Listen up. Here are some wise words you don’t hear often enough in public discourse, but it’s the sort of wisdom we can all embrace: energy efficiency isn’t about cold showers and warm beer. It’s not about unplugging your utilities either. There are really simple decisions you can make that will save you heaps of money without the need to change your lifestyle.
It’s time to rethink energy efficiency
In the last 100 years in the developed world, we’ve gotten used to the idea that we have unlimited energy available at our fingertips. While that’s not going to change any time soon, a lot of effort and resources go into making that possible.
Energy isn’t frivolous and it isn’t free, so the challenge is this: how do we make energy affordable and available, while protecting our planet?
While technology and innovation will play the biggest part in ensuring our energy sustainability into the future, as consumers we have a role to play too.
For everyday Australians, energy efficiency is more about being mindful than making sacrifices. If you make some smart decisions around the home to improve the environment or effectiveness of the products you use, your comfort levels will also increase.
So how do you put that into practice? Here’s my top five simple, yet really effective tips for cutting your electricity bill.

The perfect hot shower every time
If you rely on electricity to heat up your water, you might be surprised to know that this typically makes up one third of an average Aussie family’s electricity bill.
Most of us start up a shower by cranking up the hot water tap. When it gets too hot (typically before having even jumped in), we turn on the cold tap to cool it down til we reach the ideal temperature.
There’s a much smarter way to perfecting your shower. By simply adjusting the temperature at your hot water system to a level that hits the sweet spot, you can save daily – multiple times if you’re a family – on massive amounts of energy that’s otherwise wasted by overheating your water.
- Get back to doing what Nana used to do
Fixing those wintry draughts can go a long way to keeping your home comfortable, with added benefits for your hip pocket.
They may not be sexy, but those draught or door snakes your Nana was fond of will do wonders to prevent cold air from coming in and to stop hot air escaping at the base of your doors and windows (and vice versa in the summer time).
Rather than competing with draughts, you can fix them so you have a more comfortable and stable room temperature and are less reliant on maxing out your heating or cooling.
If draught snakes are just not your thing, there are plenty of other more discreet options for draught-proofing your home such as tape or gap filler (caulk) to seal gaps and cracks, dedicated door seals, and closing off vents.
Using a ceiling (or pedestal) fan in combination with the air conditioner is a clever way to save.
- Make the fan your number one
When it comes to air conditioners, in summer every degree cooler than 24 degrees uses about ten per cent more energy. Likewise, every degree warmer on the thermostat of your split system heater can increase the heating component of your energy bill by ten per cent.
Yet, a ceiling or pedestal fan can use one tenth the energy of an air conditioner for the same room. So before you get hasty with the temperature on the air conditioner thermostat, consider first turning on a fan to work in conjunction with the air conditioner to provide a cooling breeze. It can make a huge difference and is less energy-intensive, allowing you to set your heating or cooling to a more moderate temperature.
- The more stars, the more savings
Data shows that more efficient appliances and smarter house design have a big effect on energy efficiency. The rule of thumb is: if you replace an old, inefficient long-life whitegood with a new one, no matter what you pay, it will likely be more energy efficient as the bar for baseline performance is constantly being raised.
That said, if you can afford to pay a little more for a major appliance with a better energy star rating, it will have paid for itself in a year or two and you’ll be rewarded with 10-plus years’ worth of energy savings.
So if you’re thinking it’s time to upgrade your washing machine, there’s a very valid argument for making the purchase and forking out a little extra upfront. You’ll likely save on water too.
- Take advantage of new tools
There’s a bunch of new and helpful tools out there that can help you make smart decisions and take control over your energy consumption.
These tools allow you to set your appliances, such as your dishwasher or washing machine, to operate during off peak periods when there’s less electricity demand and lower rates. They also allow you to remotely switch on and off appliances via a phone, tablet or computer.
We recently developed a home energy app called Eddy that’s being trialled in Western Australia and Queensland. When it becomes available next year through Australian company HabiDapt, households will be able to take control of their energy consumption anytime and anywhere.
Meanwhile, our AccuRate software tool is the industry benchmark for assessing the energy efficiency of homes. It’s used by designers and architects to model, measure and compare the energy efficiency of house designs. This is helping Australians move into a new era of comfort and energy efficiency.
To Infinity and beyond: here I am generating kinetic energy at the Infinity Swing in Sydney.
The CSIRO Infinity Swing
This isn’t really an energy saving tip, but it is one way of turning good clean fun into good clean energy.
You may have heard about our CSIRO Infinity Swing which just finished up in Sydney. Thousands joined us at Circular Quay to have a go on our 8-seater swing, where they converted their momentum into sustainable energy to power the stunning light and sound installation.
We’re not done yet, the Infinity Swing is heading down to Federation Square in Melbourne from Monday 16th to Saturday 21st November 2015, and it’s free for all.
We will have representatives on hand to discuss our ongoing energy research and discuss other useful tips for saving energy around the home. For more information, visit: infinity.csiro.au
