 6 or 1 to 10 stars based on energy efficiency, allowing easy comparison with others of the same type and size. Appliances with higher star ratings typically use less energy, which leads to lower utility bills and a reduced environmental impact.
- Energy Consumption: This is shown in kilowatt-hours (kWh) and represents the amount of electricity the appliance uses annually. This helps you estimate running costs and compare appliances based on their energy usage.
By checking both the star rating and energy consumption, you can assess the overall energy efficiency of an appliance and choose the one that best meets your needs for both performance and cost savings.
Energy-saving Hack: When shopping for appliances, choose the one with the highest star rating within your budget. A higher rating can save you money in the long run.
The performance of an air conditioner is influenced by the climate in which it operates. Given Australia's diverse climate, with significant regional variations, the efficiency of air conditioners can vary greatly. To address this, most newly registered air conditioners in Australia feature the Zoned Energy Rating Label.
The Zoned Energy Rating Label is a special energy efficiency label applied to air conditioners and heating systems, reflecting their performance across different climate zones in the country. This Label provides more detailed information than its predecessor. It includes a seasonal efficiency rating for three climate zones across Australia and New Zealand: hot, average and cold. This helps consumers choose an air conditioner best suited to their location. The label uses white, grey and black ratings, depending on the climate zone. The performance of air conditioners is tested under simulated conditions to determine their energy rating for each zone.
At the top of the label, the output capacity for heating is provided at two outdoor temperatures and for cooling, it's listed at one outdoor temperature. The estimated annual energy use in kilowatt hours (kWh) is shown on the right side of the label, with separate figures for heating (red) and cooling (blue) in each climate zone. Additionally, noise levels are indicated at the bottom left, displaying the volume in decibels (dB(A)) for both the internal and external units of the air conditioner.
Energy Saving Hack: Choose an air conditioner that matches your specific climate zone for optimal energy efficiency. By selecting a model rated for your local conditions—whether hot, average, or cold—you can ensure it operates at its best, reducing energy consumption and lowering your bills.
Below is a breakdown of the various energy and water rating labels displayed on household appliances, highlighting their efficiency and sustainability features.
Energy-saving Hack: A simple change like upgrading your pool pump to a 10-star model can save hundreds of dollars in energy costs each year.
To estimate how much an electrical appliance will cost to run annually, you can use the Energy Rating Label. Simply multiply the appliance's yearly energy consumption (in kWh), mentioned on the label, by the rate you pay for electricity, which is available on your bill.
Annual running cost = Total energy consumption (kWh) × Electricity tariff (dollars per kWh)
For example, let’s compare the running costs of two 55-inch TVs:
- 7-Star Rated TV: A 7-star TV consumes 213 kWh per year. With a typical electricity rate of $0.28 per kWh, it would cost about $60 annually to run.
- 3-Star Rated TV: A 3-star TV uses 520 kWh per year. At the same rate, its annual running cost would be roughly $146.
By opting for the 7-star TV, you could save $86 each year. Over the course of 10 years (the typical lifespan of an appliance), this can result in savings of $860.
Energy-saving Hack: Compare running costs before buying—an energy efficient appliance may cost a little more upfront but saves you significantly over time.
When comparing Energy Star ratings on appliances, it’s important to look beyond just the number of stars. While more stars signify higher energy efficiency, it’s crucial to also examine the energy consumption (in kilowatt-hours, kWh) listed on the label. This indicates the annual electricity usage, helping you assess the long-term running costs.
Another key factor is comparing appliances of similar size and function. The star rating reflects energy efficiency relative to an appliance's size and features, so comparing different-sized appliances may not provide an accurate assessment. For example, a larger appliance, like a 10 kg washing machine, may consume more energy than a smaller 6 kg one, even if both have the same star rating.
To make an informed decision, always ensure the appliances you're comparing are of similar size and functions. And remember, choosing the right size for your needs is essential for maximizing energy savings.
Energy-saving Hack: Opt for appliances with smart features to adjust power usage and reduce costs. Also, buy an appliance size that fits your household to avoid unnecessary energy consumption.
Governments offer various rebates and incentives to encourage consumers to invest in energy-efficient appliances, as part of broader efforts to reduce energy consumption and greenhouse gas emissions. These incentives typically aim to make the upfront costs of energy-efficient products more affordable while ensuring long-term savings for households.
In many regions, rebates may cover part of the purchase. Additionally, some programs provide tax credits or direct subsidies for energy-efficient home improvements, including insulation and smart thermostats. These government initiatives help reduce the environmental impact of household energy use and foster a culture of sustainability while offering financial relief to consumers, especially through programs like the Victorian Energy Rebate.
Energy-saving Hack: Take advantage of rebates like the Victorian Energy Rebate to reduce your appliance purchase costs. It’s an easy way to boost your savings.
Choosing Energy Rating Label certified appliances is a smart investment for your home and the environment. They save energy and lower utility bills and also contribute to a sustainable future by reducing greenhouse gas emissions. Additionally, pairing these appliances with rebates and incentives, like those offered under the Victorian Energy Upgrades program, amplifies your savings. Make your next appliance purchase an informed one by prioritising the Energy Rating Label. Small changes today can lead to significant environmental and financial benefits tomorrow, with options like heat pump hot water systems further enhancing your energy savings.
