The political debate on the sustainable transformation of the energy system often focusses on the aspects of climate protection and associated expenses for private households and the industry. Other aspects such as resource demand, social acceptance or life cycle emissions of pollutants are often neglected. However, these issues have to consider in relation to transform and control by political measures towards a sustainable energy system.

The goal is the development of a new generic modelling and assessment approach for energy scenarios which allows a multicriteria assessment and optimization of technically and structurally feasible development pathways of the energy system in Germany. Assessment criteria include economic, ecologic and social indicators.

The project partners pursue the following aims:

• Development of an interdisciplinary, integrated method for the sustainability assessment of transformation scenarios for the (German) energy system. Economic, ecologic and social aspects will be taken into account through a coupling of models, methods and competences of the project partners.
• Analysis and comparative sustainability assessment of a spectrum of relevant transformation scenarios for Germany
• Optimization of capacity expansion in the power sector under consideration of ecological, economic and social sustainability aspects
• Identification and analysis of conflicting goals and trade-offs between different sustainability indicators which will occur during the transformation process
• Formulation of conclusions for energy policy and society with respect to alternative courses of action
