Water use of electricity technologies: A global meta-analysis
TL;DR: In this paper, an inventory of the blue water use of power production from existing studies allowed to uncover the characteristics of water use and to investigate current uncertainties, and the results showed that photovoltaics, wind power, and run-of-the-river hydropower consume relatively little water, whereas reservoir and woody and herbaceous biomass can have an extremely large water footprint.
