This dissertation asks how inhabitants of a sustainable village are living out Germany’s transition from nuclear to renewable energy. The sustainable village remains a locus of optimistic attachments for renewable energy advocates, who argue that a decentralized power grid will enable people to more directly participate in power production and politics as “energy citizens.” Yet while rural areas have become sites of speculation, innovation and growth, few rural-dwellers are enfranchised in (or profiting from) the technoscientific projects in their midst. I draw upon 13 months of fieldwork in a northern German village transformed by wind turbines, photovoltaics and biofuels to consider why, asking what kinds of public life flourish in the absence of democratic engagement with renewable technologies. This ethnography engages the village as multiply constituted across domains of everyday life, including transit, farming, waste management, domestic life, and social gatherings. I found that environmental policy, everyday practices, and the area’s material histories combined to produce ontologies—senses of what exists—that circumscribe citizen participation in the energy sector, affording more formal opportunities to men than to women, and privileging farmers’ interests in plans that impacted the larger community. These findings illuminate how many villagers become ambivalent toward the project of the energy transition and disenfranchised from its implementation. Yet many who were excluded from formal participation also engaged with renewable technologies as they sensed out their worlds, using tropes of sustainable energy and technoscientific materials to place themselves in this emerging energy polity. Their everyday worldmaking brimmed with what I call unruly energies, structures of feeling that registered more as affects than as discourse. In the village, these took form as sensory disturbances, disquiet among neighbors, technoscientific optimism and skepticism toward environmental policy. These affective modes of attention, investment and participation were vital aspects of public life that shaped the transition’s unfolding. They exceeded liberal models of renewable energy citizenship, which presume that socioeconomic interest and environmental commitment are universal among citizens. In this way, unruly energies compel more nuanced attention to the multiple, contingent, site-specific ways in which citizenship takes form in the making of eco-capitalist energy infrastructure. / text
