This research focuses on public attitudes toward nuclear energy in the context of reaching consensus on energy solutions for climate action. Using the Social Identity Approach, it analyzes how social groups shape opinions, with a spotlight on Germany and France. Political affiliation, age, socio-economic status, and gender are key identity factors. The study employs an agent-based model, revealing that discussing nuclear energy within multiple identity contexts promotes consensus and depolarization. The findings underscore the significance of social identities and context in shaping opinions, transcending the nuclear energy discourse to advocate for inclusive discussions in decision-making processes. Future research can delve into social influence, ongoing debates, and additional factors to comprehensively understand nuclear energy attitudes.
