Since the first electrification systems were established in the United States between 1910 and 1930, energy systems governance at the municipal level has included competing visions for how engineering design and energy policy-making should foster particular social outcomes. Using Phoenix as a representative metropolitan area, and the cases of distributed generation and in-home power management devices as examples, this paper explores how the norms and values embedded in energy systems design and planning shape how residents experience change in the energy grid. Through these case studies, the authors argue that such “sociotechnical imaginaries” – collectively formed visions of social life related to science and technology development – are a crucial, yet overlooked, pathway for social science to engage in fostering socially reflexive mechanisms in energy development. To conclude, the authors outline a research program for applying the established methodology of socio-technical integration research (STIR) in order to develop socially reflexive capacities in municipal energy producing, regulating, and planning institutions. Such a program has the ability to produce a deeper intellectual understanding of how energy development occurs, and in doing so generate new pathways for fostering cultural and material changes in the structure of contemporary energy systems. 相似文献

Bangladesh’s energy sector institutionalized neoliberal policies in the early 1990s after a decade long implementation of structural adjustment policies suggested by the World Bank. These policies strengthened the role of foreign private capital and reduced the role of public enterprises. In spite of the country’s success in exploring and developing petroleum resources, the World Bank pushed for policy reforms to reduce the role of state-owned companies. Bangladesh signed several production sharing contracts with multinational energy corporations during 1993–1998. This resulted in the development of a counter-hegemonic social movement, the National Committee. Its activists made the energy sector the most contested national policy domain. Its direct action programs and other mobilization tactics transformed Bangladesh’s public sphere vis-à-vis energy politics. The National Committee caused the government to reverse its decision in some cases, but is far from achieving its main goal: increasing the capability of national institutions to maintain full ownership in natural resource management. Notwithstanding this limitation, the National Committee is a fascinating case of a counter-movement in the Global South contesting neoliberal resource appropriation. 相似文献

To facilitate the use of nuclear energy globally, small modular reactors (SMRs) may represent a viable alternative or complement to large reactor designs. One potential benefit is that SMRs could allow for more proliferation resistant designs, manufacturing arrangements, and fuel‐cycle practices at widespread deployment. However, there is limited work evaluating the proliferation resistance of SMRs, and existing proliferation assessment approaches are not well suited for these novel arrangements. Here, we conduct an expert elicitation of the relative proliferation resistance of scenarios for future nuclear energy deployment driven by Generation III+ light‐water reactors, fast reactors, or SMRs. Specifically, we construct the scenarios to investigate relevant technical and institutional features that are postulated to enhance the proliferation resistance of SMRs. The experts do not consistently judge the scenario with SMRs to have greater overall proliferation resistance than scenarios that rely on conventional nuclear energy generation options. Further, the experts disagreed on whether incorporating a long‐lifetime sealed core into an SMR design would strengthen or weaken proliferation resistance. However, regardless of the type of reactor, the experts judged that proliferation resistance would be enhanced by improving international safeguards and operating several multinational fuel‐cycle facilities rather than supporting many more national facilities. 相似文献

It is widely accepted that some financial data exhibit long memory or long dependence, and that the observed data usually possess noise. In the continuous time situation, the factional Brownian motion BH and its extension are an important class of models to characterize the long memory or short memory of data, and Hurst parameter H is an index to describe the degree of dependence. In this article, we estimate the Hurst parameter of a discretely sampled fractional integral process corrupted by noise. We use the preaverage method to diminish the impact of noise, employ the filter method to exclude the strong dependence, and obtain the smoothed data, and estimate the Hurst parameter by the smoothed data. The asymptotic properties such as consistency and asymptotic normality of the estimator are established. Simulations for evaluating the performance of the estimator are conducted. Supplementary materials for this article are available online. 相似文献

动力电池作为储能最佳的载体之一,是否具备商业价值成为影响储能产业发展的重要因素?在对国内外储能产业发展现状分析的基础上,应用系统动力学理论从发电侧、电网侧和用户侧以及辅助服务等方面对影响商业价值的成本和收益要素进行深入分析。进一步引入碳排放政策下的环境收入等指标,系统梳理各成本/收入指标间的相互关系,构建梯次利用动力电池储能的系统动力学模型。利用VENSIM软件对中国首个"金太阳项目"——"张北风光储输示范项目"的动力电池梯次利用储能的商业价值模型进行仿真模拟。研究表明:梯次利用动力电池储能具有一定的经济性,其商业价值的提高可以从电池成本、政府补贴以及峰谷价差等多角度来思考。未来随着电池成本下降、额定容量增加、峰谷电价差、国家补贴等因素的变化,中国储能产业中动力电池梯次利用的商业价值将会更加显著。 相似文献
