Between 2009 and 2013 Cymene Howe and Dominic Boyer conducted fieldwork in Mexico's Isthmus of Tehuantepec to examine the political, social, and ecological dimensions of moving from fossil fuels to ...wind power. Their work manifested itself as a new ethnographic form: the duograph—a combination of two single-authored books that draw on shared fieldsites, archives, and encounters that can be productively read together, yet can also stand alone in their analytic ambitions.In her volume, Ecologics, Howe narrates how an antidote to the Anthropocene became both failure and success. Tracking the development of what would have been Latin America's largest wind park, Howe documents indigenous people's resistance to the project and the political and corporate climate that derailed its renewable energy potential. Using feminist and more-than-human theories, Howe demonstrates how the dynamics of energy and environment cannot be captured without understanding how human aspirations for energy articulate with nonhuman beings, technomaterial objects, and the geophysical forces that are at the heart of wind and power.

Examines four long-term cases of nations shifting to low-carbon energy sources from dependence on fossil fuels, in order to discuss better ways for a nation to make such a transition.
This book addresses the rapidly changing citizen roles in innovation, technology adoption, intermediation, market creation, and legitimacy building for low-carbon solutions. It links research in ...innovation studies, sustainability transitions, and science and technology studies, and builds a new approach for the study of user contributions to innovation and sociotechnical change. Citizen Activities in Energy Transition gives detailed and empirically grounded overall appraisal of citizens’ active technological engagement in the current energy transition, in an era when Internet connectivity has given rise to important new forms of citizen communities and interactions. It elaborates a new way to study users in sociotechnical change through long-term ethnographic and historical research and reports its deployment in a major, decade-long line of investigation on user activities in small-scale renewables, addressing user contributions from the early years to the late proliferation stages of small-scale renewable energy technologies (S-RETs). It offers a much-needed empirical and theoretical understanding of the dynamics of the activities in which users are engaged over the course of sociotechnical change, including innovation, adoption, adjustment, intermediation, community building, digital communities, market creation, and legitimacy creation. This work is a must-read for those seeking to understand the role of users in innovation, energy systems change and the significance of new digital communities in present and future sociotechnical change. Academics, policymakers, and managers are given a new resource to understand the "demand side" of sociotechnical change beyond the patterns of investment, adoption, and social acceptance that have traditionally occupied their attention.
The increasing installation of renewable energy sources (RESs) has led to a growing energy storage demand in the grid. The high cost of batteries and the potential environmental impact of used ...batteries cannot be ignored. Electric spring (ES), as a demand-side management technique, can effectively reduce the energy storage demand by utilizing the allowable power fluctuation range of noncritical load (NCL). Among the existing ESs, the second version ES (ES-2) can compensate both active and reactive power and has received the most attention. However, the existing research articles on ES-2 basically do not consider the power limitation of the NCL, which may result in the NCL voltage exceeding the allowable range and the insufficient reduction of the energy storage demand. To solve this problem, a load voltage angle control strategy for ES-2 is proposed in this article. This control strategy ensures the power fluctuation of NCL within the allowable range by controlling the angle between the critical load voltage and the NCL voltage in real time. Meanwhile, the allowable power fluctuation range of NCL is fully utilized to minimize the battery capacity. Finally, the effectiveness of the proposed control strategy is verified by simulation and experiment.
The implementation of renewable energy sources (RES) in isolated power systems, as is the case of islands, constitutes both a challenge and an opportunity. The intermittency of some RES, namely wind ...and solar, originates problems of grid stability and a mismatch between power demand and supply. The interconnection between isolated power systems can decrease the RES variability and, thereby, minimize the problems associated with their intermittency. In this work, the endogenous resources of the islands of Pico and Faial, in Azores, were characterized and their power systems modelled. A scenario considering the interconnection between the power systems of the two islands is proposed with the objective of increasing the share of RES power in the total power production. The scenario was modelled using EnergyPLAN and the results show that RES penetration can increase 50 percentage points by 2030 in relation to the current situation. The implementation of this scenario requires additional annual costs of about 1.29 M€. Additionally, based on the knowledge gained from this study, measures that may lead, in the long run, to the complete elimination of the overall use of fossil fuels in both islands are presented and discussed.

In recent researches on inverter-based distributed generators, disadvantages of traditional grid-connected current control, such as no grid-forming ability and lack of inertia, have been pointed out. ...As a result, novel control methods like droop control and virtual synchronous generator (VSG) have been proposed. In both methods, droop characteristics are used to control active and reactive power, and the only difference between them is that VSG has virtual inertia with the emulation of swing equation, whereas droop control has no inertia. In this paper, dynamic characteristics of both control methods are studied, in both stand-alone mode and synchronous-generator-connected mode, to understand the differences caused by swing equation. Small-signal models are built to compare transient responses of frequency during a small loading transition, and state-space models are built to analyze oscillation of output active power. Effects of delays in both controls are also studied, and an inertial droop control method is proposed based on the comparison. The results are verified by simulations and experiments. It is suggested that VSG control and proposed inertial droop control inherits the advantages of droop control, and in addition, provides inertia support for the system.
Between 2009 and 2013 Cymene Howe and Dominic Boyer conducted fieldwork in Mexico's Isthmus of Tehuantepec to examine the political, social, and ecological dimensions of moving from fossil fuels to ...wind power. Their work manifested itself as a new ethnographic form: the duograph—a combination of two single-authored books that draw on shared fieldsites, archives, and encounters that can be productively read together, yet can also stand alone in their analytic ambitions.In his volume, Energopolitics, Boyer examines the politics of wind power and how it is shaped by myriad factors, from the legacies of settler colonialism and indigenous resistance to state bureaucracy and corporate investment. Drawing on interviews with activists, campesinos, engineers, bureaucrats, politicians, and bankers, Boyer outlines the fundamental impact of energy and fuel on political power. Boyer also demonstrates how large conceptual frameworks cannot adequately explain the fraught and uniquely complicated conditions on the isthmus, illustrating the need to resist narratives of anthropocenic universalism and to attend to local particularities.
Challenging one-eyed technology-focused accounts of renewables policy, this book provides a ground-breaking, deep-diving and genre-crossing longitudinal study of policy development. The book develops ...a multi-field explanatory approach, capturing inter-relationships between actors often analyzed in isolation. It provides empirically rich and systematically conducted comparative case studies on the political dynamics of the ongoing energy transition in six European countries. While France, Germany, Poland and the United Kingdom opted for ‘technology-specific’ renewables support mixes, Norway and Sweden embarked on ‘technology-neutral’ support mixes. Differences between the two groups result from variations in domestic political and organizational fields, but developments over time in the European environment also spurred variation. These findings challenge more simplistic and static accounts of Europeanization. This volume will be of key interest to scholars and students of energy transitions, comparative climate politics, policy theory, Europeanization, European integration and comparative European politics more broadly, as well practitioners with an interest in renewable energy and climate transition.

This book showcases how small-scale renewable energy technologies such as solar panels, cookstoves, biogas digesters, microhydro units, and wind turbines are helping Asia respond to a daunting set of ...energy governance challenges. Using extensive original research this book offers a compendium of the most interesting renewable energy case studies over the last ten years from one of the most diverse regions in the world. Through an in-depth exploration of case studies in Bangladesh, China, India, Laos, Indonesia, Malaysia, Mongolia, Nepal, Papua New Guinea, and Sri Lanka, the authors highlight the applicability of different approaches and technologies and illuminates how household and commercial innovations occur (or fail to occur) within particular energy governance regimes. It also, uniquely, explores successful case studies alongside failures or "worst practice" examples that are often just as revealing as those that met their targets. Based on these successes and failures, the book presents twelve salient lessons for policymakers and practitioners wishing to expand energy access and raise standards of living in some of the world's poorest communities. It also develops an innovative framework consisting of 42 distinct factors that explain why some energy development interventions accomplish all of their goals while others languish to achieve any.
