US President-elect Barack Obama, who has promised a pro-active approach to the environment and global warming, has named his Energy Secretary. Nobel physics laureate Steven Chu, who won the 1997 Nobel Prize and now directs the government’s Lawrence Berkeley National Laboratory in California, will head the energy department.“Some say we have to concentrate exclusively on restablishing the health of the economy,” said Chu. “I look forward to being part of the president-elect’s team which believes that we must repair the economy and put us on a path forwards, towards sustainable energy.” Obama’s energy and environmental team will play a crucial role in his quest to revive the US economy. The president-elect hopes that addressing climate change can produce the jobs that will help pull the US economy out of a deepening recession. His transition team has already begun to draw up a blueprint for a massive recovery plan to stimulate the economy and create about 2.5 million jobs, some of them so-called green jobs.
