Exergetic Aspects Of Renewable Energy Systems

Energy is essential to all human activities as well as critical to social and economic development. Sustainable energy planning encompassing the concept of smart cities has a high potential to significantly contribute to climate change mitigation. For improved energy efficiency, it is essential to find low carbon solutions for the urban environment. The integration and management of energy supply with predominant exploitation of local resources is examined through the fundamental concept of exergy. This book can assist in decision making, with regard to sustainable energy design both at a national and local level.

Introduction to Energy Systems An in-depth introduction to applications and analysis of energy systems, covering both renewable and traditional types of energy systems In Introduction to Energy Systems, the content is uniquely designed to cover comprehensive descriptions and assessments of all the key types of energy sources, including fossil fuels-based, nuclear, and renewable energy systems, with a special focus on their design, analysis and assessment, technical and operational aspects, and applications. As a comprehensive resource, the work also introduces many topics not typically covered in other energy system textbooks, such as system design and assessment through exergy, environmental impact assessment of energy systems, and life cycle assessment. From a theory standpoint, the book provides context on the importance of energy and the issues related to energy we face in our world today, with close attention paid to key environmental and sustainability issues. Furthermore, the book includes illustrative examples and problems, and case studies. To aid in seamless reader comprehension, helpful questions and problems are included at the end of each chapter. Sample topics covered in Introduction to Energy Systems include: Fundamental concepts and thermodynamic principles, traditional and innovative systems, and detailed applications in renewable energy systems, including solar, wind, geothermal, biomass, hydro, and marine energies Different types of fuels used in energy systems today, discussions of their combustion characteristics with a clear analysis of each one, and analyses and assessments through energy and exergy approaches Industrial ecology and life cycle assessment, with the intention of clearly assessing the environmental impacts of energy systems How to write balance equations for mass, energy, entropy and exergy, calculate the required capacities, and find the energy and exergy efficiencies and/or energetic and exegetics coefficient of performance values Introduction to Energy Systems serves as a valuable learning resource for both undergraduate and graduate students studying courses, such as Introduction to Energy Systems, Energy System Design, Renewable Energy, Energy & Sustainability, and Fundamentals of Renewable Energy.

Exergy has been defined as the maximum work that is useful, extracted from any process toward its equilibrium. Hence, it has a very strong connection with the second law of thermodynamics. In energy harvesting and management systems, the concept of exergy is very important because it represents the efficiency of the system. Exergy can be used as a tool to measure resource efficiency, as well as whole system sustainability. In addition, it can also be used to analyze and clarify the performance of each process; hence, methods of improvement can be determined.This book is the result of a very careful selection of chapters and contributors in the related field. The book is divided into three main sections according to the approaches and purpose of each proposed chapter. The first section is an introduction to the book. The second section, "Advanced energy conversions", describes several advanced technologies that are considered to have great potential in energy conversion and harvesting, and comprises three chapters focusing on photovoltaic/thermal systems with nanofluid, power-to-gas energy storage systems coupled with a combined cycle employing chemical looping combustion technology, and electromagnetic-based power generation. The third section focuses on the idea of "innovative energy management systems" toward high-quality energy systems. In this section, two different chapters describe the introduction of electric vehicles for demand-side energy management and the utilization of supercapacitors for very responsive energy storage in low-power modules. It is expected that this book will provide and enrich the state of the art in advanced energy systems, including energy conversion and management. All the chapters cover a broad range of disciplines, which are correlated in terms of the efforts toward efficient energy systems. In addition, the correlation between energy and exergy, and their understanding, are believed to be very important to improve energy efficiency and guarantee better energy quality.
