Abstract [en]

The European Union is implementing the eco-design directive, which means for example a phaseout of inefficient equipment, such as those with stand by-function or lamps with a low lumen/Watt-ratio. How much energy will be saved from this? The Swedish Energy Agency has collected detailed measurement data from 400 households in Sweden. Based on that, and on interviews and visits, savings potentials in the use of lighting have been estimated. Possible reductions are quite big, but very diverse. Realistic estimations can be reached using real householders possession and hours-of-use of lamps and stand by-functions. In the case of lighting two levels of reduction will be estimated and discussed: one level when incandescents are replaced by CFLs, and another when they are replaced by LEDs. The latter, however, may be associated with rebound effects since a whole new repertoire of lighting design opens up. Social change can both promote and counteract energy savings in residential electricity use. Consumption differs between different types of households, and the household structure is changing in many countries. Based on quantitative data from Sweden the following differences will be addressed: Are female householders more thrifty than male? Single person households will be compared. This is of interest for the future if women continue to get a more economically autonomous position in many countries. Do single person households consume more energy per person than others? Presumably this is so since co-use of electric equipment is lost when the number of people decreases in the average household. This is a tendency counteracting energy savings due to eco-design directives, and of interest if single living is becoming more common in many countries. Do pensioners have a lower consumption than younger people? This is not obvious. Older people may combine a thrifty lifestyle with older equipment. This is of interest for the future since the elderly is a growing part of the population in many countries, and whether the thrifty lifestyle depends on lower income for pensioners, or on habits acquired during earlier years. If the latter is correct the thrifty lifestyle may disappear with coming generations of pensioners that has become used to a high consumption level.
