How to Reduce Your Electricity Bill with Energy-Efficient Appliances
Household appliances account for a significant portion of an Australian home's electricity consumption. With electricity prices in NSW among the highest in the developed world, the appliances you choose and how you use them have a real, measurable impact on your quarterly bills. This guide shows you how to reduce electricity costs through smart appliance choices.
Understanding the Energy Star Rating
All major appliances sold in Australia carry an Energy Star Rating, a government-mandated label that shows the appliance's annual energy consumption and its rating relative to comparable models. More stars = lower running costs. The label shows both the star rating and the actual annual kWh consumption, which is the most useful figure for calculating real running costs.
At current NSW electricity rates (~$0.35/kWh), the annual electricity cost of an appliance is: Annual kWh × $0.35
For a fridge rated at 400 kWh/year, that's $140/year in electricity, or $1,400 over 10 years. The same fridge rated at 250 kWh/year costs $87.50/year — a saving of $52.50/year, or $525 over 10 years. For an appliance purchase that might cost $200–$300 more for the energy-efficient model, the payback period is typically 4–6 years.
Fridge and Freezer
Your fridge and freezer are always on, 24/7, 365 days a year — making them the most significant long-term electricity consumers in most homes. Upgrading from a 10-year-old 2-star fridge to a modern 4-star model can reduce fridge electricity consumption by 40–50%.
Tips for reducing fridge energy consumption:
- Keep the door seal in good condition — a deteriorating seal allows cold air to escape continuously
- Allow hot or warm food to cool before refrigerating — hot food forces the compressor to work harder
- Keep the fridge at least two-thirds full — thermal mass helps maintain temperature
- Ensure adequate ventilation around the fridge (25–50mm clearance on all sides)
- Defrost a manual-defrost freezer regularly — ice build-up reduces efficiency
- Keep the fridge away from heat sources (oven, direct sunlight, dishwasher exhaust)
Washing Machine
Washing machines consume energy in two ways: electricity to run the motor and pump, and energy to heat the water. Cold water washing (now possible with most modern detergents) dramatically reduces a washing machine's energy consumption. If your machine is heating water on most cycles, switching to cold water saves more energy than buying a more efficient machine.
- Wash in cold water whenever possible
- Wash full loads rather than half loads (less efficient per kg of laundry)
- Use a shorter cycle for lightly soiled items
- When replacing, look for 5-star energy and water rated models
Dishwasher
Modern dishwashers are more water and energy efficient than hand washing, but only when run full. Running a half-full dishwasher every day wastes both water and energy. Run the dishwasher on the eco cycle (lower temperature, longer cycle, lower energy) rather than the normal or intensive cycle unless dishes are heavily soiled.
Oven and Cooktop
Induction cooktops are approximately twice as energy efficient as gas and significantly more efficient than radiant electric. Ovens benefit from opening the door as rarely as possible — each opening drops the oven temperature significantly, requiring more energy to recover.
The Appliance Upgrade Calculation
When deciding whether to replace an older appliance with a newer, more efficient model, compare: (annual saving in electricity) vs (cost of new appliance minus trade-in or second-hand value of old appliance). If the payback period is under 7–8 years for a fridge or washing machine, upgrading makes economic sense.
