Bangladesh has the world s fastest growing off-grid solar home system coverage, yet only 10% of mainly rural households have so far benefited. A key policy issue is whether the partial subsidy provided under the current program should be continued and this study highlights how the social benefits far exceed the cost of the subsidy.

How solar could spark a clean-energy transition through transformative innovation—creative financing, revolutionary technologies, and flexible energy systems. Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless—every hour the sun beams down more energy than the world uses in a year. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim. Innovation can brighten those prospects, Sivaram explains, drawing on firsthand experience and original research spanning science, business, and government. Financial innovation is already enticing deep-pocketed investors to fund solar projects around the world, from the sunniest deserts to the poorest villages. Technological innovation could replace today's solar panels with coatings as cheap as paint and employ artificial photosynthesis to store intermittent sunshine as convenient fuels. And systemic innovation could add flexibility to the world's power grids and other energy systems so they can dependably channel the sun's unreliable energy. Unleashing all this innovation will require visionary public policy: funding researchers developing next-generation solar technologies, refashioning energy systems and economic markets, and putting together a diverse clean energy portfolio. Although solar can't power the planet by itself, it can be the centerpiece of a global clean energy revolution. A Council on Foreign Relations Book

Passive solar heating and passive cooling—approaches known as natural conditioning—provide comfort throughout the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from breezes is free for the taking, few modern architects or builders really understand the principles involved. Now Dan Chiras, author of the popular book The Natural House, brings those principles up to date for a new generation of solar enthusiasts. The techniques required to heat and cool a building passively have been used for thousands of years. Early societies such as the Native American Anasazis and the ancient Greeks perfected designs that effectively exploited these natural processes. The Greeks considered anyone who didn't use passive solar to heat a home to be a barbarian! In the United States, passive solar architecture experienced a major resurgence of interest in the 1970s in response to crippling oil embargoes. With grand enthusiasm but with scant knowledge (and sometimes little common sense), architects and builders created a wide variety of solar homes. Some worked pretty well, but looked more like laboratories than houses. Others performed poorly, overheating in the summer because of excessive or misplaced windows and skylights, and growing chilly in the colder months because of insufficient thermal mass and insulation and poor siting. In The Solar House, Dan Chiras sets the record straight on the vast potential for passive heating and cooling. Acknowledging the good intentions of misguided solar designers in the past, he highlights certain egregious—and entirely avoidable—errors. More importantly, Chiras explains in methodical detail how today's home builders can succeed with solar designs. Now that energy efficiency measures including higher levels of insulation and multi-layered glazing have become standard, it is easier than ever before to create a comfortable and affordable passive solar house that will provide year-round comfort in any climate. Moreover, since modern building materials and airtight construction methods sometimes result in air-quality and even toxicity problems, Chiras explains state-of-the-art ventilation and filtering techniques that complement the ancient solar strategies of thermal mass and daylighting. Chiras also explains the new diagnostic aids available in printed worksheet or software formats, allowing readers to generate their own design schemes.

Now more than ever, the question of economic and environmentally friendly energy sources has become a hot topic in almost every American home. With that in mind, more and more people are turning to alternatives such as solar power as a means of saving money and reducing their imprint on the environment. This nearly carbon neutral method comes with hefty tax rebates from the federal government and in states like California and New Jersey massive rebates from the state. More states are considering similar rebates and with a 3 to 8 year energy savings possible according to a recent report by the New York Times, it is an ideal solution for anyone looking to save money in the long term and help the planet immediately. This book will guide anyone interested in the process of installing and utilizing solar power for their home in the process of searching for, buying, or building their own solar power system. Learn how solar power and other alternative energy sources can help to save the world regardless of the cost and how you can start surveying your own energy use and efficiency. Learn how you can start making basic adjustments to become more efficient and how solar power can help you before you start any major projects. Learn what solar power requires, from cost and equipment to maintenance and preparation in certain times of the year. Learn how solar power works and how to start evaluating the potential of it for your building needs. Take the cost of installing solar power and learn how long it will take to make money back on your investment, including information on federal and state rebates that might affect you. Multiple individuals who have successfully installed solar power in their homes have been interviewed and their experiences included in this guide to help you learn what others go through and how they came out. Learn how the installation process works and how it can be done in your landscape, in small projects, for heating and purifying water, swimming pool heating, and other smaller projects. Learn about how individuals construct solar power systems on their own to save money and what is involved in a full PV system. Finally, learn how the market for green homes has made it possible to extract a huge return on investment from building or remodeling a home with solar power. For anyone who has ever considered solar power as a viable means to save money and the environment, this guide will help you get started right away.br> Atlantic Publishing is a small, independent publishing company based in Ocala, Florida.
