Berkeley Lab project in India to measure impact of pollution on cool roofs
With the aid of rooftop instruments, satellite images, an airplane and a balloon, Berkeley Lab scientists are conducting the first-ever study to determine how pollution impacts the efficacy of white roofs in cooling the planet. The yearlong project in northern India will also be the first to take physical measurements to characterize the cooling and climate effects of white roofs.

Simulating turbulent combustion speeds design of power and propulsion devices
A team led by mechanical engineers Joseph Oefelein and Jacqueline Chen of Sandia National Laboratories simulates turbulent combustion at different scales. Chen and Oefelein were allocated 113 million hours on Oak Ridge Leadership Computing Facility's Jaguar supercomputer in 2008, 2009 and 2010 to simulate autoignition and injection processes with alternative fuels. For 2011 they received 60 million processor hours for high-fidelity simulations of combustion in advanced engines.

Supercomputers and airplanes help model hurricane structure and intensity
Information from major hurricanes such as Katrina is being put to good use by scientists striving to understand how hurricanes intensify. A research team led by Jon Reisner of Los Alamos National Laboratory is employing the Oak Ridge Leadership Computing Facility's Jaguar supercomputer to use data from lightning detectors and even wind instruments mounted on planes flown into the eye of a hurricane to improve atmospheric models. These simulations may lead to more accurate prediction of hurricane intensities.

Buried treasure
EMSL scientist Hongfei Wang and his team recently struck a vein that could lead to research gold for scientists interested in molecular interactions at interfaces. Their picosecond-femtosecond broadband sum frequency generation system is now ready to provide a new generation of surface vibrational spectroscopy and imaging.

Chemistry and materials simulations speed clean energy production and storage
Catalysts are just one area of investigation for a multi-institutional team whose 70 publications in 3 years detail prodigious scientific output from the world's fastest chemistry simulations. "Our long-term goal is enabling the design of new generations of clean and sustainable technologies to produce, transmit, and store energy," said team leader Robert Harrison, a computational chemist at Oak Ridge National Laboratory.

Berkeley Lab scientist walks the walk -- produces more electricity than he consumes
Energy management engineer Steve Greenberg bikes three miles uphill to work every day, rain or shine. He refuses to use a desktop computer, insisting on a less energy-intensive laptop. And to avoid using paper towels each time he visits the bathroom, he keeps a hand towel in his office. Those are only a few of the things he does to reduce his carbon footprint—and that's just at work.

NETL's green projects promise energy efficiency all year round
Forty years after the first Earth Day, it is almost second nature to toss a can or plastic bottle into the recycling bin, but being green is about much more than reusing materials. Just as individuals make a personal decision to "reduce, reuse, and recycle," businesses, industry, and other organizations are making the same commitment to being green.

Conference tackles interstate transmission
The US electricity grid is strained to its limit, and the nation's windiest and sunniest places are rarely near cities that generate high demand. Finding ways to string new power lines across several states is a challenge for even the most creative regulators and energy analysts determined to increase America's use of renewable energy.

Both directions at once
The challenge of controlling climate change is a goal that, to many, appears to be at odds with the equally important goal of energy security. However, the idea that the two goals are somehow mutually exclusive is not one accepted by ORNL energy researcher David Greene. "We don't want to sacrifice one for the other," he says. "We want -- and we believe it possible -- to achieve environmental goals and energy security goals at the same time.

DOE technology monitors CO2 injection in Australian gas field
Australia has launched the first carbon sequestration project in the southern hemisphere with the help of technology developed by researchers at the US Department of Energy. The Otway Basin Pilot Project will inject and monitor carbon dioxide in a depleted gas field in southeastern Australia to demonstrate the feasibility of storing the greenhouse gas in the Waarre Formation of the Otway Basin, and similar formations worldwide, to fight global climate change.

On thin icege/gi
Thin clouds high in the upper troposphere, like cirrus clouds, may have a significant influence on Earth's climate and enhance the "greenhouse effect" by absorbing more of the sun's radiation than they take in. Unknown is how ice crystals in these clouds absorb and reflect radiant energy and enhance the amount of radiant energy emitted toward the earth's surface.
