The first publication of the Energy-Water initiative, introduces the energy-water nexus, examines the water requirements of power generation and outlines some potential technical and institutional solutions for improving the management of the nexus.
Today, more than 780 million people lack access to potable water, and over 1.3 billion people lack access to electricity. At the same time, estimates show that by 2035, global energy consumption will increase by 35%, while water consumption by the energy sector will increase by 85%. Climate change will further challenge water and energy management by causing more water variability and intensified weather events, such as severe floods and droughts.
To support countries’ efforts to address challenges in energy and water management proactively, the World Bank has embarked on a global initiative: thirsty energy. Thirsty Energy aims to help governments prepare for an uncertain future, and break disciplinary silos that prevent cross-sectoral planning. With the energy sector as an entry point, thirsty energy quantifies tradeoffs and identi­fies synergies between water and energy resource management.

Thirsty energy demonstrates the importance of combined energy and water management approaches through demand-based work in several countries, thus providing examples of how evidence-based operational tools in resource management can enhance sustainable development.
