Abstract
This paper tries to estimate and predict the water demand of China’s energy industry in 2012,2020 and 2030 by studying the current water usage of the energy industry and the development trend. The results showed that: in 2020 and 2030, the water demand of China’s energy industry will reach 655×108 m3 and 677×108 m3 respectively,which is a minute increase, less than 20% compared to that in 2012 (about 573×108 m3). This meant the water requirement of energy industry development in China can be guaranteed. Thermal power generation will remain the largest consumer, taking over 75% of the water consumption of energy industry. While developing rapidly,wind power generation,nuclear power generation and solar power generation will not consume a large amount of water. Shale gas has become a new bright spot in the development of China’s oil and gas resources exploration, and the water demand in this sector is negligible compared to the total water demand for energy, though water usage concentrated in a short term of its early exploitation may affect other sectors around the mining regions. The water demand of energy crops,which will increase by 30×108 m3 from 2012 to 2020 and 18×108 m3 from 2020 to 2030, would be a major factor of the increasing water demand of energy industry in the future.
