Notes: The values listed here may vary from other listings due to rescissions, uncosted obligations, inclusion or exclusion of other budget lines, and other factors. The efficiency line listed here does not include state and local grants, or the Federal Energy Management Program. The nuclear fission line includes only direct civilian energy-related R&D and University training support. The fossil energy line does not include expenditures for the clean coal program, which is a demonstration rather than a research and development effort.
