However, there are still multiple barriers that make the socially optimal level of adoption a complex target to achieve. Over the past three decades, the debate on how to encourage EE has been guided by the physical–technical–economic model, which has a strong focus on devices and costs, and in which human behaviour has been seen as a trivial factor. Fortunately, the advent of a new causal framework to model citizens’ behaviour (behavioural economics) has started to enable the integration of the human factor into many policy areas, including EE. However, this integration is only in its infancy. This report aims to further stimulate the policy integration of the human factor by providing policy actors, who are interested in encouraging citizens’ decisions to invest in EE, with key conceptual and practical insights from four examples of energy-related social sciences (economics, behavioural economics, psychology and sociology). }, title = {Mobilizing citizens to invest in energy efficiency }, type = {Technical guidance}, url = {}, doi = {10.2760/137315 (onl
