The U.S. Geological Survey released a comprehensive resource assessment detailing energy reserves on public lands. The assessment reveals that coal deposits beneath federally managed public lands contain sufficient energy to power the United States for 600 years at current consumption rates. The published survey documents 4.2 billion short tons of coal reserves that link directly to active mining operations.
The agency also identified an additional 356 billion short tons of available coal resources sitting in undisturbed geological formations across the conterminous United States. Federal officials compiled data across multiple government jurisdictions to measure total resource availability. This survey establishes a scientific baseline for energy planning and land management activities.
The Department of the Interior published these findings to clarify energy reserves across public domain properties. Researchers evaluated resource depth, seam thickness, and extraction accessibility during the analysis. The study combines geological mapping data with active mining production figures.

Key Players and Stakeholders
Secretary of the Interior Doug Burgum announced the report findings on behalf of the federal administration. President Donald Trump signed Executive Order 14261, which ordered the initial review of federal coal resources. Secretary Burgum stated: “American Energy Dominance is more important than ever, and so is beautiful clean coal’s role in the production of electricity needed to fuel our future prosperity”.
Secretary Burgum added: “Thanks to the USGS’s rigorous and independent assessment, we’re better equipped to manage America’s vast public lands responsibly while supporting energy security and economic opportunity”. Multiple federal agencies maintain oversight of the relevant public lands, including the Department of Agriculture, Department of Defense, Department of Energy, Department of the Interior, and the Tennessee Valley Authority. Scientists from the U.S. Geological Survey conducted the physical mapping and data aggregation work.

Geographic Breakdown
The mapped resources lie beneath federal public lands across the conterminous United States and Alaska. Western states hold the primary concentration of federal coal deposits west of the Mississippi River. Wyoming contains the highest density of federal coal operations in the nation.
Wyoming hosts 14 federal coal mines, representing 87 percent of all reported reserves tied to active federal leases. The Powder River Basin in Wyoming holds 180.9 billion short tons of available subbituminous coal, representing 50.75 percent of all available federal coal resources in the lower 48 states. The North Antelope Rochelle mine in the Powder River Basin contains 1.3 billion short tons of reported reserves, operating as the largest coal mine globally.
Other western states maintain active federal coal leases, including Colorado with six mines, North Dakota with four mines, and Utah with four mines. Montana hosts three active federal mines, while Alabama contains three active federal metallurgical coal mines. In Alaska, the USGS estimates at least 140 billion short tons of available resources, with potential total resources reaching 5.5 trillion short tons.
