Obama energy pick says will fight global warming

WASHINGTON (Reuters) - Global warming threatens the future and the incoming Obama administration will seek a cap-and-trade system to cut greenhouse gas emissions, Steven Chu, President-elect Barack Obama's pick to be U.S. energy secretary, told lawmakers on Tuesday.

"Climate change is a growing and pressing problem. It is now clear that if we continue on our current path, we run the risk of dramatic, disruptive changes to our climate in the lifetimes of our children and grandchildren," Chu said at his confirmation hearing before the Senate Energy and Natural Resources Committee.

Chu said the administration will push for a cap-and-trade system, which would require power plants, oil refineries and other industrial facilities to buy and sell pollution permits to spew global warming emissions.

"It speaks to the importance he views this area," Chu said of Obama's concerns about global warming.

Chu said he looks forward to working with Carol Browner, who Obama selected as the White House czar to coordinate climate change policy among the various federal agencies and departments. "She has a difficult task ahead of her," he said.

Sen. Jeff Bingaman, who heads the Senate panel, said he hopes the committee will approve Chu's nomination this week, with confirmation by the full Senate next Tuesday.

Chu said he will work quickly to implement those parts of Obama's planned economic stimulus plan that relate to energy, though he did not provide any details.

"Economic stimulus means we have to move fast," Chu said.

He said the United States faces "immediate threats" because of dependence on oil.

"We must make a greater, more committed push toward energy independence and with it a more secure energy system," he said.

Chu reiterated Obama's comments that the administration would be willing to consider expanded offshore drilling as part of a comprehensive energy policy. But he noted that the United States has only 2 percent of the world's oil reserves and accounts for just 5 percent of global oil production.
