These problems pose great challenges to human beings in pursuing the development of environment, energy, and sustainable survival; thus, sustainable operations for the environment and conservation consciousness have come to be valued (European commission, 2005; Halme, 2004). Urban energy use is currently an essential issue widely investigated overseas. According to the aforementioned research background and motive, stratified sampling is employed in this research and field questionnaire is conducted based on the proportion of the population of each city and county to their household numbers in order to obtain the data including the income, number of family members, the size of the house, and the power consumption habit. Concretely speaking, the objectives in this research are as follow: 1. To apply DEA to the comparison of household power consumption efficiency in the five municipalities; 2. To compile domestic and overseas power consumption indicators in which congruous efficiency indicator is suggested through the correlation analysis by means of DEA. Preface Result Conclusions Stratified random sampling is employed with 1,000 households comprising the total number of observations in this questionnaire which include questions about basic data, residential properties, family properties, and household electrical appliance use. The research demonstrates that although in Taichung City and Tainan City, the inputs are the smallest, the outputs are relatively smaller as well. The questio
