A geologist specializing in geothermal energy, Glassley explains where the energy comes from, how to find it, how to access it, the kinds of applications that have been successful in the past, and what could be done to improve its use in the future. He also considers its dangers and limitations and economic and social issues it raises. His topics include Earth as a heat engine, the geology and geochemistry of exploring for geothermal systems, resource assessments, drilling, geothermal heat pumps for low-temperature geothermal resources, and environmental considerations in using geothermal resources. Annotation ©2015 Ringgold, Inc., Portland, OR (protoview.com) An In-Depth Introduction to Geothermal EnergyAddressing significant changes in the energy markets since the first edition, Geothermal Energy: Renewable Energy and the Environment, Second Edition expounds on the geothermal industry, exploring the expansion, growth, and development of geothermal systems. This text covers every area of geothermal energy, including environmental and economic issues, and technological advancements. Considers the Vast Technological Achievements within the Geothermal IndustryFactoring in new concepts for distributed generation, hybrid technologies, and the development of Enhanced Geothermal Systems (EGS), the book incorporates real-world examples designed to illustrate the key aspects of chapter topics. It provides case studies in nearly every chapter, and includes examples from the U.S., Iceland, France, and Japan.Contains comprehensive, quantitative, and rigorous treatment of the geology, geochemistry, and geophysics of geothermal resources, and how they impact exploration, resource assessment, and operationsProvides a state-of-the-art description of current Enhanced Geothermal Systems (EGS)Presents an objective description of the most recent economic comparisons including all energy resourcesCovers environmental issues of energy use and quantitative descriptions of the relative impacts of all renewable and non-renewable energy resourcesDescribes geothermal resources from a global perspective, including direct use and geothermal heat pump applications, as well as power productionGeothermal Energy: Renewable Energy and the Environment, Second Edition can be used for undergraduate coursework; as a reference for designers, planners, engineers, and architects; and as a source of background material for policymakers, investors, and regulators.

Recenzijos

"... a well-written all-inclusive updated version of the first edition presents advances in understanding the economics and valuation of resources, particularly the expanded attention to life cycle analysis on energy returned on energy invested approaches." Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2015

"This is a very well written book and is very useful for both scientists as well as technologists as the ready reference for geothermal energy. It deals with every possible latest aspect with basic concepts along with the mathematical description. It will certainly be very handy for the planner as well as students who like to tap the potential of alternate energy resource." Professor Sandeep Singh, IIT Roorkee, India

"Great introductory treatment of all aspects of geothermal energy from sources and occurrences, to exploration and utilization, to economic and environmental aspects, and to the future possibilities." Andrew Chiasson, Oregon Institute of Technology, Klamath Falls, USA

"This book provides a thorough, solid grounding in the basic physical science needed to understand geothermal energy. This is not always the case in writings on renewable energy! The reader of Glassleys book will come away with a clear understanding of basic thermodynamics, geophysics, and geochemistry at a fundamental level. That leads to a deeper appreciation for the technological needs and challenges of geothermal energy systems. The book is quantitative throughoutan essential feature if one is to grasp the true potential of any renewable energy resource." Richard Wolfson, Professor of Physics & Environmental Studies, Middlebury College, Vermont, USA

"provides an excellent general discussion of the major elements in this new aspect of geothermal energy development such as the "magnitude" and "characteristics" of these systems for the non-geoscientist as well as undergraduate and graduate science students." Joe Iovenitti, Consulting Geoscientist, USA

"This textbook will help educate the next generation of geothermal practitioners who will implement the solutions needed to grow geothermal energy so that it becomes a key part of the future renewable energy mix."
