Geothermal energy has an important role as a renewable and clean energy source worldwide. Geothermal energy is obtained by using hot water and steam deep underground. This energy source has many advantages and is used in various fields. Here is the importance of geothermal energy: Clean and environmentally friendly: Geothermal energy is a cleaner energy source than fossil fuels. During geothermal energy production, no harmful gases are released into the atmosphere and it has minimal impact on the environment. This contributes to reducing air pollution and combating global climate change. Renewable and sustainable: Geothermal energy is a constantly renewable resource. Hot water and steam underground can be produced indefinitely. This makes geothermal energy a sustainable energy source. Economic benefits: Geothermal energy provides economic benefits in the long term. Since geothermal energy resources are generally found locally, they can reduce dependence on energy imports and contribute to the local economy. Various areas of use: Geothermal energy can be used in various areas such as electricity generation, heating and cooling systems, greenhouse agriculture and industrial applications. This shows that geothermal energy is a versatile energy source. Considering these advantages of geothermal energy, it is important to further use and develop this clean and sustainable energy source. Geothermal energy can play an important role for a sustainable future by protecting the environment while meeting energy needs.
