Exploring energy sufficiency: New challenges and options in times of crisis.

The war in Ukraine has made the fatal dependence of many countries on energy sources from non-democratic countries extremely clear. How should politics and society react to high energy prices and the necessary ban on imports of fossil fuels from Russia? Can modern societies get along with much less energy? This Op-Ed article by Benjamin Best, Michaela Christ, Tilman Santarius and Frauke Wiese Energy in the Journal for Technology Assessment in Theory and Practice argues that the concept of energy sufficiency can play an important role in answering these questions. The article explores sufficiency as a interdisciplinary research topic for energy modelling, scenarios and policy.
