The National Energy Technology Laboratory (NETL) is a leader in evaluating the relationship between water and energy. The Environmental Water Resources program and Geological Sciences Division at NETL have evaluated the impact of energy development on water quality and availability and pioneered means of decreasing water consumption and resource impairment. To date, NETL?s research has focused on evaluating water use and consumption in thermoelectric power plants, quantifying legacy acid mine drainage, advancing water management options for resource extraction, and developing creative solutions to remediate water quality leading the way with research to support the National Laboratories Energy-Water Nexus Roadmap to Congress. This activity involves all the national laboratories in the development of a research and development plan for technologies and methodologies that reduce the impact of energy development on water and water demands in energy production. NETL has a portfolio of innovative technologies, expertise, and knowledge to continue minimizing the impact of fossil energy use on water quality and availability and ensure the success of the Energy-Water Nexus.
