EnSu presentations at the ECEEE

At the Summer Study of the European Council for an Energy Efficient Economy (eceee), which took place in France in June 2024, EnSu members Carina Zell-Ziegler, Johannes Thema and Alexander Kling gave a total of 4 presentations. The positive feedback in the discussions showed that EnSu research on the topic of energy sufficiency is relevant and can close existing research gaps. The exchange with many other conference participants from research and practice, including at a co-organized “informal...

our research interest


How can energy sufficiency be defined and distinguished from other strategies?


What hinders the implementation of sufficiency policies and measures?


What characterizes successful transformation strategies which encompass energy sufficiency?


How can the effects of succiciency be described, evaluated and quantified?


Which multiple effects of energy sufficiency measures can be described (quantitatively and qualitatively)?


How can energy scenarios be developed in inter- and transdisciplinary processes?

The Ensu Team

The junior research group “The role of energy sufficiency in energy transition and society” (EnSu) will systematically include sufficiency strategies in energy system modelling and discuss the current and necessary societal frame conditions for establishing energy sufficiency strategies.



How can energy consumption decrease in absolute terms?


How can societal change be integrated in energy modelling?


These questions are in the center of the research activities of the junior research group “EnSu – The Role of Energy Sufficiency in Energy Transition and Society” that started in May 2020. The project is funded by the German federal ministry for education and research (BMBF) within the research framework for sustainable development (FONA).


Six junior scientists working at the Öko-Institut (Freiburg), the Wuppertal Institute for Climate, Environment, Energy and at the Europa University Flensburg (EUF) aim at studying the transformation processes of society in the context of the Energiewende and making the insights applicable to energy system modelling.
