Energy Consumption At Home

Electricity Use By Home Appliances

Wondering why your electric bill is so high? Perhaps your appliances aren’t energy efficient. If that’s the case, this guide will help you understand how much electricity your appliances use every year, and how they impact your wallet.

Washing Machines

On average, a family of five uses a washing machine six hours a week. Doing laundry costs more than $150 a year. If your family is shopping for a new washer or dryer, high-efficiency appliances will run more efficiently and use less electricity. Of the two appliances, dryers use the most electricity. Therefore, consider air drying clothes to reduce your household’s energy use. To cut costs even further, wash clothes in cold water. This saves the electricity used to warm water.


The average Australian watches 4 hours of TV a day. In one year, that’s over 2 months of viewing. If you own a 40-inch HDTV, expect to pay $52 annually for 341kWh. If you’re planning to upgrade your TV soon, switch to an LCD TV, which runs at 150-Watts and costs under $37 a year.


As an appliance that runs all day, all year round, a refrigerator uses 657kWH annually, costing you around $100 over 12 months. Compared to other large appliances, this cost is surprising. Set your fridge to an optimal temp, between 0 and 4oC. This ensures your food stays cold without your unit having to work harder than usual. Maximising its efficiency will lower your electricity use and increase your energy savings.

Central Air Conditioning

While an air conditioner varies depending on where you live and your home’s size, a 3-ton central AC unit is common in many Australian homes. The average 3-ton AC operates at 3.5kWh per hour. If you run your air conditioning unit for 9 hours a day during summer, the electricity required to cool your residence will cost around $592 annually.

Keep your home at a comfortable temp, while keeping an eye on the electric bill. That’s possible using the program features of a thermostat. Make sure your air conditioner is set to turn off when you don’t need it.

Changes to Make to Bring Down Energy Costs

Besides being aware of how much electricity your appliances utilise, making changes to your daily routine can save you money on energy bills.

  1. Keep your fridge full and closed. Food acts as insulation. It lessens the span a fridge has to cycle to stay cool. Once every three months, clean the refrigerator coils
  2. Install ceiling fans to keep air circulating in your home and ease your air conditioner’s work.
  3. Set up an attic fan that’ll remove hot air from your home.
  4. Shield your house from the sun. Close blinds and curtains or install tinted window films for more savings.
  5. Eliminate phantom loads, including televisions, stereos, computers, DVD players and most kitchen appliances.
  6. Schedule yearly HVAC maintenance to increase your system’s efficiency. Change your filters once every month.
  7. Switch to LED light bulbs and dimmer switches.
  8. Upgrade to Energy-Star appliances, which use less energy.
