Over the coming decades the Highlands and Islands of Scotland will be transformed as new technologies and infrastructures are installed to exploit wind, wave and tide power.However, interactions between the region -understood as a sociospatial category shaped by history, culture and institutions -and these technologies are poorly understood and need to be appreciated in more detail before the changes gather momentum. In this paper we link and extend research around socio-technical transitions and resource peripheries and use this framework to analyse wind energy projects on the island of Lewis. Our analysis draws attention to transition-periphery dynamics and the ways in which renewable energy projects and particular locations are co-shaping each other through these. Building on this case study we suggest implications for the region as a whole, argue that the analytical-normative agenda of socio-technical transitions should be recast, and highlight the need for more research on socio-technical transitions and new resource peripheries.
