The Physics of Stocks and Flows of Energy Systems


Book Description

Using a system dynamics approach, this book illustrates the physics of fundamental accumulation processes (stocks and flows) across the demand and supply sectors of energy systems. Examples of system dynamics simulation models are presented where these accumulation processes are driving the behavior of the system. Based on these modeling efforts, two cases (the socio-economic and environmental implications of the energy policy of Pakistan and the dynamics of green power in Ontario, Canada) are analyzed and discussed. By studying the dynamics of the fundamental structures of an energy system, the reader gains an enhanced understanding of the stocks and flows of complex systems as well as their role in energy policy. This book is of use to managers and practitioners, teachers, researchers, and students of design and assessment of policy making for complex, dynamic energy systems.




Changing Stocks, Flows and Behaviors in Industrial Ecosystems


Book Description

This book marks an important contribution by Matthias Ruth and Brynhildur Davidsdottir to the developing literature that seeks to integrate our understanding of physical and environmental systems, the built human environment, economics, and complexity. It is a valuable resource for anyone interested in industrial ecology, material flow assessment, and the state of the world generally. Braden R. Allenby, Arizona State University, US This volume offers the state-of-the-art in dynamic modeling of the functioning of firms in industrial ecosystems. The systematic connection between insights from engineering, ecological, behavioral and organization theories makes the insights policy-relevant. The authors combine an impressive knowledge of innovative concepts and modeling techniques with data on real-world industrial ecosystems. Jeroen van den Bergh, Free University, Amsterdam, The Netherlands Industrial ecology provides a consistent material and energetic description of human production and consumption processes in the larger context of environmental and socioeconomic change. The contributors to this book offer methodologies for such descriptions, focusing on the dynamics associated with stocks of materials and capital, flows of raw materials, intermediate products, desired outputs and wastes, as well as the associated changes in behaviors of producers, consumers and institutions. The book begins by presenting analogies and analytical concepts pertinent to understanding the dynamics of industrial ecosystems, and offers a reflection on the use of those analogies and concepts, their limitations and potential extensions. Part II focuses on stocks and flows dynamics at the firm and industry level. Part III turns to the use of agent-based modeling and organization behavior theory to better understand and represent the dynamics within firms and the larger institutional environment within which they choose to use materials, energy and technology. Connections are made throughout between those dynamics and the associated changes in environmental quality. The concluding chapter addresses how to change a firm s environmental performance from within. Researchers and students in the fields of industrial ecology; resource and environmental economics; ecological economics; environmental, energy, and climate change policy; environmental engineering; and energy economics will find this comprehensive volume highly informative.




Formulating a Pilot Model for Energy in Relation to the National Economy


Book Description

This dynamic linear-programming model, on a pilot scale is an attempt to describe in physical terms many of the technological interactions within and across the sectors of the economy, including a detailed energy sector. The general objective of the model is to determine, in the face of changing energy picture, what the country can achieve in physical terms over the long term, say 30 years. Preliminary work on the pilot model indicates that it can be completed within six months and that several useful scenarios can be run during the ensuing six months.

Energy Policy Modeling in the 21st Century


Book Description

The roles and applications of various modeling approaches, aimed at improving the usefulness of energy policy models in public decision making, are covered by this book. The development, validation, and applications of system dynamics and agent-based models in service of energy policy design and assessment in the 21st century is a key focus. A number of modeling approaches and models for energy policy, with a particular focus on low-carbon economic development of regions and states are covered. Chapters on system dynamics methodology, model-based theory, fuzzy system dynamics frame-work, and optimization modeling approach are presented, along with several chapters on future research opportunities for the energy policy modeling community. The use of model-based analysis and scenarios in energy policy design and assessment has seen phenomenal growth during the past several decades. In recent years, renewed concerns about climate change and energy security have posed unique modeling challenges. By utilizing the validation techniques and procedures which are effectively demonstrated in these contributions, researchers and practitioners in energy systems domain can increase the appeal and acceptance of their policy models.




SYSTEM DYNAMICS - Volume II


Book Description

System Dynamics is a component of Encyclopedia of Technology, Information, and Systems Management Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The world is facing a wide range of increasingly complex, dynamic problems in the public and private arenas alike. System dynamics discipline is an attempt to address such dynamic, long-term policy problems. Applications cover a very wide spectrum, including national economic problems, supply chains, project management, educational problems, energy systems, sustainable development, politics, psychology, medical sciences, health care, and many other areas. This theme provides a comprehensive overview of system dynamics methodology, including its conceptual / philosophical framework, as well as the technical aspects of modeling and analysis. System dynamics can address the fundamental structural causes of the long-term dynamic contemporary socio-economic problems. Its "systems" perspective challenges the barriers that separate disciplines. The interdisciplinary and systemic approach of system dynamics could be critical in dealing with the increasingly complex problems of our modern world in this new century. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.




Economics of Industrial Ecology


Book Description

Studies that integrate scientific, technological, and economic dimensions of industrial ecology and material flows. The use of economic modeling techniques in industrial ecology research provides distinct advantages over the customary approach, which focuses on the physical description of material flows. The thirteen chapters of Economics of Industrial Ecology integrate the natural science and technological dimensions of industrial ecology with a rigorous economic approach and by doing so contribute to the advancement of this emerging field. Using a variety of modeling techniques (including econometric, partial and general equilibrium, and input-output models) and applying them to a wide range of materials, economic sectors, and countries, these studies analyze the driving forces behind material flows and structural changes in order to offer guidance for economically and socially feasible policy solutions. After a survey of concepts and relevant research that provides a useful background for the chapters that follow, the book presents historical analyses of structural change from statistical and decomposition approaches; a range of models that predict structural change on the national and regional scale under different policy scenarios; two models that can be used to analyze waste management and recycling operations; and, adopting the perspective of local scale, an analysis of the dynamics of eco-industrial parks in Denmark and the Netherlands. The book concludes with a discussion of the policy implications of an economic approach to industrial ecology.




Collaborative Modeling And Decision-making For Complex Energy Systems
