Solar Powering Your Community: A Guide for Local Governments
(As demand for energy increases, many communities are seek...)
As demand for energy increases, many communities are seeking ways to meet this demand with clean, safe, reliable energy from renewable sources such as sun and wind. Fortunately, many of the key technologies that can unlock the power of these renewable resources are available on the market today. While the United States Department of Energy (DOE) continues to fund research and development (R&D) to improve solar technologies, DOE is also focusing on accelerating a robust nationwide market for the currently available technologies. The development of a nationwide market requires overcoming barriers to the widespread adoption of solar energy technologies. These barriers include complicated procedures for permitting and connecting systems to the grid, financing challenges, a lack of awareness of solar energy solutions among key decision-makers, and a lack of trained installation contractors. Local governments are uniquely positioned to remove many of these barriers, clearing the way for solar markets to thrive in their locales. Representatives of local governments who understand and prepare for policy and market changes can optimally position their communities in the emerging renewable energy economy.
Steven Chu is an American physicist who was awarded the 1997 Nobel Prize for Physics for their independent pioneering research in cooling and trapping atoms using laser light. He is the former director of the Lawrence Berkeley National Lab, a professor of physics, molecular and cellular biology. Steven Chu also served as the Secretary of Energy from 2009 to 2013.
Background
Stephen Chu was born on February 28, 1948, in St. Louis, Missouri, into an academic family of Chinese heritage. His father, Ju Chin Chu, came to the United States in 1943 to continue his education at the Massachusetts Institute of Technology in chemical engineering, and two years later, Steven's mother, Ching Chen Li, joined him to study economics. When they married in 1945, China was in turmoil, and the possibility of returning grew increasingly remote, and they decided to begin their family in the United States.
Steven and his siblings were born as part of a typical nomadic academic career: his older brother was born in 1946 while Ju Chin Chu was finishing at MIT, Steven was born in St. Louis in 1948 while Ju Chin Chu taught at Washington University, and Steven's younger brother was born in Queens shortly after Ju Chin Chu took a position as a professor at the Brooklyn Polytechnic Institute.
Education
Steven graduated from Garden City High School. He received a Bachelor of Arts in mathematics and a Bachelor of Science in physics at the University of Rochester in 1970, and a Doctor of Philosophy in physics from the University of California, Berkeley in 1976.
Chu received an honorary doctorate from Boston University when he was the keynote speaker at the 2007 commencement exercises.
After receiving his doctorate, Steven Chu remained at the University of California for two years as a postdoctoral researcher before joining Bell Labs. He joined the staff at Bell Laboratories in 1978 and became the head of the quantum electronics research department at AT&T Bell Laboratories in 1983.
He left Bell Labs and became a professor of physics at Stanford University in 1987, serving as the chair of its Physics Department from 1990 to 1993 and from 1999 to 2001.
In 1997 he received Nobel Prize in Physics with Claude Cohen-Tannoudji and William D. Phillips "for development of methods to cool and trap atoms with laser light."
In 2004 Chu returned to Berkeley as director of the Lawrence Berkeley National Laboratory, an institution with a long history of research in atomic and nuclear physics that is now part of the system of national laboratories supported by the United States Department of Energy. There he encouraged research into renewable energy, particularly the use of solar energy to create biofuels and generate electricity.
In December 2008 Chu was selected by President-elect Barack Obama to serve as secretary of energy, partly on the basis of his administrative experience and scientific credentials and partly because of his commitment to using science to develop alternative energies and combat climate change. Chu was confirmed by the United States Senate in a unanimous voice vote on January 20, 2009. Under Chu's leadership, the energy department took a central role in implementing funding for renewable energies as part of the president’s large economic stimulus bill passed in February 2009, attempting to redirect the country’s energy consumption away from traditional fossil fuels. As the first scientist to hold a Cabinet position and the longest-serving Energy Secretary, he recruited outstanding scientists and engineers into the Department of Energy. He began several initiatives including ARPA-E (Advanced Research Projects Agency-Energy), the Energy Innovation Hubs, and was personally tasked by President Obama to assist BP in stopping the Deepwater Horizon oil leak. Chu stepped down as secretary of energy in April 2013.
After his government service, Chu has returned to Stanford to become a Professor of Physics and Professor of Molecular and Cellular Physiology, where he will teach and continue his research in biophysics, biomedicine, energy, and energy economics.
In addition to his continuing work marshaling scientists and resources to address the energy and climate change challenges, he has begun a new research program synthesizing and applying new nanoparticle probes for biology and biomedical research. He is also working on new approaches to lithium-ion batteries, PM2.5 air filtration and other applications of nanotechnology and electrochemistry.
Chu is on the board of directors of Xyleco, a company developing alternate energy.
In 1985 Chu and his coworkers at Bell Labs used an array of intersecting laser beams to create an effect they called "optical molasses," in which the speed of target atoms was reduced from about 4,000 km per hour to about 1 km per hour as if the atoms were moving through thick molasses. The temperature of the slowed atoms approached absolute zero (−273.15 °C, or −459.67 °F). Chu and his colleagues also developed an atomic trap using lasers and magnetic coils that enabled them to capture and study the chilled atoms. Phillips and Cohen-Tannoudji expanded on Chu's work, devising ways to use lasers to trap atoms at temperatures even closer to absolute zero. These techniques make it possible for scientists to improve the accuracy of atomic clocks used in space navigation, to construct atomic interferometers that can precisely measure gravitational forces, and to design atomic lasers that can be used to manipulate electronic circuits at an extremely fine scale.
Steven Chu is a vocal advocate and openly expresses his support for more research efforts for the use of nuclear power and renewable energy. He became a member of the Copenhagen Climate Council, created to build momentum for the United Nations Climate Change Conference held in Copenhagen in 2009. He believes that by shifting away from using fossil fuels, the negative effects of climate change as well as global warming can be battled.
He is also known for advocating the roofs of buildings and roads have white or light colors, in order to reflect more sunlight back to space to help mitigate the effects of global warming.
Quotations:
"The atoms become like a moth, seeking out the region of higher laser intensity."
''Science is really about describing the way the universe works in one aspect or another in all branches of science-how a life-form works, how this works, how that works. ... You have to have a natural curiosity for that.''
"Somehow we have to figure out how to boost the price of gasoline to the levels in Europe."
"So imagine a world 6 degrees warmer. It's not going to recognize geographical boundaries. It's not going to recognize anything. So agriculture regions today will be wiped out."
"The atoms become like a moth, seeking out the region of higher laser intensity."
"Sustainable energy is the equivalent of the U.S. moon shot."
"Just refrigerator efficiency saves more energy than all that we're generating from renewables, excluding hydroelectric power... I cannot impress upon you how important energy efficiency is. It doesn't mean you eat lukewarm food and your beers are lukewarm. You can still have it; you just make a better thing."
"If I were emperor of the world, I would put the pedal to the floor on energy efficiency and conservation for the next decade."
"I approached the bulk of my schoolwork as a chore rather than an intellectual adventure. The tedium was relieved by a few courses that seem to be qualitatively different. Geometry was the first exciting course I remember. Instead of memorizing facts, we were asked to think in clear, logical steps. Beginning from a few intuitive postulates, far-reaching consequences could be derived, and I took immediately to the sport of proving theorems."
Membership
Steven Chu is a member of numerous honorific societies including the National Academy of Sciences, the American Philosophical Society, the Royal Academy of Engineering, the Academia Sinica, the Korean Academy of Sciences and Technology, and is an honorary member of the Institute of Physics, the Chinese Academy of Sciences, and a Lifetime Member of the Optical Society of America.
In 1997, Steven married Jean Chu, who holds a Doctor of Philosophy in Physics from Oxford and has served as chief of staff to two Stanford University presidents as well as Dean of Admissions. He has two sons, Geoffrey and Michael, from a previous marriage to Lisa Chu-Thielbar.
