Statistics, for the world total reserves of geothermal power generation (temperature exceeds 150 ) is 11000 ~ 13000 (TW? H) / a, the direct use of geothermal potential (temperature lower than 150 ) 390000 (TW? H) / a. More information on geothermal energy reserves, including proved and unproved geothermal energy. Stefansson estimated proven geothermal energy for electricity generation in each of 2000 140TW? H, the direct use of geothermal energy to 7000 (TW? H) / a. Geothermal energy for electricity generation at present is 49 (TW? H) / a, the direct use of geothermal energy is 53 (TW? H) / a, obviously the use of geothermal energy currently accounts for proved reserves of geothermal energy is small part. Whether used for power generation or direct use of geothermal energy use still considerable room for development.
2) environmentally friendly geothermal power generation will have a strong development prospects. Swiss energy scientist Willy? Eagle or even considered, geothermal power capacity in 20 years of total world electricity generation will be 10%.
3) compared with geothermal power and direct use of geothermal energy with up to 50% ~ 70% efficiency, and geothermal power is 5% to 20%. Chinese low-temperature geothermal resource-rich, direct development and utilization of a broad prospect. Therefore, actively direct use of geothermal resources more appropriate to national conditions of China.
4) Heat Pump Are gradually being attention, the U.S., Germany, Switzerland, Sweden and France and other countries are stepping up promotion of the application of heat. In recent years, the heat pump application in Beijing there have been unprecedented good situation, this advanced technology is widely accepted by society, the new heat pump Project The installation continue. But, compared to these countries, China still in the initial stages of heat pump applications, the main gap is reflected in the project design. China heat pump system design is generally carried out in the light of experience, lack the necessary geotechnical properties Test And calculating, often cause problems to the system design, resulting in a waste underground installation or inadequate. Therefore, it should be the introduction of advanced technology and experience the country, strengthen basic research, making China the heat pump application to science and sustainable track.
5) based in Rio de Janeiro (1991) and Kyoto (1997) held in the United Nations Conference on the environment, the provisions of the European Community in 2008? 2012, caused by greenhouse gas emissions to below 1990 emission levels 8%. This prompted the European intensify, including geothermal energy, Solar Energy , Hydro and wind energy, including research and development of new clean energy sources. With the rapid and stable development of China's market economy and building a moderately prosperous society will greatly enhance the degree of urbanization, and the people for Life Quality, environmental quality requirements will greatly increase the demand for geothermal energy market will be more robust. Geothermal development should be combined with the region Geography Environmental and economic characteristics of market-oriented, Technology Based on innovation, on the level of the grade, the scale of the formation of industry to achieve social, economic and environmental benefits optimization.
As people's awareness of the environment, use of geothermal energy can reduce greenhouse gas emissions, geothermal energy and sustainable exploitation of rich reserves of the characteristics of geothermal energy production in the next few years will play an important role, as can be regeneration of green options.
