This paper examines the role of the wave energy sector in Ireland using theories from the field of Science and Technology Studies (STS). Theoretical divisions within the field of STS are examined, particularly the Sociology of Scientific Knowledge (SSK) and Actor-Network Theory (ANT). Any conflicts which these two theories present to each other are examined through the empirical findings of the Irish wave energy sector. In particular, ANT s rejection of macro and micro distinctions when analysing society are compared to SSK s identification of causality in the creation of scientific knowledge and technology. ANT s network outlook was later built on by a new SSK concept called co-production and this is also examined in light of empirical findings. In addition, ANT s theoretical and methodological concepts are applied in the empirical investigations of this thesis. The network approach provides a holistic outlook and helps to explain the various links within the wave energy network. Government White Papers, academic articles, websites and interviews are used in painting a broad picture of the Irish wave energy sector. This is then applied in answering the empirical research question: What needs to be done in order for wave energy to be successfully implemented in Ireland? The use of ANT shows that there are many forces at play in the Irish wave energy network, both positive and negative, and these have been crucial in plotting the path of this young and still developing sector. Empirical findings show that SSK and ANT can both be validated in analysing technological systems.
