This volume provides an overview of the political economy of coal in diverse country contexts.Coal is the largest source of greenhouse gas emissions globally, accounting for about 40 percent of energy-related CO2 emissions. Continued construction of coal-fired power plants could make the climate targets of the Paris Agreement infeasible to achieve. In spite of sharply declining costs for renewable energy sources, many countries still heavily rely on coal to meet their energy demand. The predominance of coal can only be adequately understood in light of the political factors that determine energy policy formulation. To this end, this edited volume assembles a wide variety of case studies exploring the political economy of coal for across the globe. These includes industrial and developing nations, coal importers and exporters as well as countries that are either substantial coal users, are just beginning to ramp up their capacities, or have already initiated a coal phase-out. Importantly, all case studies are structured along a unifying framework that focuses on the central actors driving energy policy formulation, their main objectives as well as the context that determines to what extent they can influence policy making. This large set of comparable studies will permit drawing conclusions regarding key similarities as well as differences driving coal use in different countries.This book will be of great interest to students and scholars of energy, climate change, resource management, and sustainable development. It will also appeal to practitioners and policymakers involved in sustainable development.The Open Access version of this book, available at www.taylorfrancis.com, has been made available under a Creative Commons Attribution- Non Commercial- No Derivatives 4.0 license.

High penetration of renewable energy sources (RESs) imposes several techno-economic challenges to distribution system operators (DSOs) due to their variability in power generation and, hence, increases the need for additional operational flexibility. Operational flexibility aims at securely covering the possible variations at the minimum cost using emerging flexible alternatives or designing novel local market mechanisms to incentivize flexibility providers. In such a situation, the DSOs can use the potential of flexible options such as energy storages (ESs), demand response (DR), plug-in electric vehicles (PEVs), or on-site fast run generators. However, each of the mentioned flexible resources has its own specific characteristics and requirements that should be taken into account, and this raises the complexity. Optimal network reconfiguration schemes are the other solution for increasing power system flexibility at the distribution level. There is a great research gap related to renewable-based distribution network planning from a flexibility point of view. Therefore, this book aims to discuss the additional flexibility needs introduced by RESs and describe general approaches to analyze the need for and provision of additional flexibility in future distribution networks at both the planning and operational time frames. This book successfully suggests new solutions and techniques to increase the flexibility in distribution systems. It also highlights the needs for moving towards smart distribution grids in order to enhance the flexibility in modern and future power systems.

Transportation electrification, particularly using electric vehicles (EV), has been widely suggested to mitigate global warming and energy security issues due to their economic and environmental benefits. Environmentalists are advertising EV use, and governments are implementing financial incentives to expedite the transition from conventional vehicles to electric ones to achieve energy security and climate change mitigation goals. At the same time, EVs are becoming more affordable as their battery prices decrease. It has been predicted that EV sales will soon surpass gasoline and diesel vehicle sales. Therefore, EVs will be one of the significant electricity customers in the future. This fact hints that the uncontrolled charging and discharging of large numbers of EVs can put power systems at risk. Hence, optimal planning and operation of EVs is not only necessary but beneficial. This collection covers recent research advancements in the planning and operation of EVs in smart grids. Aglobal group of researchers and scholars present innovative approaches while covering the theoretical and experimental aspects.
