At present, the use of global carbon-based energy has caused various ecological problems, and there is an urgent need for a non-carbon-based clean energy that is rich in reserves and can provide stable energy. Geothermal energy is the most suitable among many new energy sources, but its development is subject to the level of economy and science and technology, and many countries have no clear development direction. The paper classifies the geothermal resources according to the different energy storage media, and expounds the basic situation of all kinds of geothermal energy, shallow geothermal, hydrothermal geothermal and hot dry rock are the main body of geothermal application. The main application methods of various geothermal resources are briefly described, including thermal energy utilization and electric energy utilization. Various power generation systems are reviewed in detail, and a new model of multistage utilization of geothermal resources is proposed. In the development of the geothermal industry, the potential problems are analyzed and corresponding solutions are proposed. Government policies should be fully tilted to help enterprises bear investment risks, and increase investment in preliminary survey, technology, equipment and talent reserve. Relevant enterprises and departments need control the cost of geothermal system construction in the early stage. Aim to alleviate the current energy pressure, the research and development group focuses on prioritizing key technologies for shallow geothermal and hydrothermal geothermal mining.
