Reducing your energy bill doesn’t have to involve giving up comfort. In fact, there are a few small changes you can make today to reduce your next energy bill – and you may not even notice them once they’re in place! Use these simple tips to take stock of what’s using excess energy in your home. Your future self (and the environment) will thank you for it.


1. Cut down on hot water

The biggest culprit energy guzzling in the home is hot water. Typically, more than half of it will be used in the bathroom, a third in the laundry and the remainder in the kitchen. With hot water usage, little things go a long way. Try using a shower timer to take shorter showers (reducing your shower by a couple of minutes can save you up to $100 on your energy bill each year), wash your laundry with cold water and rinse dishes in a sink full of water, rather than running water.


Using a more efficient hot water system is also important. If possible, install a heat pump powered by solar PV. Heat pumps run on electricity and can be up to four times more efficient than a conventional electric water heater. For a one- or two-person household, an instant gas heater is cheap to run.


2. Get smart about heating and cooling

Heating the home in winter and cooling it down in summer can quickly rack up the energy bills. In winter, some reverse-cycle air conditioners used for heating can be far more efficient than blow heaters, oil-filled column heaters and radiant bar heaters.



Make sure your home is well insulated by sealing cracks and gaps in windows and doors, closing curtains and blinds at night and using door snakes where needed.


In summer, choose fans over air conditioners and, if possible, cross ventilate by opening doors and windows to let natural breezes through your home.


Bonus tip: Bathroom heater lights can use a huge amount of energy. Check their wattage and use sparingly.


3. Switch off

Appliances left on stand-by use about 10% of your energy bill. While each appliance only uses a small amount of energy, it adds up. According to consumer group Choice, the biggest energy suckers in the home are:


Device Highest stand-by cost annually
Multi-function printer $118.20
Wireless VOIP router
Speaker docks $19.00
Washing machine
Microwave $4.72
Clothes dryer $1.72
Air con - large $1.08
Home theatre system $0.23
TVs - 100 to 115 cm $0.05
Blu-ray player $0.05


Switch your appliances off at the wall when they’re not being used or install a stand-by power controller that does it for you automatically.


4. Rethink your fridge

If you have an old or low star-rated fridge, it might be time for an upgrade. Replacing an old, inefficient fridge can save between $100 and $200 per year on your energy bills. Have a second fridge in the garage? Though it might be great for parties, you’ll save much more money with an esky when you need it.


If you are looking to upgrade, you may be eligible for a new fridge under the NSW Government appliance replacement offer.


5. Upgrade your TV

While a big, cheap television may be tempting, it could cost you in the long run. The type of technology, screen size and brightness all contribute to how much electricity your television will use. Generally, newer TVs use less electricity than older models.


When you buy your new television, look for the Energy Rating Label. By law, every TV sold in Australia must meet a minimum level of energy efficiency. If you’re considering an upgrade, find out whether you’re eligible for a new TV under the NSW Government appliance replacement offer.
