BES Energy Security Plan Workshop: October 21-25, 2002 Report: March 2003 Considering the urgency of the energy problem, the magnitude of the needed scientific breakthroughs, and the historic rate of scientific discovery, current efforts will likely be too little, too late. Accordingly, BESAC believes that a new national energy research program is essential and must be initiated with the intensity and commitment of the Manhattan Project, and sustained until this problem is solved. Follow-on focused workshops seek to define the basic research needed to overcome both short-term technology showstoppers and long-term scientific grand challenges.

Sunlight is a compelling solution to our need for clean, abundant sources of energy in the future. Huge gap between our present use of solar energy and its enormous undeveloped potential defines a grand challenge in energy research. Much of the researchers optimism is based on the continuing, rapid worldwide progress in nanoscience and molecular biology. Powerful new methods of nanoscale fabrication, characterization, and simulation - using tools that were not available as little as five years ago - create new opportunities for understanding and manipulating the molecular and electronic pathways of solar energy conversion. Additional optimism arises from impressive strides in molecular biology that will soon bring the secrets of photosynthesis and natural bio-catalysis into sharp focus. http://www.sc.doe.gov/bes/reports/files/SEU_rpt.pdf Basic Research Needs for Superconductivity Workshop Research for a Secure Energy Future Supply, Distribution, Consumption, and Carbon Management Decision Science and Complex Systems Science Carbon Energy Sources Carbon Management No-net-carbon Energy Sources Distribution/ Storage Energy Consumption Energy Conservation, Energy Efficiency, and Environmental Stewardship Coal Petroleum
