China's Water-Energy Nexus

By Fredrich Kahrl and David Roland-Holst. As China continues to sustain high rates of economic growth, it is important to better understand patterns of resource use within the Chinese economy and the vulnerability of its growth to resource scarcity. This paper examines relationships between two of China's scarcest resources — energy and water — focusing on the energy implications of water use.

Based on an analysis of economy-wide resource flows using China's input-output tables, the authors draw three overarching conclusions:

  • First, the energy used both directly and indirectly in providing non-agricultural water currently represents only a small fraction of China's total energy consumption. However, this share is set to increase as the country expands its water treatment capacity and hydraulic infrastructure. A lifecycle assessment framework for evaluating these projects would aid policymakers as they choose between more and less energy-intensive modes of water provision.
  • Second, energy-water price interactions are currently of little relevance to policymakers because water prices are low, but the high electricity-intensity of water treatment facilities and their need to recover costs may change this situation.
  • Third, water “migration” from agriculture to non-agricultural uses will have important energy dimensions, which will be important for policymakers to bear in mind as they design water pricing and conservation efforts.
