This study analyzed the determinants of residential electricity efficiency in Korea where the importance of electricity demand management in households is increasing. According to empirical analysis result, the increase in income or the decline in the electricity price leads to the inefficiency of residential electricity consumption. Also, as the number of elderly households increases or the number of households residing in apartments increases, the household electricity efficiency improves. On the other hand, the increase in one-person households was found to have a negative effect on the electricity efficiency improvement. It is confirmed that the increase of cooling demand has a little effect on residential electricity efficiency, but the increase in heating demand results in deterioration of residential electricity efficiency. Therefore, improving the efficiency of both heating equipment and residential buildings heating means helping to improve the electricity efficiency of total households. Also, it implies that the policy to improve electricity efficiency should be further strengthened for non-apartment housing.
