The Department of Energy announced final furnace fan energy efficiency standards today, the one-year anniversary of the release of President Obama’s Climate Action Plan. “The part of the Climate Action Plan that got the most attention was the EPA rules on power plants,” but the plan was packed with smaller DOE measures that will add […]
The US House of Representatives passed two energy efficiency bills, one of which is to better assist schools with energy-efficient enhancements, and the other instructs the Department of Energy to research the effect of insulation on energy and water usage on federal buildings. The School Energy Efficiency Bill – H.R. 4092 This bill creates […]
The U.S. Department of Energy (DOE) launched June 11 a free, open-source, standard software application for the management of building performance data, the first such software of its kind. The Standard Energy Efficiency Data platform (SEED) can be used by city governments, researchers, utilities, and others to manage, validate, and share large amounts of data […]
Light-absorbing perovskite cells show promise as solar material Known as perovskite, the name of this material found in the Ural Mountains may be difficult to pronounce for American English speakers, but the potential it offers as a new solar dell material is considerable. Three scientific papers have already been published about it. Intense research efforts, […]
We have received the following press information from New Energy Technologies. concerning an update on the unveiling of their largest SolarWindow prototype now manufactured. According to a New Energy spokesperson, the device is “something we like to call a vertical power generator on any glass surface.” Imagine the ability to look out at the yard, […]
The Energy Department’s (DOE) National Renewable Energy Laboratory (NREL) recently issued a new report, “Non-Hardware (‘Soft’) Cost-Reduction Roadmap for Residential and Small Commercial Solar Photovoltaics, 2013,”PDF funded by DOE’s SunShot Initiative and written by NREL and Rocky Mountain Institute (RMI). The report builds off NREL’s ongoing soft-cost benchmarking analysis and charts a path to achieve […]
The presence of wind turbines and wind farms near residential properties has no effect on the value of said properties, according to new research from the Lawrence Berkeley National Laboratory (Berkeley Lab). The findings are the result of an analysis of the sales of more than 50,000 homes — located near 67 different wind energy […]
No matter who spins it, sustainable LEED construction has captured the attention of many people, impacting the design of everything from HVAC systems to building envelopes, from renewable energy use to LED (light-emitting diodes) lighting. LEED, or Leadership in Energy & Environmental Design, has significantly impacted thinking about how our buildings and communities are designed, […]
Guest Post: DOE Backs Down on Higher Furnace Efficiency Standards; Air Conditioning Standards also Being Challenged
In late 2011, the Department of Energy (DOE) announced increases in the minimum efficiency standards of residential furnaces and air conditioners. In the 30 northern states, the minimum efficiency rating of new furnaces was to be raised to 90 percent from its current level of 80 percent, starting May 31st, 2013. In the 20 southern states, the minimum efficiency of air conditioners is set to be raised from 13 SEER to 14 SEER starting January 1st, 2015 (SEER is the estimated BTU’s of cooling provided by each watt-hour of electricity, so a 14 SEER unit will use about 7 percent less energy than a 13 SEER system). These changes were expected to reduce greenhouse gas emissions by 113 to 143 million tons, and to reduce residential energy consumption by one-fifth.
Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.
[repostus]Student Teams Participating in the Solar Decathlon 2013 (via 1Sun4All) By Amber Archangel The U.S. Department of Energy Solar Decathlon challenges collegiate teams to design, build and operate solar-powered houses that are cost-effective, energy-efficient and attractive. The winner of the competition is the team that best blends affordability, consumer appeal and design…

Researchers from the Department of Energy’s Pacific Northwest National Laboratory will exhibit their work at the 2013 Energy Innovation Summit of high-impact energy research funded by DOE’s Advanced Research Projects Agency-Energy, or ARPA-E. The summit runs Feb. 25-27 at the Gaylord Convention Center in National Harbor, Md. Below is an overview of PNNL research that will be highlighted there.
A collaborative study by researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a bioenergy research center led by Berkeley Lab, and the Idaho National Laboratory (INL) has shown that an ionic liquid proven to be effective for pre-treating individual biofuel feedstocks is also effective at pre-treating multiple different feedstocks that have been mixed and densified into a blend.
