President-elect Barack Obama on Monday named an environmental and energy team that he said signaled his determination to tackle global warming quickly and develop alternative forms of energy. He vowed to "move beyond our oil addiction and create a new hybrid economy." 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. Browner headed the Environmental Protection Agency in the Clinton administration. Chu 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. "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," Obama said.
