DOE STAFF CHANGE OVER TIME

The White House Requested a slight increase in overall staff across DOE’s science and energy innovation offices in FY27

FTE levels at DOE’s science and energy innovation offices, FY25 – FY27

FY25 numbers are confirmed; FY26 numbers are estimates; FY27 numbers are requested staff

Note: The EFI Foundation’s analysis focuses exclusively on DOE’s science and energy innovation offices, unless noted otherwise. See our methodology for a full list of offices tracked. “FTE” is used throughout to mean full-time equivalents for federal employees, as measured by the Office of Management and Budget (OMB). Data are from OMB’s Presidential Budget Request Technical Supplement for fiscal year 2027.

The White House Proposed Steep Staffing Cuts Even for Offices Supporting Its Technology Priorities

In many cases, these offices’ staffing levels are projected to be smaller than they were in the first Trump administration, despite the fact that U.S. Department of Energy (DOE) budgetary resources and responsibilities have grown.

Staff Reductions Save Little While Increasing Workloads

  • Staff salaries and benefits comprise 2% of DOE’s overall spending on science and energy innovation.

  • Proposed staff reductions represent a 33% increase in amount of funding to be deployed per FTE.

Note: “Object classes” are categories defined by OMB that indicate the purpose of government spending, such as salaries, grants, etc. “Federal employees” encompasses object classes 11 and 12: “Compensation” and “Benefits”.

Staff Reductions in 2025 Mark the Largest in Recent History

DOE’s unprecedented workforce cuts may have played a role in the department’s limited spending last year.

About This Data Set

Transparent data and unbiased analysis of DOE staffing, budgeting, and contracting needs are crucial. EFIF is assembling relevant data from hundreds of federal government reports to provide new insights into how people impact progress in innovation.

This data and analysis focuses on DOE’s energy and science innovation programs, examining DOE workforce trends, staffing levels, skill sets, and how contractors are used to execute the mission.
