This chapter sketches out a particular case in which the “values” of a World Heritage Site (WHS) in Scotland became entangled in competing discourses relating to political and moral economies in the context of a case around cultural and historic “sustainability.” In a number of public meetings, media statements and during an official Scottish Government inquiry in 2008, different social and cultural groups debated whether to approve or deny a planning application to construct a wind farm that would provide a substantial output of renewable energy, but which would be sited within view of the Heart of Neolithic Orkney (HONO) WHS, inscribed by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) in 1999. Utilizing ethnographic approaches drawn from material culture studies in anthropology and archeology, I examine the ways in which social actors on both “sides” of the conflict articulated arguments about its value as a community “commons” and the ways in which it could provide forms of social capital for Orkney communities, both in relation to its “aesthetic” properties as an authentic cultural landscape, and as a potential site for the symbolic and actual production of a form of sustainable energy.
