Society, Technology, and the Sustainable Provision of Electricity A sociotechnical perspective on developing energy infrastructure Seth Townley Master thesis in Culture, Environment and Sustainability Centre for Development and Environment UNIVERSITY OF OSLO June 2016 © Seth Townley 2016 Society, Technology, and the Sustainable Provision of Electricity: A sociotechnical perspective on developing energy infrastructure http://www.duo.uio.no/ Print: Reprosentralen, University of Oslo II Abstract A direction which sustainable development in energy systems could take is towards electricity ‘co-provision.’ Here, centralised fossil-powered generation is partly replaced by decentralised, renewable micro generation infrastructure supplementing a leaner, more dynamic national grid fuelled by diverse range of sustainable power sources. Pursuing this path would require a major overhaul in existing technical systems of energy provision. The common theme which runs through much of the diverse literature on technology change emphasises the sociotechnical nature of change processes, which is to say that it treats technology and technical systems as the material embodiment of social choices. This means that the process of developing energy infrastructure into a sustainable system of electricity co-provision cannot simply be ‘enabled’ by technology, conceived of as an exogenous variable ‘impacting’ society. It is, in fact, a process of endogenous societal change: a sociotechnical transition. This thesis examines the dynamics of this transition with regards to electricity co-provision. In doing so, it presents and seeks to problematize simplistic discourses on technology change, and to draw back from the narrow conception of technical innovation found in these discourses. It analyses existing systems of energy provision alongside individual energy project case studies, which represent novel sociotechnical configurations of artefacts, institutions, and actors in electricity co-provision experiments. It applies sociotechnical transitions theory and its multi-level perspective in order to link the micro and the macro levels within this analysis. The thesis attempts to highlight both the promise in the emerging configuration of co-provision technologies and actors, but also the doubt that hangs over any vision of a sustainable sociotechnical transition. To do this it draws attention to the multiple paths along which sociotechnical change could unfold, but which are ‘closed off’ by a number of predominantly political factors. It is shown that, ultimately, the future shape of technical systems is not simply a question of technology but of social choice. Trying to better understand who is able to influence these choices, and who is locked out of the process, is an important area of enquiry in environment and development studies. This thesis aims to contribute to this area of enquiry, specifically as it relates to the sustainable provision of electricity. Key words: electricity co-provision, sociotechnical transition, sociotechnical configurations, innovation trajectories/ pathways, sustainable development III IV Acknowledgements I would like to extend sincere thanks my supervisor, Desmond McNeill, whose patient guidance has been invaluable as this thesis, falteringly at first, has taken shape. Also, to my partner, Katy, for graciously putting up with my now year-long obsession with the esoteric minutiae of sociotechnical energy systems, and for always supporting everything I do. Thanks also to Gudrun Helland, our fantastically supportive study coordinator at SUM, for cheering me and everyone else along and always being on hand to answer questions; Tanja Winther for taking time to discuss my early project proposal with me; Andy Edwards of Bioregional for talking to me before my idea was even an idea, but helping me to make contacts necessary for my fieldwork all the same; and to all of my informants for taking the time to share their knowledge and expertise. And last, but most certainly not least, I want to thank all of my fellow SUM master’s students who have shared this experience with me. Completing this thesis has been somewhat of an emotional rollercoaster, but I have only very happy memories of all the lunches and coffee breaks we have taken together along the way.
