    VSOUKOLOHLOR: no, teda nemyslím, že být "bright-green" znamená být nutně "projaderný". (viz ostatně i definice pojmu na wiki, apod.)

    je to obecně víra, že existují technologická řešení problémů, které technologie způsobily, nebo spíš že si lze představit alternativní technologie k těm dnešním, apod. - podle mě ale ne nutně každý, kdo se pokládá za bright-green, nějak zvlášť sází na jadernou energii (příkladem můžu být například já).

    Vida, zde něco k současným krizím ve Španělsku a Portugalsku:

    But my sour feelings don't come just from a frustrating conference. My country (=Portugal) has had its Peak Oil moment and is now undergoing a self destruction process. Energy consumption is declining to levels of 15 or 20 years ago, with most mechanisms put in place for the energy transition being rolled back one after the other. As founding member of ASPO-Portugal, I can only take this as failure. It was precisely to avoid this kind of scenario that I started working on Peak Oil in 2005. But here we are; the efforts of the handful of people backing up our association are now largely irrelevant. The media and the politicians who once showed interest on the subject are gone, and so are we; sadly I'm not the only exiled member of ASPO-Portugal. Long gone seem the days when the Depletion Protocol was discussed and recommended by Parliament. Looking back, I can only acknowledge that I was delusional in thinking I could change anything.

    My friends from ASPO-Spain tell a similar story - a 10-year regression in energy consumption, with the deliberate slow-down of economic activity. Unfortunately, the role oil, coal and food prices had (and still have) in the economic crisis is not acknowledged by everyone, not even within ASPO. This is a terrible mistake, for this is exactly what Peak Oil looks like. Getting ourselves intertwined in the debt or peak demand discourse is a self defeating path that will veer policy makers away from addressing the structural weaknesses of our economies. It is never too much to remember that the states today cut off from the European sovereign debt market are precisely those that were most dependent on oil before the crisis.

    Prečo veľa ľudí to, o čom hovoríte, ignoruje?

    Mnohí z nevedomosti a zvyšok zo strachu. To, čo hovorím, skutočne v mnohých vyvoláva strach z neznámeho. Ľudský mozog je stroj na vieru. Dokáže uveriť tým najabsurdnejším výmyslom a úplne vytesniť nepríjemné fakty. Tento mechanizmus sa volá denial – popieranie reality – a bránime sa ním proti všetkým zlým správam, napríklad keď ochorieme na vážnu chorobu. Dnes je vážne chorá celá naša civilizácia. Liečba bude dlhá, bolestivá a výsledok je neistý. Po fáze popierania prichádza fáza hnevu – to sú tí nadávajúci čitatelia. Po nej fáza dohadovania sa, to sú čitatelia, ktorí napríklad veria, že miliardu áut so spaľovacím motorom nahradíme po ropnom zlome ľahko miliardou elektrických áut, a nepýtajú sa za čo. Nasleduje fáza depresie, keď analýzou zistíme, že máme naozaj veľmi vážny problém. Až potom prichádza fáza akceptácie, keď sa začíname na budúcnosť pripravovať. Väčšina Slovenska vrátane politikov je dnes stále vo fáze sladkej nevedomosti, prípadne popierania.

    A velmi pěkně na to reaguje Heinberg:

    Peak Denial | Energy Bulletin
    http://energybulletin.net/stories/2012-07-02/peak-denial

    ...

    The recent deluge of cornucopian triumphalism has provoked a few thoughtful responses, including, “Has Peak Oil Idea . . . Peaked?” and “Is Peak Oil Dead?”, both of which carefully sift the evidence and conclude that world oil production is better understood when viewed through the depletionist lens than through the rose-colored glasses of the Peak Oil naysayers.

    ...

    The Peak Oil debate is not a sporting event. What matters is not which side wins, but what reality awaits us. Will we see a continuing plateau in global crude oil production? How long will it last? How big a proportional contribution to total liquids production will we see from tar sands, shale, and other unconventionals? What will be the climate impact as the world’s petroleum supply is increasingly derived from lower-grade resources? And what will be the economic impact?

    We at Post Carbon Institute hope to sort out some of the technical issues related to unconventional oil in a report (forthcoming in September) by David Hughes, a follow-up to his 2011 reality check on U.S. shale gas production. But the bigger environmental and economic questions will no doubt continue to generate uncertainties for some time.

    ...

    As many peakists have been saying all along, we’ll know for sure precisely when global oil production peaks (in terms of rate of production in barrels per day) only when we can see a steady decline in the rear-view mirror. But by then it will be too late for society to prepare for the economic impacts of Peak Oil. So is the Peak Oil “movement”—not as an exercise in analysis, but as an effort to warn the world and prevent catastrophe—doomed to failure? Maybe. But by the same token so is most of, if not the entire, environmental movement. We will not substantially change our collective behavior until crisis is upon us.

    But even if we cannot avert a crisis, we can prepare some portion of the populace for the aftermath. We can build community resilience. We can seed the public conversation with information that will undermine the inevitable, reflexive effort to blame economic unraveling on handy scapegoats. Also, the future will be better if we protect at least some species, some habitat, some wild places, some water, and some topsoil before the energy-led crash of the economy, so that we have an ecological basis for ongoing existence in the absence of cars, planes, iPads, and cheap, abundant fuel.

    SCHWEPZ: Pod článkem jsou věru pěkné komentáře, takže pro zopakování:

    Není to žádná studie
    ... je to PR exekutivce italské ropné společnosti Eni (v článku ho vtipně nazývají "americkým výzkumníkem"). Vzděláním je to ekonom, nikoliv geolog, takže jeho závěry patří spíše do říše fantazie (schválně se za domácí úkol podívejte, jaké byly prognózy IEA a CERA pro svět z roku 2000). Klíčová je tato věta z Wikipedie:

    "In the Republic of the Congo, the Italian oil company Eni have announced in May 2008 a project to develop the small oil sands deposit in order to produce 40,000 barrels per day (6,400 m3/d) in 2014"

    Čili pán je na všem osobně zainteresovaný.

    Ropné písky se samozřejmě těží, ale opět za domácí úkol si dohledejte, kolik dělá denní produkce celé Kanady - údaje z roku 2006, jsou něco přes 1,2 milionů barelů denně. Kolik spotřebuje denně Amerika? Téměř 19 miliónů barelů denně. Víc jak polovinu z toho stále dováží. Přitom kanadská produkce se nedá jen tak škálovat - písky je třeba zahřávat na vysokou teplotu, takže se na místě stavějí jaderné elektrárny...

    ... navíc proces kontaminuje karcinogeny obrovské množství vody (osm barelů vody na jeden barel ropy), která vesele uniká z povrchových nádrží, kterou ropné společnosti slíbily "snad někdy" vyčistit. Kdo na místě byl, popisuje to přesně jako Mordor z Tolkienových knih - tam, kde byl dřív les, jsou jen haldy toxické strusky a odpadu.

    Ani energetická návratnost není nijak skvělá, takže abychom zůstali na stejném čistém energetickém zisku, je nutno produkovat mnohem větší objemy (protože záleží na čistém energetickém zisku, nikoliv na absolutním objemu produkce).

    Další fantazie se týkají ropných břidlic (oil shales), které jsou označovány jako kerogen - totiž organické pozůstatky dávných živočichů a rostlin, které je však nutno zahřát na vysokou teplotu (pyrolýza), aby se z nich dala získat syntetická ropa, takže velká část ložisek ve formaci Bakken vůbec není prakticky těžitelná, protože energetické náklady by převýšily zisk (jsou to resources, nikoliv reserves).

    A jaký je celkový objem těžby v Severní Dakotě po "novém ropném boomu", jak se to v tisku nazývá? Produkce stoupla z 80 tisíc barelů denně na cca 250 tisíc, čili 1/76 americké spotřeby.

    Amerika ve své současné podobě co se ropy týká soběstačná nikdy nebude. Proto musí ropu krást v dobyvačných válkách po celém světě.

    Learning from US Shale Gas Experience - Arthur Berman - YouTube

    Geological Consultant Arthur Berman explains to the ASPO 2012 conference his view that the "goid rush" period of shale gas in the US is over. As Art puts it "Once you start drilling shale wells you can never stop...shale plays are not a renaissance or a revolution, this is a retirement party."

    Last week, at a public meeting, I was asked several times if this famed "peak oil" has arrived or not. People who have heard of peak oil seem to be becoming impatient, but I am afraid we'll have to wait a little longer. Peak oil is not here yet, at least if we intend it as a significant decline in the production of combustible liquids. Does that mean that the predictions based on the Hubbert model were wrong? In a sense, yes: you should know that all models are wrong by definition. Some, however, can be useful if you know how to use them. That's the case of the Hubbert model: it had given us a useful warning that, however, we chose to ignore. Let me explain this point by means of a summary
    of a talk that I gave at the conference on the future of energy organized in Basel by the Club of Rome on 16-17 october 2011. A few months have passed since I gave that talk, but things haven't changed much from then.

    ...

    We don't see a peak for the year 2000, nor we see it for 2005. If the peak had been in 2000 or 2005, we should be already seeing a significant production decline. What we see, instead, is a plateau that has been lasting for the past five years or so, interrupting the growth trend that had been the rule from 1983. So, no peak so far, but clearly "something" has been happening with oil production starting with the first decade of the 21st century, considering also the remarkable increase in oil prices of that period. But what's happening, exactly? Where is the peak? Should we expect it soon, or is it delayed for a long time?

    I think that at this point we need to pause for a moment. What is exactly a model and what can it be used for? Models come in a variety of forms: formal, informal, complex, simple, aggregated, multiparameter and more. But, no matter what model you are using, one thing that can be said is that if you think it can predict the future, I am afraid that you are going to be sorely disappointed. Complex mathematical models may not be any better than the crystal ball that is part of the toolbox of any self respecting magician. Models are no magic. Models are just tools. And, just as with any tool, you need to know how to use them, otherwise you risk to hurt yourself.

    ...

    What should we expect now? Well, we don't need a formal model to understand that the oil industry can keep extracting oil as long as there are customers able to pay for it. The problem is that, with progressive of depletion, extraction costs can only increase as we tackle more and more difficult, dirty, and remote resources. That will be continue to generate high prices. So, we'll have peak oil when we won't be able to pay these prices any longer.

    A komentář: It is disappointing to read an article that indicates it is discussing peak oil and shows instead a graph that includes natural gas liquids. Why not show oil plus field condensate?
