New Technologies and Approaches Needed to Shore Up Interconnected U.S. Energy and Water Systems, Says New Report

To strengthen the reliability and resiliency of the nation’s energy and water systems, the U.S. Department of Energy should develop innovative technology and infrastructure at the intersection of the two systems through a suite of pilot programs, says a new report from the National Academies of Sciences, Engineering, and Medicine. U.S. energy and water systems are profoundly interconnected, and disruptions can cascade rapidly across both, affecting public health, economic activity, environmental quality, and national security.
Energy and water systems are often managed separately, however, and regional environmental, socioeconomic, and political conditions can vary widely, making a single national approach inadequate for addressing the range of challenges facing the systems. For example, data centers are placing new and increasing strain on the electric grid and using significant quantities of water in some areas, while other stressors such as extreme weather are testing aging infrastructure and exposing systemic vulnerabilities. The report points to Winter Storm Uri in 2021 when prolonged power outages disrupted water treatment and distribution across Texas, underscoring how coupled energy and water systems are.
“The breadth of challenges and contexts across the energy-water nexus are extraordinary and will take a multipronged approach to address,” said Katharine Jacobs, chair of the committee that wrote the report and director of the Center for Climate Adaptation Science and Solutions and professor of environmental science at the University of Arizona. “Our report offers a foundation for DOE to integrate cross-sector collaboration and regional knowledge to protect and strengthen our communities and country.”
Pilot programs could demonstrate technologies that advance resilience and reduce structural risks to energy and water systems, the report says, and allow DOE to facilitate the deployment of integrated energy-water technologies that are attuned to local needs and constraints. In addition, pilot programs could offer a platform to improve access to energy and clean water, as well as create skilled jobs in the energy sector. The report provides strategies and considerations for how to build a suite of pilot projects and ensure that investments yield measurable, long-term benefits and effectively mitigate risk.
