Description of the work packages

AP MCT: Methods – Coordination – Transdisciplinarity

The aim of this work package is to maintain an ongoing dialogue within the research team (interdisciplinary level) and with the practice partners (transdisciplinary level) about conceptualities, methods and the appropriate differentiation of the object of study. Several Workshops (WS) that will take place in the ZEW in Mannheim are used to integrate practical knowledge in the project.

AP 1: Case studies

In this work package, case studies of lighting, mobility and heating are used to analyse the social-psychological and sociological aspects of possible rebound effects. In this context, relevant questions for a large scale survey shall be found. Focus groups interviews (at ca. 10 persons) will be carried out for each of the three case studies. For this, persons who have recently bought an energy-efficient car or have taken efficiency measures will be chosen.

AP2: Econometrical analysis of existing datasets

In this work package, new insights into rebound effects are gained by applying existing datasets. Estimates of the indirect rebound effect can be derived from data of private consumption provided by the SOEP (German Socio-Economic Panel). Another large data base used is the German Mobility Panel (MOP) which contains information on availability of cars, characteristics like engine size or age of cars, driving behaviour, mileage and since recently household income. By utilizing these means, we can improve the few estimations of the direct rebound effect for the car traffic in Germany there are so far. Furthermore we use the representative survey about the energy consumption of private households, which has been commissioned by BMWi twice and has been carried out by RWI and forsa. It provides enough data to estimate the responsiveness of households to increases in energy prices. Consequently, the direct rebound effect for the use of energy-saving lamps can be quantified.

AP3: Elicitation and analysis of new datasets

In this work package, a survey is conducted based on the results of the focus groups (AP1) and the insights of the analysis of existing datasets (AP2). The resulting data is examined with regard to eventually existing differences in the energy consumption dependent on the life style types that have been identified in AP1. Furthermore, the findings on the psychological mechanisms when rebound effects are observed shall be supported by a broad data basis. After that rebound effects are analysed econometrically.

AP 4: Macroeconomic analysis

In this work package, macroeconomic rebound effects are analysed based on the preliminary research of the preceding work packages. In order to do so, the computable general equilibrium (CEG) model PACE which has been developed by ZEW will be refined. This allows to cumulatively include the different mechanism of the rebound effect and, therefore, to model the demand behaviour of households as well as the social dimension of the rebound effect. The aim of the model development in AP4 is to increase the closeness to reality and relevance for policy in the investigation of the macroeconomic rebound effect.   

AP5: Measures to minimize rebound effects

In this work package, the instrument of the Delphi-method is used to acquire and evaluate effective, efficient and socially acceptable measures to reduce rebound effects. It is suggested to conduct a two day panel of 16 experts (e.g. energy-supplier, -producer and -trader, energy agencies, politicians and researchers). In the course of the panel, a combination of economic, social and educational instruments is considered. 

AP 6: Project Management

In order to exchange approaches and results regular project meetings will be organised which also will be used for preparing workshops with the practice partners. Moreover, the project management is responsible for the administration of the project, keeping contact with the project initiators, the external presentation (including status seminars), on schedule submission of project reports and appointments as well as the creation and maintenance of a project website.
