Energy discretionary budget authority
From the OMB Public Budget Database — clean, summable, and the figure to cite for an agency total. It is the whole of Energy's discretionary request, not a total of the parsed lines above, and this page never adds the two together.
What this funds
Explores the fundamental constituents of matter and energy and the forces governing them, supporting particle physics research and operating major accelerator and detector facilities to keep the U.S. at the forefront of discovery science.
Extracted from Energy Programs, p. 17. Verbatim; nothing here is paraphrased.
