Geothermal energy is a kind of clean, low-carbon, widely distributed, resource rich, safe and high-quality renewable energy, which is usually divided into shallow geothermal energy, hydrothermal geothermal energy and dry thermal rock geothermal energy. Geothermal energy development and utilization has the characteristics of continuous and stable energy supply, efficient recycling and renewable, which can reduce greenhouse gas emissions, improve the ecological environment, play an important role in the future development of clean energy, and is expected to become a new direction of energy structure transformation. According to the 13th five year plan for geothermal energy development and utilization, by 2020, the annual utilization of geothermal energy in China will be equivalent to 70 million tons of standard coal, accounting for about 1.5% of the total primary energy consumption, 1 percentage point higher than that in 2015, and the increment of geothermal energy utilization during the 13th five year plan will account for one third of the increment of non fossil energy. Building the whole industrial chain of geothermal energy and vigorously promoting the development and utilization of geothermal energy can not only increase the proportion of clean energy supply, but also promote the healthy and high-quality development of health care, tourism, breeding and other industries.
