The Department of Energy, function by function and account by account.

DOE's appropriations read two ways. First by budget function — the national-defense (050) groups (NNSA, Environmental & Other Defense Activities, Nuclear Energy-050) kept strictly apart from the civilian science (250) and energy (270) functions. Then by appropriation account, every line tagged with its function. FY2025 enacted, FY2026 enacted, and the FY2027 request, $ in thousands. Both dimensions tie to the same grand total to the dollar.

National defense · budget function 050 ($ in thousands)

The atomic-energy-defense remainder of the national-defense topline — the same function as the Department of War. NNSA is the nuclear-weapons enterprise; this is roughly half the department.

The non-defense budget — a different function entirely: the Office of Science (function 250) and the applied-energy programs (function 270).

By appropriation account, department-wide ($ in thousands)

Every appropriation/offset line, grouped by its budget function — the second dimension that reconciles, line for line, to the same grand total.

Both dimensions — by function and by appropriation account — are asserted equal to the same grand total at build time, per fiscal year. The mandatory P.L. 119-21 (Working Families Tax Cut Act) Reconciliation resources are kept as a separate line and never folded into this discretionary request.
