内容摘要

Water is one of the essential inputs for traditional electricity generation technologies including coal-fired power. We match the plant-level information with the meteorological data between 2007 and 2014 to examine how water scarcity affects the technology selection for electricity generation in China. We find that drought decreases the electricity generation from hydro technology largely, while the fossil-based technology increases in response to water scarcity. For fossil-based technology, once-through system and wet-recirculating system are favorable for cooling when drought happens. Drought also increases the use of surface water and wastewater for cooling. The results are robust when considering the annual, seasonal, and monthly climate variations. We also show that water scarcity increases CO2 emissions. We conclude that water scarcity mitigates the effort of energy transition towards renewable.
