Geothermal energy; can be defined as the heat energy carried by hot water and steam, which is heated by a magma deep in the earth's crust and contains more melted matter than the normal underground and surface waters around it. In other words, geothermal energy; is a domestic, new, renewable, sustainable, cheap, reliable, environmentally friendly and green energy type that is not dependent on foreign sources. One of the most important features of geothermal energy, unlike other sources produced from underground, is that it has a dynamic structure.

The world population is constantly increasing and technology and industry are developing rapidly. Depending on this situation, the need for energy is increasing day by day with the introduction of electric vehicles. Therefore, it is necessary to increase energy production and energy types in order to meet the energy needs in a sustainable way. The most used energy sources are fossil fuel themed sources. Since fossil fuels are not clean and sustainable energy sources, they cause destruction in the environment. In today's world, where the preservation of ecological balance is increasingly important, minimizing the effects of environmental pollutants is a basic requirement of environmental awareness. For this reason, new, renewable and clean energy sources which do not harm nature and human health have been searched. These energy sources can be listed as geothermal, solar, wind, water and biomass. Among the renewable energy sources, the most important for our country is geothermal energy. Worldwide, geothermal energy is the energy source with the highest potential among renewable energy sources, with an annual potential of 140,000,000 exajoules. Our country ranks fourth in the world in terms of geothermal resources, and 78% of the areas with high potential are in Western Anatolia, 9% in Central Anatolia, 7% in the Marmara Region, 5% in Eastern Anatolia and 1% located in other regions. Geothermal enables the generation of energy from local sources regardless of climatic conditions.

  It is predicted that Turkey's geothermal capacity can theoretically reach 60000 MWt. Our aim is to use high-capacity geothermal energy, which is our own asset, with high efficiency. Therefore, geothermal energy is an ore that should be evaluate as a renewable, sustainable, environmentally friendly and safe energy source.
