Extended risk and benefit evaluation of energy systems for policy analysis

The social compatibility of future energy scenarios is analysed in order to improve the political decision making. Social compatibility analysis is a form of technology assessment focusing on societal and social issues. The value tree analysis method is applied to collect and structure the values and concerns of important societal groups. Nine relevant groups and organizations in the society of the Federal Republic of Germany are included in the study. A combined value tree is formed by integration of the individual value trees. The overall value tree is transformed into an operational and systematic catalogue of criteria. Measurement instructions and scales are introduced as indicators for the extended risk and benefit evaluation of energy systems. The assessment of specified future energy options is performed by selected scientific experts. The results can improve the political decision-making process with respect to societal needs and desires. (author)
