As the weather heats up, the temptation to switch on the air conditioner grows stronger, but along with the cool air come higher electricity bills. Power bills remain one of the most unwelcome costs faced by Australian households, making energy efficiency increasingly important.
Changing the temperature of a room is one of the biggest contributors to higher electricity costs. It is estimated that around 40 per cent of household electricity use goes toward heating and cooling, though this varies widely between homes. While space heaters may appear cheap to buy, they consume large amounts of power, often leading to higher costs over time. Air conditioners are also energy-intensive, with some households paying hundreds of dollars extra each year due to air-conditioning use alone. Ceiling fans, although less powerful, are far more energy-efficient and can be used alongside air conditioners to reduce overall electricity consumption.
Hot water is another major source of energy use, accounting for about 23 per cent of household electricity consumption. Simple measures such as taking shorter showers and installing water-saving showerheads can significantly reduce power use. Bringing the showerhead closer to the body helps retain heat, while using cold water for washing clothes and filling kettles with cold water also contributes to energy savings.
Fridges are among the most power-hungry appliances because they operate continuously. Ensuring door seals are in good condition, limiting how often the fridge is opened, and avoiding purchasing a fridge larger than necessary can help reduce electricity use. Interestingly, a well-stocked fridge can use slightly less energy than an empty one. Spare fridges kept in garages should be switched off when not in regular use, especially if they are only needed for occasional events.
In the laundry, front-loading washing machines are generally more energy-efficient than top loaders, although they cost more upfront. Washing clothes in cold water is one of the most effective ways to save electricity, while line-drying clothes instead of using a dryer eliminates power use altogether.
Dishwashers may use less water than hand-washing, but they still consume electricity. Using eco modes and waiting until the dishwasher is fully loaded before switching it on can improve efficiency. Similarly, when it comes to ovens, reducing preheating time and cooking multiple items at once can help cut down power consumption.
Televisions also contribute to electricity use, with larger screens generally consuming more power. Modern LCD screens are more efficient than older plasma models, but the simplest way to save energy is to turn the TV off when it is not in use. Many devices continue to draw power in standby mode, so switching them off at the power point can make a noticeable difference.
Smaller appliances are often the more energy-efficient choice. Using slow cookers, air fryers or microwaves instead of ovens reduces energy use because they heat smaller spaces or operate for shorter periods. Boiling water in an electric kettle is also more efficient than using a stovetop, making it a smarter option for everyday use.
