Obviously, the power generated from geothermal energy is just 0.3% of the total power generation and 1.5% of the power generated from renewables. Compared with solar, wind and hydraulic energy [2], geothermal energy, as an abundant, no CO 2 emission, and stable natural resource, has attracted more attention [7].

Since 2010, the direct use of shallow geothermal energy and underground hot water in China has increased at an average annual rate of 28% and 10% ( Lund et al., 2011 ), respectively, with rapid growth in Beijing, Tianjin, Hebei, and Shandong. This is mainly due to the serious problem of haze in North China.

It is believed that geothermal energy is formed from the decay of material radioactively (Geyer and Quaschning, 2000; Aquatic Energy Renewable Technology (Aqua RET), 2008; Azim et al., 2010). Geothermal gradient is the difference in temperature between the surface of the earth and the core of the earth.
