Posted on Sustainabilitank.info on April 27th, 2008 [OPINION by Charlie Hall About His: Charlie Hall's Balloon Graph - Energy researcher Charlie Hall's balloon graph challenges the notion that alternative energy sources will provide a smooth transition to a post-fossil fuel society. Scale and energy return remain huge obstacles. Charlie Hall is one the best-known energy researchers you've never heard of. That's because he puts his effort into understanding whole energy systems such as human civilization rather than perfecting headline-grabbing energy panaceas such as corn ethanol. From the early 1980s onward Hall and his colleagues--some of them former students--have been warning that a society hooked on fossil fuels would find itself up against limits not easily breached--probably sooner rather than later. With the current boom in biofuels, wind, and solar, and even a revival in nuclear power, many people believe that a smooth transition to a post-fossil fuel economy is already a foregone conclusion. But a careful look at Charlie Hall's balloon graph tells a different and much more disconcerting story (1). (To view a larger version of the graph, click here.) First, let's look at the components of the chart. On the vertical axis we have energy return on investment (EROI) expressed as the ratio of energy output versus energy input for each energy source. (Hall, an ecologist by training, appears to have coined the term by adapting "yield per effort" concepts from fisheries.) It is not always obvious to modern industrial people that it takes energy to get energy. The more energy we spend on finding, extracting, refining, and transporting energy resources, the less we have for all the other activities of society. The horizontal axis of the graph represents quads or more precisely, quadrillion BTUs (British Thermal Units). The graph depicts energy use in the United States. But the principles it demonstrates apply to the world as a whole. The various colors put focus on the annual production totals and energy return of oil at different times. The sizes for all the balloons represent a very rough guide to the uncertainties in calculating EROI ranges. (As we shall see, even with these uncertainties there is a very large discernible gap between what we currently get from fossil fuels and what we can expect to get from alternatives.) Oil, which makes up the largest percentage of U.S. energy consumption today (40%), has shown a substantial increase in its total output even as its EROI has fallen. To see this on the graph look at the blue balloon labeled "Domestic Oil 1930," the purple balloons labeled "Imported Oil 1970" and "Domestic Oil 1970" and the red balloons labeled "Domestic Oil Today" and "Imported Oil Today." That same move to a lower EROI is also being seen for natural gas and coal though the balloon graph does not depict these trends. Everyone knows that at some point fossil fuel supplies, which are finite, will begin to decline. To replace them we currently have biofuels such as biodiesel; other renewables such as wind, photovoltaic, and hydroelectric; and nuclear power. Oil from tar sands is also shown in the lower left-hand corner, but you have to look hard. And, that's just the point. You have to look pretty hard to see these alternatives on the graph. There are two reasons for this. First, some of these new sources are not very far along in their deployment. As they are more widely deployed, they will supply more total power and move to the right on the graph. Second, the EROI for biofuels such as biodiesel and for unconventional oil such as that extracted from tar sands is extremely low. Given current technology, these alternatives are not likely to move upward very much on the graph anytime soon. Hall believes we have two problems illustrated by his balloon chart. First, in order for these alternative sources to move rightward on the graph--that is, produce much larger quantities of energy for society--they will have to be deployed on a vast scale which few people contemplate or understand. Two examples come to mind. The worldwide installed capacity of solar photovoltaic cells is 10.9 gigawatts. With the total worldwide installed electrical generating base at 3,872 gigawatts, it would take more than 2,000 years at the current rate of installation (1.74 gigawatts/year) to reach today's capacity. And that's without even considering future growth in electricity demand. If we include the installed base of wind (74.3 gigawatts) and the current rate of wind installations (14.9 gigawatts/year), we can bring the figure all the way down to about 230 years, again without considering growth in demand. Of course, the rates of installation will grow, and there are other renewable and nonrenewable energy sources available. But the challenge of scale remains huge. When it comes to biofuels, the scale problem gets no better. Biofuels researcher Tad Patzek uses corn ethanol as an example. To fuel the American vehicle fleet using corn ethanol: (It’s important to note that nearly all the good sites for hydro power in the world have already been taken. And, turning to firewood for fuel would simply result in the leveling of the world’s remaining forests, leaving us with nothing for the future and destroying the habitability of the planet in the bargain. The upshot: Neither of these alternatives is going to move much to the right on the graph.) Many are saying peak world oil production will soon be upon us with peak natural gas and coal following close behind. To live anything like we now live, we are going to have to see some astounding technical breakthroughs in alternative energy sources soon. And those breakthroughs will have to be followed by dramatic and costly efforts to deploy alternatives rapidly and ubiquitously. For now we appear to be on a course that will require drastic changes in the way we live. Perhaps we will somehow muddle through. But when you look at Charlie Hall’s balloon graph, it’s easy to conclude that even muddling through might end up being a very unpleasant affair. Notes: (1) Hall, C.A.S., R. Powers and W. Schoenberg.

Renewable Energy Systems: Environmental and Energetic Issues. —————————————— We Posted the above without being in full agreement with what it says – not because what it says – but rather because what it does not say. What it does not say is the fact that nobody in his right state of mind will imply that one switches from oil into a different source of energy without first reducing needs for energy inputs to more manageable needs. First deal with conservation and avoid waste – that is the rule of the thumb! After you do this – only then – you figure what energy source is best suited to a particular need – and you go for it. What this will do – is simple – it will eliminate the anti biofuels arguments that were put forward by Professor David Pimentel already over 30 years ago. The world has changed since, but not Professor Pimentel’s ideas. In those days he went all out to lead the US Department of Energy away from the logical solution of using ethanol for the purpose of increasing octane value of gasoline when switching to unleaded gasoline. Those days Professor Pimentel was plainly trying to prop up the Mobil Oil Company’s opposition to a mandatory use of ethanol – a product that they were not in the business of making it available to the US economy. It was then Senator McGovern who got the scoop on Professor Pimentel – it is all in Congressional records. Pity that Charlie Hall is relying on the Pimentel input to something that otherwise could be viewed as a tool for policy analysis. His blog - http://scitizen.com/screens/blogPage/vie… has in it, at this time, also 15 reactions/comments to his posting. We hope that someday he might indeed converge his analysis with material available from other general policy analysts. We also would like to hope that Tad Patzek mentioned by Charlie can also enlarge the scope of his analysis. ### |

Posted on Sustainabilitank.info on April 27th, 2008 THE OIL POSTER: A Brilliant Tool for Examining the Geologic Realities and Social Ramifications of the Modern World’s Most Prized Resource. “If a picture is worth one thousand words, then The Oil Age Poster is worth one million words because people can not only see the oil production Hubbert’s peaks in many countries and regions, but also read the facts proving that global peak oil is both inevitable and quite probably imminent.” - U.S. Congressman R. Bartlett Colorful and authoritative, this poster traces the history of the Oil Age from its beginnings in the hills of western Pennsylvania in 1859 to its rise as the engine of global industrial economies. The poster’s main chart features a year-by-year rendering of worldwide oil production from 1859 to 2050 with projections of future production based on Colin Campbell’s Oil Depletion Model. Historical annotations as well as detailed data on production, trade and reserves make this poster a versatile tool for presenting the realities and implications of global oil production and its impending peak. (Size: 36″ wide by 24″ tall; Retail Price: $12.50) Buy a Poster from http://www.oilposter.org
Increasing Awareness - The primary goal of The Oil Age poster is to increase awareness of the critical role of oil in modern industrial society and to call attention to the impending worldwide peak in oil production. Benefiting Schools - Sales will help fund the no-cost distribution of The Oil Age poster to high schools, colleges and non-profit institutions. Proceeds will also support the development of teaching guides and other educational tools to be used in conjunction with the poster in classrooms. (View the list of teachers and schools who have been sent posters.) Benefiting Global Public Media - A portion of each sale will be donated to the non-profit Meta Foundation for the support of its projects and subsidiary non-profit organizations, including Global Public Media and the Post Carbon Institute. What the Experts Are Saying: “As this poster makes abundantly clear, we’ve already consumed about half of the world’s total endowment of regular conventional oil,” said Dr. Campbell. “This has provided most supply to-date and will dominate all supply far into the future. Now entering the second half of the Oil Age, we face the relentless decline of production, imposed by nature.” - Dr. Colin Campbell “This poster conveys a wealth of carefully researched information about oil depletion in a graphic format that anyone can quickly grasp. It is a map of our recent petroleum past and a glimpse into our post-peak future. No library, office or home should be without it!” - Richard Heinberg “The primary goal of The Oil Age poster is to increase awareness of the critical role of oil in modern industrial society, and to call attention to the impending worldwide peak in oil production.” ### |

Posted on Sustainabilitank.info on March 26th, 2008 China’s Fuel Efficiency Kicks America’s Butt - writes Dr. Joseph Romm, Climate Progress, March 25, 2008. The Toronto Star reported an alarming factoid earlier this month: No gasoline-powered car assembled in North America would meet China’s current fuel-efficiency standard. That’s mainly because: Their standard is much higher than ours is currently. Oh, and by 2010, China will be the world leader in wind turbine manufacturing and solar photovoltaics manufacturing. No worries, though, our TV and movie sales overseas still kick butt. For now. Tagged as: fuel efficiency, cafe, global warming, china, climate change ### |

Posted on Sustainabilitank.info on January 20th, 2008 The following was presented at the COP 10 of the UNFCCC in Buenos Aires in December 2004. It was prepared by a group of Japanese scientists from the Kyoto University, based on proposals that were put forward earlier by the Brazilian delegation to UN Framework Convention on Climate Change. The Japanese calculation uses a formula based on “regional Temperature Change Contributions (TCC)” that are the basis for climate change. The allowances per region, for future emissions, take into consideration the historical TCCs for the various regions. We believe that the attached graph will be part of the Japanese propsal for the G8 this coming May, so this is why we post it at this time. It is still possible to activate this sort of program starting 2013 for limits to CO2 emissions, in order to stabilize eventually the emissions at 450ppm, as it is suggested in the IPCC studies. ### |

Posted on Sustainabilitank.info on June 4th, 2007 To commemorate the World Environment Day on June 5, 2007: and LAUNCHES OF GLOBAL OUTLOOK FOR ICE AND SNOW report, UNEP/GRID Sioux Falls, has released a set of PowerPoint presentations entitled Melting Glaciers. Since 1960, glaciers around the world have lost an estimated 8 000 cubic kilometres of ice. There is now a consensus among many scientists that climate change is the “biggest crisis in today’s world” with the potential to cause catastrophic damage. This collection of visually compelling slides of melting ice, showing changes measured using satellite observations, is startling evidence of impact of rapidly changing climate. To download the presentation go to: http://www.na.unep.net/ and click on “Recent Releases” The presentation slides can also be downloaded from: ftp://na.unep.net/UNEP/TGiri/ ——————————————————————————– ### |
