a b s t r a c tA growing body of literature has examined the dynamics of wind energy development across different mature and emerging institutional contexts. However, so far only few have paused to reflect on the differences between developed and emerging economies. Building upon the literature on institutional entrepreneurship, this paper compares institutional strategies in wind energy development in Finland and India by using the typology of political, technical and cultural work. We highlight the role of institutional approaches in studying sustainable energy transitions in mature and emerging institutional contexts, while being sensitive to the role of heterogeneous actors in shaping institutional arrangements. Our findings offer implications for debates in the institutional entrepreneurship literature by exploring how actors shape their institutional environment in different contexts, and the extent to which emerging institutional contexts provide more opportunities for institutional entrepreneurship. Finally, this paper underscores the need for developing insights into enabling conditions for successful collective institutional entrepreneurship and for developing typologies of institutional strategies which are generalizable across both mature and emerging institutional contexts.
