Chu, who will be the first Nobel Prize winner to be appointed to the US cabinet, is the director of the Lawrence Berkeley National Laboratory and has played a key role in moving the lab in the direction of specializing in renewable energy, particularly in the field of new fuels for transportation. LBNL is experimenting with making biofuels from different types of biomass, using algae in fermentation tanks to make fuel, and applying solar energy to convert water and carbon dioxide to fuels. "[President-elect Obama] certainly needs somebody who can focus on the science and energy policies and I can't think of a better guy than Steve," says Mike Lubell from the American Physical Society.
Originally his father wanted him to be an architect as "the competition in physics was too strong." Chu did both his graduate and postdoctoral research at UC Berkeley. He then spent nine years at Bell Labs before joining Stanford University's physics department where he remained between 1987-2004. He shared the 1997 Nobel Prize with Claude Cohen-Tannoudji and William Phillips for cooling and trapping atoms with lasers.
During the presidential campaign, Obama said he would invest $150 billion over 10 years in clean energy and proposed requiring that 10 percent of electricity in the United States comes from renewable sources by 2012. Chu, has been one of the most public faces of promoting renewable energy. At the National Clean Energy Summit held in August, Chu said "I think political will is absolutely necessary. But we need new technologies."
Chu is also one of the co-authors of the 2006 National Academy of Sciences' report Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future , in which he lobbied for the creation of the Advanced Research Projects Agency-Energy (ARPA-E) at the Department of Energy as a way of funding risky hich-tech technologies to solve the US energy crisis. ARPA-E, although legislation creating its existence has passed into law, has yet to be receive a budget as the proposal is not supported by the Bush administration. Chu's appointment increases the likelihood that the ARPA-E will finally be created.
The largest part of the Department of Energy's budget however, goes towards maintaining the nuclear weapons stockpile. It is too early to say what the implications are for Chu's appointment to the long term future of the three main nuclear weapons labs at Lawrence Livermore, Los Alamos, and Sandia. According to the Wall Street Journal, Chu is likely to focus his attention on the Energy Department's core missions: basic science, nuclear weapons and cleaning up a nuclear-weapons manufacturing complex contaminated since the Cold War.
