52% of residential greenhouse emissions come from the use of electrical appliances.

Sustainable living is an attitude about your lifestyle. The Vale autonomous house in UK showed that simply by applying new attitudes towards appliance usage the household reduced power consumption by 25% without any technical innovations saving 570 kg of CO2 emissions in the kitchen and laundry practices alone.

Energy efficient practices to be adopted in the Newton House include:

1. Only energy efficient appliances have been purchased as indicated by the star-rating label. The more stars indicate less energy is used to achieve the same performance.

2. Appliances will be positioned in well-ventilated areas to maximize their efficiency.

3. Appliances are not used when an alternative is available. Use a cool ventilated pantry for storage of produce, passive design strategies instead of using heaters and cooling equipment, clothes line instead of dryer etc.

4. Appliances that draw power on a standby mode will all be turned off using a switch located at the front door. This switch will be separate from appliances such as the refrigerator.

Did you know that many appliances in your house will use more power per day in standby mode then they do being used. Consider your printer that draws 120 watts when in use, and 5 watts when in stand by. You use it for 5 minutes per day. 120w @ 5minutes = 10w. on standby it draws 2w/hour. 2w x 24hour = 48w. This is nearly 5 times the power used for the appliance when it is in use.

Consider how this will add up when you consider the computer, microwave, phone charger, DVD player, sterio. It is estimated that up to 8% of your household power consumption is used by standby power.

5. A master switch will turn off all non essential power when we leave our home. Similar to the system seen in motels.
