A compendium of information about costs and quantities of energy resources that may be available to the United States through the 1980s. Data, compiled from a review of the published material available through early 1974, were used to calculate long-run marginal costs as represented by the cost of an incremental plant, mine, tanker, pipeline, etc., earning a "normal" rate of return on investment and operating at planned capacity. The following activities were judged to be most important in the near-term national energy situation for the purpose of determining costs: crude oil production (lower-48, Alaskan, foreign) conveyance by pipeline and tanker, refining, and distribution; natural gas production (lower-48, Alaskan), transmission, and distribution; syncrude production from domestic shale, transmission, and refining; coal production (surface and underground--eastern and western--high and low sulfur) and transportation; central station electric power generation (nuclear- and fossil-fueled), transmission, and distribution; and nuclear fuel production and reprocessing. 229 pp. Ref.
