The direct conversion of daylight into electricity by photovoltaic solar cells is one of the most promising of the renewable energy options. The importance of the technology is reflected in the growth in the field. What was largely technology for space programmes in 1976 produced 28.6 MW of terrestrial modules in 1987. The popularity of the technology can partly be explained by its versatility. Arrays of any size and voltage can be constructed from standard modules, with the conversion efficiency being practically independent from output. Photovoltaics are also well suited to on-site generation of power in remote areas. This book is intended primarily to give students, engineers and scientists entering the photovoltaics field an overview of all aspects of the subject, with pointers to further reading. However, by using simple language and avoiding jargon, an effort has been made to make the work useful and interesting to the general public.

As mankind searches for energy alternatives with minimal environmental consequences and acceptable cost, it is necessary to identify valid areas of endeavor that can activate favorable energy sources and technological developments. Toward that end, The Dynamics of Energy: Supply, Conversion, and Utilization develops competence in energy matters on three levels: basic concepts, essential computations, and dynamic modeling. The book reviews the laws of thermodynamics and rate relationships between flows and gradients as a foundation for subsequent topics. Using dynamic analysis, it examines the potential of current energy sources to serve the needs of a growing world economy. The text also describes key fossil conversion, renewable conversion, and utilization technologies. It presents a technique to assess efficiencies from ground (or harvest) to end use, explores the effects of energy use on the environment, and offers an introduction to dynamic modeling. The book concludes with a description of energy technologies that, if suitably employed, could configure a sustainable energy future. Studying the dynamics of thermal systems is conducive to ascertaining what technologies could indeed make a difference for a desirable energy future. Suitable response time to demand and acceptable fuel lifetimes are necessary conditions for energy systems to compete in the marketplace. The planning effort that should lead the energy endeavor requires projection of the time span of pollution effects. Harnessing the flexibility and speed of VisSim(TM) for dynamic modeling, this book provides the tools to model most thermal systems with moderate complexity. It also evaluates energy supplies, conversion, and end use.
'The Jevons Paradox', which was first expressed in 1865 by William Stanley Jevons in relation to use of coal, states that an increase in efficiency in using a resource leads to increased use of that resource rather than to a reduction. This has subsequently been proved to apply not just to fossil fuels, but other resource use scenarios. For example, doubling the efficiency of food production per hectare over the last 50 years (due to the Green Revolution) did not solve the problem of hunger. The increase in efficiency increased production and worsened hunger because of the resulting increase in population. The implications of this in today's world are substantial. Many scientists and policymakers argue that future technological innovations will reduce consumption of resources; the Jevons Paradox explains why this may be a false hope. This is the first book to provide a historical overview of the Jevons Paradox, provide evidence for its existence and apply it to complex systems. Written and edited by world experts in the fields of economics, ecological economics, technology and the environment, it explains the myth of efficiency and explores its implications for resource usage (particularly oil). It is a must-read for policymakers, natural resource managers, academics and students concerned with the effects of efficiency on resource use.
A unique electrical engineering approach to alternative sources of energy Unlike other books that deal with alternative sources of energy from a mechanical point of view, Integration of Alternative Sources of Energy takes an electrical engineering perspective. Moreover, the authors examine the full spectrum of alternative and renewable energy with the goal of developing viable methods of integrating energy sources and storage efficiently. Readers become thoroughly conversant with the principles, possibilities, and limits of alternative and renewable energy. The book begins with a general introduction and then reviews principles of thermodynamics. Next, the authors explore both common and up-and-coming alternative energy sources, including hydro, wind, solar, photovoltaic, thermosolar, fuel cells, and biomass. Following that are discussions of microturbines and induction generators, as well as a special chapter dedicated to energy storage systems. After setting forth the fundamentals, the authors focus on how to integrate the various energy sources for electrical power production. Discussions related to system operation, maintenance, and management, as well as standards for interconnection, are also set forth. Throughout the book, diagrams are provided to demonstrate the electrical operation of all the systems that are presented. In addition, extensive use of examples helps readers better grasp how integration of alternative energy sources can be accomplished. The final chapter gives readers the opportunity to learn about the HOMER Micropower Optimization Model. This computer model, developed by the National Renewable Energy Laboratory (NREL), assists in the design of micropower systems and facilitates comparisons of power generation techniques. Readers can download the software from the NREL Web site. This book is a must-read for engineers, consultants, regulators, and environmentalists involved in energy production and delivery, helping them evaluate alternative energy sources and integrate them into an efficient energy delivery system. It is also a superior textbook for upper-level undergraduates and graduate students.
$26.95 US $33.00 CAN From the acclaimed author of The Pencil and To Engineer is Human, The Essential Engineer is an eye-opening exploration of the ways in which science and engineering must work together to address our world's most pressing issues, from dealing with climate change and the prevention of natural disasters to the development of efficient automobiles and the search for renewable energy sources. While the scientist may identify problems, it falls to the engineer to solve them. It is this inherent practicality of engineering, which takes into account structural, economic, environmental, and other factors that science often does not consider, that makes engineering vital to answering our most urgent concerns. Henry Petroski takes us inside the research, development, and debates around the most critical challenges of our time, exploring the feasibility of biofuels, the progress of battery-operated cars, and the question of nuclear power. He gives us an in-depth investigation of the various options for renewable energy--among them solar, wind, tidal, and ethanol--explaining the benefits and risks of each. Will windmills soon populate our landscape the way they did in previous centuries? Will synthetic trees,, said to be more efficient at absorbing harmful CO2 than real trees, soon dot our prairies? Will we construct a "sunshade" in outer space to protect ourselves from dangerous rays? In many cases, the technology already exists, and what's needed is not so much invention as engineering. Just as the great achievements of centuries past--the steamship, the airplane, the moon landing--once seemed beyond reach, the solutions of the 21st century's problems await only a similar coordination of science and engineering. Eloquently reasoned and written, The Essential Engineer identifies and illuminates these problems--and above all sets out a course for putting ideas into action.

Given the manifold deficits of financial sectors in developing and transition countries, one might be tempted to believe that embarking on "green" finance is not a priority for financial systems development. However, environmental finance can and should serve as an interface to other sub-sectors of financial sector promotion such as microfinance, housing finance or agricultural finance. For example, existing clients of financial institutions include small and medium-sized enterprises and households, and these are often suffering from high energy prices or have no access to sustainable energy supply. At the same time, these clients are vulnerable to extreme weather events, and often hit hardest by the impact of climate change. There are many other examples which show that the financial sector has an enormous potential to support "green" investments. This book provides a blend of well-founded professional and scientific perspectives on the potential of Energy Efficiency and Renewable Energy (EERE) finance in developing and transition countries.

Advanced biotechnologies enable breeders to produce a whole generation of new crops for specialist needs ("designer crops"), including raw materials for the energy, chemical and pharmaceutical industries. This book provides concerns useful to promote an increase of the productivity of crops by using functional genomics (to understand the regulation of plant metabolism at molecular, cellular and whole plants), and the improvement of photosynthetic efficiency (to design new plants with enhanced raw materials percent and recovery). Fundamental thematics have been addressed: metabolic engineering, plant breeding tools, renewable biomass for energy generation, fibres and composites, biopharmaceuticals. The gained know how is relevant to identify bottlenecks in the major production chains and to propose actions for moving these issues forward: in particular to; i) produce new compounds by expressing foreign heterologous genes; ii) modify pathways to influence quality and/or yield of existing indigenous molecules; iii) bioprocess plant or organic waste stream into value-added products. The chapters of this book have been written by experts from all around the world. Consequently, this book is expected to be of great interest to scientists, researchers, farmers, processors and retailers, but also to students, technocrats and planners interested in the progress made with the development of new industrial crops.

Increasing energy efficiency and the use of renewable energy are the most important actions that can be taken to combat climate changes. As a result, the growth of clean energy will likely be one of the major economic engines of the coming decade.
This title includes a number of Open Access chapters. The world's interest in reducing petroleum use has led to the rapid development of the biofuel industry over the past decade or so. However, there is increasing concern over how current food-based biofuels affect both food security and the environment. Second-generation biofuels, however, use widely available sources such as non-food lignocellulosic-based biomass and fats, oils, and greases. They make practical consideration of how land use can simultaneously support both the world's food needs and some of its energy needs. This volume consolidates some of the most recent investigations into these issues. The chapters focus on these categories of research: The problems currently connected with biofuels relating to land use and the environment Investigations into the potential for land use to be managed more effectively and sustainably Research that focuses on new and developing options for second-generation biofuels This volume is recommended for all biofuel researchers, from the PhD student to the experienced scientist. It also offers an essential foundation to anyone interested in how biofuels relate to the future of our world.
