ScienceDirect - Renewable and Sustainable Energy Reviews : Life cycle inventory analysis of the production of metals used in photovoltaics - 0 views

  • Material flows and emissions in all the stages of production of zinc, copper, aluminum, cadmium, indium, germanium, gallium, selenium, tellurium, and molybdenum were investigated. These metals are used selectively in the manufacture of solar cells, and emission and energy factors in their production are used in the life cycle analysis (LCA) of photovoltaics. Significant changes have occurred in the production and associated emissions for these metals over the last 10 years, which are not described in the LCA databases. Furthermore, emission and energy factors for several of the by-products of the base metal production were lacking. This review article aims in updating the life cycle inventories associated with the production of the base metals (Zn, Cu), and defining the production paths and emission and energy allocations for the minor metals (Cd, Ge, In, Mo, Se, and Te) used in photovoltaics.

EU greenhouse gas emissions fall for third consecutive year - All press releases - EEA - 0 views

  • European Union emissions of climate-changing greenhouse gases (GHG) declined for the third consecutive year in 2007, according to the EU's GHG inventory report compiled by the European Environment Agency. The EU-27's overall domestic emissions were 9.3 % below 1990 levels, which equalled a drop of 1.2 % or 59 million tonnes of CO2 equivalent compared to 2006. The EU-15 now stands 5 % below its Kyoto Protocol base year levels.

Opinion | Nuclear cleanup regulation could put public at risk | Seattle Times Newspaper - 0 views

    "The weaknesses of federal regulatory agencies have been exposed by recent high-profile accidents. Guest columnist Tom Carpenter fears the Department of Energy will reduce its oversight of cleanup at the nation's nuclear waste sites. By Tom Carpenter Special to The Times PREV of NEXT Related Millions of gallons of oil gush continue to rush unabated from BP's mile-deep well in the Gulf of Mexico, and 11 workers are dead from the massive explosion that caused the biggest oil spill in decades. Weeks before this event, the news was dominated by the preventable explosion that killed 29 West Virginia coal miners. In both cases, the not-so surprising news was that the mine and the oil rig had abysmal records of safety violations before the explosions yet were still allowed to operate by the captive regulatory agencies. Where is the government accountability? It is the government's job to assure that ultra-hazardous industries operate safely and responsibly. Is nuclear next? The Department of Energy sits on the nation's biggest nuclear nightmare. Its inventories of highly radioactive and toxic wastes defy comprehension. Washingtonians are familiar with the DOE's No. 1 accomplishment, the Hanford nuclear site, which holds the lion's share of the nation's radioactive detritus. Suffice it to say that the escape of even a small fraction of such material into the environment would constitute a Chernobyl-sized catastrophe."

    "Understanding the carbon balance of a business is a vital first step towards thinking about management decisions that may have some mitigating effect on climate change by reducing GHG emissions. The calculator has been updated with the latest UK National Inventory Report (1990-2006) data published in April 2009. This may change the output from previously entered data. Working through the steps below will help you calculate your carbon balance and understand the results. Step 1 - Get your data together. You will need physical data for crops, stock and energy use. Step 2 - Log-in (on menu bar) to enter your farm details or if you have previously used the calculator select a farm profile that has already been created by clicking on it. Step 3 - Create a calculation for the farm selected. If you have already created calculations for the farm selected you may also modify, copy or use any of these, also by clicking on the description. Step 4 - Enter data in the input screen. For more guidance visit the Help page. Step 5 - When finished obtain your CALM report by clicking "Report" at the top of the screen and choosing the output format you require. Step 6 - Use the mitigation advisory notes, available from the reports section, to assess ways you can improve your carbon balance."

Energy Outlook - 0 views

  • many reasons why oil prices have increased so dramatically, compared to their level prior to 2004. It's a long list, including the shift in power from commercial oil companies to national oil companies, and from non-OPEC producers to OPEC, geopolitical tensions, the growth of Asia, inventory, speculation, and even the lagged impact of the late 1990s oil price collapse.
