Scientific paper contribution: An interdisciplinary understanding of macro rebound effects
Abstract: This paper, delivered to the special session about rebound effects “Energy, Efficiency, and Growth - Analyzing Rebound Effects“, addresses three different positions found within the rebound debate to explain what causes rebound effects at the macro level. It outlines an energy-economic perspective in which the actors, consumers and producers in the market adjust to lower energy prices by producing and consuming more than they did before the efficiency improvement. It then addresses how rebound effects have been understood in light of evolutionary theory and thermodynamics, in which it is key that society is under constant development and that there are two forms of efficiency: energy efficiency and time efficiency. There has been a preference for time efficiency, that is, for increasing the speed of consumption and production society wide. Finally, by applying a critical-realist perspective, it looks at how social science has dealt with rebound effects at various levels.
