Abstract: The relationship between water and energy is complex and close, and their correlation has become a hot issue concerned by international society. In this paper, we try to explore the inherent correlation between energy production and water utilization with spatial autocorrelation analysis and decoupling analysis of energy-consumption water in order to provide a reference for the sustainable development between water and energy. The results show that the water consumption of major energy had different spatial distributions, and the distribution of water consumption had the similar characteristics as that of the energy itself. Regional energy production had strong dependence on local resources. Water consumption of thermal power, hydropower and coal had significant characteristics of spatial clustering. The range of H-H concentrated areas was gradually expanding, and concentration degree was also growing. This indicated that water use efficiency in the production of these three kinds of energies was generally low, and the spatial diffusion trend of this effect exacerbated the tension of water utilization. Water consumption of crude oil and natural gas was in random pattern and had no spatial autocorrelation. Decoupling analysis between energy-consumption water & total water consumption and energy-consumption water & GDP showed that the coordination relationship between energy-consumption water and total water consumption was better than the coordination relationship between energy-consumption water and GDP, but they all showed a deteriorating trend nationally. The growth rate of energy-consumption water was gradually surpassing the rate of economic development and the change rate of total water utilization. It played a warning role water consumption of energy. In the future, inhibiting the growth of water consumption by technical innovation would become an important direction in water consumption of energy production.

Key words: decoupling analysis, energy-consumption water intensity, GDP, spatial auto-correlation analysis, total water consumption, energy-consumption water
