Discussions of energy often bring to mind giant structures, such as coal and gas plants, wind towers and arrays of solar cells. Yet even enormous coal-fired plants rely on nanoscale combustion of carbon-containing molecules to produce power. Nanoscience provides a powerful way to measure, analyze and improve the efficiency of many of these processes. Catalysts made from metal-organic frameworks, nanostructured lattices of metal and organic molecules, improve efficiency and reduce unwanted byproducts in refineries as well as chemical plants. They can also be used to capture carbon emissions from power plants. Nanoscience is plays a critical role of many green power sources. Scientists have shown they can improve solar cell efficiency with quantum dots and nanostructured semiconductors. Nanoscale engineering has enabled researchers to build batteries that last longer, recharge faster and hold more power. Such batteries could power electric cars or store renewable energy on the electrical grid. Several teams have demonstrated synthetic plants that use sunlight to produce chemicals and some types of fuel directly from sunlight and carbon dioxide. This technology produces liquid fuels that utilities could store for months or years at a time. Ultimately, synthetic plants could recycle the same carbon dioxide produced by liquid fuel combustion, creating a fully carbon neutral system.

Solar Power: Is It Time for the Big Push?

Jan 23, 2013

Solar power seems poised for a breakthrough. Over the past four years, prices for solar panels declined 75 percent. Recently, four experts discuss how we move solar technology from the lab to commercial reality.

Charging Up the Auto Industry

Jan 27, 2012

The 2006 documentary “Who Killed the Electric Car," suggested that electric cars would forever be just around the corner, never fully arriving in the U.S. market. But electric and hybrid vehicles are now available from a slew of major car manufacturers. 

The Future of Computing, from Extreme to Green

Aug 18, 2010

In September, 2010, leading scientists across several disciplines will gather for the next Kavli Futures Symposium to discuss what science needs from computing. In advance of this meeting, four of the participants discuss those needs, how current computing advances are impacting research, and how the future of computing is not only looking extreme and green, but is moving closer to how the brain computes.
