Save Energy To Save Water?—Possible But Need More
by China Water Risk 28 May, 2013
28 May 2013 – Tsinghua University and Natural Resources Defense Council(NRDC) jointly announce research results of “Evaluation on Water Saving Efficiency of China’s Energy Saving Policies” and calls for more effort to create synergies and effectiveness between climate change and water policies in the future.
The report indicates the four major users of water in China during 11th FYP with breakdown of their average annual water usage:
- Agriculture: 36.62 billion m3 (64.4%)
- Industry: 12.81 billion m3 (22.5%)
- Consumption: 67.2 billion m3 (11.8%)
- Ecological Protection: 9.95 billion m3 (1.7%)
Moreover, the report reveals that during 11th FYP, thermal power directly saves 10.56 billion m3 of water as a result of energy saving policies.
The report also estimates the effectiveness of energy-saving policies of the 12th FYP that:
- Oil processing: Increase in energy consumption by 8%
- Cement: Decrease by 18%
- Paper: Decrease by 20.89%
While the estimated coal consumption for top 5 water-intensive industries during 12th FYP is 146 million tonnes, the new energy-saving policies will approximately save 17.07 billion m3 of water directly from these industries, and 42.92 billion m3 will be saved from the industries related to these 5 industries. According to the report, China’s top 10 high water consumption industries are:
- Production and supply of electricity and heat
- Ferrous metal processing
- Chemical materials and products
- Oil processing/coke/nuclear fuel processing
- Paper and pulp
- Chemical fiber
- Non-ferrous metal Processing
- non-metallic mineral products
- Agri-food processing
