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.
27-Dec-2007 DOE to invest more than $5M for concentrating solar power
US Department of Energy Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner today announced DOE will invest $5.2 million in funding to support the development of low-cost Concentrating Solar Power.
16-Oct-2007 Energy savings deeply rooted at Jefferson Lab
When it comes to energy savings, Jefferson Lab has given a new meaning to dirt cheap. The lab uses a geothermal well system to control heating and cooling on two floors of one wing of its main administrative building. The wing, known as the F Wing, is a three-story, 61,000-square-foot addition that was constructed in 2005.
15-Jun-2007 Cytochrome studies provide biofuel cell potential
Researchers from Pacific Northwest
National Laboratory and collaborators have
purified the protein called outer membrane
cytochrome A (OmcA) from Shewanella
oneidensis, a bacterium with promise for
bioremediation of contaminants and the
design of microbial fuel cells. They have
measured its ability to bind and transfer
electrons to mineral hematite, a solid ferric
oxide. The team has shown that purified
OmcA can directly reduce solid metals
and that purified proteins are a next step
in biofuel cell development.
5-Apr-2007 Science and Technology Facility is first LEED Platinum Federal Building
A research facility at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory has been designated as one of the most energy efficient and environmentally friendly places to work in the United States by the U.S. Green Buildings Council under its Leadership in Energy and Environmental Design (LEED) Green Building program.
22-Mar-2007 Sailing for science
When most people think of an ocean
cruise, they think of buffets and relaxing
in deck chairs. For Pacific Northwest
National Laboratory researcher Philip
Long, an expedition cruise aboard the
Joint Oceanography Institutes Deep
Earth Sampling (JOIDES) Resolution
research vessel meant 12-hour workdays
examining ocean floor core samples for
22-Mar-2007 Carbon capture made easy
Gasification plants may be one
of the keys to a hydrogen economy,
if capture and sequestration of carbon
dioxide (CO2) becomes technically
and economically feasible. These plants
would transform fossil fuel feedstock,
including coal, biomass and municipal
wastes, into clean-burning hydrogen
gas where the only byproduct is water.
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.
