Germany has made considerable progress in its transition to a sustainable energy system. But how can we ensure that the transformation of our energy systems is sustainable in its social, ecological and economic dimensions? This question is the focus of the Korpernikus research projects, a major research initiative launched by Germany’s Federal Ministry of Education and Research. The IASS project “Energy Transition Navigation System” approaches the energy transition as a process of broad societal transformation. The project will investigate the respective roles of technological, economic, political, and social systems within the energy transition and develop options for their integration within this process. In doing so, the project will foster the development of new business models.
