Social and engineering determinants and their equity implications in residential electricity use

Energy conservation may occur because of either economic constraints or voluntary changes in values and lifestyle, with quite different social welfare implications. We examine the determinants of summer electricity use in single-family dwellings. Income and household size strongly affect energy use, while factors related to values and lifestyle are less important. A causal model approach is used to show how the social variables are related to energy use through intervening engineering/hardware variables.
