The Dept. of Energy provides important science research support through its national labs, grants for university researchers, and support of public-private partnerships. It’s important to fund DOE and provide structure to its initiatives in order to maintain American scientific innovation.
Much of the energy research done by the Dept. of Energy could be done by the private sector without expense to taxpayers, so there’s need for it to be done by the DOE. The agency should be eliminated altogether and its funding re-allocated.
