• Biofuels May Be Threat To Food Supply, Increase Costs

    PARIS (Reuters) - Biofuels, championed for reducing energy reliance, boosting farm revenues and helping fight climate change, may in fact hurt the environment and push up food prices, one study suggested on Tuesday. In a report on the impact of biofuels, the Organization for Economic Cooperation and Development (OECD) said biofuels may "offer a cure that is worse than the disease they seek to heal". "The current push to expand the use of biofuels is creating unsustainable tensions that will disrupt markets without generating significant environmental benefits," the OECD said. >> Read the Full Article
  • Light-Emitting Diodes: Chasing White Light

    Light-emitting diodes (LEDs) use semi-conducting materials to turn electricity into light; electrons jump from one material to another, emitting photons as they travel. Different semiconductor materials create different colors of light: most white LEDs use indium gallium nitride (InGaN), which actually emits blue light. The blue light excites a phosphor coating on the lens of the diode, creating a yellow light that mixes with the blue and makes it look white to the human eye. Manufacturers also use closely placed red, green, and blue LEDs to deliver white light. >> Read the Full Article
  • Nuclear Industry Inches Toward New Construction In US

    SPRING CITY, Tennessee (Reuters) - When the Watts Bar Unit One here switched on in 1996 after a 23-year construction ordeal, it was the last of a generation of U.S. commercial nuclear power plants to emerge from a building cycle marred by massive cost over-runs and canceled plant orders. Now, the U.S. nuclear industry is hoping that its troubled building history will not repeat itself as it takes baby steps toward ending a 30-year nuclear construction hiatus. >> Read the Full Article
  • US Airlines Don't Want To Play By EU Emissions Rules

    BRUSSELS (Reuters) - A European Parliament committee sought on Tuesday to delay the inclusion of all airlines in the European Union's emissions trading scheme to 2012. The executive European Commission proposed last year that inter-EU flights be included in the EU scheme, aimed at reducing greenhouse gas emissions, from 2011, while international flights into and out of the bloc should be included from 2012. >> Read the Full Article

  • APEC Climate Goals: Talk, But Not Much More

    If the world’s leaders had an easy fix for climate change they’d probably embrace it. But they don’t have one. No one does. What leaders do have is fear of what they think would happen in the near term to the world’s economies with the massive cut in greenhouse gases that’s needed now. (They don’t fear what will happen to the world in the long term when they’ve passed on and are forgotten; the two-thirds cut in polar bear population over the next fifty years according to the US Geological Survey, for instance. Short term thinking is not what political leadership is supposed to be about, is it? >> Read the Full Article

  • Power From Waves, Wave Energy Converter Launched In Oregon

    PORTLAND, Oregon - (See VIDEO) This high tech bouy generates power from wave action. It's called an AquaBuOY. And it's about to be towed to sea for further tests and refinement. The company has adopted a philosophy of "Kaizen", a Japanese word meaning "change for the better" or translating to English, a philosophy of "continual improvement". "The AquaBuOY is a floating buoy structure that converts the kinetic energy of the vertical motion of oncoming waves into clean electricity. The AquaBuOY is categorized as a point absorber, defined as having a small dimension in relation to the longer wave length in which it is operating. It utilizes a cylindrical buoy as the displacer and the reactor is a large water mass enclosed by a long vertical tube underneath the buoy," says Finavera Renewables CEO Jason Bak, whose company designed the technology. >> Read the Full Article
