Check the usage section of your electricity bill for kilowatt-hours (kWh), then compare it with the same period last year and with your retailer’s daily usage data, if available. A smart meter or in-home monitor can show when your household uses the most electricity, such as during heating, cooling or hot-water cycles. Remember that your bill also depends on tariffs, supply charges and any discounts, not just how much electricity you use. For current tariff information and energy-saving guidance, check your retailer and the Australian Government’s energy.gov.au website.
