Norway is committed to promoting the use of energy from renewable sources and, as such, has established policies to facilitate the long-term development of the land-based wind power sector. Wind power installations, however, are often sited in remote areas where wind resources are attractive but where the environment remains relatively untouched. This has lead to an impassioned debate about the acceptability of wind power installations in Norway’s natural landscapes. Due to a long history of democratic local governance, wind power projects in Norway are unlikely to be approved unless they have local support, giving host municipalities an unofficial veto power over the outcomes of such proposals. This makes the ways that public and private stakeholders influence local attitudes and beliefs crucial to the outcome of licensing decisions. According to research published by Inderberg et al. (2019), NGOs represent a marginalised stakeholder group in Norwegian land-based wind power licensing processes and are considered unlikely to have any chance of stopping a project. In the time since their research was published, however, Norway’s national debate reached a fever pitch, with significant nationwide opposition mobilising both on- and offline, eventually leading to Norway’s national framework for wind power being abandoned. Several high-profile NGOs took clear oppositional stances in the debate, conducting a range of activities including the dissemination of oppositional media, the organisation of demonstrations, and the submission of objections in official wind power licensing procedures. To understand the capacity of such voices to affect land-based wind power licensing decisions, both directly at the local scale as well as indirectly through their influence in the national debate, my research investigates the persuasive influence of narrative messaging from Norway’s largest outdoor organisation, Den Norske Turistforening (DNT), on both supportive and oppositional stakeholders in a land-based wind power licensing process in Larvik, Norway. The findings of this research suggest that ongoing processes of narrative persuasion work to amplify the existing positions of members of local government – engaging those who hold story-consistent attitudes and beliefs, whilst repelling those whose do not – ultimately contributing to the polarisation of the debate about the acceptability of land-based wind power in Norway.
