This paper trials the use of q-analysis as a data analysis method to investigate what are the constraints to sustainability for the UK offshore wind industry. q-analysis is used to remove the indeterminacy of an interpretive case study methodology when trying to identify bottlenecks to sustainability. In the sample case study used in this paper, factors exogenous to the industry and its supply chains are shown to be the bottleneck, revealing a case where a lack of interest in sustainable consumption is the constraint to achieving sustainable production.
