The results showed that: variables including number of the household members, household type, household income, having elderly or not, gender and age correlated with EUB significantly. The study also found that the elderly had a significant positive impact on household energy conservation. Household income showed the polarized differences on EUB. EUB of female residents and young residents were more reasonable and low-carbon.
