INTERACTIONS: ENERGY/ENVIRONMENT – Environmental Effects of Geothermal Power - S. J. Goff, P. Brophy, F. Goff 1. Geothermal Systems 1.1. Introduction and History Most prevalent in regions of elevated heat flow and vigorous fluid circulation, geothermal systems occur wherever reservoirs of hot water and steam exist at comparatively shallow depths. These systems occur along or near convergent plate margins, near transform plate boundaries, within spreading centers and rifts, and within hot spots. Geothermal systems commonly produce hot springs and fumaroles as surface expressions of underlying hot reservoirs. Hot and mineral springs have been valued for their therapeutic qualities. Hot springs and fumarole areas have been exploited for sulfur and other minerals. During the Middle Ages, the commercial value of Italian hot spring deposits led to wars among local republics. Electricity was first produced from a steam well at Larderello, Italy, in 1904, and commercial electricity was first marketed in 1913. Since that time, geothermal power has been developed by many countries as an alternative to burning imported or domestic fossil fuels. Commercial geothermal fields produce electricity by piping extracted hot fluids from wells to turbine-driven generators. The focus of this paper is on high-temperature (≥200°C) geothermal systems and flashed steam and dry steam power plants, which represent the majority of current generating facilities. 1.2. Resource Locations and Characteristics Figure 1. Distribution of geothermal resources around the world Geothermal resources are not distributed evenly around the globe (Figure 1), and certain regions are blessed with resources while others are relatively barren. It is not surprising that the ten leaders in generating electricity from geothermal resources (Table 1) are in areas of active volcanism. Today, about 8000 MW of electrical power (the equivalent of ©Encyclopedia of Life Support Systems (EOLSS) UNESCO – EOLSS SAMPLE CHAPTERSPDF Image | Environmental Effects of Geothermal Power
