Given that fossil fuels will end one day and that these types of fuels produce a lot of pollution, each country should look for new ways to generate energy that is needed for its people in proportion to its energy resources. Given that Iran is geographically located in an appropriate region of the earth, it has a great potential for using renewable energy. In this study, sources and uses of Iranians' geothermal energy have been studied, all of which indicate that Iran has a very good potential for electricity production using geothermal energy. According to the information gathered, Iran has one geothermal energy plant in Meshkin shahr city and this plant power with a capacity of 100 megawatts is an active power plant in Iran. Also, the potential of geothermal power generation was verified in Khoy located in Azarbaijan Gharbi province, Sabalan Ardebil province, Sahand in Azarbaijan Sharghi and Damavand in Tehran province Examination verified that around 8.8% of total land in Iran is capable of geothermal energy production.
