How to Reduce Your Appliance Energy Bills: A Practical Guide
Major home appliances — fridge, washing machine, dishwasher, dryer and oven — account for a substantial portion of household energy bills. With Sydney electricity prices now averaging 30–35c/kWh, reducing appliance energy use has real financial impact. This guide gives you practical, evidence-based steps to cut your appliance energy costs without sacrificing convenience.
Refrigerator: Your Biggest Continuous Energy User
Your fridge runs 24 hours a day, 365 days a year, making it the single biggest appliance energy user in most households. Here's how to minimise its consumption:
- Set temperatures correctly: Fridge at 3–4°C, freezer at -18°C. Every degree colder costs more energy with no food safety benefit
- Keep coils clean: Dusty condenser coils force the compressor to work harder. Clean them annually with a vacuum
- Check door seals: A leaking door seal lets cold air escape continuously. Test with a piece of paper — it should grip firmly when the door is closed
- Allow air circulation: Leave a gap behind and above the fridge for heat dissipation
- Don't put it near the oven or in direct sunlight: Ambient heat forces the compressor to work harder
- Fill it reasonably: An empty fridge is less efficient than a stocked one because food acts as thermal mass
Washing Machine: Temperature Is the Key Variable
Up to 90% of a washing machine's energy goes into heating water. Switching from 60°C to 30°C washes reduces washing energy by approximately 60%. Modern detergents perform effectively at 30°C for lightly to moderately soiled clothing. Reserve hot washes for heavily soiled items, bedding and towels.
- Wash full loads, not partial loads
- Use cold or warm rather than hot for everyday loads
- Choose eco programs — they use less water and energy by extending wash time
- Spin at full speed to remove more moisture and reduce drying time
Dryer: Use Strategically, Not Constantly
Clothes dryers are energy-intensive. A vented or condenser dryer uses 2–4kWh per cycle, costing 60c–$1.40 per load. A heat pump dryer uses about 1–1.5kWh per cycle, cutting this cost in half. Strategies to reduce dryer energy:
- Air-dry when weather and time allow
- Use high-speed spin before transferring to dryer to reduce drying time
- Clean the lint filter before every load
- Upgrade to a heat pump dryer if you use the dryer frequently
Dishwasher: Small Habits, Real Savings
- Run full loads only — a half-full dishwasher uses the same energy as a full one
- Choose eco programs over intensive programs for lightly soiled loads
- Use the AirDry or door-opening drying function (available on Electrolux, Bosch and others) rather than heated drying
- Skip the pre-rinse — modern dishwashers are designed to handle food residue, and pre-rinsing wastes water and time without improving results
When to Upgrade for Energy Savings
An old, inefficient fridge or dryer may cost more in annual running costs than a new efficient model's purchase price divided over its lifespan. As a rule: if an appliance is 10+ years old, calculate its Energy Star rating vs a modern equivalent. For fridges and dryers in particular, the efficiency improvement from a decade of technology advancement is often dramatic.
