I will assume this question is referring to ways of saving energy in the home.
According to a survey conducted by the Energy Agency in North Rhine-Westphalia, a five-person household consumes on average between 4,600 and 5,500 kWh per year, with the biggest power guzzlers being lighting and consumer electronics, including computers. A single-person household consumes on average between 1,500 and 1,900 kWh per year, and in this case it is refrigerators and freezers that use the most power.
So here are some energy-saving tips: Make use of daylight whenever possible; use energy-saving light bulbs; take note of the energy label when buying new household appliances and consumer electronics; try to do without a tumble dryer; and do not leave your computer, printer, or monitor running or on stand-by. Other electrical appliances such as coffee machines, televisions, video recorders and power adaptors also consume power in stand-by mode. The main principle here is: If you are not using it, turn it off.
