Abstract
Saudi Arabia is enriched by geothermal resources and related to the tectonic activity of Red Sea, volcanic rocks and ridges. The geothermal energy reserve, potential and their reserve for possible energy production are investigated. Nowadays, production process of crude oil accompanied with flaring of gases result in excessive CO2 emissions. If the growth rate of national oil consumption continues, local demand will be doubled within a decade. The study of geothermal energy is covered. A selection of possible applications of geothermal futures is discussed. Furthermore, the study has focused on necessity of maintaining green and clean environment as well as climate of lowest dust content.
