Providing electricity to the unlit and unstable parts of the globe is crucial to jump-starting development, improving the environment, and stabilizing fragile states that ferment many of today's security threats. Let There Be Light shows the failures of centralized electricity to meet these challenges - and describes how distributed, renewable energy such as solar and wind power can work. But, Kleinfeld and Sloan argue, it is not enough to harness the power of the elements. To scale, distributed energy must harness the power of the market. Taking on the major challenges that have impeded distributed energy's success, this book describes the roles development donors, social entrepreneurs, venture capitalists, the military, and the business world can play to make lighting the developing world a reality.

Perfect for independent math practice, this primary calculator set lets your students start with basic math operations and work their way up to percents and square roots. Dual-power operation runs on both solar energy and battery power for reliable use in any setting. Calculators also include auto shutoff, three-key memory and more. Four-function calculators with an eight-digit display are designed for children ages 3 and up.

Heat Exchanger Network Synthesis provides engineers, designers, and industrial practitioners with a how-to manual for understanding the methodology for conserving energy through process integration.

- An original textbook that combines several disciplines that together allow understanding and analyzing of conflict, negotiation and cooperation in transboundary water- The book contains a CD with a computer program that allows users to practice various concepts of cooperation, demonstrating them via quantitative examples and outcomes- A balanced set of conceptual approaches and case studies from all over the world- Each chapter includes sections on chapter objectives; glossary of main terminology; summary; practice questions; and list of recommended readings.

Given the potential disruption of climate change, understanding energy issues and technologies is more important than ever if societies are to make informed choices on policy. Now in its third edition, Introduction to Energy explores the crucial issues connected to modern energy technology and its uses. Fully updated to respond to the substantial developments in the energy sector, the book expands on the relationships of energy use and climate change; of energy availability and the alleviation of world poverty; and of energy consumption and the sustainability of the lifestyles of people in the industrialized world. Directed at a broad readership, it assumes no prior technical expertise and avoids complex mathematical formulations, continuing to provide a standard for introductory energy courses. It is also a useful supplementary text for programs in public policy, business law and resource economics.

Written with the installing electrician in mind, THE GUIDE TO PHOTOVOLTAIC SYSTEM INSTALLATION provides readers with a simple, straightforward approach to understanding photovoltaic system installation in both residential and light commercial buildings. Filled with illustrations, examples, and multiple opportunities for practice, this comprehensive book includes the most up-to-date information on photovoltaic installation available on the market today. In addition, coverage of topics such as the National Electrical Code© requirements for a photovoltaic system installation ensures that readers will be well prepared for the North American Board of Certified Energy Practitioners' (NABCEP) entry level photovoltaic installer certification exam.

tions is not possible without first putting the problem into a wider con­ text. Consequently, before proceeding with detailed critical topical cov­ erage of individual biomass energy sources, uses, and effects, I will extend this preface with a few pages of rather personal reflections (I will use the same device in closing the book: after providing concise topical summaries in Chapter 8, I will conclude with some essayistic musings on renewable energetics, plants, people, and a scientist's responsibility). Interest in biomass energies is just a part of a broader global trend toward renewable energetics, a trend which has evolved speedily after the crude oil price escalation started in 1973. Yet one must be reminded that for the rich countries fossil fuels are, and for a long period shall remain, the foundation of an affluent civilization, while throughout the poor world the reliance of most people on biomass energies for everyday subsistence has brought many damaging environmental and social ef­ fects; that the reality of sharp price rises for crude oil (actually not so sharp once adjusted for inflation) should not be misconstrued as an "energy crisis"; that the rise of renew abies and the claims made on their behalf by countless enthusiasts look so much better on paper than in reality; and that the potential of biomass energies, an essential ingre­ dient of renewable scenarios, has been judged more with proselytizing zeal than with critical detachment.

The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.
