Solar Decathlon 2013: Going the Distance

As if designing and building solar-powered houses that are cost-effective, energy-efficient, and attractive wasn’t challenging enough, the teams competing in the Solar Decathlon must also overcome another hurdle: Safely transporting their houses to the competition site in Irvine, California. Whether the houses have to travel 50 miles or 10,000, the transportation decisions the teams make can directly impact their final design.
Early on, teams must decide how they will move their houses, the appliances and furniture for public exhibit, and all the equipment necessary to reassemble the house for the competition. Not only do they have to consider transportation costs, the teams also have to factor in the size restrictions for each mode of transportation. And since the teams only have nine days to reassemble their houses before the start of the competition, they have to plan down to the minute the arrival of their house to the competition site. For the complete story, see the Solar Decathlon websiite and Energy Blog.

DOE and Georgetown University to Speed Local Energy Efficiency

The U.S. Department of Energy (DOE) and Georgetown University signed a Memorandum of Understanding (MOU) agreement on September 17 to collaborate on the Georgetown University Energy Prize, a competition to encourage innovative, replicable, and scalable approaches to reducing energy use in communities across the United States. Aimed at increasing the number of municipalities, utilities, and individuals working to save energy in their homes and communities, the MOU supports President Obama's Climate Action Plan by pursuing greater energy efficiency that reduces greenhouse gases and saves consumers money.
Beginning in February 2014, U.S. municipalities ranging in population from 5,000-250,000 residents will be eligible to compete for the prize by reducing their energy use. Participating communities must develop a long-term energy efficiency plan and demonstrate initial effectiveness and sustainability during a two-year period. The winning community will receive $5 million provided by private sponsors, which will help to support their continuing community-based energy efficiency efforts. Interested parties are invited to learn more about Georgetown Energy Prize, review the competition's rules and timeline, and register their communities in advance of the formal launch in February. The Energy Department's Building Technologies Office will advise the Georgetown University Energy Prize in refining competition guidelines, promoting the prize among key stakeholders, and providing technical assistance to participating communities.

ARPA-E Awards $66 Million for Transformational Technologies

The Energy Department announced on September 19 that 33 breakthrough energy projects will receive approximately $66 million from the Advanced Research Projects Agency-Energy (ARPA-E). The support comes under two new programs, one designed for recycling metals for lightweight vehicles, and the other to develop biological technologies to convert biogas to liquids for transportation fuels. Funding will go to recipients in 15 states: California, Colorado, Illinois, Indiana, Kentucky, Massachusetts, Missouri, Nevada, New Jersey, North Carolina, Ohio, Pennsylvania, Texas, Utah, and Washington.
The Modern Electro/Thermochemical Advancements for Light-metal Systems (METALS) program provides $32 million to find cost-effective and energy-efficient manufacturing techniques to process and recycle metals such as aluminum, magnesium, and titanium, which are ideal for creating lighter vehicles that can save fuel and reduce carbon emissions. For example, the Palo Alto Research Center in Palo Alto, California will develop a new electrochemical diagnostic probe that can identify the composition of light metal scrap for efficient sorting, which could reduce energy consumption, carbon emissions, and costs by enabling recycling of typically discarded light metal scrap.
The Reducing Emissions using Methanotrophic Organisms for Transportation Energy (REMOTE) program provides $34 million to find advanced biocatalyst technologies that can convert biogas to liquid fuel for transportation. This program aims to lower the cost of gas to liquid conversion while enabling the use of low-cost, low-carbon, domestically-produced natural tgas. For example, GreenLight Biosciences, in Medford, Massachusetts will develop a cell-free bioreactor that can convert large quantities of methane-to-liquid fuel in one step, which could enable mobile fermenters to access remote sources of natural gas for low-cost conversion of natural gas to liquid fuel.

Study Shows Solar Manufacturing Costs Not Driven Primarily by Labor

Study Shows Solar Manufacturing Costs Not Driven Primarily by Labor

Production scale, not lower labor costs, drives China's current advantage in manufacturing photovoltaic (PV) solar energy systems, according to a new report released on September 5 by the Energy Department's National Renewable Energy Laboratory (NREL) and the Massachusetts Institute of Technology (MIT). Although the prevailing belief is that low labor costs and direct government subsidies for PV manufacturing in China account for that country's dominance in PV manufacturing, the NREL/MIT study shows that a majority of the region's competitive advantage comes from production scale—enabled, in part, through preferred access to capital (indirect government subsidies) —and resulting supply-chain benefits. The study's findings suggest that the current advantages of China-based manufacturers could be reproduced in the United States.
"Assessing the Drivers of Regional Trends in Solar Photovoltaic Manufacturing," co-authored by NREL and MIT, and funded by the Energy Department through its Clean Energy Manufacturing Initiative, was published in the peer-reviewed journal Energy & Environmental Science. By developing manufacturing cost models, the team of researchers examined the underlying causes for shifts from a global network of manufactures to a production base that is now largely based in China. The study shows that China's historical advantage in low-cost manufacturing is mainly due to advantages of production scale, and is offset by other country-specific factors, such as investment risk and inflation. The authors also found that technology innovation and global supply-chain development could enable increased manufacturing scale around the world, resulting in broader, subsidy-free PV deployment and the potential for manufacturing price parity in most regions.

Electricity storage how-to guide available

Sandia Labs News Releases

Electricity storage how-to guide available

ALBUQUERQUE, N.M. — Sandia National Laboratories has released an updated handbook on energy storage, an internationally known resource for utilities, regulators and others interested in electricity storage and power generation.
The book was created in collaboration with the Electric Power Research Institute (EPRI) and the National Rural Electric Cooperative Association (NRECA) and was funded by the Department of Energy’s Office of Electricity Delivery and Energy Reliability. A 10-member advisory panel representing all segments of the storage community guided the book’s development, including people from electric utilities, regulators, system vendors and industry associations.
“The handbook will fill an industrywide need for a single resource representing the state of the art of energy storage,” said Imre Gyuk, program manager of the energy storage program of DOE’s Office of Electricity Delivery and Energy Reliability.
Gyuk said he hopes that the handbook will help put energy storage well on the road to full commercialization.
The handbook guides readers through topics based on their role, allowing utilities, system suppliers, regulators, consultants and the public to quickly find what they need to evaluate and assess energy storage options for all types of grid-connected enterprises.
Sandia project lead Georgianne Huff said the handbook reviews available and emerging storage technologies in terms of important considerations such as cost, performance and technology maturity. It also provides quantitative data on performance, design features and life-cycle costs.
Lead author Abbas Akhil said the handbook provides detailed information on storage technologies, ways in which they’re best applied and their life cycle costs. Akhil said the handbook also reviews analytical tools and describes the regulatory framework that adds incentives to the implementation of energy storage.
“Energy storage can be a valuable option in maintaining the high reliability and low cost of the modern grid. The book will be a valuable tool to utilities, regulators and others who are interested in deploying grid storage systems in a safe, reliable and cost-effective way,” said Haresh Kamath, program manager for energy storage at the Electric Power Research Institute.
The previous edition of the handbook was published in 2003, when there were only a few demonstration projects and almost no commercially viable technology, so the book was limited to a survey of available storage technologies and analysis of potential applications. The current edition grew from a simple survey to becoming a thorough and comprehensive implementation guide.
“We are proud to collaborate on a tool that will spur new developments in the ongoing research on viable and economical methods of storing electricity,” said Martin Lowery, NRECA’s executive vice president of Member & Associate Relations.
Huff said the team hopes the handbook will help lead to improved technology, greater deployment of new and renewable power generation and a well-structured regulatory environment, all of which will help implement a smarter and more flexible electric power grid.

Solar Decathlon 2013: Designing the Houses of Today

Designing an energy-efficient, solar-powered house for the Solar Decathlon is like solving a riddle that has more than one right answer. Instead of just thinking about building materials and cost in the design process, teams have to consider a myriad of factors to create a winning house.
While the design process never officially ends, the teams spend more than a year focusing on the design before breaking ground on their houses. Early on in the process, they select a target client for their house—one of the biggest impacts on their final design—and decide how they will transport their house to the competition site. The teams also have to make sure their designs meet contest criteria and rules—such as staying within a specified square footage, not exceeding solar array dimensions, and being accessible to visitors with disabilities. Throughout the process, the teams are required to submit construction plans and documentation, which are reviewed by the Solar Decathlon organizers for building code and rules compliance. Once their designs are complete, the teams can start constructing their houses. Visit the U.S. Department of Energy Solar Decathlon 2013 website and for the complete story, read the Energy Blog.

USDA Awards $15 Million for Advanced Biofuels

USDA Awards $15 Million for Advanced Biofuels

The U.S. Department of Agriculture (USDA) announced on September 12 that it is making more than $15 million in investments to support the production of advanced biofuel. USDA is funding 188 producers through the Advanced Biofuel Payment Program.
For example, Riverview, LLP, a Minnesota-based company, will use a payment to support a project that produces electricity from two anaerobic digesters which use manure from two of the company's dairy operations to produce electricity. During the last quarter of 2012, the anaerobic digesters produced almost 4.9 million kilowatt hours of electricity, enough to power more than 400 homes a year. And American Biodiesel, Inc. in California will receive payment for its quarterly production of biodiesel from a variety of sources, including canola and soybean oil. The biodiesel reduces emissions and is primarily used as an alternative to diesel fuel. See the USDA press release.

Energy Department, EPA Release Used-Vehicles Fuel Economy Tool

Energy Department, EPA Release Used-Vehicles Fuel Economy Tool

The Energy Department and the Environmental Protection Agency (EPA) on September 12 released a new label that features EPA fuel economy estimates and carbon dioxide estimates for used vehicles sold in the United States since 1984. Consumers may create the new label electronically using a new tool on FuelEconomy.gov. This electronic graphic can be downloaded and included in online advertisements on the web, while the paper label may be printed and affixed to the vehicle window. Because a vehicle's fuel economy changes very little over a typical 15-year life with proper maintenance, the original EPA fuel economy estimate remains the best indicator of a used vehicle's average gas mileage.
The Obama Administration has taken steps to improve the fuel efficiency of vehicles sold in the United States, establishing the toughest fuel economy standards for passenger vehicles in U.S. history. These standards are expected to save consumers $1.7 trillion at the pump—or more than $8,000 in costs over the lifetime of each vehicle—and eliminate six billion metric tons of carbon pollution.
All new vehicles now include a comprehensive fuel economy and environmental window sticker from the EPA, including passenger vehicles that meet the new fuel economy standards. With the FuelEconomy.gov tool, used vehicle sellers can provide potential buyers with fuel economy information that they can easily understand. Last year, more than 40 million used cars were sold in the United States—roughly three times the number of new cars sold in 2012. See the Energy Department Progress Alert and theFuelEconomy.gov website.

University of Maryland Wins Appliance Design Competition

The Energy Department announced September 10 that the University of Maryland won the second annual Max Tech and Beyond design competition for ultra-low energy use appliances and equipment for the second year in a row. The team developed a heat pump clothes dryer that is nearly 59% more efficient than a traditional electric dryer. The winning prototype will be on display at this year's U.S. Department of Energy Solar Decathlon in Irvine, California. With a comprehensive business plan, Ohio State University placed second in the challenge for its hybrid air/water conditioner that can achieve nearly a 73% energy cost savings over a conventional central air conditioning, dehumidification, and ventilation system.
The Max Tech and Beyond competition challenges university teams to go beyond the current "max tech," or maximum technology performance levels, by exploring new design concepts that could become the next generation of ultra-low energy use appliances and equipment. Funded by the Energy Department's Building Technologies Office and managed by Lawrence Berkeley National Laboratory, the competition encourages participating students to connect with U.S. manufacturers and license their designs after successful demonstration. In total, eight teams spent the 2012-2013 academic year in their respective laboratories, fine-tuning their innovative technologies and gaining valuable knowledge of energy efficiency. These efforts helped to produce ultra-efficient prototypes for demonstration and deployment in the global clean energy market. See the Energy Department Progress Alert.

Energy Secretary Dedicates ESIF at NREL

On Wednesday, September 11, Energy Secretary Ernest Moniz dedicated a new federal lab building he said will be crucial to bringing more renewable energy onto the nation's energy system and building the reliable, clean energy infrastructure America vitally needs.
Moniz officially dedicated the Energy Systems Integration Facility (ESIF) at the Energy Department's National Renewable Energy Laboratory (NREL), where industry and utilities will go to demonstrate their new equipment and strategies at megawatt scale.
The ESIF "will be a major focus of DOE to help us transform the energy system to the one we need in 2030," Moniz said before a packed crowd of scientists, policymakers, and industry leaders at NREL's Golden, Colorado, campus.
Moniz, who was confirmed as Energy Secretary in May, said tremendous advances in wind, solar, and fuel cell energy have pushed those technologies to the threshold of being major presences on the nation's electricity grid.
However, that presents a challenge because solar and wind are intermittent resources. And that challenge is complicated by increased severe weather events such as Hurricane Sandy that knocked out power in 21 states last year, Moniz said, emphasizing the need for a more resilient infrastructure in the near future.

Climate Action Plan to Guide Policy

The Secretary's first weeks on the job coincided with President Obama unveiling his Climate Action Plan, which focuses on doing more to address the risks of climate change. "I said that first day, 'I'm not here to debate the undebatable,'" Moniz said, referring to the strong belief among almost all climate scientists that the Earth is getting warmer due in part to fossil-fuel emissions in the atmosphere.
"We need to frankly acknowledge that we are facing the effects of climate change even as we try to kind of beat the clock with mitigation and adaptation," Moniz said. "Our script comes from the President's Climate Action Plan. Both mitigation and adaptation to climate change are very much part of that agenda."
So now the nation's focus must be on energy integration — on delivering distributed energy to the grid when the sun shines and the wind blows, while keeping it as reliable as when the grid was a one-way delivery system of fossil-fuel-based energy, Moniz said. The new ESIF is "the step up we need to elevate the focus on energy systems integration."
The ESIF will also play a key role in helping regional utilities design resilient microgrids that will bring back power almost immediately to communities that now are bathed in darkness when storms such as Hurricane Sandy hit, Moniz said. "We need to reap the benefits of our tremendous technological advances to start developing solutions for our energy system."

Supercomputer's Green Data Center Teamed NREL with HP

Just before his talk, Moniz pushed a button that inaugurated the ESIF's high performance computer Peregrine, which can do more than a quadrillion calculations per second and is integral to the ESIF's capabilities.  Peregrine supports NREL's research into energy systems integration, renewable energy research, and energy efficiency technologies, and will lead to increased efficiency and lower costs for clean energy technologies. NREL teamed with Hewlett-Packard to develop the supercomputer.
Paul Santeler, vice president of the Hyperscale Business Group at Hewlett-Packard, said the collaboration with NREL on the high performance computer and  data center was the best partnership he's been a part of because both the company and laboratory learned so much — knowledge that will help other data centers go deep green. The data center for the Peregrine supercomputer in the ESIF is unique, because it uses the excess heat generated by the computer to warm water, and then uses that water to heat the entire building.
"When Steve Hammond [director of NREL's Computational Science Center] told me wanted to put in a petaflop-scale high performance computer, and that he wanted to cool it with warm water and use that water that comes off to heat the building, and then use the excess heat to warm the cement outside, I said, 'Riiight,'" Santeler said. "We were doing something very unique and different — breaking boundaries. But the bottom line is, we nailed it. And we're making it commercially available so others can take advantage."
Moniz got a firsthand look at the ESIF's computing capabilities when he went into the ESIF's visualization room, donned special glasses, and saw on a 16-foot, 3-D-like screen how wind turbine blades can alter the wind flow as it approaches other turbines downstream. The same visualization room can give scientists a shifting, human-sized view of the inside of the molecules of a solar cell or biofuel.
"This will take us to a whole new ballgame," Moniz said. "It's an enormous advantage."

Utility CEO Stresses the Importance of Energy Integration

Xcel Energy CEO and Chairman Ben Fowke said the ESIF will grow even more important now that solar and wind are in many cases cost competitive with fossil fuels. He noted that Xcel leads the nation in wind power. His company now can purchase 20 years of wind power for less money than the comparable megawatts from natural gas, saving customers $800 million over the next two decades.
Wind forecasting software developed at NREL and elsewhere saved Xcel $20 million last year alone, and NREL research on the effect of cloud cover on solar energy will save even more, he said. Better forecasting means utilities can be more confident about the reliability of renewables, and that means less need for reserve power.
"We can really unlock the power of the future beginning today," Fowke said. "We're really excited about this next chapter in NREL's progress, and the integration of distributed resources into our grid. I'm confident our mission to deliver safe, clean, reliable power at a competitive price is in good hands because of partners like NREL."
Later, Fowke noted that Xcel during certain hours uses 80% wind energy, and so far it's gone off without a hitch. "Our number-one job is to make sure our customers can rely on the lights staying on," he said. "As the energy portfolio diversifies, we'll be depending on wind and solar forecasts and the capabilities of the ESIF more than ever."

The Energy Department also made two other important announcements while the Secretary was at NREL.
NREL will work with the Energy Department and Toyota North America to research ways to integrate plug-in electric vehicles into the power grid. Scientists and engineers at the ESIF and NREL's Vehicle Testing and Integration Facility will use 20 Prius plug-in hybrid electric vehicles to develop and explore ways to help grid operators accommodate the fast-growing U.S. electric vehicle fleet.
Tom Stricker, vice president of energy and environmental research for Toyota North America, said "this new, amazing facility" will be crucial to analyzing the grid effects of Toyota's new plug-in Priuses. Hybrid, plug-in electric, and alternative fuel vehicles now comprise 16% of all Toyotas sold, he noted.
Stricker also said that Toyota will reveal its first production hydrogen fuel cell vehicle — a mid-sized sedan — at the Tokyo Motor Show in November. Its North American debut will be at the Consumer Electronics Show in Los Angeles in December.
He said Toyota will continue to work closely with NREL researchers at the ESIF. "We need continued collaboration between industry and government to solve the problems we face."
NREL is also working with the U.S. Army to develop a power system comprised of solar energy, battery power, and generators that can provide electricity to forward operating bases. Using the integrated test capabilities of the ESIF, NREL will complete a prototype of the Consolidated Utility Base Energy (CUBE) system and validate its performance, reliability, and projected energy savings.

ESIF's Role Will Be Transformative

NREL Director Dan Arvizu said that without partners such as Toyota, Xcel, Hewlett-Packard, and the Energy Department, the ESIF wouldn't be what it is.
The ESIF will allow industry decision makers to model what an increasing penetration of solar or wind energy onto the grid would look like in real time, at a level of accuracy and detail never seen before, Arvizu said.
Manufacturers can test new energy equipment at megawatt power, Arvizu added. Vendors can analyze the optimal equipment balance as the energy system adds storage and two-way data sharing. ESIF brings together pertinent tools to integrate technologies in ways that weren't possible before.
David Danielson, the Energy Department's assistant secretary of energy for renewable energy and energy efficiency, lauded NREL for having the vision seven years ago to know that such a facility as ESIF was needed — and for pushing for it with the Department. "At every step, NREL provides critical leadership that guides policy."

Technological Success Speeds the Move to Energy Integration

Moniz noted that for solar, wind, light-emitting diodes (LEDs), and fuel cell batteries, the past few decades have seen plummeting prices and a huge rise in deployment.
The cost of solar power has plummeted 99%; wind led all technologies in new deployments last year; the price of LED bulbs has fallen from $50 to $15, and each one can save a homeowner $100 over a lifetime; and fuel cell prices have dropped sharply, while safety and longevity have improved greatly.
"A lot of us still have this lingering idea that these technologies are five or 10 years away, but really, we are on the threshold," Moniz said. "Each of these will be a material part of our energy system very soon."
That makes the ESIF and the successful integration of myriad forms of energy all the more crucial, Moniz added. Referring to the battering the nation's infrastructure took from recent extreme weather events such as Hurricane Sandy, and the need for a more flexible, integrated system that accommodates clean energy, Moniz said: "Mother Nature is pointing out that if we don't take care of our energy system, she will."

Sandia Labs harnessing the sun’s energy with tiny particles

Falling particle receiver

ALBUQUERQUE, N.M. – Engineers at Sandia National Laboratories, along with partner institutions Georgia Tech, Bucknell University, King Saud University and the German Aerospace Center (DLR), are using a falling particle receiver to more efficiently convert the sun’s energy to electricity in large-scale, concentrating solar power plants.
Falling particle receiver technology is attractive because it can cost-effectively capture and store heat at higher temperatures without breaking down, which is an issue for conventional molten salts. The falling particle receiver developed at Sandia drops sand-like ceramic particles through a beam of concentrated sunlight, and captures and stores the heated particles in an insulated container below. The technique enables operating temperatures of nearly 1,000 degrees Celsius. Such high temperatures translate into greater availability of energy and cheaper storage costs because at higher temperatures, less heat-transfer material is needed.
Central receiver systems use mirrors to concentrate sunlight on a target, typically a fluid, to generate heat, which powers a turbine and generator to produce electricity. Currently, such systems offer about 40 percent thermal-to-electric efficiency. The falling particle receiver enables higher temperatures and can work with higher-temperature power cycles that can achieve efficiencies of 50 percent or more.
“Our goal is to develop a prototype falling particle receiver to demonstrate the potential for greater than 90 percent thermal efficiency, achieve particle temperatures of at least 700 degrees Celsius, and be cost competitive,” said the project’s principal investigator, Sandia engineer Cliff Ho. “The combination of these factors would dramatically improve the system performance and lower the cost of energy storage for large-scale electricity production.”
The project is funded up to $4 million by the Department of Energy’s SunShot Initiative, which aims to drive down solar energy production costs and pave the way to widespread use of concentrating solar power and photovoltaics.
Sandia Concentrating Solar Power at SolarPACES Conference – Cliff Ho, principal investigator of the Falling Particle Receiver project, will be available to discuss his work at the2013 SolarPACES conference in Las Vegas on Tuesday, Sept. 17-Friday, Sept. 20. Ho recently earned a R&D 100 Award for his Solar Glare Hazard Analysis Tool. Several Sandia researchers, including Chuck Andraka (large-scale optical metrology and modeling) and David Gill (thermal energy storage) will also be available to discuss other Sandia innovations in concentrating solar power and ongoing work at the newly renovated National Solar Thermal Test Facility (NSTTF). Members of the media who desire interviews should contact Stephanie Holinka,slholin@sandia.gov or 505-284-9227.
Falling particle receiver technology was originally studied in the 1980s, and Sandia researchers are working to address challenges that hindered greater acceptance of the concept. Among the issues are mitigating particle loss, maintaining the stability of falling particles, increasing the residence time of the particles in the concentrated beam and reducing heat losses within the receiver cavity.
Ho and his colleagues at Sandia have been working to address these issues by studying the effect of an added air curtain, created by a series of blower nozzles, to help particles fall in a stable pattern and reduce convective losses. Adjusting the particle size and how sand is dropped has also helped, ensuring more of the sand gets heated in a pass and makes it to the collection bin at the bottom. Researchers are also investigating the benefits of using an elevator to recirculate particles through the aperture a second time to increase their temperature.
“Given our unique facilities at the National Solar Thermal Test Facility, we have the capability of developing prototype hardware and testing the concepts we’ve simulated, which include innovations such as air recirculation and particle recirculation. Advanced computing lets us do complex simulations of the falling particle receiver to understand the critical processes and behavior,” Ho said. “We’re very encouraged by our progress and look forward to further developing this enabling technology.”
Falling particle receiver technology is expected to lead to power-tower systems capable of generating up to 100 megawatts of electricity. The project is in its first of three years, and a test-ready design is expected in 2015.

Sandia National Laboratories is a multi-program laboratory operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin company, for the U.S. Department of Energy’s National Nuclear Security Administration. With main facilities in Albuquerque, N.M., and Livermore, Calif., Sandia has major R&D responsibilities in national security, energy and environmental technologies and economic competitiveness.

Deputy Secretary Krysta Harden joined leaders from the Alliance for Green Heat, the Biomass Power Association, the Biomass Thermal Energy Council, and the Pellet Fuels Institute here in Washington for the announcement of a new partnership agreement. Acting as master of ceremonies for the signing event was Acting USDA Rural Development Under Secretary Doug O’Brien.  Through the Rural Energy for America program and other programs, Rural Development has been a leader in promoting deployment of wood-to-energy projects.
This agreement focuses on promoting wood energy nationwide to reduce fire risk, bolster rural economic development, improve air quality and help meet the Obama Administration’s “All of the Above” renewable energy and energy efficiency goals. The organizations support the use of wood energy across the scale of users – from residential users, to commercial and institutional facilities, to industrial production of heat and/or electricity to drive businesses and feed the electrical grid.
For more than a decade, USDA has supported wood energy as part of a forest restoration economy. Since 2009 USDA has invested over $956 million (nearly $1 billion) through grants, loans, and loan guarantees to support over 200 wood energy projects across the country.
Led by the Forest Service, this work helps to restore the health of forests and watersheds, provide rural areas with cost-effective energy alternatives, and create new income and employment opportunities in sectors ranging from engineering and construction, to manufacturing and forestry. It also provides an economical alternative to fuel oil heating in areas where natural gas supplies are limited. USDA’s Rural Development mission area and the Farm Services Agency also support wood energy through a variety of grants, loans, and loan guarantees. All told, USDA agencies contributed over $500 million last year to support wood energy.
The Deputy Secretary also announced the award of over $1 million dollars in grants to develop wood energy teams with Alaska, California, Idaho, Minnesota and New Hampshire. These cooperative agreements signal that successful wood energy projects and forest restoration efforts demand partnership at all levels as well as the sustained commitment of many and diverse forest users.  The federal funds will leverage $1.8 million in non-federal investments.
Grant recipients are:
Idaho Governor’s Office of Energy Resources, Boise
The Watershed Research & Training Center, Hayfork, Calif.
Minnesota Department of Natural Resources, Saint Paul
North Country Resource Conservation & Development Council, Gilford, N.H.
The Alaska Energy Authority, Anchorage

Solar Decathlon 2013: Meet the Teams

On October 3, collegiate teams from across the globe will converge at Orange County Great Park in Irvine, California, for the final phases of the U.S. Department of Energy Solar Decathlon 2013.
For two years, these teams have worked to design and build solar-powered houses that are affordable, energy efficient, and attractive, while also testing the houses to ensure they produce as much energy as they use. In early October—after their houses have been reassembled at the competition site—the teams will go head-to-head in 10 contests and showcase their houses to the public, all with the hopes of being crowned the winning team.
But before the teams could even compete in the Solar Decathlon, they had to make it through a rigorous selection process. As Solar Decathlon 2011 was finishing up, more than 40 hopeful teams were already hard at work preparing their proposals, creating draft design plans and demonstrating that they could meet specific criteria necessary to take part in the two-year competition—such as being able to assemble a core team for the entire competition and supporting the competition with curriculum. For nearly two months, a panel of engineers, scientists and building experts reviewed, scored, and ranked the applications before narrowing the list of competitors in half. Towards the end of January 2012, the Energy Department notified the collegiate teams that they had been selected to compete—officially kicking off the Solar Decathlon 2013 competition. For the complete story, see the Energy Blog and the U.S. Department of Energy Solar Decathlon 2013 website.

USDA Awards $11 Million in Loans for Smart Grid

The U.S. Department of Agriculture (USDA) on September 5 announced funding for projects in eight states—Iowa, Kansas, Missouri, New Mexico, North Carolina, Ohio, Texas, and Virginia—to improve electric service for about 10,000 rural residents. The loan guarantees are provided through USDA's rural utilities program and include more than $11 million in smart grid project funding.
For example, the Central Virginia Electric Cooperative will use USDA funding to build 327 miles of line and invest more than $1.1 million in smart grid technologies across 14 counties. And Ohio's South Central Power Company will use the funds to build 558 miles of distribution line, 34 miles of transmission line, and make other system improvements, includiing the investment of nearly $1.2 million in smart grid projects.

DOI Holds Second Competitive Offshore Wind Lease Sale

The U.S. Department of the Interior (DOI) on September 4 completed the nation’s second competitive lease sale for renewable energy in federal waters, garnering $1.6 million in high bids for 112,799 acres offshore of Virginia. Virginia Electric and Power Company is the provisional winner of the sale, which auctioned a Wind Energy Area approximately 23.5 nautical miles off Virginia Beach that has the potential to support 2,000 megawatts of wind generation—enough energy to power more than 700,000 homes. The sale follows a July 31 auction of 164,750 acres offshore Rhode Island and Massachusetts for wind energy development that was provisionally won by Deepwater Wind New England, LLC, generating $3.8 million in high bids.
The leaseholder will have a preliminary term of six months in which to submit a Site Assessment Plan to DOI's Bureau of Ocean Energy Management (BOEM) for approval. A Site Assessment Plan describes the activities (e.g., installation of meteorological towers and buoys) the leaseholder plans to perform for the assessment of the wind resources and ocean conditions of its commercial lease area. After a Site Assessment Plan is approved, the leaseholder will have up to four and a half years in which to submit a Construction and Operations Plan (COP) for approval, which will provides a detailed outline for the construction and operation of a wind energy project on the leased property. If the COP is approved, the leaseholder will have an operations term of 33 years. See the DOI press release.

Energy Department Awards $45 Million for Advanced Transportation

The Energy Department on September 4 announced more than $45 million in funding for 38 new projects that will accelerate the research and development of vehicle technologies to improve fuel efficiency, lower transportation costs, and protect the environment. Through the Advanced Vehicle Power Technology Alliance between the Energy Department and the U.S. Department of the Army, the Army is contributing an additional $3 million in co-funding to support projects focused on "lightweighting" and propulsion materials, batteries, fuels, and lubricants.
The 38 projects span five major areas critical to advanced transportation technologies. Fifteen projects will research advanced lightweighting and propulsion materials, which are essential for boosting the fuel economy of cars and trucks while maintaining and improving safety and performance. Thirteen projects will focus on advanced batteries, helping to improve cell chemistry and composition, develop advanced electrolytes, and create new battery design tools to further reduce battery costs. Four projects will target power electronics to improve plug-in electric vehicle (EV) inverters. Two projects will seek to reduce the impact of heating and cooling on EVs in order to significantly increase all-electric driving range. And four projects will develop advanced fuels and lubricants that can reduce friction losses and increase the efficiency of cars already on the market, as well as next-generation passenger vehicles.
The 38 new projects support the goals of the Energy Department’s EV Everywhere Grand Challenge, a broader initiative to make EVs as affordable and convenient to own and drive as gasoline-powered vehicles within 10 years. See the complete list of projectsPDF and the Energy Department press release.
