Examined in this American Petroleum Institute (API) publication on energy technology and energy policy, is the future potential of oil, natural gas, coal, nuclear energy, synthetic fuels, and renewable energy resources. Among the related issues emphasized are environmental protection, access to federal lands, government policies, and the national benefits of reducing energy imports. By developing domestic resources more efficiently and consuming energy more wisely, the API contends that the United States can reduce its oil imports by as much as 50% between 1980 and 1990. Analyses of the nation's energy past, present, and future are presented together with future policy choices. (WB)
