Energy is truly the world's most vital commodity. It makes modern societies possible, and the decisions made regarding it have far-reaching... repercussions. Every day stories about the price of oil, the resurgence of nuclear power, or the latest clean energy alternative can be found in mainstream news outlets across the country. Yet despite its high profile, energy remains largely misunderstood. People are confused, intimidated and generally discouraged from learning about energy, partly because the topic is so large and opaque, but also because the resources that do exist fail to provide an overall picture the average reader can understand. Here, in easily accessible language accompanied by simple illustrations of difficult concepts, the authors lay out the basics of energy in a palatable and refreshing way. Readers are treated to a vivid presentation of the basics of energy science, alongside the politics, economics, and social issues that impact its harnessing, distribution, and use. Anyone interested in how energy truly works will find answers in these pages that shed light on the past, present, and future of world energy.

Energy for Sustainability is the first undergraduate textbook on renewable energy and energy efficiency with a unique focus on the community scale.... Written by two of the foremost experts in the field, it is a pedagogically complete treatment of energy sources and uses. It examines the full range of issues—from generating technologies to land use planning—in making the transition to sustainable energy. The book begins by providing a historical perspective on energy use by human civilizations and then covers energy fundamentals and trends; buildings and energy; sustainable electricity; sustainable transportation and land use; and energy policy and planning. Included in these topical areas are in-depth discussions of all of the most promising sources of renewable energy, including solar photovoltaic systems, wind turbines, and biofuels. In addition, the authors offer a thorough presentation of “green” building design, the impact of land use and transportation patterns on energy use, and the policies needed to transform energy markets at the local, state, and national levels. Throughout, the authors first provide the necessary theory and then demonstrate how it can be applied, utilizing cutting-edge practices and technologies, and the most current available data. Since the dawn of the industrial age, the explosive growth in economic productivity has been fueled by oil, coal, and natural gas. World energy use nearly doubled between 1975 and 2005. China’s energy use has been doubling every decade. The implications for the environment are staggering. One way or another, our reliance on fossil fuels will have to end. Energy for Sustainability evaluates the alternatives and helps students understand how, with good planning and policy decisions, renewable energy and efficiency can support world demands at costs we can afford—economically, environmentally, and socially.

Energy: We want it affordable, we want it available in ample quantities and from reliable sources, and we want it to be produced and used in ways that... are safe and environmentally benign. In other words, we want plenty of energy too cheap to meter and with no impact on the environment. Ha! With a refreshing lack of bias, this book dissects all major sources of energy, from oil and coal to renewables like solar and wind power. In an easy, understandable style, energy expert Joseph Dukert explains how each fits into the overall global energy mix that powers everything from automobiles and appliances to assembly lines and space stations.As Dukert details, all energy sources have pluses and minuses. Those who champion any single energy source (or even energy efficiency by itself) as the sole answer to our energy problems are off track, he argues, as are the cynics who condemn one source or another or pooh-pooh the threat of global warming. In short, we need every significant source of energy we have today, while also making greater efforts to improve the efficiency of energy production and energy consumption. Dukert also explores the choices made by individuals, businesses, and society as each group juggles conflicting, interconnected factors: affordability, reliability, adequacy of supply, environmental concerns, and time. In explaining why there's no magic bullet solution to the energy crisis, the author blends simple technical descriptions, economics, and real-world politics. Besides providing a cogent overview of a huge—and hugely important—industry, this short, comprehensive volume helps readers decide for themselves which choices are in their best interest. As Dukert suggests, energy independence is probably not a realistic goal for any country, but the search for a dynamic, practical energy balance can nonetheless result in a wiser national energy policy.

Also called energy scavenging, energy harvesting captures, stores, and uses "clean" energy sources by employing interfaces, storage devices, and other... units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, "green" resources and converting them into electrical energy. Recognizing this need, Energy Harvesting: Solar, Wind, and Ocean Energy Conversion Systems describes various energy harvesting technologies, different topologies, and many types of power electronic interfaces for stand-alone utilization or grid connection of energy harvesting applications. Along with providing all the necessary concepts and theoretical background, the authors develop simulation models throughout the text to build a practical understanding of system analysis and modeling. With a focus on solar energy, the first chapter discusses the I−V characteristics of photovoltaic (PV) systems, PV models and equivalent circuits, sun tracking systems, maximum power point tracking systems, shading effects, and power electronic interfaces for grid-connected and stand-alone PV systems. It also presents sizing criteria for applications and modern solar energy applications, including residential, vehicular, naval, and space applications. The next chapter reviews different types of wind turbines and electrical machines as well as various power electronic interfaces. After explaining the energy generation technologies, optimal operation principles, and possible utilization techniques of ocean tidal energy harvesting, the book explores near- and offshore approaches for harvesting the kinetic and potential energy of ocean waves. It also describes the required absorber, turbine, and generator types, along with the power electronic interfaces for grid connection and commercialized ocean wave energy conversion applications. The final chapter deals with closed, open, and hybrid-cycle ocean thermal energy conversion systems.

Energy in Nature and Society is a systematic and exhaustive analysis of all the major energy sources, storages, flows, and conversions that have shaped... the evolution of the biosphere and civilization. Vaclav Smil uses fundamental unifying metrics (most notably for power density and energy intensity) to provide an integrated framework for analyzing all segments of energetics (the study of energy flows and their transformations). The book explores not only planetary energetics (such as solar radiation and geomorphic processes) and bioenergetics (photosynthesis, for example) but also human energetics (such as metabolism and thermoregulation), tracing them from hunter-gatherer and agricultural societies through modern-day industrial civilization. Included are chapters on heterotrophic conversions, traditional agriculture, preindustrial complexification, fossil fuels, fossil-fueled civilization, the energetics of food, and the implications of energetics for the environment. The book concludes with an examination of general patterns, trends, and socioeconomic considerations of energy use today, looking at correlations between energy and value, energy and the economy, energy and quality of life, and energy futures. Throughout the book, Smil chooses to emphasize the complexities and peculiarities of the real world, and the counterintuitive outcomes of many of its processes, over abstract models. Energy in Nature and Society provides a unique, comprehensive, single-volume analysis and reference source on all important energy matters, from natural to industrial energy flows, from fuels to food, from the Earth's formation to possible energy futures, and can serve as a text for courses in energy studies, global ecology, earth systems science, biology, and chemistry. Vaclav Smil is Distinguished Professor at the University of Manitoba and the author of many books, including Energy at the Crossroads (2003), The Earth's Biosphere: Evolution, Dynamics, and Change (2002), and Energies: An Illustrated Guide to the Biosphere and Civilization (1998), all of which are published by The MIT Press.
