Level Up Your Energy Efficiency
Most of us are on top of the energy efficiency basics but are you an energy saving superhero? Think part scientist, part detective, a bit like Batman. Supercharge your sustainability powers with this simple guide.
- Better bulbs
Do you know the difference between incandescent, halogen, CFL and LED? Learn how lightbulbs work then check every lightbulb you can, including your classroom. LEDs use far less electricity than older types and last 5-10 times longer than the common incandescent bulb style.
- Check the wall
Many devices including televisions and washing machines still drain significant energy even in standby mode, so always remember to switch off at the wall when not in use.
According to the Department of the Environment and Energy, appliances that aren’t switched off at the wall can account for about 3 per cent of overall energy bills.
- Monitor screen time
Sleep mode is nice function when you step away from your computer but if you’re finishing up for the day always shut down properly. This may take an extra 2 seconds but it’ll save noticeable amounts of energy. As a bonus, you’re almost guaranteed to extend the life of your device by minimising wear and tear.
Research shows using your mobile phone for just one hour a day for one year produces carbon emissions comparable to two round-trip flights between London and Glasgow amounting to some 1.4 tons of carbon dioxide. Think about extending the battery life of smart phones and tablets. Activating power saving modes and using wifi in airplane mode will noticeably extend the time between charges.
- Shorter showers
Energy is consumed every time we use hot water and more often than not this comes from the grid or gas heating. Going cold turkey isn’t really an option in Winter months but consider halving the time you shower to save energy and water.
It’s important to practice good hygiene, but replacing daily baths with three-minute showers can save approximately 849kg CO2 per year.
- Look to the stars
Have you ever noticed the star sticker on your fridge?
Most electrical and electronic products in Australia will have an energy star rating, the higher the better! The Energy Rating Label is mandatory on new TVs, computer screens, clothes dryers, dishwashers, washing machines, and air-conditioners. Larger items such as fridges may still have the factory stickers attached but other items may require a bit of online research.
Obviously it’s not cheap to upgrade low rate, inefficient appliances but it’s important to take note to minimise usage and get the best replacement when the time comes.
Remember all of these apply at home and school! You can always track your school’s energy efficiency through your school’s portal page.
