But how much gas is coming from the cows themselves? http://www.physorg.com/news173451276.html Space & Earth Tue, 29 Sep 2009 13:56:40 EST news173451276 I shaved 0.86 pounds of emissions from my carbon footprint and saved 0.646 kilowatt hours yesterday, and if the little widget on my PC can be believed, more than 22,000 people in 128 countries did roughly the same. http://www.physorg.com/news172916653.html Technology Wed, 23 Sep 2009 09:50:03 EST news172916653 MIT researchers have developed designs for a new kind of coal-burning power plant, called a pressurized oxy-fuel combustion system, whose carbon-dioxide emissions are concentrated and pressurized so that they can be injected into deep geological formations. This system is a way to reduce the energy penalty that all carbon-capture systems for power plants have compared to regular fossil-fuel plants, and could thus be an enabling technology to help make carbon capture and sequestration systems (CCS) practical and affordable. While all carbon capture systems incur about a one-third reduction in plant efficiency, this system reduces that penalty. http://www.physorg.com/news172754912.html Technology Mon, 21 Sep 2009 12:28:52 EST news172754912 An award-winning Los Alamos National Laboratory sound-wave technology is helping Solix Biofuels, Inc. optimize production of algae-based fuel in a cost-effective, scalable, and environmentally benign fashion -paving the way to lowering the carbon footprint of biofuel production. http://www.physorg.com/news171203048.html Technology Thu, 03 Sep 2009 13:40:04 EST news171203048 Some people who are serious about wanting to reduce their "carbon footprint" on the Earth have one choice available to them that may yield a large long-term benefit - have one less child. http://www.physorg.com/news168263826.html Space & Earth Fri, 31 Jul 2009 12:57:44 EST news168263826 In an effort to achieve energy-aware computing, the Swiss Federal Institute of Technology Zurich (ETH), and IBM today announced plans to build a first-of-a-kind water-cooled supercomputer that will directly repurpose excess heat for the university buildings.

For Manhattan, the goal is to reduce greenhouse gases 30% by 2017. As part of this effort, the New York City Police Department just added 40 hybrid cars to its fleet. The Nissan Altima Hybrids are the first NYPD alternative fuel patrol cars, but they probably won't be the last. The NYPD plans to deploy at least 100 hybrids in total this year. http://www.physorg.com/news160734148.html Technology Tue, 05 May 2009 09:22:58 EST news160734148 (AP) -- There are plenty of reasons to hate spammers.

Results from a new University of Missouri study suggest that some of the largely petroleum-based plastic may soon be replaced by a nonpolluting, renewable plastic made from plants. Reducing the carbon footprint and the dependence on foreign oil, this new 'green' alternative may also provide an additional cash crop for farmers. http://www.physorg.com/news153577260.html Chemistry Wed, 11 Feb 2009 12:21:49 EST news153577260 Publications ranging from the journal Science to Time magazine have blasted biofuels for significantly contributing to greenhouse gas emissions, calling into question the environmental benefits of making fuel from plant material. But a new analysis by Michigan State University scientists says these dire predictions are based on a set of assumptions that may not be correct. http://www.physorg.com/news151257863.html Space & Earth Thu, 15 Jan 2009 16:04:23 EST news151257863 A recent study shows that shade trees on the west and south sides of a house in California can reduce a homeowner's summertime electric bill by about $25.00 a year. The study, conducted last year on 460 single-family homes in Sacramento, is the first large-scale study to use utility billing data to show that trees can reduce energy consumption. http://www.physorg.com/news150384050.html Space & Earth Mon, 05 Jan 2009 13:20:50 EST news150384050 Carnegie Mellon University researchers are urging companies to embrace new methods for following the trail of dangerous carbon emissions that are responsible for much of the world's global warming threats. http://www.physorg.com/news138072347.html Space & Earth Sat, 16 Aug 2008 02:25:47 EST news138072347
