40 Practical Energy Saving Tips Every Australian Should Know

Reducing your energy bills doesn’t have to mean sacrificing comfort. By making a few small changes to your daily habits and home setup, you can lower your electricity use, help the environment, and keep more money in your pocket.

At UtilityDeals, we’ve gathered 40 proven energy-saving tips from households across Australia. These tips are simple, practical, and suitable for every type of home—whether you rent, own, or are just looking to cut down your power usage.

Free Energy Saving Tips That Work

The best way to start saving energy is by changing small everyday habits. These tips cost nothing to implement but can have a significant impact on your overall energy use.

Set timers on your heating and cooling systems
Schedule your air conditioner or heater to turn on just before you get home and switch off automatically when you leave. This prevents overuse and keeps your home comfortable without wasting energy.
Shorten your showers
Hot water is one of the biggest energy expenses in most households. Try limiting showers to a few minutes to reduce both water and energy consumption.
Cook in batches
When using the oven, prepare multiple meals at once. Cooking several dishes together maximises the heat already being used and saves energy over the week.
Close doors to unused rooms
Only heat or cool the rooms you actually use. Closing doors helps contain warm or cool air, reducing the workload on your air conditioning or heating system.
Layer up instead of turning up the heat
During winter, wear extra layers or use blankets before switching on the heater. It’s a simple and effective way to reduce energy use.
Adjust your thermostat slightly
Lowering your heater by just one degree in winter—or raising it by one degree in summer—can reduce energy use by up to 10% without affecting comfort.
Use natural light whenever possible
Open blinds and curtains during the day to make full use of sunlight instead of switching on lights.
Turn appliances off at the wall
Many devices continue to draw power even when not in use. Turning them off at the wall can save up to 10% on your energy bill.
Wash clothes in cold water
Most detergents work just as effectively in cold water. By skipping the hot cycle, you’ll use less energy and keep fabrics in better condition.
Air dry your clothes
Instead of using a dryer, hang clothes outside or on an indoor rack. The sun and air are free and highly effective.
Plan your appliance use around off-peak times
If you’re on a time-of-use electricity plan, run dishwashers and washing machines during off-peak hours to take advantage of cheaper rates.
Defrost naturally
Let frozen food thaw in the fridge or on the kitchen counter instead of using the microwave. It uses less energy and helps your fridge stay cool.
Use lids while cooking
Covering pots and pans reduces cooking time and keeps heat in, which means your stove or cooktop uses less energy.
Keep your fridge organised
A well-organised fridge allows cold air to circulate more efficiently and helps maintain an even temperature, reducing strain on the motor.
Use fans before air conditioning
Ceiling and portable fans consume much less energy than air conditioners and can make a noticeable difference to your comfort.
Match cookware size to your burners
Using the right pot size ensures heat isn’t wasted around the sides and helps cook food faster.
Block draughts with door snakes or towels
In winter, stop cold air from entering by placing door snakes or rolled-up towels at the base of doors.
Regularly clean filters
Air conditioners, dryers, and range hoods all work more efficiently when filters are clean.
Use your microwave or toaster oven for small meals
Smaller appliances use far less energy than a full-size oven.
Turn off lights when leaving a room
A basic habit, but one that adds up to meaningful savings over time.

Low-Cost Ways to Save Energy

These small upgrades require minimal investment and deliver noticeable reductions in your energy bills.

Install weather seals on doors and windows
Stop warm or cool air from escaping by adding simple rubber or foam seals.
Switch to LED lighting
LEDs use about 75% less energy than traditional bulbs and last significantly longer, reducing both electricity and replacement costs.
Replace old showerheads
A water-efficient showerhead can cut your hot water use by up to 50%, reducing both water and energy bills.
Use smart plugs and power boards
These allow you to automatically cut power to idle devices or set timers for electronics.
Upgrade your window coverings
Thermal curtains or blinds can help retain heat in winter and block sunlight in summer.
Use a clothes drying rack or line
Save money on energy by skipping the dryer, especially during warm months when clothes can air dry quickly.
Add insulation film to windows
Window insulation film is an affordable way to improve thermal performance and reduce heating or cooling loss.
Maintain your refrigerator seals
Test by closing a piece of paper in the door—if it slides out easily, the seal may need replacing.
Use rugs on hard floors
Rugs help insulate against cold air from beneath and make rooms feel warmer without extra heating.
Position your fridge and freezer away from heat sources
Keep them clear of direct sunlight or ovens so they don’t need to work as hard.

Bigger Energy-Saving Investments

If you’re ready to make more permanent improvements, these upgrades offer long-term efficiency and savings.

Upgrade to energy-efficient appliances
When it’s time to replace old appliances, choose models with higher energy star ratings. They consume less electricity and pay for themselves over time.
Install or improve home insulation
Good ceiling and wall insulation can cut heating and cooling needs by up to 40%.
Double-glaze your windows
Double glazing helps maintain indoor temperatures by reducing heat transfer through glass.
Invest in a solar energy system
Installing solar panels allows you to generate your own electricity and significantly reduce your energy bills.
Switch to a heat pump hot water system
Heat pumps use the warmth in the air to heat water, making them much more efficient than traditional electric systems.
Consider a home energy audit
A professional assessment can identify where your home is losing energy and suggest the most cost-effective improvements.
Use a smart thermostat
Smart thermostats automatically adjust heating and cooling based on your schedule and preferences, reducing unnecessary usage.
Upgrade outdated wiring
Old wiring can cause energy loss and safety risks. Modern wiring systems improve efficiency and performance.
Design for natural light and ventilation
Use skylights or larger windows to increase natural light and reduce the need for artificial lighting.
Review and switch energy plans regularly
Energy prices and offers change frequently. Comparing plans on UtilityDeals ensures you’re always getting the best value.
