How can households be motivated and encouraged to use energy efficiently, to adapt their electricity consumption flexibly to the available supply of renewable energy sources, and to consider energy efficiency as a central criterion in purchasing and investment decisions?
In this project, interventions will be developed specific to target groups and contexts that will support energy efficient and time flexible behavior. Intervention techniques will be evaluated with respect to how they work and with respect to long-term effects.
The intervention techniques will be developed against the background of psychological and economic action theories and findings from intervention research studies. They will take into account the results of project “Determinants of decisions and behavior in households”. They include new aspects of the future energy infrastructure like smart meter in their conception

Several subprojects are planned:

In one of the sub-projects, variants of websites, which supplement smart meters, will be developed and evaluated with the aim to motivate energy-efficient and time-flexible electricity consumption and to encourage pertinent behavioral change. In two studies, the focus is on action-orientated information. In a first study the effectiveness of device-specific, evaluative feedback in combination with individualized recommendations will be investigated. In a second study, the focus will be on the effectiveness of pre-senting information in such a way that users are guided from the initial formation of an intention to act to action planning and, finally, action execution.

Another sub-project will develop target-group-specific interventions to promote energy saving in two and more-person households. The study aims at understanding family cooperation and the specific needs of adolescents. Long term development and changes of environmental and energy relevant attitudes in adolescents will be investigated.

Furthermore, an analysis of existing incentive programs in the area of energy efficient, intelligent household appliances from a psychological perspective and decision making research (e.g. prospect theory) will be conducted, program alternatives will be tested and recommendations for the design of incentive programs will be developed.

Finally, an economic field experiment will investigate to what extent the decision to invest in heating or insulation equipment is influenced by information and advisory services of energy consultants.
