NREL Creates New Pathways for Producing Biofuels and Acids from Cyanobacteria (Fact Sheet)

Description: Cyanobacteria use photosynthesis to convert carbon dioxide into glycogen, a carbohydrate that is stored in the cells as an energy source. However, researchers at the National Renewable Energy Laboratory (NREL) have discovered that this photosynthesis can be redirected to produce lipids and valuable organic acids. The research could yield a new source of biofuels, because the lipids can potentially be extracted from the bacteria and converted into biodiesel.

NREL Designs Promising New Oxides for Solar Cells (Fact Sheet)

Description: High-efficiency, thin-film solar cells require electrical contacts with high electrical conductivity, and the top contact must also have high optical transparency. This need is currently met by transparent conducting oxides (TCOs), which conduct electricity but are 90% transparent to visible light. Scientists at the National Renewable Energy Laboratory (NREL) have derived three key design principles for selecting promising materials for TCO contacts. NREL's application of these design principle… more

NREL Develops New Controls that Proactively Adapt to the Wind (Fact Sheet)

Description: Until now, wind turbine controls that reduce the impacts of wind gusts and turbulence were always reactive-responding to the wind rather than anticipating it. But with today's laser-based sensors that measure wind speed ahead of the turbine, researchers at the National Renewable Energy Laboratory (NREL) and their industry partners are developing more intelligent controls. The world's first field tests of these controls are currently underway at the National Wind Technology Center (NWTC) at NREL… more

NREL Explores Earth-Abundant Materials for Future Solar Cells (Fact Sheet)

Description: Researchers at the National Renewable Energy Laboratory (NREL) are using a theory-driven technique - sequential cation mutation - to understand the nature and limitations of promising solar cell materials that can replace today's technologies. Finding new materials that use Earth-abundant elements and are easily manufactured is important for large-scale solar electricity deployment.

NREL Helps Clean Cities Displace Billions of Gallons of Petroleum, One Vehicle at a Time (Fact Sheet)

Description: With more than 15 years and nearly 3 billion gallons of displaced petroleum under its belt, the Clean Cities program relies on the support and expertise of the National Renewable Energy Laboratory (NREL). An initiative of the U.S. Department of Energy (DOE), Clean Cities creates public-private partnerships with a common mission: to reduce petroleum consumption in the transportation sector. Since the inception of Clean Cities in 1993, NREL has played a central role in supporting the program, an … more

NREL Helps Greensburg Set the Model for Green Communities (Fact Sheet)

Description: After a massive tornado destroyed or severely damaged 95% of Greensburg, Kansas on May 4, 2007, key leaders in Greensburg and Kansas made a crucial decision not just to rebuild, but to remake the town as a model sustainable rural community. To help achieve that goal, experts from the U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL) arrived in Greensburg in June 2007.

NREL Melds Nature with Nanotech for Solar-Powered Hydrogen Production (Fact Sheet)

Description: NREL researchers are finding ways to mimic photosynthesis by combining enzymes with nanoparticles - particles on the scale of a billionth of a meter - to produce hydrogen directly from water and sunlight. This breakthrough project began in 2008 with scientists and researchers asking how they might learn from nature and develop a synthetic process that is more efficient than plants at converting sunlight to hydrogen. The goal was to find a new way to produce hydrogen that could then be commercia… more

NREL Paves the Way to Commercialization of Silicon Ink (Fact Sheet)

Description: In 2008, Innovalight, a start-up company in Sunnyvale, California, invented a liquid form of silicon, called Silicon Ink. It contains silicon nanoparticles that are suspended evenly within the solution. Those nanoparticles contain dopant atoms that can be driven into silicon solar cells, which changes the conductivity of the silicon and creates the internal electric fields that are needed to turn photons into electrons -- and thus into electricity. The ink is applied with a standard screen prin… more

NREL Reveals Links Among Climate Control, Battery Life, and Electric Vehicle Range (Fact Sheet)

Description: Researchers at the National Renewable Energy Laboratory (NREL) are providing new insights into the relationships between the climate-control systems of plug-in electric vehicles and the distances these vehicles can travel on a single charge. In particular, NREL research has determined that 'preconditioning' a vehicle-achieving a comfortable cabin temperature and preheating or precooling the battery while the vehicle is still plugged in-can extend its driving range and improve battery life over … more

NREL Scientists Spurred the Success of Multijunction Solar Cells (Fact Sheet)

Description: Before 1984, many scientists believed that high-quality gallium indium phosphide (GaInP) alloys could not be grown for use as semiconductors because the alloys would separate. One researcher at the Solar Energy Research Institute (SERI) thought differently. His name was Jerry Olson, and his innovative thinking changed solar history. Olson identified a material combination that allowed the multijunction cell to flourish. It is now the workhorse that powers satellites and the catalyst for renewed… more

NREL's Wind Powering America Team Helps Indiana Develop Wind Resources (Fact Sheet)

Description: How does a state advance, in just five years, from having no installed wind capacity to having more than 1000 megawatts (MW) of installed capacity? The Wind Powering America (WPA) initiative, based at the National Renewable Energy Laboratory (NREL), employs a state-focused approach that has helped accelerate wind energy deployment in many states. One such state is Indiana, which is now home to the largest wind plant east of the Mississippi.

Rapid Deposition Technology Holds the Key for the World's Largest Solar Manufacturer (Fact Sheet)

Description: Thanks in part to years of collaboration with the National Renewable Energy Laboratory (NREL), a manufacturer of thin-film solar modules has grown from a small garage-type operation to become the world's largest manufacturer of solar modules. First Solar, Inc. now manufactures cadmium telluride (CdTe) solar modules throughout the world, but it began in Ohio as a small company called Solar Cells, Inc.
