Energy and water are closely connected, and international agencies are taking notice, leading Zerrenner to declare 2014 “the year of the energy-water nexus.” It’s the focus of this year’s World Water Week, hosted by the Stockholm International Water Institute. And in the U.S., the Department of Energy has just issued a 250-page report on the two interdependent resources and will include the topic in its next Quadrennial Review. “In choosing the energy-water nexus as this year’s theme, SIWI and its supporters are affirming—on a global stage—what policy experts have been saying for years: energy and water are inextricably linked, and the best way to set the energy-water system on a sustainable course is to plan for both resources holistically,” Zerrenner writes. “It is no longer possible for each sector to simply talk about the other; they must work together to address the nexus.”
