With Sydney electricity prices among the highest in the world, choosing energy-efficient appliances has never been more important. This guide explains how to choose appliances that keep your energy bills low — and how second hand appliances can still be energy-efficient choices.
Understanding Energy Star Ratings in Australia
Australia uses the Energy Rating Label system: more stars = lower running cost. When comparing appliances, always look at:
- The number of stars (1–6, with more being better)
- The annual kWh figure – this is the actual energy the appliance uses per year
At current Australian electricity prices (~30 cents/kWh), a 1-star vs 4-star fridge could mean a difference of $80–$120 per year on your bill.
Most Energy-Hungry Household Appliances
- Air conditioner – Biggest energy user in most Australian homes in summer. A 5-star split system uses 50% less energy than a 2-star unit.
- Refrigerator – Runs 24/7, so efficiency matters enormously over its lifespan.
- Clothes dryer – Heat pump dryers use 40–60% less energy than vented or condenser dryers.
- Washing machine – Front loaders use less energy and water than top loaders.
- Dishwasher – Modern dishwashers use less water and energy than hand washing.
How to Reduce Appliance Running Costs
- Run your dishwasher and washing machine on off-peak electricity (typically overnight)
- Set your fridge temperature to 3–4°C (not colder — every degree colder adds ~5% to energy use)
- Use your air conditioner's economy/auto mode rather than blast cooling
- Clean your fridge's door seals and condenser coils to maintain efficiency
- Wash clothes in cold water — modern detergents work just as well
Are Second Hand Appliances Energy Efficient?
It depends on the age. Appliances made in the last 5–10 years are still reasonably efficient. Very old appliances (15+ years) pre-date modern efficiency standards and can cost significantly more to run. At Oceania, we focus on stock from the last 5–10 years, ensuring our second hand appliances deliver a good balance of price and running cost.
