Ireland is facing a great challenge in meeting renewable energy requirements, where due to past circumstances and decisions, the nation state is now heavily dependent on imported fossil fuels. Given the contribution of these imported fossil fuels to global climate change, price instability and supply insecurity, Ireland is under a pressing need to face up to the dilemma of an unsustainably fueled economy. This thesis explores how the EU policy process is helping Ireland to achieve the goals it has set with the EU and how these are being incorporated into the drivers of wind power development in Ireland. This research sought to uncover the dynamic of this relationship - the goodness of fit - through an assessment of three mechanisms of change, namely: Discourses, Directives and Finances, which were drawn on from the theoretical approach of Europeanisation. By doing a combined assessment of these three channels and their influence, this thesis provides a greater understanding of the ways in which the development of wind power in Ireland is influenced by the EU level. The thesis finishes with a concluding discussion on the importance of the national level in this process, as well as the importance of social and community engagement, which despite being previously seen as important, has to date largely manifested as a tokenistic gesture in Ireland. This thesis reasserts it as a common and crucial thread of the renewable energy transition that continuously arose as being pre-eminent during this study.
