There is a fundamental relationship between water and electrical power generation, commonly referred to as the energy-water nexus. As the electrification of buildings is pursued as a means to decarbonization, demands on water will increase with it. At the same time, freshwater supplies across the southwestern US have been in long-term decline while demand for water grows with rising populations. This session will describe the energy-water nexus in the context of the southwest generally and the Phoenix area specifically, including how climate change, public policy, and changing technology interact with energy and water.
