General Savings Advices

Remember to switch appliances off. This simple advice is still the most efficient.

Table 1. Advice and Savings.

Advice Potential savings Source
20° is enough. In the living-room, kitchen and bathroom, a temperature of 20° is enough. Keep temperatures in the other rooms lower. Electrical heating should be switched off whenever it is not in use, unless a minimum temperature is required to keep a room frost-safe. For each degree the temperature is lowered, 5-6% of energy consumption is saved. NRGi
Use thermostats with day and night settings. Lower the household temperature by 5-6° at night — and during the day when there is no-one home. If there is no automatic night-setting on your radiator, you can install a timer and a thermostat on the mains. Potential utility savings are app. 10%. NRGi
Use zone heating and cooling systems. Motorized dampers and thermostats can regulate heating in different zones according to preference, e.g. a warm kitchen in the morning and evening, but cooler during the rest of the day. Remember to keep the zones seperate, by keeping doors closed etc. Optimal zoning constructed according to room preferences can save up to 15-20% on the utility bill. NRGi
Use a thermos. Use a thermos to keep coffee warm, rather than leaving it on the coffee machine's hot plate. If you leave coffee on a hot plate for an hour, you use as much electricity as when you brew a liter of coffee. NRGi
Remove hard water deposits from your coffee maker. Both your coffee machine and electric kettle need regular maintenance, especially in areas with hard water. Too many mineral deposits increases electricity consumption, and increases the time it takes to brew coffee. NRGi
Turn down settings. Set your ventilation hood to its lowest possible setting when cooking. A ventilation hood uses app. 1.5 times as much electricity on its highest setting relative to its lowest setting. NRGi
Use a lid. Use a tight-fitting lid on your pot. Not using a lid requires 3 times as much electricity. NRGi
Use pots. Where possible, use a pot on a stove for cooking rather than the oven. Up to 70 % savings. NRGi
Defrost food before cooking. Most frozen goods must be defrosted before use. Frozen vegetables are the exception to this rule, and it is usually recommended to cook them while frozen. Electricity consumption will increase by up to 50 %, when pork chops are not defrosted before cooking. NRGi
Defrost in the fridge. Defrost as many foods in the fridge as possible, rather than using warm water or a microwave. It takes longer, but it is better for the quality of the product. This saves electricity. NRGi
Keep the vents in the fridge and freezer uncovered. Fridges and freezers release heat in order to cool, and the vents need to be free from obstruction to ensure proper cooling. Ensure as much air as possible around your appliances. If you are installing built-in appliances, ensure that you follow the guidelines. Without proper ventilation, the appliances have to work harder to keep things cool, which uses more electricity. NRGi
Shut the door. Only open the fridge doors for the briefest amount of time. Each time you open the fridge door, warm air enters the fridge, and it takes energy to cool it again. NRGi
Plus 5° C in the fridge and minus 18° C in the freezer. Measure the temperature in your fridge by placing a thermometer in a glass of water and placing it in the fridge for 24 hours. This will give you the most accurate result. Each degree below the optimal temperature increases electricity consumption by 5%, because the fridge has to work that much harder. NRGi
Low temperature - short cycle. Always use the shortest possible rinse cycle and the lowest possible recommended temperature when doing dishes. Washing at 50/55° uses 10-20 % less electricity than a program at 65°. NRGi
