In an October 19 interview, Senator Lisa Murkowski (R-AK), ranking Republican on the Senate Energy and Natural Resources Committee, defended the Department of Energy's loan guarantee program, as some members of Congress have attacked the program. Murkowski still sees “an appropriate role” for government financing in the realm of clean technology research, development, and deployment. Senate Energy Chairman Jeff Bingaman (D-NM), together with Murkowski, is planning a hearing this November on investment in clean energy technologies.
