Barack Obama names Nobel winner Steve Chu as energy secretary
Mr Obama selected Nobel-prize winning physicist Steven Chu as energy secretary and Carol Browner, a confidante of former Vice President Al Gore, to lead a White House council on energy and climate.
Dr Chu, 60, is director of the Lawrence Berkeley National Laboratory in Berkeley, California, and is a leading advocate of reducing greenhouse gases by developing new energy sources.
The selection of Dr Chu, a Chinese American who shared a Nobel Prize for physics in 1997, received widespread praise on Capitol Hill. Senate Majority Leader Harry Reid of Nevada said he looked forward to "confirming Dr.# Chu as quickly as possible."
"His appointment should send a signal to all that my administration will value science. We will make decisions based on the facts, and we understand that facts demand bold action," Mr Obama said.
He made clear he plans take energy policy in a sharply different direction from President George W. Bush, promising aggressive moves to address global warming and support research into alternative energy sources such as wind, solar and biofuels.
