Energy and water have become major factors limiting sustainable development in China. Energy efficiency and optimization of water management are critical for the healthy growth of the Chinese economy, Current national energy policies fail to adequately address water use issues. Similarly, current water policies do not consider the impact of energy consumption and greenhouse gas emissions. Consequently, few studies have investigated the relationship between energy consumption and water use. The present study analyzes the energy-water nexus in Chinese industries using input-output tables. Coefficients that characterize the relationship between energy consumption and water are used to describe the supply-consumption relationship between the water supply and primary energy sectors. Next, we calculate the water-saving effects associated with the enforcement of energy-saving policies in selected industrial sectors during the eleventh Five-year Plan, from 2005 to 2010. These calculations address the ferrous metals, non-ferrous metals, petrochemical engineering, building materials, and electricity industries as well as key light industries. Our findings indicate that energy-saving efforts in these industries will result in savings in water consumption. This study suggests that a cooperative relationship between water and energy conservation efforts should be an important factor in creating policies that encourage simultaneous savings of both resources. Additionally, the study indicates that government should promote water- and energy-saving techniques in key industrial sectors to encourage cooperative water and energy conservation.
