Energy Demands on Water Resources

Written before hydrofracking became a technological and economic force, Energy Demands on Water Resources; Report to Congress on the Interdependency of Energy and Water written by the U.S. Department of Energy, December 2006, still provides an excellent primer on the energy-water nexus.
 
From the report:

"Therefore, the U.S. should carefully consider energy and water development and management so that each resource is used according to its full value. Since new technologies can reduce water use, there will be a great incentive for their development by the public and private sectors. Given current constraints, many areas of the country will have to meet their energy and water needs by properly valuing each resource, rather than following the current U.S. path of largely managing water and energy separately while making small improvements in freshwater supply and small changes in energy and water-use efficiency."

 

The key words for engineering - - "full value."  This is the link to the report.
