GAO Reviews the Energy-Water Nexus

From the September 2012 GAO report - - Energy-Water Nexus: Coordinated Federal Approach Needed to Better Manage Energy and Water Tradeoffs (link to the report):

Improved energy and water planning will require better coordination among federal agencies and other stakeholders. GAO’s work has demonstrated that energy and water planning are generally "stove-piped," with decisions about one resource made without considering impacts to the other resource. Improved planning will require federal agencies to work with one another and other stakeholders, such as state and local agencies, academia, industry, and environmental groups. Congress and some agencies have taken steps to improve coordination, but these actions are incomplete or in their early stages. For example, in the Energy Policy Act of 2005, Congress directed the Department of Energy (DOE) to establish a federal program to address the energy-water nexus, but DOE has not done so.
