Over the next five years, China will intensify the development and utilization of shallow geothermal energy 200 meters or less underground in the construction industry, and a strict supervision system will be established to regulate procedures such as the review and approval of mining licensing, according to the Ministry of Land and Resources.
In 2008, China reduced carbon dioxide emissions by over 25 million tons through the development and utilization of geothermal resources, reporters learned from a recent national shallow geothermal energy and geothermal resources management conference.
It is understood that at the end of June 2009, China was already using shallow geothermal energy to supply heating and refrigeration to a total of 2,236 construction projects covering up to 80 million square meters of construction sites. Of those, 80 percent were located in North China in Beijing, Tianjin, Hebei and Liaoning and other places, as well as in southern Northeast China.
Shallow geothermal energy is low-temperature heat energy stored in soil between 200 meters underground and the surface. It has extensive distribution, huge reserves, is rapidly renewable and has significant development and utilization value. Wang Min, vice minister of Land and Resources, noted that in the recent years, the ministry has carried out investigations and evaluations on geothermal resources of China's thermal springs and key regions and has discovered a group of medium and high-temperature geothermal fields.
