Although these are more expensive, they do have the advantage of being able to heat the water to a higher temperature for more of the solar year. Their one main disadvantage is that often an electric pump needs to be employed to circulate the water.
Passive solar is simply setting up a property so that maximum use of made of the natural solar energy to reduce heating and cooling costs. See this article for more information on how to do it.
Going Solar contains everything that a budding or experienced solar enthusiast could wish for. By distilling thousands of years of history and knowledge into one book, Tomm Stanley brings together the work of pioneering solar designers, some of the greatest scientists that the world has known and a range of modern, practical applications for hands-on people to create a delicious brew of thought provoking, solar thermal discussion.
Enthusiastically coaxing readers through the essential concepts at work in fields of study as diverse as history, geography, nuclear physics, thermodynamics and astronomy, Going Solar reveals the "how's" and "why's" behind the solar heating phenomenon. When the subject matter turns to a study of devices that use solar heat, readers have a firm grasp of the natural forces at work and an appreciation of how the technology might be applied in their own lives.
Written in easy-to-understand language for everyday people and the scientifically challenged, Going Solar contains a delightful blend of humor, fact and function that continually guides readers back to the purpose of its making; understanding and effectively using the warmth found in sunlight for our day-to-day lives.
If millions of people in the developing world can use solar power, why can't we? The question immediately arises from this fascinating account of the author's 12-year quest to bring solar power and light to people in the developing world who have no electricity.
Chasing the Sun is a story of dreamers and doers who succeeded in their mission to make the world better by delivering nature's energy to poor people and by building organizations to put the sun at their service in practical, affordable, and effective ways. A green energy development narrative that is fun and eye-opening, the book is also part autobiography. Author Neville Williams' inspiring tale of trailblazing innovation describes:
His founding the nonprofit Solar Electric Light Fund (SELF) in 1990, which promoted solar power for a decade by setting up pilot solar rural electrification programs in 11 developing countries, including Zimbabwe, India, Nepal, Vietnam, Sri Lanka, and China
His launching of the commercial Solar Electric Light Company in 1997, which became the SELCO group of companies that has overcome daunting challenges to bring solar electricity to 50,000 families in India, Sri Lanka, and Vietnam
Filled with colorful characters, the book also features the enthusiasm of maverick devotees to the renewable energy boom of the 1980s and 1990s and their interplay with staid DC-based development institutions, as well as their unique perspective on global solutions to "energy poverty." It will be illuminating to all interested in the environment, development, renewable energy, socially responsible business, and our future at the end of the age of oil.
The coming energy crisis caused by a peak in global oil and natural gas production will profoundly affect the lives of all North Americans. As the price of these vital fuels rises, homeowners will scramble to cut their fuel bills. Two options for meeting the upcoming challenge are dramatic improvements in home energy efficiency and efforts to tap into clean, affordable, renewable energy resources to heat and cool homes, to provide hot water and electricity, and even to cook. These measures can result in huge savings and a level of energy independence.
The Homeowner's Guide to Renewable Energy tells you how. It starts by outlining the likely impacts of fossil fuel shortages and some basic facts about energy. It then discusses energy conservation to slash energy bills and prepare for renewable energy options. Focusing carefully on specific strategies needed to replace specific fuels, the book then examines each practical energy option available to homeowners:
