Energy's thirst for water in China

Water scarcity and uneven water distribution pose significant challenges to sustainable development and energy production in China. Based on the International Energy Agency (IEA)'s energy strategy scenarios for China, we evaluated the water withdrawal for energy production from 2011 to 2030. The results show that the amount of water withdrawal will be increased by 77% in 2030, which will aggravate China's water scarcity risk under current energy strategy. We also observed that 67% of the energy production in China occurs in areas that are facing water scarcity. Moreover, China's 12th Five-Year Plan of Energy Development does not change the existing energy strategies, and the planned total energy production is much higher than the IEA's projection, which will result in an increased demand for water resources. However, if China were to apply broad policies to reduce CO2 emissions, the amount of water withdrawal would also decline compared with current energy strategy. Thus, reforming China's energy structure and reducing energy usage are not only urgent because of climate challenges and air pollution but also essential to reducing the pressure of water scarcity.
