Water use in China’s coal power plants
Published in Xiawei Liao, Jim W. Hall, Water Management in China’s Power Sector, 2020
The coal power sector is the major source of air pollution and greenhouse gas emissions in China due to its intensive coal combustion. Facing pressing local health impacts and global climate change pressures, China has taken actions to reduce its power sector’s reliance on coal by either transforming its energy portfolio or improving coal-burning efficiencies. Such policies can generate co-benefits of water savings. For example, Webster, Donohoo and Palmintier (2013) found that a restriction on CO2 emissions in the energy sector would also reduce water withdrawals by the power sector in Texas; Bartos and Chester (2014) have shown that Arizona’s Energy Efficiency Mandate and Renewable Portfolio Standard have resulted in considerable water savings.

Crop yields are also affected by climate change in China (Tao et al. 2013). Tao et al. (2006) studied the trends of maximum temperature, minimum temperature and precipitation and their effects on the yield of major crops in China based on Chinese meteorological data, phenology and yield data from 1981 to 2000. The analysis showed that significant warming trends have been observed in most meteorological stations in China, and changes in temperature over the past 20 years have altered the phenology of crops and affected their yields; Furthermore, climate change leads to an increase in extreme heat, and the resulting reduction in crop yields is also likely to increase (Tao et al. 2013). In summary, most studies have shown that the increase in temperature has a great impact on rice, and with the increase of temperature, the yield of rice has decreased.
