The estimates put total withdrawals at lowest level since before 1970, following same overall trend of decreasing observed from 2005 Freshwater were 281 Bgal/d, or 87...
Estimates of water use at thermoelectric plants were developed by the U.S. Geological Survey based on linked heat and budgets, complement reported withdrawals consumption. The heat- water-budget models produced withdrawal consumption estimates, including thermodynamically plausible ranges minimum maximum consumption, for 1,290 water-using in United States 2010. Total estimated 2010 was about 129 billion gallons per day (Bgal/d), total 3.5 Bgal/d. In contrast, Department Energy, Energy...
Water consumption at thermoelectric power plants represents a small but substantial share of total water in the U.S. However, currently available data are inconsistent and incomplete, coefficients used to estimate contradictory. The Geological Survey (USGS) has resumed estimation consumption, last done 1995, based on use linked heat budgets complement reported consumption. This report presents methods freshwater study set 1,284 2010 plant characteristics operations data. Power were...
Thermoelectric power generation accounts for over 41% of total U.S. freshwater withdrawals, making understanding the determinants plants' water withdrawals (WW) and consumption (WC) critical reducing sector's reliance on increasingly scarce resources. However, reported data inconsistencies incomplete analysis potential thermoelectric use hinder such understanding. We address these challenges by introducing a novel filtering method more complete assessment determinants. First, we applied...

Abstract Historically, thermoelectric water withdrawal has been estimated by the Energy Information Administration (EIA) and U.S. Geological Survey's (USGS) water‐use compilations. Recently, USGS developed models for estimating at plants to provide estimates independent from plant operator‐reported data. This article compares three federal datasets of withdrawals United States in 2010: one based on compilation, another EIA data, third model‐estimated The data varied widely. Many had...
Thermoelectric (TE) power plants withdraw more water than any other sector of use in the United States and consume at rates can be significant especially waterstressed regions, making it imperative to accurately quantify their usage. Recently, focus has been on improving accuracy availability TE water-use data considering historic sources have inconsistent, incomplete, discrepant. This paper describes benchmarks new software that was developed automate update a physics-based model previously...
