Almost three years ago, I wrote a post about 'water consumption in electricity generation using different technologies' (http://j.mp/Water_Power_Nexus). However, indeed, I didn't have to collect those data. Two very good papers on the topic had been published by researchers from the National Renewable Energy Laboratory.
(Paper 1: Macknick, J., Newmark, R., Heath, G., & Hallett, K. C. (2012). Operational water consumption and withdrawal factors for electricity generating technologies: a review of existing literature. Environmental Research Letters, 7(4), 045802. [Full-text at http://dx.doi.org/10.1088/1748-9326/7/4/045802]
Paper 2: Meldrum, J., Nettles-Anderson, S., Heath, G., & Macknick, J. (2013). Life cycle water use for electricity generation: a review and harmonization of literature estimates. Environmental Research Letters, 8(1), 015031. [Full-text at http://dx.doi.org/10.1088/1748-9326/8/1/015031])
Nowadays, the nexus between energy and water seems to have become an even more popular topic in the United States. Over the past two months, three notable U.S. institutions published lengthy reports on the issue. The reports are:
Rogers, J., Averyt, K., Clemmer, S., Davis, M., Flores-Lopez, F., Frumhoff, P., Kenney, D., Macknick, J., Madden, N., Meldrum, J., Overpeck, J., Sattler, S., Spanger-Siegfried, E., & Yates. D.
