; and (B) investments in targeted technology research that offer the greatest potential for positive impact; (2) innovative technology advances that address the challenges relating to the energy-water nexus; and (3) the Department of Energy’s Energy-Water Nexus Crosscut Team and its mission. (c) Definition of energy-Water nexus In this Act, the term energy-water nexus means the links between energy and water systems, including— (1) the water needed to produce fuels, generate electricity, and produce other forms of energy; (2) the energy needed to transport, reclaim, treat, and reuse— (A) water, including water needed for heating and cooling; and (B) wastewater, including produced waters; (3) the energy available in organic wastewaters and wet waste streams, including municipal and industrial wastewaters and livestock manures; and (4) the waste heat available in industrial process and cooling water discharges, steam system condensate and cooling water, and thermoelectric cooling water discharges. 1112. National energy-water nexus database (a) Establishment Not later than 4 years after the date of enactment of this Act, the Secretary of Energy shall establish and maintain an energy-water nexus database. (b) Purposes The purposes of the database are— (1) to advance the availability, timely distribution, and widespread use of data and information relating to the energy-water nexus for energy and water management, education, research, assessment, and monitoring purposes; (2) to advance understanding of interactions between energy and water systems through access to data, including models and modeling results; (3) to promote data collection and information management with respect to— (A) the uses, characteristics, and ultimate fate of water used for or produced in oil and gas production, including safe and appropriate reuse of these non-traditional waters; (B) water consumption based on metered data; and (C) energy use in water systems
