    This paper focuses on arguably the single most striking contrast in contemporary major energy politics in Europe (and even the developed world as a whole): the starkly differing civil nuclear policies of Germany and the UK. Germany is seeking entirely to phase out nuclear power by 2022. Yet the UK advocates a ‘nuclear renaissance’, promoting the most ambitious new nuclear construction programme in Western Europe.Here,this paper poses a simple yet quite fundamental question: what are the particular divergent conditions most strongly implicated in the contrasting developments in these two countries. With nuclear playing such an iconic role in historical discussions over technological continuity and transformation, answering this may assist in wider understandings of sociotechnical incumbency and discontinuity in the burgeoning field of‘sustainability transitions’. To this end, an ‘abductive’ approach is taken: deploying nine potentially relevant criteria for understanding the different directions pursued in Germany and the UK. Together constituted by 30 parameters spanning literatures related to socio-technical regimes in general as well as nuclear technology in particular, the criteria are divided into those that are ‘internal’ and ‘external’ to the ‘focal regime configuration’ of nuclear power and associated ‘challenger technologies’ like renewables. It is ‘internal’ criteria that are emphasised in conventional sociotechnical regime theory, with ‘external’ criteria relatively less well explored. Asking under each criterion whether attempted discontinuation of nuclear power would be more likely in Germany or the UK, a clear picture emerges. ‘Internal’ criteria suggest attempted nuclear discontinuation should be more likely in the UK than in Germany– the reverse of what is occurring. ‘External’ criteria are more aligned with observed dynamics –especially those relating to military nuclear commitments and broader ‘qualities of democracy’. Despite many differences of framing concerning exactly what constitutes ‘democracy’, a rich political science literature on this point is unanimous in characterising Germany more positively than the UK. Although based only on a single case,a potentially important question is nonetheless raised as to whether sociotechnical regime theory might usefully give greater attention to the general importance of various aspects of democracy in constituting conditions for significant technological discontinuities and transformations. If so, the policy implications are significant. A number of important areas are identified for future research, including the roles of diverse understandings and specific aspects of democracy and the particular relevance of military nuclear commitments– whose under-discussion in civil nuclear policy literatures raises its own questions of democratic accountability

    Multi-criteria decision making with linguistic labels: a comparison of two methodologies applied to energy planning

    Get PDF
    This paper compares two multi-criteria decision making (MCDM) approaches based on linguistic label assessment. The first approach consists of a modified fuzzy TOPSIS methodology introduced by Kaya and Kahraman in 2011. The second approach, introduced by Agell et al. in 2012, is based on qualitative reasoning techniques for ranking multi-attribute alternatives in group decision-making with linguistic labels. Both approaches are applied to a case of assessment and selection of the most suitable types of energy in a geographical area.Peer ReviewedPostprint (published version

    Innovation in Concentrating Solar Power Technologies: A Study Drawing on Patent Data

    Get PDF
    Better understanding the innovative process of renewable energy technologies is important for tackling climate change. Though concentrating solar power is receiving growing interest, innovation studies so far have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and solar thermal technologies. This study relies on patent data to examine international innovative activity in concentrating solar power technologies. Our unique contribution, based on engineering expertise and detailed datawork, is a classification system matching solar thermal technologies to the International Patent Classification (IPC) system. To this end we suggest a narrowly defined set of IPC classes and a broader one of technologies relevant to CSP, but not exclusively so. We moreover exploit information from three international patent offices, the European, the United States and the Japanese patent office. Innovative activity in narrowly defined CSP technologies has experienced an early boom before 1980 and only recently showed some signs of more activity - a pattern closely resembling the R&D support path. R&D and innovation are concentrated in few high-tech countries - such as the U.S. or Germany. Large CSP potential is not a sufficient condition for innovation, only developed countries such as Australia with both CSP potential and adequate economic and scientific capabilities are found to be among the group of relevant innovators.Innovation, patent data, solar technologies, climate change

    The introductory astronomy course at the University of Cape Town: probing student perspectives

    Full text link
    We report on research carried out to improve teaching and student engagement in the introductory astronomy course at the University of Cape Town. This course is taken by a diverse range of students, including many from educationally disadvantaged backgrounds. We describe the development of an instrument, the Introductory Astronomy Questionnaire (IAQ), which we administered as pre- and post-tests to students enrolled in the course. The instrument comprised a small number of questions which probed three areas of interest: student motivation and expectations, astronomy content, and worldview. Amongst our findings were that learning gains were made in several conceptual areas, and that students appeared to develop a more nuanced view of the nature of astronomy. There was some evidence that the course had a positive impact on students' worldviews, particularly their attitudes towards science. We also identified a promising predictor of course success that could in future be used to identify students requiring special teaching intervention.Comment: 19 pages, 2 figures.

    The justification, economic and technological benefits of NASA Space Programs (aside from pure scientific objectives), in improving the quality of life in the United States is discussed and outlined. Specifically, a three-step, systematic method is described for selecting relevant and highly beneficial payloads and instruments for the Interim Upper Stage (IUS) that will be used with the space shuttle until the space tug becomes available. Viable Government and private industry cost-sharing strategies which would maximize the number of IUS payloads, and the benefits obtainable under a limited NASA budget were also determined. Charts are shown which list the payload instruments, and their relevance in contributing to such areas as earth resources management, agriculture, weather forecasting, and many others

    Eighth National Garrett Morgan Symposium on Sustainable Transportation, Report MTI 08-03

    On April 1, 2008, the Mineta Transportation Institute at San José State University hosted a videoconference that brought together experts in surface transportation and students from middle and high schools across the nation to discuss the importance of sustainable transportation. The goal was to introduce students to future career opportunities in transportation and to inspire them to take the high school and college courses that will prepare them for professional careers. Students from California, Maryland and Virginia participated in the 2008 symposium, during which they heard opening remarks from Vice Admiral Thomas J. Barrett, Deputy Secretary of the U.S. Department of Transportation. Five teams of students presented their ideas on sustainable transportation alternatives for the future. These included a magnetic hover bus that can traverse both land and water, a plug-in electric-biodiesel-solar hybrid car, applications of the Stirling engine, a solar-hydropower bus, and an electric car with back-up power from solar panels and an internal windmill. The formal presentations were followed by a moderated question-and-answer session in which student teams questioned each other about their projects and sought the advice of experts about preparation for transportation careers and the critical issues they will face in the future. This publication is an edited summary of the April 2008 event, named in honor of Garrett A. Morgan, a black American inventor honored by Congress for his contributions to transportation and public safety
