Want to know how to save energy at home and actually see a difference on your power bill? With electricity costs rising across Queensland, more locals are looking for easy, practical ways to cut energy use without changing their lifestyle. Whether you want to save money, reduce your carbon footprint, or get more out of your appliances, a few smart changes can go a long way.
Why Saving Energy Matters
It’s not just about saving money, though that’s a big win. Using less energy also:
- Lowers greenhouse gas emissions
- Takes pressure off the grid during peak times
- Helps your appliances run better and last longer
- Keeps your home more comfortable year-round
According to Energy.gov.au, heating and cooling make up about 40% of the average household’s energy use. So if you’re blasting the aircon or heater every day, there’s real room to save.
Top Energy-Saving Tips for Aussie Homes
These practical tips are perfect for homes in Queensland, where summer heat is no joke and aircon is a must-have:
1. Switch to LED Lighting
Still using old-school bulbs? Swapping them for LEDs can cut your lighting costs by up to 75%. They also last heaps longer and don’t pump out heat like halogens.
2. Choose Energy-Efficient Appliances
When upgrading your fridge, aircon, or dryer, check the Energy Rating Label. More stars mean better efficiency. A five-star aircon might cost more upfront, but it can save hundreds over time.
3. Use Timers and Smart Plugs
These are a simple way to make sure things like pool pumps, heated towel rails, and outdoor lights only run when you need them. Less waste, less stress.
4. Seal and Insulate Your Home
If hot air is sneaking in or cool air is leaking out, your aircon’s working overtime. Sealing gaps and adding insulation in the ceiling can make a noticeable difference.
5. Optimise Your Aircon Use
Set it to 24°C in summer and 18°C in winter. Even one degree difference can bump up energy use by 10%. Also, clean your filters regularly and close off unused rooms to keep things running efficiently.
6. Turn Off Standby Devices
TVs, game consoles, microwaves and even phone chargers use power in standby mode. Turn them off at the wall or use a smart power board to make life easier.
7. Install Solar Panels
If your roof gets good sun, solar can be a game-changer. Pair it with energy-efficient appliances and you’ll really see the savings stack up.
How to Calculate Energy Efficiency (Without a Physics Degree)
Once you know how to save energy, the next step is figuring out whether it’s actually working. That’s where understanding how to calculate energy efficiency comes in handy.
Let’s keep this simple: Energy efficiency is about getting the most out of the energy you’re using. The less energy wasted, the more efficient your appliance is.
A Handy Formula:
- Energy Efficiency = (Useful Output ÷ Total Input) × 100
- Say your heater uses 1000 watts, but only 700 go toward actual heating: (700 ÷ 1000) × 100 = 70% efficient
You don’t need to crunch numbers for every appliance, but it helps to know how to spot energy guzzlers.
Look for the Energy Rating Label
All new appliances in Australia come with this label. It shows:
- Star rating (more stars = better efficiency)
- Estimated yearly energy use in kilowatt hours (kWh)
Want to Know Running Costs?
Here’s a simple formula:
(Wattage × Hours Used Daily) ÷ 1000 = Daily kWhDaily kWh × Electricity Rate = Daily Cost
Example:
- A 2000W heater used 2 hours a day = 4kWh
- At $0.30 per kWh, that’s $1.20 per day

They help you compare appliances, check costs, and figure out where you might be losing energy.
Big Energy Wasters in the Home
Here are some of the usual suspects when it comes to high energy use:
- Old fridges: They run 24/7 and older models are often energy hogs
- Halogen or incandescent lighting: Burns through energy and gives off heat
- Inefficient aircon units: Especially older or poorly maintained systems
- Pool pumps: Use a heap of power if not set on a timer
- Standby power: TVs, consoles, and chargers sip energy all day
