Abstract: Significant energy resources are used for water supply in Jing-Jin-Ji region with the rapid urbanization and economy increase. Yet the interrelations between water and energy have not received adequate attention in the country. In order to fill this gap, this paper performs a regional-level quantitative assessment of electricity consumption on water produce (including water extraction, desalination and recycled water reuse), as well as analyzed carbon dioxide emission caused by energy used in 2015. The results show that total energy consumption for water supply amounts to 255.63 million kWh of electricity, and 0.27 million ton of carbon released in water supply progress. Due to the differences in water supply structure and water use amount, the energy consumption and carbon release of water supply in Hebei province is higher than Beijing and Tianjin city. Given increasing water supply demand, the implementation of the most stringent water management system may increase the energy consumption, and the trend of future climate change is not conducive to the conservation of water resources and energy in Jing-Jin-Ji.
