Coal will be the leading source of energy in the United States by the year 2000, and it will be consumed primarily in the form of liquids and gases. Edward A. Frieman, director of energy research for the U.S. Department of Energy (DOE) offered these projections in a recent briefing to representatives of U.S. scientific and engineering societies.

Renewable forms of energy (solar, biomass, and hydroelectric) are expected to reach only half of the 20% share projected in recent years.
