Future Air Quality Maintenance and Improvements Through the Expanded Use of Geothermal Energy

Abstract

Geothermal development projects have experienced considerable slow down due to a combination of factors including the State of California change from a deficit to a surplus electrical generator and the low cost of imported oil. Environmental factors which are estimated to combine to change this situation and stimulate future geothermal growth are presented. The association between energy use and production and global air pollution which is prompting local, state and federal agencies to explore alternatives to fossil fuels use is described. All forms of fossil fuel use either in stationary sources such as electrical power plants or in mobile use such as in transportation are shown to be producing unacceptable quantities of air pollutants. The discussion includes infrared absorbing gasses, acid rain, ozone formation, hazardous waste generation and air toxics. Agencies' strategies for maintain and improving air quality in the future are discussed. An expanded role and opportunity for geothermal energy use is forecast if its inherent environmental advantages are utilized.
