ABSTRACT
This chapter describes the primary as well as derived energy sources. The objective is to provide information on the extent, availability, measurements and estimation, properties, and limitations of each type of resource. These considerations are important for an engineer to know and understand before attempting selection and design of an energy conversion system. The chapter also includes environmental impacts of energy resources since the environmental aspects are expected to play a major role in the selection of energy resources. In addition, there is a brief discussion of the costs associated with each resource to help in the economic analysis and comparison of the resources.
