139 Countries Could Transition to 100% Renewable Energy Under New Plan - NBC News - 3 views

  • A team headed by Stanford’s Mark Z. Jacobson outlined plans for 139 nations to transition to 100 percent clean, renewable energy by the year 2050.
  • The shift would also allow the countries to avoid the 3 percent they now spend in their Gross Domestic Products to address the costs of air pollution — mainly in the form of higher health care spending.
  • The plan maps each country and the energy sources it would rely on to reach the 100 percent renewable goal. Water-bound and geologically active Iceland would get 28 percent of its power from hydroelectric sources and nearly 23 percent from geothermal. Parched and wide-open Australia would get nearly 45 percent of its power from wind farms. Poland would get nearly two-thirds of its power from the wind.

  • The paper envisions a world of rapid technological change and a shift in which electricity replaces coal, oil, and gas. Fully implemented, the plans anticipates that 57.6 percent of that electricity would come from solar, 37.1 percent from wind and the rest from a combination of hydroelectric, geothermal, tidal and wave energy.

    Great idea but appears somewhat dormant. It is hard to keep a volunteer group like this going. I speak from personal experience.

    Biodiesel is the product obtained when a vegetable oil or an
    animal fat reacts chemically with an alcohol to produce fatty acid
    alkyl esters. A catalyst such as sodium or potassium hydroxide is
    required. Glycerol is produced as a co-product (Van Gerpen et al.,
    2004). The most common stoichiometries description of the reaction
    is:
    1000 kg of oil þ 110 kg of methanol/1000 kg of biodiesel
    þ 110 kg of glycerol
