This document discusses the energy-water nexus and the United Nations Sustainable Development Goals (SDGs). It summarizes that achieving SDG 6 on clean water and sanitation will require significant energy, while energy production requires large amounts of water. Meeting climate targets under SDG 13 may not be possible without proper water resource management. Decentralized renewable energy may help provide access to energy and water in overlapping areas currently without either. Key ongoing work includes analyzing the energy needs to meet water and sanitation targets, identifying solutions that achieve multiple SDGs, and increasing efficiency of water use in the energy sector.
