Theoretical perspective on rebound effects from a social science point of view: Working paper to prepare empirical psychological and sociological studies in the REBOUND project

The replacement of appliances and other energy using products by more efficient ones is generally regarded as an effective strategy to reduce energy demand. However, the savings realized by this strategy may be lower than those theoretically expected or calculated from a technological point of view due to changes of behaviour following the acquisition. This phenomenon is known as the rebound effect. While scientists generally agree on the existence of rebound effects, size, relevance and explanations of such effects are controversially discussed. This paper discusses concepts to explain rebound effects from a psychological as well as sociological point of view. In particular, an approach which combines variables from psychological action theories with the sociological life-style concept is suggested as a framework for studying determinants of rebound effects.
