Nonimaging optics is a subdiscipline of optics whose development over the last 35-40 years was led by scientists from the University of Chicago and other cooperating individuals and institutions. The approach provides a formalism that allows the design of optical devices that approach the maximum physically attainable geometric concentration for a given set of optical tolerances. This means that it has the potential to revolutionize the design of solar concentrators. In this monograph, the basic practical applications of the techniques of nonimaging optics to solar energy collection and concentration are developed and explained. The formalism for designing a wide variety of concentrator types, such as the compound parabolic concentrator and its many embodiments and variations, is presented. Both advantages and limitations of the approach are reviewed. Practical and economic aspects of concentrator design for both thermal and photovoltaic applications are discussed as well. The whole range of concentrator applications from simple low-concentration nontracking designs to ultrahigh-concentration multistage configurations is covered.

This is the only ac cover that keeps the inside and outside completely unclogged from leaves and debris summer/all year (even when air conditioner is in use)....... Can be used for heater/pool pumps as well.. When leaves or debris decay they give off acidic gases that eat at your a/c unit's copper tubing, by making small holes that allow freon to escape, causing your compressor to fail........ Our covers extend the life of your unit by preventing rusting of parts by moisture being trapped inside . Trapped moisture is the main cause of failure to electronics, electrical connections, switches and metal parts. ........

Using appealing cartoons with a cast of lively and curious kids, experts Malcolm Wells and Tilly Spetgang demonstrate how solar power works in a wonderfully clear and understandable way. The fun lesson unfolds in a classroom where students explore solar energy and today's technology: active systems, passive solar, and the conversion of sunlight into electricity. In addition to learning why the sun is superior to nonrenewable fuels, young environmentalists will discover the many cool things you can do with this clean and natural energy. And it's all spiced with irreverent humor that makes the complex subject not only easy to grasp, but delightful. Plus, for their adult friends and relatives, it is a simple and clear lesson on the need for solar power in this environmentally challenged world we live in.

Hiroshi Komiyama's "Vision 2050" is a plan for paving a road to global sustainability. It lays out a path to a sustainable future for humanity that could realistically be achieved by 2050 through the application of science and technology. A prominent Japanese academic and leader in global sustainability, Komiyama draws upon realistic assumptions and solid scientific concepts to create a vision that makes the living standards enjoyed by developed countries today possible for all people by 2050. "Vision 2050" is built upon three fundamental principles a " increased energy efficiency, recycling, and development of renewable energy sources a " and the book argues for the technological potential of all three. Specifically, Komiyama envisions a three-fold increase in overall energy efficiency and a doubling of renewable energy resources by 2050. "Vision 2050: Roadmap for a Sustainable Earth" is written to address the concerned citizen as well as to inspire an exchange of ideas among experts, policy makers, industrial leaders, and the general public.
Provides a systems approach to sustainable green energy production and contains analytical tools to aid in the design of renewable microgrids This book discusses the fundamental concepts of power grid integration on microgrids of green energy sources. In each chapter, the author presents a key engineering problem, and then formulates a mathematical model of the problem followed by a simulation testbed in MATLAB, highlighting solution steps. The book builds its foundation on design of distributed generating system, and design of PV generating plants by introducing design- efficient smart residential PV microgrids. These include energy monitoring systems, smart devices, building load estimation, load classification, and real-time pricing. The book presents basic concepts of phasor systems, three-phase systems, transformers, loads, DC/DC converters, DC/AC inverters, and AC/DC rectifiers, which are all integrated into the design of microgrids for renewable energy as part of bulk interconnected power grids. Other topics of discussion include the Newton formulation of power flow, the Newton—Raphson solution of a power flow problem, the fast decoupled solution for power flow studies, and short circuit calculations. Focuses on the utilization of DC/AC inverters as a three-terminal element of power systems for the integration of renewable energy sources Presents basic concepts of phasor systems, three-phase systems, transformers, loads, DC/DC converters, DC/AC inverters, and AC/DC rectifiers Contains problems at the end of each chapter Supplementary material includes a solutions manual and PowerPoint presentations for instructors Design of Smart Power Grid Renewable Energy Systems, Second Edition is a textbook for undergraduate and graduate students in electric power systems engineering, researchers, and industry professionals.

Energy production and use touch our lives in countless ways. We are reminded of the cost of energy every time we fill up at the gas pump, pay an electricity bill, or purchase an airline ticket. Energy use also has important indirect impacts, not all of which are reflected in current energy prices: depletion of natural resources, degradation of the environment, and threats to national security arising from a growing dependence on geopolitically unstable regions for some of our energy supplies. These indirect impacts could increase in the future if the demand for energy rises faster than available energy supplies. Our nation's challenge is to develop an energy portfolio that reduces these impacts while providing sufficient and affordable energy supplies to sustain our future economic prosperity. The United States has enormous economic and intellectual resources that can be brought to bear on these challenges through a sustained national effort in the decades ahead. "America's Energy Future" is intended to inform the development of wise energy policies by fostering a better understanding of technological options for increasing energy supplies and improving the efficiency of energy use. This summary edition of the book will also be a useful resource for professionals working in the energy industry or involved in advocacy and researchers and academics in energy-related fields of study. "America's Energy Future" examines the deployment potential, costs, barriers, and impacts of energy supply and end-use technologies during the next two to three decades, including energy efficiency, alternative transportation fuels, renewable energy, fossil fuel energy, and nuclear energy, as well as technologies for improving the nation's electrical transmission and distribution systems.

This handbook provides climatological data which can be used as an input for the design of passive solar buildings and solar systems. Solar radiation data are presented for 37 typical European locations, e.g.: -- monthly average global and direct solar irradiation for several surfaces (types of receiver, orientation and inclination), and -- cumulative frequency and utilizability curves of solar irradiance. Ambient temperature data are presented for 186 European locations as monthly average ambient temperatures and monthly degree-days at several base temperatures. A set of methods and algorithms is also given for the reconstitution of these parameters at places where little information is available. Examples of design tools are introduced. The Handbook has been developed within the framework of a European concerted action entitled EUFRAT. Reference is made to a set of computer programmes and data bases which complement the Handbook in a useful way. The Handbook can easily be used by anyone (scientist, engineer, student or even non-specialist) who needs climatic data for the design of systems.
