The aim of this master thesis is to analyse socio-technical energy scenarios in the energy sector in order to find out if, which, and to what extent sociological dimensions and concepts are contained in these energy scenarios. For this purpose a qualitative content analysis according to Philipp Mayring was conducted. As a basis for the master thesis, for the theoretical background four subject areas are highlighted, namely first the current energy issues in the societal contexts, second the emergence and development of future studies as science, third scenario technique as method of future studies, and forth the question of how social science and in particular sociology are dealing with future studies. For instance, energy economics, changes in the energy system, usage of different energy sources or the future energy supply are topics that are dealt within energy scenarios that have been chosen for the qualitative content analysis in this thesis. Processes of change within the energy sector are also strongly connected to social changes, and thus, socio-economical aspects are included more and more in these scenarios. In general one can say that there are structured descriptions of a future society within these energy scenarios. One main result of this qualitative analysis was that economical as well as political dimensions are included the most. Other sociological dimensions or concepts like values, or the orientation of consumption as well as demographical trends are included to a lesser extend. However, on the whole, these energy scenarios are written in a too reductionistic way in order to find a concrete hint that sociological concepts and theories are explicitly included.
