10-Dec-2010 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.
21-Sep-2010 As Auto X reaches the finish line, a new race begins
After two years of intense competition, the winners of the Automotive X Prize were announced during a ceremony at the Historical Society of Washington, D.C. on Sept. 16, 2010. Deputy Secretary Daniel Poneman spoke at the ceremony, praising the competition as an example of "the power of innovation and ingenuity to achieve transformative breakthroughs."
13-Jul-2010 Ethanol-fueled racecar engines outpower lead-fueled engines
A group of automotive researchers from the US Department of Energy's Argonne National Laboratory and industry have shown that a fuel-injected racing car engine fueled by E-85, an ethanol-based fuel, outperforms the same engine with a carburetor and leaded racing fuel.
17-May-2010 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.
22-Apr-2010 NREL finds a way to give LEDs the green light
Light bulbs that last 100 years and fill rooms with brilliant ambiance may become a reality sooner rather than later, thanks to a National Renewable Energy Laboratory discovery.
6-Jan-2010 Argonne advanced battery research driving to displace gasoline
In excess of seven million barrels of gasoline are consumed by vehicles in the United States every day. As scientists race to find environmentally sound solutions to fuel the world's ever-growing transportation needs, battery researchers are exploring the promise of lithium-air battery technology.
6-Oct-2009 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.
16-Sep-2009 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.
3-Aug-2009 Award-winning reflector to cut solar cost
In a breakthrough development that recently netted a coveted R&D Magazine top 100 award, a small solar company has teamed with scientists at NREL to develop massive curved sheets of metal that have the potential to be 30 percent less expensive than today's best collectors of concentrated solar power.
13-May-2009 A wealth of liquid fuel right under our feet
INL has partnered with Baard Energy to design one of the nation's first coal-to-liquids plants, a project that could help power the US transportation system without relying on foreign oil.
22-Apr-2009 NREL gearbox study aims to grease wind power's future
Wind turbines are designed to last 20 years. But gearboxes and other key components are wearing out sooner. Engineers at NREL's National Wind Technology Center are working with industry to discover why and retool the design process to improve reliability, reduce the cost and help the nation reach its clean energy potential.
17-Mar-2009 Controlling heat key to hybrid performance
Advanced hybrid-electric vehicles are poised to transform the auto market. But excess heat can sap hybrids' advantages. Researchers in NREL's Advanced Electronics Laboratory are exploring every layer of hybrid technology to reduce heat and dramatically improve performance and efficiency while reducing costs.
24-Feb-2009 How 10 trillion bits per square inch assemble themselves perfectly
Two chemically different polymers linked together to form self-assembling block copolymers can have the potential to vastly improve the properties and manufacturing processes of nanostructured materials. Using crystal structures as a template, researchers at Berkeley Lab and the University of Massachusetts Amherst have created perfect arrays of nanoscopic block-copolymer domains, packing 10 trillion bits to the square inch and extending over several square centimeters.
5-Feb-2009 The secrets of Darwin's dinobird
For centuries, the field of archaeology has depended on what's visible to the naked eye. Now, researchers are revealing what lies beneath the surface of a key evolutionary fossil, Darwin's "dinobird."
9-Jul-2008 Powering the cars of the future
When you pull up to a filling station in the future, just what will you be "filling up" with? Will you recharge your batteries from an electrical outlet, pump in fuel made from scrap wood or grass, or perhaps feed your fuel cell with hydrogen? Researchers at the US Department of Energy are working on all of these options to power our cars in cleaner, practical, and cost competitive ways.
23-Jun-2008 Nuclear power option for developing nations gaining steam
Global energy demand is forecast to be 50 percent higher in 2030 than it is today and according to the International Energy Agency, seventy percent of this growth is expected to come from developing countries.
The question is: what will provide the additional energy?
25-Apr-2008 DOE and DOD launch ENERGY STAR Operation Change Out
US Secretary of Energy Samuel W. Bodman on Earth Day launched a joint Department of Energy and Defense campaign to challenge military bases nationwide to change their incandescent light bulbs to energy efficient compact fluorescent light bulbs in on-base housing. The ENERGY STAR campaign, called Operation Change Out, will help bases across the country increase energy efficiency, save money and reduce carbon dioxide emissions.
28-Mar-2008 US Department of Energy to provide up to $2.4M to advance solar energy in 12 US cities
US Department of Energy Secretary Samuel W. Bodman today announced that DOE will make available up to $2.4 million to 12 cities across the country selected as Solar America Cities, chosen for their commitment and comprehensive approach to the deployment of solar technologies and the development of sustainable solar infrastructures. These projects further President Bush's Solar America Initiative, which aims to make electricity from solar photovoltaics cost-competitive with conventional electricity by 2015.
29-Feb-2008 US Department of Energy welcomes the UK as 21st member of the Global Nuclear Energy Partnership
The US Department of Energy today welcomed the United Kingdom as the Global Nuclear Energy Partnership's twenty-first partner. GNEP, a voluntary international partnership, aims to safely and securely expand nuclear power worldwide while responsibly managing nuclear waste and reducing proliferation risks. US Energy Secretary Samuel Bodman met with UK Secretary of State for Business, Enterprise and Regulatory Reform, Rt. Hon. John Hutton prior to the UK signing the GNEP Statement of Principles in Washington, DC.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
