For the energy transition in Germany to succeed, the energy system must be redesigned: On the one hand, many decentralized actors must be integrated, both technically and organizationally. On the other hand, the newly emerging polycentric energy system must be designed in a sustainable way - in other words, higher-level rules should focus on ecological, economic and socially just implementation. How do current framework conditions and institutions have to change for this? In six qualifiying theses, the SteuerBoard Energie junior research group is investigating how digital applications can support this change process and what kind of financing options are available.
