Households' electricity consumption
Results
30-40 % of the variation in household electricity consumption can be explained by objective data on residents and their homes. The main reasons for the electricity consumption is the number of people in the household, total household income and size of the household. The residents' age, especially if there are teenagers in the family, also contributes to a certain extent. The number of people is the objective factor that has the greatest influence on household electricity consumption. But electricity consumption per. person decreases with household size, and the current trend of increasing number of households with one-two persons and are therefore a factor which helps to raise the total electricity consumption in private households.The remaining 60-70 % of the variation in household consumption may be explained by the families' soft values and attitudes. Through qualitative interviews and questionnaires, the project has been shown that households with relatively low power consumption typically pay attention both by purchasing electrical appliances and in their daily use of them.
Consumer motivation to save is often a combination of environmental and commitment to their own economy. Many of the consumers who are good at saving, says that they are taught to conserve resources and more or less unconsciously took these habits from childhood.
The results suggest that campaigns for private households should involve both the conscious energy savers (to maintain their low consumption) and motivated, who just cannot get something done about it in practice. The analyzes also show that electricity is used very differently. Families spend a relatively larger proportion of laundry, drying and washing, while older and single people have a relatively higher consumption for cooling/freezing and lighting. Information and communication technology represents a significant part of the electricity used in all types of households.
There is especially a big difference in standby use. Some households have almost no standby consumption because they deliberately turn off appliances after use, and because they have fewer electrical appliances. Other families spend up to 15-20 % of their total electricity consumption in standby.
