Saul Griffith, “Climate Change Recalculated” (MP3 audio), Longnow Foundation, 2009/01/16

Part of sustainability is conservation, but we can maintain even a minimal level of modern conveniences through conservation?

… the land area dedicated to renewable energy (”Renewistan”) would occupy a space about the size of Australia to keep the carbon dioxide level at 450 ppm. To get to Hanson’s goal of 350 ppm of carbon dioxide, fossil fuel burning would have to be cut to ZERO, which means another 3 terawatts would have to come from renewables, expanding the size of Renewistan further by 26 percent.

Meanwhile for individuals, to stay at the world’s energy budget at 16 terawatts, while many of the poorest in the world might raise their standard of living to 2,200 watts, everyone now above that level would have to drop down to it. Griffith determined that most of his energy use was coming from air travel, car travel, and the embodied energy of his stuff, along with his diet. Now he drives the speed limit (and he has passed no one in six months), seldom flies, eats meat only once a week, bikes a lot, and buys almost nothing. He’s healthier, eats better, has more time with his family, and the stuff he has he cherishes.

    On Android Oreo tablet, reference links on my PDF book don’t show up via Adobe Acrobat nor Google PDF Reader.  Links show up with qPDF Viewer, Foxit PDF Reader & Editor, and Xodo PDF Reader & Editor.  Presumption of basic functionality by bigger names is untrue. Advertisements
