Water and energy are interconnected in many ways. Electricity generation requires substantial amounts of water, and pumping and treating water requires electricity. Within the context of efficiency, this water and energy nexus is perhaps most easily understood by the principle that every drop of water saved in the U.S. conserves energy, and every unit of energy saved conserves water. But, despite this clear link, efforts to improve efficient water and energy use have traditionally been handled separately. However, as we will hear today, there is substantial evidence to show that there is a need to unify these efforts into a more collaborative and comprehensive framework.
