Supermarkets are among the most energy-intensive buildings around, and refrigeration uses more than half of that energy. That doesn't even include the harm that leaking refrigerants cause to the ozone layer. EPA's GreenChill program works with companies and their refrigeration engineers across the country to help program participants lower their refrigeration emissions of all kinds.
The prospect of limiting temperature rise to 2 degrees Celsius is looking bleaker, officials at the International Energy Agency said.
Identifying the human impact of rising sea levels is far more complex than just looking at coastal cities on a map. Rather, estimates that are based on current, static population data can greatly misrepresent the true extent – and the pronounced variability – of the human toll of climate change, said University of Wisconsin-Madison researchers.
According to a recent report from Pike Research, despite limited production to date, the scale-up potential of algae is substantial compared to other non-food based feedstocks.
A technical comment published in the current edition of the journal Science casts doubt on a widely publicized study that concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well.
Spurred by a desire to increase sales of fuel-efficient cars, The Environmental Protection Agency and Department of Transportation announced an overhaul of the fuel-efficiency labels affixed to windows of new cars starting in 2013.
A report from MIT and The University of Texas at Austin urges the United States to accelerate efforts to pursue carbon capture and storage in combination with enhanced oil recovery, a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide.
Computer simulation studies by scientists at the U.S. Department of Agriculture suggests that a dairy cow living year-round in the great outdoors may leave a markedly smaller ecological hoofprint than its more sheltered sisters.
GE unveiled its latest wind turbine technology, the 1.6-100, at the American Wind Energy Association’s (AWEA) Windpower 2011 Conference & Exhibition. The company has already secured nearly 630 megawatts of commitments for the evolutionary 1.6-100, which has been designed for increased performance in areas with lower wind resources
The once degraded forests in the Curacautin Valley in Chile have now recovered sufficiently, after hard work over the last decades, to be able to help provide a sustainable living to the people in the area, based on fair trade and responsible forest management principles.
The map provides detailed graphs and analysis of 40 social enterprises in 16 countries that are overcoming vast hurdles in their respective markets to bring electricity or alternative fuel to 500 to 500,000 people apiece.
Researchers in the college’s department of paper and bioprocess engineering are experimenting with different strains of bacteria that can ferment sugars extracted from wood into biobutanol that can be pumped into automobile gas tanks. They believe that biobutanol — more efficient than ethanol in producing energy and easier to add to the existing gasoline distribution infrastructure — could be the emerging biofuel of the future.
According to an article in Nature, researchers have spotted signs of recovery in the ozone hole above Antarctica. These first signs of human-caused shrinkage come 22 years after the Montreal Protocol, an international agreement that banned the use of ozone-depleting chloroflurocarbons.
The study details 12 technologies and 36 projects that convert wood to fuels including ethanol, butanol, diesel, gasoline, and jet fuel.
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) released its annual assessment of leading utility green power programs.
The American Physical Society has released a new assessment, titled “Direct Air Capture of CO2 with Chemicals,” to better inform the scientific community on the technical aspects of removing carbon dioxide from the atmosphere.
As concerns about air pollution from large dairies and other concentrated animal feeding operations (CAFOs) continue to mount, scientists are reporting a practice that could cut emissions of the abundant agricultural gas ammonia by up to 30 percent.
The presence of even a simple chemical reaction can delay or prevent the spreading of stored carbon dioxide in underground aquifers, new research from the University of Cambridge has revealed.
Oak Ridge Associated Universities (ORAU), a consortium of 98 doctorate-granting universities, has selected Rosenthal to receive the Ralph E. Powe Junior Faculty Enhancement Award to pursue the novel research. Rosenthal is one of 30 award winners nationwide.
The production of wind energy in the United States in the next 30 to 50 years will be largely unaffected by upward changes in global temperature, said a pair of scientists who analyzed output from several regional climate models to assess future wind patterns in America's lower 48 states.
