The challenges facing participants in competitive electricity markets are staggering: high price volatility introduces significant financial risk into an industry accustomed to guaranteed rates of return, while illiquid forward markets prevent effective hedging strategies from being implemented. Valuation, Hedging and Speculation in Competitive Electricity Markets: A Fundamental Approach, examines the unique properties which separate electricity from other traded commodities, including the lack of economical storage, and the impact of a scarce transmission network. The authors trace the sources of uncertainties in the price of electricity to underlying physical and economic processes, and incorporate these into a bid-based model for electricity spot and forward prices. They also illustrate how insufficient market data can be circumvented by using a combination of price and load data in the marking- to-market process. The model is applied to three classes of problems central to the operation of any electric utility or power marketer; valuing generation assets, formulating dynamic hedging strategies for load serving obligations, and pricing transmission contracts and locational spread options. Emphasis is placed on the difference between trades which can be 'booked out' in the forward markets, and those which must be carried through to delivery. Lately, significant attention has been given to the role of regulators in mitigating excessive price levels in electricity markets. The authors conduct a quantitative analysis of the long-term effects of regulatory intervention through the use of price caps. By modeling the dynamic interplay between the observed price levels and the decision toinvest in new generation assets, it is shown how such short term fixes can lead to long term deficits in the available generation capacity, and ultimately to market failures and blackouts.

This two-volume book offers a broad range of discussions on the immense challenge of climate change, one confronting every country on the planet and forcing them to find a path towards a sustainable future that will not have disastrous consequences in relation to our chances of survival. It also presents a snapshot of the status quo, which reflects all the decisions and measures taken to date. Analyzing the consequences of the steps that will shape our future, the two volumes also reflect on important decisions at a global level that have already been taken. In this first volume on green energy, decarbonization, and forecasting the green transition, respected international scholars analyze various technical aspects of and alternatives to the so-called "green energy transition," as well as measures intended to help reach the ambitious goal of net zero emissions within the next thirty years. Throughout the 13 chapters, the authors forecast future scenarios for the use of alternative energy sources. Additionally, the book discusses questions regarding the suitability of current measures and presents innovative alternatives that have remained largely overlooked. This book is a must-read for scholars, researchers and students, as well as policymakers interested in a better understanding of climate change, present scenarios, and alternative solutions and measures.

Hydrogen has been recognised as a universal, clean fuel which is expected to provide energy to our homes, industry and automobiles in the future. It is considered as one of the most interesting alternat ves to petroleum fuels. A considerable amount of research and development work on product ion, storage and transportation, and utilisation of hydrogen is in pro gress allover the world. In India, several institutions have been working on the various aspects of the hydrogen considering it as an energy vector. A three-day National Workshop on Hydrogen Energy was organised at Indian Institute of Technology (lIT) Delhi to focus attent ion on developments in hydrogen energy at national and international levels and to provide a forum to coordinate contemporary research trends in the country in this field. The presentations made at the Workshop covered the topics which are considered to be of significance to work out the perspective, problems and promises for the future for transition to hydrogen energy. The proceedings of the Workshop are reported in this book, which include the inaugural address, description of the national research and development programme in the field of hydrogen energy, papers presented on production, storage and transportation, and utilisation of hydrogen and the panel report. In the inaugural address, emphasis is laid on the need for a trans ition from the presently used fuels to the newer ones, preferably to those which are renewable and non-polluting such as hydrogen."

This book investigates the latest modeling and control technologies in the context of air-conditioning systems. Firstly, it introduces the state-space method for developing dynamic models of all components in a central air-conditioning system. The models are primarily nonlinear and based on the fundamental principle of energy and mass conservation, and are transformed into state-space form through linearization. The book goes on to describe and discuss the state-space models with the help of graph theory and the structure-matrix theory. Subsequently, virtual sensor calibration and virtual sensing methods (which are very useful for real system control) are illustrated together with a case study. Model-based predictive control and state-space feedback control are applied to air-conditioning systems to yield better local control, while the air-side synergic control scheme and a global optimization strategy based on the decomposition-coordination method are developed so as to achieve energy conservation in the central air-conditioning system. Lastly, control strategies for VAV systems including total air volume control and trim & response static pressure control are investigated in practice.

This book aims to give the reader a short, tractable and as far as possible complete introduction to the young theory of hypoplasticity, which is a new approach to constitutive modelling of granular media in terms of rational continuum mechanics.

This open access book is designed as a continuation of the editor's 2019 book Achieving the Paris Climate Agreement Goals. This volume provides an in-depth analysis of industry sectors globally, and its purpose is to present emission reduction targets in 5-year steps (2025 to 2050) for the main twelve finance sectors per the Global Industry Classification System. This scientific analysis aims to support the United Nations Principles for Responsible Investment initiative to give sustainability guidance for the global finance industry. The industry sector pathways presented here are based on the latest global and regional 100% renewable energy and non-energy greenhouse gas Representative Concentration Pathways in order to keep climate change significantly under +1.5 C and thereby achieve the Paris Climate Agreement goals. The heart of this book is three chapters presenting the results of industry scenario modelling. These chapters cover twelve industry and service sectors as well as transportation and buildings. The specific energy demand and specific emissions are presented based on the emission accounting concept of "Scope 1, Scope 2 and Scope 3" emission pathways. This methodology has been developed to measure the climate and sustainability index for companies, and this research project expands the methodology to apply it to entire industry sectors. The results presented here are the first overall industry assessments under Scope 1, 2 and 3 from 2020 through 2050. The base for the energy pathways is the scenarios scenarios published in the previous volume. The nonenergy GHG emission scenarios, broken down to agriculture & forestry and industry, are detailed and include all major greenhouse gases and aerosols. The final section of the book presents the main conclusions of the industry pathway development work and recommendations for the finance industry and policy makers. Additionally, future qualitative future investment requirements in specific technologies and measures are presented.

To protect the Earth, China has launched its target of peaking carbon dioxide emissions by 2030, and achieving carbon neutrality by 2060 , which greatly encourages the use and development of renewable energy. Supercritical CO2 power cycle is a promising technology and the radial inflow turbine is the most important component of it, whose design and optimisation are considered as great challenges. This book introduces simulation tools and methods for supercritical CO2 radial inflow turbine, including a high fidelity quasi-one-dimensional design procedure, a non-ideal compressible fluid dynamics Riemann solver within open-source CFD software OpenFOAM framework, and a multi-objective Nelder-Mead geometry optimiser. Enhanced one-dimensional loss models are presented for providing a new insight towards the preliminary design of the supercritical CO2 radial inflow turbine. Since the flow phenomena within the blade channels are complex, involving fluid flow, shock wave transmission and boundary layer separation, only employing the ideal gas model is inadequate to predict the performance of the turbine. Thus, a non-ideal compressible fluid dynamics Riemann solver based on OpenFOAM library is developed. This book addresses the issues related to the turbine design and blade optimization and provides leading techniques. Hence, this book is of great value for the readers working on the supercritical CO2 radial inflow turbine and understanding the knowledge of CFD and turbomachinery.

This book explores the role which policy networks and particularly advocacy coalitions play in EU energy policy, and the factors that account for their policy success. It captures the often neglected interaction between public and private actors in EU energy security policy and between opposing advocacy coalitions. The volume's case studies examine coalitions working on two issues central to EU energy policy debates over the last decade: fracking for shale gas and developing the Southern Gas Corridor, a pipeline system linking Europe with the gas region of the Caspian Sea. Although the coalitions studied are focused on impacting EU energy policy, they stretch beyond the EU borders. The book draws on original, rich, and intriguing data, around 90 interviews with energy stakeholders and over six months of fieldwork and participant observation, analysed through an innovative combination of frame analysis and social network analysis.

The theory of thermoelasticity studies the interaction between thermal and mechan ical fields in elastic bodies. This theory is of interest both for the mathematical and technical point of view. Intense interest has been shown recently in this field owing to the great practical importance of dynamical effects in aeronautics, nu clear reactors, and its potential importance in cryogenic applications. This work is concerned mainly with basic problems of the theory of thermoelasticity. Ther moelasticity of polar materials and the theories of thermoelasticity with finite wave speeds are not considered here. The reader interested in these subjects will find a full account in the works of Nowacki [280], Chandrasekharaiah [60] and Ignaczak [195]. Our purpose in this work is to present a systematic treatment of some results established in the theory of thermoelasticity. On the whole, the subject matter is directed towards recent developments. Chapter 1 is concerned mainly with the development of the fundamental equa tions of the theory of thermoelasticity. The kinematics and primitive concepts associated with the basic principles are developed and emphasized only to the ex tent that they are needed in our treatment of the subject. Chapter 2 is devoted to a study of linear thermoelastic deformations for prestressed bodies. We have at tempted to isolate those conceptual and mathematical difficulties which arise over and above those inherent in the problems concerned with unstressed bodies.

This textbook teaches the fundamentals of building energy modeling and analysis using open source example applications built with the US DOE's OpenStudio modeling platform and EnergyPlus simulation engine. Designed by researchers at US National Laboratories to support a new generation of high performance buildings, EnergyPlus and OpenStudio are revolutionizing how building energy modeling is taught in universities and applied by professional architects and engineers around the world. The authors, all researchers at National Renewable Energy Laboratory and members of the OpenStudio software development team, present modeling concepts using open source software that may be generally applied using a variety of software tools commonly used by design professionals. The book also discusses modeling process automation in the context of OpenStudio Measures-small self-contained scripts that can transform energy models and their data-to save time and effort. They illustrate key concepts through a sophisticated example problem that evolves in complexity throughout the book. The text also examines advanced topics including daylighting, parametric analysis, uncertainty analysis, design optimization, and model calibration. Building Energy Modeling with OpenStudio teaches students to become sophisticated modelers rather than simply proficient software users. It supports undergraduate and graduate building energy courses in Architecture, and in Mechanical, Civil, Architectural, and Sustainability Engineering.

Energy efficiency plays and will continue to play an important role in the world to save energy and mitigate greenhouse gas(GHG) emissions. However, little is known on how much additional capital should be invested to ensure using energy efficiently as it should be, and very little is known which sub-areas, technologies, and countries shall achieve maximum greenhouse gasemissions mitigation per dollar of investment in energy efficiency worldwide.

Analyzing completed and slowly moving energy efficiency projectsby the Global Environment Facilityduring 1991-2010, "Closing the Gap: GEF Experiences in Global Energy Efficiency "evaluates impacts of multi-billion-dollar investments in the world energy efficiency. It covers the following areas:

1. Reviewing the world energy efficiency investment and disclosing the global energy efficiency gapand market barriersthat cause the gap;

2. Leveraging private funds with public funds and other resources in energy efficiency investments; using these funds in tangible and intangible asset investments;

3. Investment effectiveness in dollars per metric ton of CO2emissions mitigation in 10 energy efficiency sub-areas;

4. Major barriers causing failure and abandonments in energy efficiency investments;

5. Quantification of direct and indirect CO2emissions mitigations inside and outside a project boundary; and

6. Classification and estimation of CO2emissions mitigations from tangible and intangible asset investments.

"Closing the Gap: GEF Experiences in Global Energy Efficiency "can serve as a handbook for policymakers, project investors and managers, and project implementation practitioners in need of benchmarksin energy efficiency project investments for decision-making. It can also be used by students, researchers and other professionals in universities and research institutions in methodology development for evaluating energy efficiency projectsand programs. "

This book aims to present some advanced control methodologies for power converters. Power electronic converters have become indispensable devices for plenty of industrial applications over the last decades. Composed by controllable power switches, they can be controlled by effective strategies to achieve desirable transient response and steady-state performance, to ensure the stability, reliability and safety of the system. The most popular control strategy of power converters is the linear proportional-integral-derivative series control which is adopted as industry standard. However, when there exist parameter changes, nonlinearities and load disturbances in the system, the performance of the controller will be significantly degraded. To overcome this problem, many advanced control methodologies and techniques have been developed to improve the converter performance. This book presents the research work on some advanced control methodologies for several types of power converters, including three-phase two-level AC/DC power converter, three-phase NPC AC/DC power converter, and DC/DC buck converter. The effectiveness and advantage of the proposed control strategies are verified via simulations and experiments. The content of this book can be divided into two parts. The first part focuses on disturbance observer-based control methods for power converters under investigation. The second part investigates intelligent control methods. These methodologies provide a framework for controller design, observer design, stability and performance analysis for the considered power converter systems.

This research monograph is in some sense a sequel to the author's earlier one (Power System Stability, North Holland, New York 1981) which devoted cons- erable attention to Lyapunov stability theory, construction of Lyapunov fu- tions and vector Lyapunov functions as applied to power systems. This field of research has rapidly grown since 1981 and the more general concept of energy funct ion has found wide spread application in power systems. There have been advances in five distinct areas (i) Developing energy functions for structure preserving models which can incorporate non-linear load models (ii) Energy fu- tions to include detailed model of the generating unit i. e. , the synchronous machine and the excitation system (iii) Reduced order energy functions for large scale power systems, the simplest being the single machine infinite bus system (iv) Characterization of the stability boundary of the post-fault stable eQui- brium point (v) Applications for large power networks as a tool for dynamic security assessment. It was therefore felt appropriate to capture the essential features of these advances and put them in a somewhat cohesive framework. The chapters in the book rough ly fo llow this sequence. It is interesting to note how different research groups come to the same conclusion via different reas- ings.

This book states that sustainable development has become an influential discourse worldwide. Climate change is not only an urgent problem, but it is also a fundamental spiritual question concerning social justice and sustainable peace development as well as solidarity among people of various religious backgrounds and different countries. Thus, this global problem must be faced and recognized for future actions and strategies. However, the politics of fear must be replaced with a culture of peace, hope, and compassion, and this urgent problem must be faced with an optimistic attitude and a certain degree of preparedness. Climate change is evident in many forms, such as, for example, the most obvious-recent weather fluctuations that happen around the world. Floods, droughts, and hurricanes are those visible signs of climate change. Human-caused climate change is projected to greatly impact marine, freshwater, and terrestrial life. Temperatures in Alaska and the Arctic have increased over the last 50 years at a rate more than twice as fast as the global average temperature. Poor people are vulnerable to man-made climate change and respond rapidly to its impacts. Diverse knowledge of and approaches to climate change help understand this growing problem; global average air temperature has increased in the recent past by approximately 1.0 DegreesC (1.8 DegreesF). According to the Climate Science Special Report, the last several years have been record-breaking, and the period of 1901-2016 is the warmest. Greenhouse gas (GHG) emissions are still rising, with damaging effects on the Earth's climate. At the moment, the concentration of CO2 is higher than at any point in time-at least the past 800,000 years. However, carbon dioxide (CO2) is not the only GHG that impacts human-induced climate change.

This book explores the linkages among economic development, energy, and environment. An increase in economic activity is correlated with a higher level of energy consumption, which in turn leads to an increase in environmental pollution. Due to the influence of greenhouse gases, the higher the concentration of pollutants in the atmosphere, the higher the temperature, which ultimately leads to climate change. Under these imminent dangers, the role of economic and energy efficiency policies becomes important for ecological sustainability. The present policies, however, in various instances, have failed to address these issues. Hence, this book embarks not only to suggest modifications to improve the efficacy of the current policies but also to recommend to the policymakers, new and more effective policies for their respective countries. The book is bifurcated into two sections: The Economics and Policy of Sustainable Energy section discusses renewable energy policy responses to observed Impact of climate change using DPSIR Framework; the energy utilization strategies for transportation and commercial activities of Charland Bangladesh; the relationship of market globalization with the Indian energy sector; the socioecological effects of globalization from an energy perspective brought to a local standpoint; the seasonal disaster-induced energy consumption strategies of the char-dwellers of Bangladesh with respect to their domestic chores and agricultural activities; trends in GDP growth and energy usage in India; cross-border trade of electricity; and the events that the oil and gas industry has already faced and possible strategies it can adopt to overcome the recession caused by the COVID-19 pandemic. The Economics and Policy of Environmental Sustainability section analyses topics such as the role of hyper-globalization in spreading the pandemic across countries as threat to human ecology; the current scenario of environmental consequences, and future prospects of plastic pollution; the surface air temperature anomalies over selected countries of Africa; the impaired roles of the female gender in community natural resource exploitation in Ndop; the operational expansion strategies for garnering better output in terms of livelihood and conservation; opportunity for environmental justice and rethinking global community; linking indigenous traditional knowledge and sustainable development goals in the North-Western Himalayas; and recommendations to manage dry forest carbon stock. This book is a rich resource for policymakers, guiding them through untraveled pathways. Moreover, it is an extremely helpful resource for researchers, practitioners, industry professionals as well as students in the fields of energy, environment, and sustainable development with flavour of economics and policy.

The era of the personal computer has, without doubt, permanently altered our life style in a myriad of ways. The "brain" of the personal computer is the microprocessor (together with RAM and ROM) which makes the decisions needed for the computer to perform in the desired manner. The microprocessor continues to evolve as increasingly complex tasks are required. While not sharing the limelight of the microprocessor, the "heart" of the personal computer, namely the power supply, is equally important since without the necessary source of power the microprocessor would be a useless piece of silicon. The power supply of twenty years ago was much different than its modem day equivalent. At the dawn of the personal computer era in the late 1970s, de power was obtained from a simple diode bridge. However, the need for smooth, regulated DC at low voltage required at the same time both a bulky input transformer and a large dc side ftlter. Those computer fans present at the birth of this industry can remember the large boxes housing our Altair, Cromemco and Northstar computers which was made necessary largely because of the huge power supply. It is not well appreciated but certainly true that the huge sucess of the Apple II computer in those days was due, at least in part, to the relatively slim proftle of the machine. This sleek appearance was largely due to the adoption of the then new and unproven switched mode power supply.

This book reconnects energy research with the radical, reflexive, and transformative approaches of Environmental Justice. Global patterns of energy production and use are disrupting the ecosystems that sustain all life, disproportionately affecting marginalized groups. Addressing such injustices, this book examines how energy relates to structural issues of exploitation, racism, colonialism, extractivism, the commodification of work, and the systemic devaluing of diverse 'others.' The result is a new agenda for critical energy research that builds on a growing global movement of environmental justice activism and scholarship. Throughout the book the author reframes 'transitions' as collaborative projects of justice that demand structural change and societal shifts to more equitable and reciprocal ways of living. This book will be an invaluable resource for students, scholars, and practitioners interested in transforming energy systems and working collectively to build just planetary futures.
