Policy HighlightsTo achieve the recommendation stated in the chapter title, we propose the following: Policymakers should mandate that energy decision-making processes be more inclusive, supporting both geothermal representation in large-scale energy deliberation and the inclusive engagement of local communities in individual geothermal projects. Policymakers should foster inclusive societal engagement that goes beyond the minimal requirements of consulting and informing at planning stage, to incorporate processes of deliberation and co-creation with local communities. Geothermal industry actors should practise inclusive societal engagement which is early, continuous, and sensitive to the technical specificities (e.g. local resource, subsurface uncertainties) and social challenges (e.g. low public awareness) of geothermal technologies. Language alignment activities and mutual expert elicitation can support the exchange of knowledge across social-technical disciplines, bridging disciplinary siloes to tackle the problem above.
