Annual Energy Outlook

Published by U.S. Energy Information Administration | Department of Energy | Metadata Last Checked: August 03, 2025 | Last Modified: 2019-01-24
The Annual Energy Outlook presents longterm annual projections of energy supply, demand, and prices focused on the U.S. through 2050, based on results from EIA's National Energy Modeling System (NEMS). NEMS enables EIA to make projections under alternative, internally-consistent sets of assumptions, the results of which are presented as cases. The analysis in AEO2014 focuses on five primary cases: a Reference case, Low and High Economic Growth cases, and Low and High Oil Price cases.
