This module is the first in a series of eleven modules in an energy conservation curriculum for secondary and postsecondary vocational students. It is designed for use by itself, to be integrated with the other ten modules into a program on energy conservation, or to be integrated into conventional vocational courses as a unit of instruction. The objective of this module is to instill awareness that there is a growing crisis in energy supply. First, an introduction to the module and definitions of key terms are provided. Next, the text is presented in the following two units: (1) an overview of energy supply sources, including oil, gas, coal, nuclear, and hydro-electric power; and (2) a discussion of potential of alternate energy sources such as solar power, wind, geothermal, tidal power, ocean thermal, and biomass. The information in each unit is presented in lecture format accompanied by laboratory exercises and question/examples for class discussion. A bibliography and several charts illustrating the text material are found at the end of the module. (BM)
