Solar Energy Efficiency

The transformation from a carbon-based world economy to one based on high efficiency and renewables is a necessary step if human society is to achieve sustainability. But while scientists and researchers have made significant advances in energy efficiency and renewable technologies in recent years, consumers have yet to see dramatic changes in the marketplace-due in large part to government policies and programs that favor the use of fossil fuels. Energy Revolution examines the policy options for mitigating or removing the entrenched advantages held by fossil fuels and speeding the transitionto a more sustainable energy future, one based on improved efficiency and a shift to renewable sources such as solar, wind, and bioenergy. The book: examines today's energy patterns and trends and their consequences, describes the barriers to a more sustainable energy future and how those barriers can be overcome, provides ten case studies of integrated strategies that have been effective in different parts of the world, examines international policies and institutions and recommends ways they could be improved reviews global trends that suggest that the transition to renewables and increased efficiency is underway and is achievable Energy policy represents a linchpin for achieving a broader transition to a more sustainable economy. Energy Revolution offers a unique focus on policies and programs, and on the lessons provided by recent experience. It represents a key statement of the available options for reforming energy policy that have proven to be successful, and is an essential work for policymakers, researchers, and anyone concerned with energy and sustainability issues.

Fundamentals of Building Energy Dynamics assesses how and why buildings use energy, and how energy use and peak demand can be reduced. It provides a basis for integrating energy efficiency and solar approaches in ways that will allow building owners and designers to balance the need to minimize initial costs, operating costs, and life-cycle costs with the need to maintain reliable building operations and enhance environmental quality both inside and outside the building. Chapters trace the development of building energy systems and analyze the demand side of solar applications as a means for determining what portion of a building's energy requirements can potentially be met by solar energy. The approach taken is a commonsensical one, starting with the proposition that the purpose of buildings is to house human activities, so that conservation measures that negatively affect such activities are based on false economies. The goal is to determine rational strategies for designing new buildings and retrofitting existing buildings to bring them up to modern standards of energy use. The energy flows examined are both large scale (heating systems) and small scale (choices among appliances.).

Passive solar - Passive solar design is a broad category of solar power techniques and strategies for regulating a building's indoor air and domestic water temperatures, using climate, site features, architectural elements, and landscape materials. The goal is typically to increase the comfort, efficiency and reliability of a building, while reducing its operating costs and dependence on other sources of energy for heating and cooling.

Energy efficiency - In physics and engineering, including mechanical and electrical engineering, energy efficiency is a dimensionless number, with a value between 0 and 1. The energy efficiency of a process is defined as:

Solar thermal energy - The major applications of solar thermal energy at present are heating swimming pools, heating water for domestic use, and space heating of buildings. For these purposes, the general practice is to use flat-plate solar energy or evacuated tube collectors with a fixed orientation (position).

Reuven Ramaty High Energy Solar Spectroscopic Imager - Reuven Ramaty High Energy Solar Spectroscopic Imager (or RHESSI) is a NASA sixth Small Explorer, launched on 5 February 2002. Its primary mission is to explore the basic physics of particle acceleration and explosive energy release in solar flares.
