Petroleum, Mining, and Logging Industries
Business thrives in creating demand or making it appear that there is scarcity in supply. That said, it is for their benefit to paint a gloomy picture of the fuel supply and get richer many times over than if they just kept on silently producing.
On the issue of whether the peak oil has been reached or not, nobody on earth can exactly predict the exact year. See it here. What are the real numbers? Quote:

The best proof of this can be seen in your first point. With high oil prices, companies should be ramping up production right now to meet increasing demand from BRIC. This is also seen in the recent BP report which shows energy demand higher than production from conventional sources. But SA, which insisted that it would be able to breach 100 mb/d, barely reached 90 mb/d. Now, their production costs have gone up to at least $75 per barrel. Ironically, more proof can be seen in the very article mentioned, which refers to questionable theories like abiogenic oil as well as the use of synthetic oil, which was tried in the past. In general, references to non-conventional sources of energy to replace "easy oil" is the best evidence for peak oil, and also negates claims that oil companies are hiding something. In addition, the latest BP report shows that increasing energy demand is now being met by the same non-conventional sources of energy, particularly biofuels, which not only contribute to food prices but are also shown to have lower EROEIs than what they are replacing. Other errors: claims of numbers of barrels refer to what is technically recoverable, which is always several times higher than what is eventually extracted. Quote:

Finally, at best adapting will very likely mean localization and using whatever resources are available to meet basic needs. Incredibly resource- and energy-hungry things like a middle class lifestyle (e.g., condo unit or houses, passenger vehicles, computers, cell phones, and other appliances and electronic gadgets, air travel, processed food available in supermarkets, and in general a JIT system) will not be sustainable. As the IEA points out, just to maintain current economic growth, we will need the equivalent of one SA every seven years. And with growing middle classes in BRIC and emerging markets, even more resources will be needed. |

Like I said, there are so many voices, each drowning each others predictions. Uncertainties abound and we will never know if indicators are controlled or falsified.

Sandali lang nasaan na ang sinasabi at pinagyayabang ng Pinakatahimik na Pangulo na si PNoy ang Iraq size oil natin? May nakakita na ba?

http://www.youtube.com/watch?v=ImV1voi41YY The IEA has now confirmed this: http://www.youtube.com/watch?v=YK730U0Q4NU In which case, it's already too late to make predictions about what has already taken place. Even with SA increasing production by 0.5 mb/d, they have yet to reach the 10 mb/d production rate they mentioned months ago: http://ftalphaville.ft.com/blog/2011...uction-puzzle/ And this is taking place amidst high oil prices (which should lead to a ramp-up of production to take advantage of such, but isn't happening). In fact, SA now admits that the price is right: http://arabnews.com/saudiarabia/article564187.ece to cover production costs, which have, not surprisingly, gone up because of high oil prices. Meanwhile, "Saudi Arabia to spend $100bn on 16 nuclear plants" http://arabnews.com/economy/article545341.ece |

Nobody can measure oil and gas reserves. The numbers are estimates based on interpretation ---often quite a lot of interpretation ---of sparse data about indirect indicators like well and seismic information. Tipee, B. Reserves numbers aren’t oil’s only market perplexity.

Forbes, by Tim Worstall, Contributor I wrote recently about how peak oil is a rather nonsensical concept: technology is advancing at such a rate that we’re discovering entire new planets to explore for the stuff. The latest comment to come back to me on that argues that because of ERoEI (Energy Return on Energy Invested) peak oil really is a serious problem and, essentially, that I’m all wet for disagreeing. The problem with this is that while the math and physics of ERoEI is just fine, indisputable even, it’s just not a very useful conceit except in certain very limited situations. Basically, what is being said is that as oil gets deeper, more difficult to pump up, perhaps with tar sands we’ve got to use more energy to purify the stuff, then at some point we hit a boundary, a system boundary. We’ll be using more energy to get the oil out than we’ll get energy from the oil we get out. Which, self-evidently, is nonsense, that’s like the internet companies losing money on every transaction and they’ll make it up in volume. That is, as far as I understand it, the argument. And it does work in certain special situations. It would indeed be self-evidently absurd to use 10 barrels of oil at one site to pump up one barrel of oil. Better, obviously, to use one of the 10 you have and have 9 left over. However, this doesn’t work as an assumption about the wider world in general. For energy comes in a number of different forms, dispersed, concentrated, at various different times, some of it is directly usuable, other of it has to be transformed to become so and so on. We have, for example, no problem at all in using tonnes of one form of oil, shipping diesel, to get an aircraft carrier and it’s aviation gasoline close to the Libyan shore so that a few gallons of that avgas can be used to bomb Ghadaffi (OK,so should be past tense there). We’re just fine with using fuel to get fuel to places. But let’s really go wild here and think about something very different indeed. Take, for example, the humble loaf of bread, the staff of life. We use vastly more energy to create that loaf of bread than we get out of having produced it. Leave aside the oil use, the fertiliser, the transport, all of that. Consider instead just water. It takes 1,000 tonnes of water to grow a tonne of wheat. That water must be fresh water. Producing fresh water requires huge amounts of energy. The Sun does this very nicely for us, evaporating it from the oceans and sending it back down as rain again. Now, think of the energy that is required to evaporate 1,000 tonnes of water…..that’s 1 million kilos at 419 kJ per kilo. 419 million kJ. There’s around 3,000 calories in a kg of wheat. So our tonne of wheat provides us with 3 million calories. 3 million kcal (nutritional calories that is) is 12560400 kJ. A little over 12 million kJ. So, in producing that staff of life, those grains which keep the entire world turning, we use 35 times as much energy as an input as we get as an output.

Peak Oil and ERoEI: Still Nonsense
52 comments, 10 called-out + Comment now PAGE 2 OF 2 And we’re quite happy with this. We don’t think it odd at all. And we most certainly don’t say that it’s unsustainable because it doesn’t pass the ERoEI calculation. The reason we’re not worried about it is because we’ve got vast amounts of energy coming to us as sunlight. Huge, massive, great big gobs of it. And we’re entirely happy to use it copiously, waste huge amounts of it, because there is so much. We want that energy in a form that can be used by our bodies and we’re just delighted to waste 97% of the energy in order to get a bit in the form we can use. ERoEI just isn’t a binding constraint on our system, not at any human scale. Sure, the entire world cannot use more energy than there is available to the entire world, that’s true. And it is pretty silly to use more of one form of energy to produce less of that same form of energy. But outside those two special cases, ERoEI just doesn’t mean very much. And the reason that ERoEI doesn’t mean very much is that we’re not, an any kind of human scale, limited by the availbility of energy. The Sun simply pumps in so much energy that total energy availability simply isn’t a binding constraint upon us. What we’re interested in is usable energy and we’re quite happy to waste total energy in order to get usable. As in the growing wheat example, there’s 35 times more energy going into the system than energy we get out of it and yet we’re all just entirely delighted with said system. So no, I’m sorry, ERoEI does not in fact mean that peak oil is inevitable or even a problem even if it is. For the math and the physics of the idea only apply in certain very specific circumstances, not as a general rule across life or the planet.

Ironically, the first half of his message not only acknowledges but even illustrates EROEI, i.e., the resources and energy to make bread. The only evidence (if it can be called that) that questions EROEI can be seen in the fifth-to-the-last paragraph of the article, where he refers to sunlight. But he does not connect the first half of his article with his second, i.e., considering what's needed to capture, store, and use energy from sunlight requires oil, from petrochemicals to various minerals that are extracted and processed using oil. He tries to defend himself further in his comments by arguing, for example, that there are millions of tons of rare-earth elements available, but he doesn't note the amount of energy and even various resources needed to extract, process, and distribute them. He makes the same mistake for copper and other necessities. To make matters worse, the same argument--that there are lots of resources available and that we should not be concerned with the energy needed to use them--ironically works against the need to resort to sunlight. Put simply, since there is lots of oil available and we shouldn't care about the cost of extracting it, then we should not have to be concerned with sunlight or rare-earth elements! |

Here's some info on the author:
http://seekingalpha.com/author/tim-worstall You mentioned earlier that you prefer peer-reviewed journal articles and reports. Might this help? http://www.mdpi.com/journal/sustaina..._Studies_EROI/ |

So, did you believe we need to spend energy 35 times over to produce what energy a single loaf of bread gives? Per ERoEI calculations?
Does it make sense spending that much? 35:1 ERoEI? Fast-forward to the Philippine setting: do we spend more energy today on growing rice than what energy we get from eating rice? If so, how much is the ERoEI? I am asking this so that we will plan our future using your ERoEI. If the computed ERoEI is over the standard ERoEI level set by your ERoEI scientists, what food do you suggest that needs to replace rice?

But no amount of money creation solves these problems. We can increase money supply many times more (we've actually done that, as we have between $600 trillion and $1.7 quadrillion in unregulated derivatives worldwide) but that will not change the amount of energy needed to extract and process more resources or even minimize pollution. About the EROEI for food, from what I remember, we need to expend the equivalent of around 8 calories to produce a calorie of food. We never noted that simply because for many decades oil was very cheap. That is, by consuming only around a barrel of oil we could get a hundred barrels from the ground. That is no longer the case. Finally, we (that is, PH society) cannot plan for this because, as stated earlier, we use money to measure the economy. In addition, the economy has to keep growing because more want a middle class lifestyle (e.g., passenger vehicles, houses or condo units or flats, appliances, etc.), which means we need to consume even more energy and resources. That is why resource consumption in Asia has been growing and is offsetting demand destruction in OECD countries brought about by increasing debt. Ultimately, a combination of resource shortages, increasing debt, and the effects of environmental damage (including climate change) will force people to localize and to let go of a middle class lifestyle. That will mean, among other things, growing food, including potatoes. Last edited by ralfy; February 15th, 2012 at 07:56 PM. |

So, for all the discussions we've done, it is really an accepted fact that this ERoEI is just useless because it simply is not used. Not playing with semantics there. (No pun intended)
BTW, it seems to me you skirted away from my question. You discussed the monetary system instead, though just the skin of it. FYI, our Central Bank cannot just print money just because it wants to. Please read what is written at the back of every bill on your wallet and you'll know how it is.

On your claim that derivatives are unregulated here in our country, am really sorry, I don't believe what you are saying there. I know there are banks trading derivatives but I know they are regulated by our CB. IDK where you get your data but here's what Mr. Tetangco once said in 2009 IIRC: "Philippine financial institutions have relatively limited exposure to structured credit and related derivative products which were the main cause of the large losses of crisis-affected international banks. It is helpful to point out that derivatives licenses in the Philippines have been given out prudently."I do know that oil prices has nothing to do with Oil Peak or supply issues but on these derivative markets that handles how oil are traded: The price of crude oil today is not made according to any traditional relation of supply to demand. It is controlled by an elaborate financial market system as well as by the four major Anglo-American oil companies. As much as 60% of today's crude oil price is pure speculation driven by large trader banks and hedge funds. It has nothing to do with the convenient myths of Peak Oil. It has to do with control of oil and its price. How?READ HERE

But that's the easy problem, as money can be created and be vaporized easily. Remember, much of it consists essentially of numbers in accounts. The hard part is the effect of increasing production and consumption, which is a resource crunch. On top of that are the effects of pollution, including climate change. No amount of funny money will solve these problems. Quote:
