National Energy Modeling System (NEMS)

The National Energy Modeling System (NEMS) is a computer-based tool used to forecast and analyze the future of the U.S. energy market. It evaluates factors like energy supply, demand, prices, and policies to help policymakers understand potential impacts. NEMS considers various energy sources—such as oil, gas, coal, renewables—and how they interact over time. By simulating different scenarios, it helps inform decisions on energy development, environmental effects, and economic outcomes, ensuring comprehensive planning and policymaking for the nation's energy future.
