Swiss energy policy posits an energy system without nuclear power. The Swiss energy research landscape is expected to develop new technologies that contribute to meeting the challenges associated with filling the energy gap. This research programme aims to contribute social science research and knowledge to a sustainable energy transition that implements the new Swiss energy policy. It addresses three key challenges of the transition: international and global dimensions of energy research; transdisciplinary energy research; and the involvement of the social sciences in the energy transition. The programme objectives are to develop hands-on, use-inspired social science knowledge, tools and solutions for various stakeholder groups in the Swiss energy system.
