Renewable energy is one main foci regarding climate polluting materials produced by fossil fuels. Additionally, research related to carbon capture and storage (CCS) is part of the research undertaken at the IGCS. The relevance of the cross-cutting areas of particularly environmentalism, environmental technology and resource efficiency. Similar to the other research areas, the field of energy is supposed to be interlinked with some sub-topics of the other four key areas. Examples are water resources in urban areas and land use, as well as to the sub-topic waste management and renewable energy.
