Four energy conservation concept areas are developed in this unit: (1) energy resources are many and varied and have evolved over a long period of history; (2) as much as 30 to 50 percent of the energy in the United States is wasted; (3) homes, offices, and schools account for 24 percent of total energy consumption and savings can be made through such methods as increasing home insulation; (4) transportation accounts for 25 percent of total energy consumption and savings can be made through such methods as reducing automobile size. Several activities accompany each of these concept areas. Each activity includes: the related concept; materials needed; suggested procedures; and expected results. Supporting documentation, including lists of informational services and publications (with addresses) are included in appendices. Although the unit is designed for junior high school students, it can be easily adapted to elementary and high school levels. (ML)
