The main way to use the energy of thermal power, coal, gas, oil and other conventional energy sources, in addition to a small amount of solar and wind energy, the other has not yet been exploited. The use of shallow geothermal energy is a new type of high-quality environmentally friendly energy, in Beijing, Tianjin and other big city has been widely popularized, technology maturity. Shallow geothermal energy is a renewable and large reserves, clean and high availability features, therefore, promote the use of shallow geothermal energy resources, is conducive to optimizing the energy structure of our city, to promote multi can complement each other, improve energy efficiency. First, the basic concept and characteristics Shallow geothermal energy generally refers to the shallow earth hundreds of meters ( 200m) is a kind of low temperature heat contained in soil, sand and groundwater, the energy mainly comes from solar radiation and earth temperature gradient. The shallow geothermal energy resources widely exists in the shallow strata. Table in temperate, less affected by climate, relatively constant temperature, quick regeneration can be recycled. Its main features are as follows: 1. huge reserves According to expert estimates, low energy soil in China each year nearly 100 meters can be collected is 3750 times the current installed capacity of 100 meters
