A new report by the Pacific Institute demonstrates that water use in the United States declined in the five-year period ending in 2010. The nation saw reductions in all sectors, including agriculture; municipal and industrial; and thermoelectric power. The report reveals that nearly two-thirds of the reductions were in the thermoelectric power sector, the largest use of fresh and saline water in the United States. These water-use trends reveal overall improvements in the management of our nation's water. Although substantial progress has been made, current water use trends are not sustainable in the face of population growth and climate change.
