Research progress and prospect of geothermal resources

The world is reducing the use of fossil energy. Reducing carbon emissions will help protect the atmospheric environment. Because geothermal resources are are green, clean and carbon free energy, these are much accounted of by many countries. This paper explains the geological and geophysical characteristics of geothermal resources, summarizes the research of classification and utilization of geothermal resources, and expounds the technical process and difficult problems in the utilization of geothermal resources. It is concluded that if the key problems of geothermal resources utilization are solved, there will be a broad prospect for the utilization of geothermal resources.
