Abstract

:The geothermal energy is the heat energy generated from the radioactive decay of minerals and stored in the earth. These geothermal resources are more than adequate to supply all human energy needs for many years. Only few numbers of sources are used so far.this geothermal heat source is converted into the geothermal electricity directly. These geothermal sources ate in different forms as hot water, dry hot steam, and hot rock. Depending upon the types of sources there are different types of plants were set and installed. They are single, double flash power plants, binary power plants and dry steam plants. The enhanced geothermal system is seen without the use of the natural convective hydrothermal resources. which represent a path for turning the enormous resources provided by geothermal energy into electricity for human consumption efficiently and on a large scale. This method consists of excavation of deep rocks, enhanced heat extraction from rock, enclosed heat transmission from heated water reservoir to the power plant. The enhanced geo thermal systems generate the geothermal electricity without the need of the natural convective resources. Induced seismicity is expected in the EGS Which involves pumping fluids to enhance or create permeability through the use of hydraulic fracturing techniques.
