Water use of electricity technologies: A global meta-analysis
The use of water in the electricity system can be assessed using multiple metrics. The most common measure is the volumetric water footprint. It includes direct (i.e. water use for cooling at the point of generation) and indirect water use (i.e. upstream water use in the supply chain of fuels or equipment).
