Obama Administration Highlights Tools to Manage Electricity Use

The Obama Administration announced on January 18
 the launch of new online tools that will allow consumers to download
household energy use data. These tools, packaged as a website feature
called "Green Button," are designed to help households save energy and

Two of California's largest utilities—Pacific
Gas & Electric Company (PG&E) and San Diego Gas & Electric
Company—have taken the lead in launching the Green Button as a new
feature on their websites, allowing nearly six million households to
download their own detailed energy use data. Additional utilities that
collectively serve another 11.3 million households plan to make the
feature available later this year. See the Green Button page on the PG&E website.

Because Green Button is designed around an
open-data standard, it is spurring innovation among website and software
 developers interested in using that standard to provide novel
energy-saving services. The North American Energy Standards Board also
plans to make a “startup kit” available to help app developers,
students, and others take full advantage of Green Button. Green Button
is expected to support interactive thermostats and audits that recommend
 energy-efficiency retrofit improvements for homes and businesses. DOE
also plans to highlight Green Button apps on its "Energy Savers" energy information portal. See the White House press release.

DOE Reports Potential for Wave and Tidal Energy Production

DOE released on January 18 two resource
assessments showing that waves and tidal coastal currents could
contribute significantly to U.S. electricity production. The West Coast,
 including Alaska and Hawaii, has especially high potential for wave
energy development, while significant opportunities for wave energy also
 exist along the East Coast. Additionally, parts of both coasts have
strong tides that could be tapped to produce energy. Combined with other
 analyses, these assessments show that water power, including
conventional hydropower, could provide 15% of U.S. electricity by 2030.

The United States uses about 4,000 terawatt
hours (TWh) of electricity per year. DOE estimates that the maximum
theoretical electric generation that could be produced from waves and
tidal currents is approximately 1,420 TWh per year, about one-third of
the nation's total annual electricity use. Though not all of the
resource potential identified in these assessments can realistically be
developed, the results still represent major opportunities for new water
 power development, highlighting specific opportunities to expand on the
 6% of the nation's electricity already generated from hydropower

In addition to the wave and tidal resource
assessments, DOE plans to release additional resource assessments for
ocean current, ocean thermal gradients, and new hydropower resources in
2012. To support the development of technologies that can tap into these
 vast resources, DOE's Water Power Program is undertaking a detailed
technical and economic assessment of a wide range of water power
technologies in order to more accurately predict the opportunities and
costs of developing and deploying these innovative technologies. The
program is sponsoring more than 40 demonstration projects that will
advance the commercial readiness of these systems; provide
first-of-a-kind, in-water performance data that will validate
cost-of-energy predictions; and identify pathways for large cost
reductions. See the DOE Progress Alert and the Water Power Program website.

DOE announced on January 20 two opportunities
for university researchers to advance the department's SunShot
Initiative, a program that aims to dramatically decrease the total costs
 of U.S. solar energy. DOE will make up to $10 million available to
support the development of heat-transfer fluids that are more efficient,
 thus reducing the cost of energy from concentrating solar power (CSP)
systems. The department also opened the second round of SunShot
Initiative postdoctoral research awards for applied research at
universities, national laboratories, and other research facilities.

Under the solicitation for heat-transfer fluids,
 DOE will support university-based CSP research projects to develop and
demonstrate fluids that are more stable than current technologies at
temperatures greater than 800°C. CSP plants use mirrors to focus
sunlight to heat a working fluid, which generates steam that spins a
turbine or powers a heat engine that produces electricity.
Higher-temperature working fluids could enable CSP systems to couple
with heat engines that are capable of converting more than 50% of the
heat in the working fluid into electricity.

This funding will be awarded as part of the
Multidisciplinary University Research Initiative, a program designed to
advance research, accelerate technology transfer into the marketplace,
and prepare a new generation of scientists and engineers. DOE
anticipates funding one or two projects over five years through this
opportunity. For more information, see the Funding Opportunity Announcement on DOE's Funding Opportunity Exchange website.

In addition, DOE opened the next round of
SunShot Initiative postdoctoral research awards, which will provide
students the chance to work on advanced clean energy technologies.
Recipients will conduct applied research at universities, national
laboratories, and other research facilities. This program includes an
opportunity for recipients to participate in a research exchange program
 with Australia under the United States-Australia Solar Energy
Collaboration. See the DOE Progress Alert, the SunShot Postdoctoral Researchers Web page, and the SunShot Initiative website.

DOE Seeks an Administrator for the Superior Energy Performance Program

DOE issued a Funding Opportunity Announcement
(FOA) on January 19, offering up to $3 million in funding to administer
its Superior Energy Performance (SEP) program, which will help U.S.
manufacturers continually increase the energy efficiency of their
domestic facilities. The funding will support at least one organization
to launch, operate, and promote the SEP program. When launched later
this year, the voluntary program will provide a transparent,
step-by-step certification process to help industrial and commercial
facilities implement and validate improvements in their energy
performance and reduce their energy costs.

The SEP program will be a key component of DOE's
 efforts to improve energy efficiency throughout the nation's
manufacturing sector. The program administrator will be responsible for
launching and overseeing the program during its initial stages and for
developing and executing a sustainable business model, enabling SEP to
become a fee-based, self-sufficient program within three years of the
award. Eligible applicants for this funding opportunity include U.S.
domestic entities or consortia composed of academic institutions,
non-profits [except 501(c)(4) non-profits], and for-profit private
entities. Letters of intent in connection with this opportunity are due
February 21, and awards are expected by June. See the DOE Progress Alert, the FOA on DOE's Funding Opportunity Exchange website, and the SEP Web page.

Austin Using Green Innovation to Beat the Utility Blues

Sewage treatment has always been a dirty
business, dating back to the frontier days when "waste management" meant
 the guy who followed after the horses with a bucket and shovel.
However, thanks to modern technology, there are ways to turn some of the
 treatment processes into clean energy that can power public
infrastructure facilities.

The Hornsby Bend Biosolids Management Plant in
Austin, Texas, located on 1,200 acres of land along the Colorado River,
is a national model for innovative approaches to improve the
environment, such as reducing waste, producing compost, and protecting
ecosystems. Each year, thousands of tons of biosolids, the nutrient-rich
 organic materials resulting from the treatment of sewage sludge, are
anaerobically digested and composted with Austin's yard trimmings into
an EPA-certified soil conditioner called "Dillo Dirt" (as in armadillo).
 This popular product is sold to commercial vendors for sale and use in
public landscaping projects across the city. Demand for "Dillo Dirt"
often exceeds available supply.

During the 1980s, an initial effort to improve
energy efficiency at the plant started when two 400-kW converted diesel
generators were installed. The generators were fueled by a mixture of
digester biogas from the site and diesel fuel. This worked fairly well,
but after 20+ years the old generators are no longer serviceable or
repairable, and in recent years the gas has had to be flared. Austin
decided to use $1.2 million of its Energy Efficiency and Conservation
Block Grant from the American Recovery and Reinvestment Act of 2009 to
replace the old equipment with modern "biogas-rated" generation
equipment. Read the full story on DOE's Energy Blog.

New Thermal Window Technology Lessens Menace of Jack Frost

By Roland Risser, program manager, Building Technologies Program

Say what you want about the joys of Jack Frost
nipping at your nose, but when it comes to winter wonderlands, I like
mine outdoors. Etching icy messages on the insides of my windows is not
exactly cozy. Therefore, I'm thankful for technology that provides an
efficient and effective barrier from inclement weather.

Traco, a division of Kawneer and window
manufacturer since the early 1940s, recently partnered with the DOE's
Office of Energy Efficiency and Renewable Energy to utilize funds from
the American Recovery and Reinvestment Act of 2009 to develop new window
 technology. These OptiQ™ Ultra Thermal Windows can reduce energy loss
by up to 40% compared to the efficient, commercially available
double-pane low-emissivity windows that are already on the market.

Each year, windows account for an estimated 4
quadrillion British thermal units (Btu) of energy lost in U.S.
buildings, totaling over $35 billion in heating and air conditioning
costs. Future window systems like the OptiQ™ Ultra Thermal Windows will
eventually outperform the best-insulated walls or roofs in terms of
annual energy performance, peak demand reduction, and costs. This new
innovation holds promise to boost both savings and comfort. Read the full story on DOE's Energy Blog.
