Energy plays an important role in the economic development of any country. Topics covered in Energy Management, Conservation, and Audit range from the current energy situation to the methodology behind energy audits and management, with real-world examples from various industries. Life cycle assessment, pricing, and rate of return are some of the ideas that have been developed to better understand the energy economics of systems. Efficiency in the energy sector has been explored with other related topics such as energy storage, co-generation, and the recycling of waste heat. With advances in lighting technology have come greater complexities in the problems of energy conservation (steam and electricity). In addition, it discusses methods for optimizing energy-related technological progress. Energy management, sustainable energy, renewable energy, energy audits, and energy conservation were the main areas of study for the researchers, upper-level undergraduates, and postgraduates.
