Abstract

Mortality of Fossil fuels, sustainable development and environmental problems caused by the use of fossil fuels, on the one hand, and the renewables of new energy sources on the other, have led the world to develop renewable energy. Geothermal energy has significant advantages over other renewable energies, such as lack of dependence on weather conditions, sustainability and permanence, high utilization in most areas, and high thermal efficiency. At present, the installed capacity of geothermal energy for power generation by end of 2017 will reach 14060 MW and direct use will reach 70329 GW by the end of 2015. In this study, according to the growth in using of this energy of the last few years, has been predicted to achieve the global capacity of installed electricity to 20 GW (0.532% of the world's total electricity consumption) by 2030. The use of geothermal energy to produce 175.25 TWh of electricity makes it unnecessary to use significant amounts of different fossil fuels (Coal: 8.185×1010 Kg, Natural Gas: 4/975×1010 m3 and Oil: 2.8×108 barrel). If these fossil fuels were used to produce the same amount of electricity, much carbon dioxide would enter the atmosphere (by using Coal: 234.091×106 tone CO2, Natural Gas: 97.957×106 tone CO2 and Oil: 121.158×106 CO2).
