As of April 22, Steven Chu has served his last day at the Department of Energy (DOE) as its secretary. Chu will return to his post as a professor at Stanford University in California.
Chu is the longest-serving secretary in DOE history, according to reports.
Currently heading up the DOE is Deputy Energy Secretary Daniel Poneman, who is now its acting secretary. Ernest Moniz, President Barack Obama's selection to head the DOE on a permanent basis, is in the midst of the confirmation process in the Senate.
Moniz, according to reports, will likely be confirmed before the full Senate. The Senate's Energy and Natural Resources Committee confirmed the Massachusetts Institute of Technology physicist in a nearly unanimous vote of 21-1.
