Here are 30 simple things you can do (from the ABC), plus a few suggestions from me and other commenters on the ABC website:
1. Turn off the beer fridge during the week or between parties.
2. Dry clothes on an airing rack or on the clothes line, rather than using a tumble dryer.
3. Clean the lint filter in washing machines, dryers, and heating and cooling equipment.
4. Use a rake instead of an electric leaf blower, or a broom instead of a vacuum on sealed floors.
5. Keep your fridge operating efficiently by keeping the door seals clean (replace them if they've deteriorated) and defrost the freezer if necessary.
6. Buy efficient whitegoods when the time comes to replace them. The Energy Rating website has a useful search tool that estimates running costs. For example, one 4-star family fridge costs $72 per year to run, paying 25 cents per kilowatt-hour for electricity, while a similar sized 1.5-star machine costs $135 per year to run.
7. If you have them, limit the use of heated towel rails to a couple of hours per day, instead of the full 24.
8. Put lids on saucepans to reduce the heat that escapes.
9. Cut your vegies into smaller pieces so that they cook faster.
10. Boil the kettle with only as much water as you need. Heating water takes a lot of energy.
11. Where possible, use a microwave instead of a conventional oven.
12. Turn off the television and other entertainment devices manually, instead of leaving them on standby. Master/slave powerboards can make this easier (despite dodgy-sounding name): when you turn off the 'master' (usually the TV), the 'slave' devices are automatically turned off.
13. Battery chargers can use standby power even when not plugged into the device they charge. Turn them off at the wall. This includes mobile phone, power tool and battery rechargers.
14. So you've swapped your old incandescent bulbs for more efficient lights? Now, it's time to replace energy-hungry halogen downlights. Mains voltage (GU10 base fitting) 50 Watt halogens can be replaced with 11-watt compact fluorescent 'micro' downlights. Low-voltage (MR16 base) 50-watt halogens can be replaced with 20 Watt infrared coated (IRC) halogens or three Watt LED downlights. Note that 'low voltage' does not mean 'low energy'.
15. Match your lighting levels to the needs of the activity you're doing. For example, you don't need every light on while watching TV.
16. Combined light, heat lamp and fan fittings for bathrooms are compact and useful, but each heat lamp typically uses a massive 275 watts. Don't flick on the heat switch when light is all you need.
17. Dress for the season. Winter is the time for woollies, rather than wearing summer clothes and setting the heater thermostat to tropical.
18. Similarly, suit your bedding to the season and use extra blankets (including underlay) rather than electric blankets or running a heater overnight.
19. Don't scoff at a nana-rug to cover your knees while you're watching telly. Thousands of nanas can't be wrong.
20. Cover windows with thick, well-fitting curtains.
21. Put weatherstripping on external doors or use a door snake.
22. Target heating to the rooms or zones in use, not the entire house.
23. Set your thermostat to a reasonable temperature of 18 to 20ºC in winter. Each degree hotter can increase your energy bill by about 10 per cent.
24. The shorter your shower, the less energy you spend heating up water. 25. Install a water-saving showerhead; it's an easy DIY job. Many water retailers have free showerhead replacement programs.
26. Consider insulated coverings for hot water systems and pipes.
27. When the weather heats up again, remember it is easier to prevent your house becoming hot than it is to cool an already hot house. Make sure your home has adequate exterior shade, such as awnings, blinds, sails, shade cloth, shade trees or verandas.
28. Install flyscreens to make it easier to ventilate your home.
29. For active cooling, fans use the least energy, followed by evaporative coolers (which suit dry climates). Air conditioners are the most expensive to run.
30. Fans work by moving air over your skin. If you're not in the room, the fan is doing nothing. Switch it off.
StuffFinally, remember that every product you see in the shops has needed energy, water and material resources to be produced and has a carbon cost. We can cut our eco-footprints, save money and avoid some of the carbon tax by simply buying and wasting less stuff."
So lots of common sense stuff there, thanks Auntie.
A few other thoughts:
1. Hot water is a massive part of energy bills, other ways to save money include:
- Turn down the temperature on your hot water cylinder, 65 dC works for us
- Better yet, get rid of your hot water cyclinder, having a big tank keeping hundreds of litres of water hot 24/7 is crazily inefficient. Look into some sort of instantaneous heating system.
- Install solar hot water
3. Install solar panels. If you live in QLD and have been thinking about going solar, you should get in before July 9th when the feed-in tarrif changes. You don't have to have the panels installed by then of course, contact a solar installer and they'll tell you what you need to do.
