Deliberating and communicating the potential of fusion power based on long-term foresight knowledge

The main aim of this contribution is to provide guidance (in terms of quality criteria) for setting up foresight exercises as a platform for discussion and communication of the benefits and drawbacks of fusion with a broad range of stakeholders. At the same time, we explore conditions that might enhance the resonance of such foresight exercises in the policy sphere. In order to address this dual aim, we first introduce a philosophical framework called 'constructivism'. Next, we give a constructivist reading of scientific foresight as a combined scientific-political practice and point out some of the main points of interest regarding the relationship between foresight knowledge and policy. We illustrate these points of interest with practical case-study examples. Finally, we draw upon our theoretical and case-study research to propose some points of particular interest for the fusion community wishing to develop long-term energy scenarios.
