This U.S. Environmental Protection Agency report presents estimates of the energy demand attributable to environmental control of pollution from stationary point sources. This class of pollution source includes powerplants, factories, refineries, municipal waste water treatment plants, etc., but excludes mobile sources such as trucks, and automobiles, and non-point sources such as some types of farms, mines, etc. Energy requirement estimates for water pollution control and for air pollution control are discussed separately. The discussion on water pollution control energy requirements includes: (1) Industrial Water Pollution Control; (2) Control of Thermal Pollution from Electric Power Plants; and (3) Municipal Wastewater Treatment. The air pollution control energy requirement discussion deals with Industrial Air Pollution Control and with Control of SOx and Particulate Emissions from Electric Power Plants. Also included in this document is a comparison of pollution control-related energy estimates, a bibliography, and a summary. This study is a continuation of an earlier effort to estimate the energy required to meet pollution standards for stationary point sources. (Author/MR)
