No-Cost Energy Saving Tips
These solutions won’t cost you a cent, and are simple things you can do around your home to save energy and money.
- Run only a full dishwasher and use your dishwasher’s automatic energy-savings cool-dry cycle. If your dishwasher doesn’t have this feature, turn it off after the final rinse and let the dishes air dry. Doing this can reduce dishwasher energy usage by 40 percent.
- Wash your laundry in cold water when possible. In top-load models, about 90 percent of the cost per load is to heat the water.
- Do the laundry after 7:00 p.m. to reduce unwanted heat and humidity in your home or dry clothes outside on a line to save energy and avoid the heat a dryer generates.
- Wash only full loads in your washing machine and adjust the water level as needed.
Heating and cooling:
- In the winter, set your thermostat to 20 °C — and lower when it makes sense. Your heating system will operate less and use less energy. Turn your thermostat down another 2 degrees at night or when leaving your home for an hour or more to save even more on energy costs.
- Let natural sunlight into your home by opening window coverings on south-facing windows to warm your home. Keep window coverings closed in rooms that receive no direct sunlight to insulate from cold window drafts. At night, close window coverings to retain heat.
- In the summer, turn your heat pump off and use fans to keep cool. If you do use air-conditioning, increase the setting on your thermostat as high as you can and still maintain comfort.
- Keep drapes and blinds closed during the day to block out heat from the sun.
- Hot water should be no more than 60°C at the cylinder (to prevent the growth of legionella bacteria) and no more than 55°C at the tap so you don’t get burnt (children are particularly vulnerable). Extremely hot water can lead to higher energy costs and even scalding accidents.
- Keep showers short and use low-flow shower heads. A shower takes less hot water than a bath, but only if it is short in duration.
- Check the condition of your hot tub cover and check for escaping steam. Insulation blankets help keep the tub toasty for your use.
- Stagger pans on upper and lower oven racks to improve air flow because food cooks more quickly and efficiently in ovens when air can circulate freely. Don’t lay foils on racks.
- Use glass or ceramic pans in ovens. With those types of pans, you can turn down the temperature about 10 Celsius degrees and foods will cook just as quickly.
- Watch the clock or use a timer instead of opening the oven door frequently to check the food. Each time you open the door, the oven temperature drops by 10 Celsius degrees.
Other things you can do:
- Turn on your old, inefficient fridge in the garage only for those few occasions when you need extra refreshments.
- Keep your refrigerator closed while deciding what to eat. Each time you open the fridge door, the compressor has to run for eight to ten minutes to keep the cold inside.
- Make sure you and all your family members turn off the lights when leaving a room.
