Manual for the Economic Evaluation of Energy Efficiency and Renewable Energy TechnologiesThis manual is a guide for analyzing the economics of energy efficiency and renewable energy (EE) technologies and projects. It is intended to help EE analysts determine the appropriate approach or type of analysis and the appropriate level of detail. It also assists EE analysts in completing consistent analyses using standard assumptions and bases, when appropriate. In addition to containing information on primary economic measures and fundamentals of finance, the manual focuses on the special considerations required in the economic evaluation of EE systems.
This book provides detail and outlook on the comparative advantages and technological progress for using the multiple forms of renewable energy.Renewable energy such as biofuel, solar, wind, hydro, and geothermal are important parts of strategic energy use.It explores the economic and useful benefits of using renewable energy to supply feasible energy supplies worldwide.
The reduction of energy consumption through improvements in energy efficiency has become an important goal for all countries, in order to improve the efficiency of the economy, to increase energy supply security, and to reduce the emissions of CO and other pollutants caused by power· generation. 2 Electric motors use over half of all electricity consumed in developed countries. Typically 60-80% of the electricity which is used in the industrial sector and about 35% of the electricity used in the commercial sector in the European Union is consumed by motors. In industry, a motor consumes an annual quantity of electricity which corresponds to approximately 5 times its purchase price, throughout its whole life of aroun~ 12 to 20 years. Motors are by far the most important type of electric load. They are used in all sectors and in a wide range of applications, namely the following: fans, compressors, pumps, mills, winders, elevators, transports, home appliances, and office equipment, etc. It is their wide use that makes motor drive systems one of the main targets to achieve significant energy savings. As motors are the largest USers of electrical energy, even small efficiency improvements will produce very large energy savings.
