This National Science Foundation (NSF) bulletin summarizes the NSF program of energy manpower studies that assessed the impact of past energy developments and future options for scientific and technical manpower. This document summarizes the utilization of scientific personnel in energy-related activities in private industry in 1975 and shortages of technical personnel for energy-related activities in private industry. Also, projected needs for science and engineering personnel in energy-related activities are summarized. Graphs and charts are used to illustrate the discussions. Highlights of the report include: (1) Numbers of baccalaureate degrees in mining, chemical, and petroleum engineering have increased in response to job market demand; (2) Projected requirements for scientists and engineers for 1985 in energy production are approximately 220,000; and (3) The energy production sector will not, according to projections, make greater proportionate demands on the supply of manpower as time passes.
