A number of legislative proposals to restructure or eliminate the Department of Energy (DOE) and the DOE laboratories have been introduced since the end of the Cold War, especially since the beginning of the 104th Congress. This legislation has been introduced because of perceived major problems with DOE, including its overall mission. Sponsors state, for example, that about 85% of DOE's budget is for non-energy programs, even though the nation's dependency on foreign energy sources has increased since the establishment of the department. Also of concern is the department's failure to go far enough, in their view, in solving its long-term management problems, downsizing, and reducing budgets.
