This publication is a summary of the world energy situation and its impact on the United States. A brief review of some interrelated diplomatic, commercial, and technical aspects of the energy crisis and their implications for the U.S. and its foreign policy is presented first. Next, discussions of world supplies, uses and problems with different fuels including fossil fuels, solar, wind, nuclear, and geothermal are given. The distinction is made between resources and reserves. Finally, a concluding discussion is given that indicates what direction U.S. foreign policy on energy should go. It is suggested that the U.S. should play a major role in bringing the world through the transitional period ahead. (MR)
