13% of U.S.’s Energy Goes to Collect, Prepare Water: Study

Energy used for treating, heating, pumping and cooling water in the U.S. accounted for almost 13 percent of the nation’s total annual consumption, according to a University of Texas at Austin study.

The amount, about 12.3 quadrillion BTUs, is equivalent to the annual energy usage of about 40 million Americans, the study published in the journal Environmental Research Letters showed. That makes water one of the largest energy consumers in the U.S., according to the study’s authors, Kelly Twomey Sanders and Michael Webber.
