In its 2001 performance and accountability report on the U.S. Department of Energy (DOE), GAO identified important issues facing the department as it works to carry out its multiple, complex, and highly diverse missions. The information GAO presents in this report is intended to help to sustain congressional attention on these challenges and a departmental focus on continuing to make progress in addressing these challenges and ultimately overcoming them. The report should help improve government for the benefit of the American public. This report is part of a special series of governmentwide and agency specific issues.
