A solution to the global energy problem will require revolutionary new technology, as well as conservation and evolutionary improvements in existing technologies. Efficiencies in the use of energy will come from many advances, but particularly from revolutionary new materials that are inexpensive, environmentally safe, and both stronger and lighter than steel. Transmission and storage of energy, particularly electrical power and hydrogen, is a major societal need, and holds the most promise in solutions with new nanotechnologies. It is in this area that we believe nanoscience can bring the most immediate benefits, with nanotubing and other nano-based materials creating new opportunities to transport electricity efficiently and at lower cost over very long distances.
The most dramatic, real and concrete long term benefit in energy research would be if the U.S. science community could deliver a breakthrough fuel system that could both allow society to avoid reliance on volatile Middle East oil supply while at the same time avoiding harmful emissions or other environmental impacts during the energy conversion process. Perhaps the greatest challenge, but most dynamic change toward these goals, would be if nanoscience could render the widespread collection, conversion and transmission of solar energy viable and affordable.
