| Secretary Chu Announces Major New Recovery Act Milestone: 300,000 Homes Weatherized
U.S. Department of Energy Secretary Steven Chu today announced that states and territories across the country have now weatherized more than 300,000 low-income homes under the Recovery Act, a major milestone in the Department’s efforts to reduce home energy bills for families. This means that states are now more than 50 percent of the way toward meeting President Obama’s goal of weatherizing approximately 600,000 homes under the Recovery Act. The weatherization program is helping families save money on their energy bills by improving home energy efficiency with upgrades like insulation, air-sealing, and more efficient heating and cooling systems. The program has also trained a new generation of clean energy workers and is employing more than 15,000 workers nationwide. “Today marks a major milestone for the weatherization program and shows once again that we are on pace to meet the goals of the Recovery Act. This program has already benefitted 300,000 low-income families and put thousands of people to work,” said Secretary Chu. “Through the weatherization program, we are laying the groundwork for a broader efficiency industry in the U.S. that will help grow our economy while saving money for American families.” Through November, the network of state offices, local agencies, and weatherization providers has completed 300,000 homes. Of the total, more than 100,000 have been completed in just the last four months, showing the dramatically accelerated pace of weatherization under the program. A state-by-state breakdown of the homes weatherized through November is available at http://www.energy.gov/recovery/energyefficiency.htm. Weatherization assistance reduces energy consumption for low-income families on average 35 percent, saving families on average more than $400 on their heating and cool bills in the first year alone. Nationwide, the weatherization of 300,000 homes is estimated to save $161 million in energy costs in just the first year. DOE has worked closely with state and local governments to ensure the program is well-managed, responsive, and flexible. Nearly all of the states and territories involved in the program have met the milestone of weatherizing more than 30 percent of their targeted number of homes and many have completed more than half of their goals to date.
__________ Homes Weatherized by State The Department of Energy is collecting monthly data from the states on the number of homes weatherized under the Recovery Act. The below spreadsheets shows figures for homes weatherized (1) in April 2010, and (2) in the first quarter of 2010 (January-March). In March, the weatherization network nationally reached their target run-rate and weatherized more than 25,000 homes across the country. Since the Recovery Act began, states have used their Recovery Act funding and annual program funds to weatherize more than 193,000 homes.
This is an end-of-the-year report on the number of homes weatherized by state as part of the Weatherization Assistance Program during calendar year 2009. This data was reported by states and may be updated as states finalize figures for homes weatherized through December 31st. By the end of 2009, states weatherized more than 125,000 homes with Recovery Act and non-Recovery Act annual federal funding. Since the Recovery Act funding allowed states to accelerate their existing programs with Fiscal Year 2009 funding, the combined total is the best indicator of progress in the program. Nevertheless, the pace of Recovery Act-funded weatherization tripled in the last three months of the year. -=-=-=-=-=-=-=-=-=- email Scotts Contracting to schedule a Home Weatherization Inspection.

Researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and the University of Colorado, Boulder (UCB), have reported the first designed molecular system that produces two triplet states from an excited singlet state of a molecule, with essentially perfect efficiency.
The breakthrough could lead to a 35 percent increase in light-harvesting yield in cells for photovoltaics and solar fuels.
The experiments, using a process called singlet fission, demonstrated a 200 percent quantum yield for the creation of two triplets of the molecule 1,3-diphenylisobenzofuran (DPIBF) at low temperatures.
In singlet fission, a light-absorbing molecular chromophore shares its energy with a nearby non-excited neighboring molecule to yield a triplet excited state of each. If the two triplets behave independently, two electron-hole pairs can be generated for each photon absorbed in a solar cell. This process could subsequently increase by one third.the conversion efficiency of solar photons into electricity or solar fuels.
The researchers identified DPIBF as a promising candidate while searching for molecular chromophores that have the required ratio of singlet and triplet energy states.
Earlier, NREL and Los Alamos National Laboaratory had demonstrated an analgous two-electrons-from-one photon bonus using semiconductor quantum dots in a process NREL termed Multiple Exciton Generation. The latest advance is the first to demonstrate the electron multiplication phenomenon via the singlet-fission process in molecules.
Until this most recent advance, singlet fission had been known as a somewhat obscure phenomenon occurring at low efficiency in a small number of molecular systems. In 2004, NREL and UCB revisited singlet fission as a potential way to maximize solar photon conversion efficiency. In 2006, NREL’s Arthur J. Nozik and Mark C. Hanna calculated the gains in thermodynamic efficiencies that were possible with solar cells based on singlet fission. These activities led to a much more extensive search for the best candidate molecules in a collaboration between NREL and the research group at the UCB led by Josef Michl.
The research has been published in the Journal of the American Chemical Society. Authors are NREL’s Justin C. Johnson and Arthur J. Nozik, and UCB’s Josef Michl. For a technical summary of this article, please visit http://www.nrel.gov/news/pdfs/technical_summary_20101202_press_release.pdf![]()
