History of different energy sources (eg. wood, fossil energy, electrical energy) and their social production, use and perception; conflicts in this realm (e.g. construction of power plants); history of electrification; socio-ecological works with the concept of social metabolism (energy flows).

Before the construction of the danube power plant "Abwinden-Asten", evidence of the existing fishing conditions in the area of the future plant was recorded. Since possible claims to damages by the fishery necessitate proof of an interruption of fish-migration, a marking of fish was made and on the basis of marked fish that were caught again, migrations were registered of certain fish species in the region in which evidence about fish was to be established.
