Residential energy expenditures and the relevance of changes in household circumstances
分析了住宅特征、家庭成员特征和行为对人均能源支出的影响，发现家庭规模变化是能源支出变动的最主要因素，而社会经济特征影响较小。
This paper analyses the impact that dwelling characteristics and characteristics and behaviours of household members have on per capita energy expenditures. It also analyses whether changes in household socio-economic circumstances translate in changes in energy expenditures. Socio-economic characteristics have a moderate impact, while dwelling characteristics and especially household size have much larger impacts. The largest changes in energy expenditures are due to changes in household size. The recent socio-demographic trends will make it harder to design policies to effectively reduce the carbon footprint of a country, while policies influencing cohabitation and family size may have positive indirect effects.
