Nowadays, Geothermal energy certainly doesn’t have the popularity of wind and solar power. It is a renewable energy that deserves tremendous support. Most are found in the Group of developed countries, there are a lot of investment. Compared to other energy. In 2008, the United States can generate electricity from geothermal energy, more than any other country in the world. But accounted for only 0.4% of total US energy (Needtoknow.nas.edu, 2015). Until recently, renewable energy technologies represent only a small fraction of the power system of the United States. Although, in recent years, renewable energy has become a part of the increase to the table to generate about 14% of electricity generation in the United States at the end of June 2013 with wind, solar and geothermal generating about 5% of the electric power. In the wind and solar energy generation is an important and innovative technology is featured in the role changed to a clean energy economy. It also helps to relieve the important effects of global warming. However, wind and solar energy must rely on the weather that occurs in their production. A change in wind patterns, or the day the clouds will affect the availability of these models are the result of technology. At the same time, geothermal energy is a renewable energy source can be provided baseload this means they can work in hot or cold. And do not depend on changes in factors such as the status of the wind or the sun. Geothermal power plants produce electricity. Or heat 24 hours a day, 7 days a week. (Society & Society, 2012) and flexible power, quickly adjusting to fit the needs set by variable renewable energy technologies.
