    Excerpt: ... e is eager to save money. In fact, Americans have pioneered a host of gas-saving tactics in the last 20 years. Without these moves, scientists at Lawrence Berkeley National Laboratory estimate, our national energy consumption would be about 50 percent higher. Beyond those successes, though, there's room for improvement in your home, car and workplace. Experts advanced solutions in three broad categories: simple steps that are a snap to accomplish; complex strategies that are worth thinking about; and iffy breakthroughs that, today at least, seem like a stretch. Home It's a success: Green leaves and appliances. Americans are great planters of trees, whose shady branches can lower temperatures and the cost of air conditioning in adjacent homes and office buildings. Moreover, the leaves can absorb up to 15 percent of greenhouse gas emissions. This is a love the world should share. "Can this be replicated in India and other countries? Sure," noted Jayant Sathaye, a scientist at Lawrence Berkeley National Lab ...

    Excerpt: ... High Accuracy Atomic Physics in Astronomy, IP/ITAMP workshop, August 7-9, 2006, The Harvard-Smithsonian Center for Astrophysics, Cambridge, MA, in honor of Prof. Micheal J. Seaton Solid State Astrophysics : Present & Future Prospects Julia C. Lee The Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA Email: jclee@cfa.harvard.edu X-ray observations of astrophysical plasma, given high enough spectral resolution and thoroughput should allow us to directly probe the chemical composition of astrophysical dust grains. Our present best prospects, for Fe-based grains, have gone with the demise of the XRS on Suzaku. Based on low energy laboratory studies of grain candidates at the Lawrence Berkeley National Laboratory Advanced Light Source, I discuss prospects for doing such studies in the soft ( 5 keV) band with extant space-based X-ray instruments such as the Chandra HETGS and XMM-Newton RGS. The requirements of satellite spectral specications will also be disc ...

    Excerpt: ... Hydrogen Adsorption of Single-Walled Carbon Nanotubes Studied by Soft-X-Ray Spectroscopy Jinghua Guo Lawrence Berkeley National Laboratory, 1 Cyclotron Road, Berkeley, CA 94720 The storage of hydrogen in a both safe and compact manner is of great importance for, for example, hydrogen powered vehicles. Interesting candidates for dense storage of hydrogen include different types of carbon based nanomaterials: Single-walled carbon nanotubes (SWNT), multi-walled carbon nanotubes and graphene layers. SWNT for hydrogen storage becomes a subject of active research. Different mechanisms for interaction of H2 and SWNTs were reported. Highly ordered pyrolytic graphite (HOPG) has similarities with the carbon systems mentioned above. Photon-in, photon-out soft-xray spectroscopies are well suited for measurements of the electronic structure of these materials under ambient hydrogen pressure. X-ray absorption (XAS) and emission spectroscopy (XES) measurements have been performed on SWNTs and HOPG under different hydrogen p ...

    ethanol

    Iowa State, MR 0525

    Excerpt: ... Auto Industry, UK 05-21-07 California seeks end to domestic ethanol production subsidies California Gov. Arnold Schwarzenegger said on 18 May a symposium on low carbon fuels at the Lawrence Berkeley National Laboratory in Berkeley, Ca. that he wanted markets to set policies on low carbon fuels, and called for eliminating subsidies and tariffs related to ethanol. California is due imminently to release environmental rankings for gasoline and all available alternative fuels, including ethanol. The United States, said Governor Schwarzenegger, subsidises domestic cornbased ethanol by 51 cents per gallon while imposing an import tariff of 54 cents per gallon on ethanol imports from Brazil. The recent boom in US ethanol production has increased maize prices and in turn, livestock feed costs for farmers. One result, according to a recent study by Iowa State University, has been a US$47-per-capita increase since last July in the average US grocery bill. A proposal by the House of Congress's Agriculture Committee last ...

    Appendix E

    UCSB, ESM 595

    Excerpt: ... APPENDIX E ESTIMATION OF CONSUMER INVESTMENTS AND SAVINGS UNDER THE HIGH EFFICIENCY/CARBON LEVEL OF 515 MMT IN 2008 CASE EPA estimated the investment costs and savings under the High Efficiency/ Carbon Level of 515 MMT in 2008 case by using unpublished information from the Lawrence Berkeley National Laboratory and U.S. Environmental Protection Agency entitled Technology and Greenhouse Gas Emissions: An Integrated Scenario Analysis Using the LBNL-NEMS Model, September 1998. This joint LBNL/EPA study has examined this option for lowering greenhouse gas emissions. The information that EPA used provides estimates of the annualized capital investment that the residential, commercial, and industrial sectors make to lower electricity use. The study also provides estimates of the electricity savings, and the value of those savings. The joint LBNL/EPA study showed that for every MWh of electricity savings in 2010 there is $22.42 of annualized dollar investment and $35.36 in annual electricity bill savings in 1990 doll ...
