Using limited resources in sustainable ways, energy engineers and technologists have made people's lives comfortable and affordable with efficient and cost-effective technology, from air conditioners to waste fuels. But to accommodate the expanding world population, the global supply of energy has been increasingly strained. Energy efficiency, energy conservation through energy management, and the use of renewable energy sources are three of the major strategies that can provide the energy and energy services for the world's population and economy.Energy managers, researchers, scholars, and policy makers need to know all of the aspects of energy technology in order to tackle this crisis. Encompassing a wide spectrum of theoretical and applied concepts, methodologies, and possible solutions, the Encyclopedia of Energy Engineering and Technology, Three-Volume Set covers energy efficiency and conservation opportunities, renewable and alternative energy sources, the financial analysis of energy systems, performance contracting, environmental regulations, global climate change, green development, hydrogen-fueled vehicles, and much more. Sponsored by the Association of Energy Engineers (AEE), the comprehensive and timely material in this dynamic resource provides precise information that can make a difference in today's quest for energy efficiency.
