How to Make an Energy Efficient Smart Home

Choosing the right appliances will make a big difference to the amount of energy you consume in your home. Learn how to effectively minimise running costs and reduce power at the same time.

The CSIRO (Commonwealth Scientific and Industrial Research Organisation) is Australia’s national science agency, helping to advance Australia with a range of inventions and innovations that make positive impacts on the lives of people. Below is their simple guide that will get you more energy-savvy in the home:

1. Star Ratings

When you are buying household appliances, be sure to look out for water and energy star rating labels. These star rating labels will help you save energy, because the more stars on the label, the less energy that appliance uses. In the long run, this saves you lots of money on your electricity bills.

2. Running Costs

First, find the wattage (measure of electrical power) on your appliance. It is either clearly labelled or printed onto the appliance or on the packaging. Turn your wattage into kilowatts by dividing it by 1000.  For example, if your heater is 3,000 watts, then the kW should be 3 kW.

Second, multiple your kW (above) by the time the appliance is used, to get the kilowatt hours (kWh) consumed for that period. Then, multiply your kWh by an average cost of $0.22 (retailer’s tariffs will differ, so use this is as a guide) to get the cost. For example, your 3 kW heater used for 2 hours will consume 3×2 = 6kWh and costs 6x$0.22= $1.32 to run, or $0.66 an hour.

You can use the Green Savings Online Calculator to help calculate your costs.

3. Minimise Stand-By Power

If appliances are not turned off at the wall, they will be likely still consuming power. Consider getting a stand-by power controller and connect multiple appliances to the one unit. For example, when you turn off your main device such as the TV, the power is cut to the other appliances too. Check with your local council to see if you are eligible for a free stand-by power controller.
