Are you the sort of person who leaves the lights on when you’re out all day or more the type to switch the toaster off at the wall when you’re not using it? While both can be the cause of much tension in a share house, they’re also responsible for the number at the bottom of your subsequent bill.
But do some appliances consume more energy than others, or are certain habits more to blame?
If you have a tendency to leave the air conditioner on overnight, prepare to sweat. According to research by the Federal Government, our efforts to keep ourselves thermoregulated are the biggest contributing factor to a staggering energy bill.
‘Heating and cooling’ account for 30% of our total energy bill, followed by 20% for hot water and 12% for refrigerators and freezers. Lighting, cooking products and white goods appliances, and IT and home entertainment come in about equal at 8%.
While there are small discrepancies between states (because Queensland is hotter than Tasmania, obviously), the trends are mostly the same with heating/cooling and hot water systems always contributing the largest bite to the energy bullet (so much so that heating/cooling contributes over 40% in our cooler states—we’re looking at you Tasmania and Victoria).

Now that you’ve got a handle on your usage habits, what about the appliances themselves?
Have you ever seen those labels covered in stars on your white goods? That’s the ‘Energy Rating Label’ and it turns out, you should pay it more attention. The label indicates the energy efficiency of the product and tells you how many kWh it consumes (more on deciphering that term here). In short, the more stars, the more energy-efficient the product is compared to other models in its category.
Appliances with a higher star rating may cost more at the outset but they’ll probably save you more in the long run. For example, using an estimated energy price of $0.3 (30c) per kWh, a television with a seven-star label of 100kWh would cost you approximately $30 per year to run. A television with a three-star label of 400kWh, on the other hand, would cost $120 per annum. That’s a difference of $90 every year. Assuming your television lasts ten years, you could buy a pretty sweet new set with $900.
While this is just an example, the figures can be more substantial when dealing with larger, more energy-draining appliances like the fridge and washing machine. You can use your current price of energy (the rate found on your bill) to calculate exactly how much an appliance will cost you to run.

Aside from choosing energy-efficient products and opting for socks over central heating, there are a number of things we can do to reduce the price we pay for power.
Our energy bills are predominantly affected by two things: the price of energy and our consumption habits. To fix the former, read here. To fix the latter, there are a lot of small habits that can make a big difference.
