The Swiss are an environmentally aware and active nation and generate around 20% of their electricity from hydropower. Other than this they are as dependent on fossil fuels as the rest of us, and as far as I know they have little in the way of natural resources such as gas, oil or coal. I have had a long love-affair with Switzerland, beginning with a holiday there 24 years ago, walking in the Bernese Oberland, and visiting the Reichenbachfalle (Reichenbach Falls) where fictionally Arthur Conan Doyle killed-off Sherlock Holmes' arch-rival, Professor Moriarty, in a death-struggle the two of them had, which resulted in both falling. Holmes was later found to have survived, such was public demand that Conan Doyle wrote more of his fabulous stories on the detective of his imagination, even though the author himself had had enough of him.
The basic idea is that there weren't enough dinosaurs to have been cooked into the vast amount of oil that has been recovered to date, let alone the other half of it that is thought recoverable. There is much debate about how much oil there is to be recovered and Richard Pike (CEO of the Royal Society of Chemistry) was quoted recently as saying that there may be twice as much oil left as was thought - perhaps twice the figure of around 1200 billion barrels. Now that all depends on what precisely is meant by oil, and if you count-in heavy oil, bitumen from tar-sands and oil-shale, maybe there could be 2.4 trillion barrels of it. 3.7 trillion barrels is one estimate I have seen but that counted-in everything including coal-to-liquids conversion.
The real limit is the rate of recovery, however, not how much "oil" there is down there or could be synthesised. Also, while it is nice to see that the price of a barrel of oil is down to around $120 from almost $150, my money is still on a steady increase in the future as none of these oil-sources are likely to be cheap. One wonders too whether the world powers have conspired to pull-down the price of oil in order to preserve the global economy, which could collapse if it rises high enough. Apparently, in the U.S., there has been a fall in the amount of fuel used during the past few months, which is unexpected since people normally drive more during the summer, but not at $4 a gallon, perhaps. Still, it's nearer $8 a gallon over here, the most expensive fuel in Europe.

Universities Beyond Peak Oil.
As is true (...so it is claimed) of the school system which now awards numerous "A" grades at A-level, this miracle is accomplished by teaching to the exam-paper. In my days as a university professor in physical chemistry, had I not followed a similar practice most of the students (customers) would have failed and it would have all been my fault for my rotten teaching. That said, I still give some lectures when invited and I get invited back, so I can't be all that bad in expressing the fundamentals. In other words, you don't exactly tell them what the exam questions are but you make pretty darned certain that they have similar calculations in their lecture notes to refer to.
Otherwise it would inter supra be chaos, as attested to the fact that on one occasion I set coursework for 14 students, gave them the formulas and received 14 different answers even though all they had to do was put the numbers in. "How do you know that?", I was often asked. "I just worked it out." I said. "What, in your head." "Yeah." Now this is just school-level stuff mostly, but I was taught to read and write and do sums and I thank the British education system for this. Everything else was down to my own efforts - broken home, general instability and leaving school at age 16... but at least I could read, write and do sums... the "3 r's", if you include aRithmetic.
The British university system, in its vast expansion of student numbers, also has many readers and professors. For those not familiar with how this is supposed to work, the mechanism is something like this: a lecturer dispenses the knowledge of their specialist subject; a reader is supposed to know the wider subject through their own research activities and publish them in a decent medium, and a professor to indeed profess, and dispense new knowledge. Not any more. This is indeed both a travesty and a disgrace.
Not in some of the newer universities, where a professor may have no published work even in the subject they are supposed to be professor of, although the title is given e.g. "Professor of Chemical Education", but in this age of irony, the suffix "Education" is the typical cop-out of any standards. There are also readers who do no and have never done any research, but then in other English-speaking countries there are people with a third-class degree running universities and telling the professors what to do - such is this enlightened age too of "management".
So, when mum and dad can't keep the kids at "uni" any more, what will become of the uni's? Surely it is time that the higher education system was adjusted to meet the needs of a nation, rather than allowing the market forces to decide how many bums on seats each has and hence their allocation of funding. This is the fault, as is the re-labelling of institutions as universities which are of no such item. In the age to come - the Oil Dearth Era (beyond Peak Oil) - we will really need people to know "stuff". The ex-polys will, if sense prevails, be restored to their good and proper role that they did so well as technical colleges which teach a young citizen to become a good plumber, electrician, engineer, cook or farmer - all the things that will be an essential part of the "world made by hand" as James Howard Kunstler entitled his novel, about human survival without oil, rather than churning out 50% of "graduates" who struggle to read and write correctly and certainly can't do sums. How many pharmacists or media studies graduates does Britain really need?
It is poignant too that all our "graduates" end up with a debt of around £15,000 now, in an accumulation of student-loans and top-up fees for this "privilege" - an indelicate situation, given the current condition of the economy.
However, the university system keeps everyone quiet in the illusion of progress while the reality of no more cheap oil - or food or fuel, in consequence - is a dirty fantasy.

Oil Net Trawls Arctic.
The Arctic comprises some of the world's most beautiful and pristine wilderness, a vista whose wildlife and purity is under threat from exploitation of the vast amounts of oil and natural gas which are believed to be interned there. Hailed as potentially "the new Houston", with 400 oil and gas-fields presently operating above the Arctic Circle, the scenario of a northern oil-scramble may represent the final phase of colonization. Noting from history, whoever owns the world's resources, especially those of energy, will dictate to the world.
The prospect of developing hydrocarbon extraction in sensitive and unique regions of the natural ecology has, unsurprisingly, upset many environmentalists. Arguably humans are part of the mechanisms of nature, and hence our actions are those of evolution. If we have contributed a perturbation of the earth-systems, though global-warming and climate-change, those regions are no longer pristine, but my gut-feeling is that it is wrong to compound it so visibly, in addition to more subtle means through changing the molecular composition of the atmosphere so that it traps more heat.
No one likes to see polar-bears clinging to chunks of melting-ice before they drown, unable to maintain their struggle for dry land, any more than they do sea-birds floundering in oil or great slicks of it soaking into sandy beaches. I am torn in my emotions to all of this, however. Worse still is the prospect of running-out of energy and the collapse of civilization, and marginally I might trade environmental dignity in the interests of human survival, in the longer run.
But, it is not merely a matter of survival, but of trying to satisfy a relentlessly raging thirst for energy, for power, for more, which in the nature of all addictions is unslakable. Economics will probably prevail in trying to maintain the status-quo, and so we tear-up the Arctic to unrest its oil and gas, but all this does is to buy us some potential transition-time, at best. Otherwise we merely postpone dealing with the problem, in denial, until the spiritual, mental and physical aspects of the three-fold disease of addiction are beyond treatment, and the corpus of humanity shuffles to its defaulted end.

Clean Coal Conundrum.
A coal-fired power station produces around twice the amount of CO2 that a gas-fired station does of equivalent generating capacity, and if carbon capture and storage (CCS) technology is fitted as well, the process requires another 10 - 40% worth of fuel to be burned. Put another way, it might take building a third station for every two to power the CCS for them all. The EAC heard evidence that there may be five or six new coal-fired stations built in the U.K. by 2015, although this does appear dubious since it takes around 10 years to build one.
The EAC has told the government that it must set a clear date by which companies must implement CCS or close their coal-plants down. It stresses that clean coal is a "fig leaf" whereby the government is able to claim green credentials in developing a low-carbon future (in line with EU greenhouse-gas targets) despite the fact there is no guarantee that CCS will will installed, which is an untried technology as yet, on the significant scale, and is also going to be expensive. Now that much is guaranteed.
"Unless there is a dramatic technological development, coal should be seen as the last resort, even with the promise of CCS", so concludes the EAC report. Tim Jones, climate policy officer with the World Development Movement, commented: "The government should not be relying on CCS - an unproven technology - to justify new coal power stations."
There is an issue too, of where this coal might come from since Britain only produces around a third of the coal it uses and hence a dependency on imported fuel remains.

Biofuel's False Promises.
It is difficult however, to contemplate such an action at a time of sharply rising food costs across the world, along with that of oil: the lifeblood of the global village. Most likely, the near emphasis will be on nations becoming as self-sufficient in food as possible, which would mean the U.K. producing another 50% of its own food in an inevitable compromise between growing crops for food or crops for fuel.
Thus, presumably, there is a sizeable proportion of non-arable land that is intended for use in the biofuels game, including forests. The latter is the focus of a study by Dr Renton Righelato of the conservation charity, the Woodland Trust, who emphasises that forest-land should not be cleared in order to grow fuel crops. The justification for "green fuel" is that as the crops grow they absorb CO2 from the atmosphere, and so the process of growth-harvesting-fuel production-fuel combustion is optimistically called "carbon neutral" implying a simple recycling of carbon-atoms in the chain.
Exactly how "neutral" biofuels are overall is a matter of considerable controversy, especially in the case of ethanol derived from corn. If it becomes necessary to clear forests, there will be a contribution to atmospheric CO2 since trees are highly effective absorbers of CO2 and also help maintain the integrity of the soil they grow in, which otherwise partially degrades, actually emitting CO2. Britain is "committed" to producing 10% of its fuel in the form of biofuel by 2020, apparently, it it manges to comply with E.U. plans on the subject.
According to Dr Righelato: "It is a mistake in climate change terms to use biofuels." The study is the first to reckon the complete CO2 emissions tally of planting, extraction and conversion into fuel. Reporting in the prestigious journal Science, his team concludes that the emission of somewhere between two and nine times more CO2 would be avoided by sequestering carbon in trees and forest soil than by replacing fossil fuels with biofuels.
It is estimated that 40% of Europe's agricultural land would be needed to produce sufficient crops to meet the 10% biofuel target, which is simply not feasible; nor is it in the United States, and hence it is likely that the demand will be borne for the West by developing nations. According to the National Farmers Union, 20% of Britain's agricultural land could be used to grow fuel-crops by 2010, but the Science report concludes that reforesting land would be a more effective means to cut CO2 emissions. The message is not one of "burn more oil" however, while planting more forests, but of curbing fossil fuel use and "moving to carbon-free alternatives such as renewable energy".
The latter we have heard many times before, as a kind of throwing-up of hands, but how exactly are we to substitute - quickly at that - oil-based transport (given rising oil prices and an imminent supply-demand gap for oil), if biofuels are not the answer, by "renewable energy"? It is the mobility of transportation that confounds here, compared say to basic electricity generation - hydrogen, electric cars what, how quickly and by what means?

Britain Rebuked for "Excessive Borrowing".
The European Union are to begin disciplinary proceedings against the United Kingdom for the latter's breach of its borrowing regulations . Under the European Stability and Growth Pact, the amount of money any country can borrow is 3% of its national earnings, as defined in the Maastricht Treaty. This action is tantamount to a formal warning that Britain should curb its borrowing or cut spending. Now the latter is a real bugbear. It is well-known that the United Kingdom has the most generous benefits system in the world. This year the government has needed to borrow in excess of £50 billion ($100 billion) to prop up this leviathan, along with all other "expenses", such as the NHS, and the various wars its armies are involved in.
The present system is simply unsupportable, but which government would admit that? There are apparently over 3 million Britons without work in Britain, and we need 1.3 million migrant workers to "do the jobs they won't do" as it is often phrased. The solution seems simple doesn't it? However, it is not. In order to cut public spending, a complete revamping of British society is necessary, and with costs for the status quo rising against a backdrop of inflating prices for fuel and food, something will give. By default if not by decision, the system will give-way, and the E.U. is simply telling us that this is the case.
We "lost" most of our manufacturing and coal-production and are dependent increasingly on imports of food and fuel, even coal. The North Sea oil and gas fields are yielding far less now (one million barrels a day compared with three times that 25 years ago) and so we are attempting to cement gas-supplies from other regions, especially Qatar in the form of liquefied natural gas. Projections of the gap between home production and imports of gas and oil are such that by 2013 the bill will be £500 billion ($1 trillion) in the red . To emphasise, that is only 4 - 5 years time, and undoubtedly, Britain's budget will fail long before then, unless we cut-back on our fuel use dramatically.
An acquaintance of mine told me recently that he "couldn't afford to work", because the benefits he receives from the state are far more generous than a low-paid wage. So, I keep him therefore by working and paying my taxes; not that I am rich exactly. The system seems set-up to fail under its own bulk and even paying my "friend" a government subsidy to encourage him to work would cost the welfare system far less than its present manifestation does, and a man would have the pride of doing a useful job rather than empty days and potential "work" being made for idle hands. He has a drinking and drug problem, which I think is partly caused by his years of unemployment (i.e. boredom). He's a decent guy and I feel that the Welfare State has let him down, and many others, by condemnation to membership of an underclass, who would have been respectable working class at one time - as my own family were.
Meanwhile there is a £7.5 billion "hole" in the U.K. national budget for next year  in consequence of that euphemistically termed "economic turn-down", which covers a multitude of sins. To place this sum in perspective, we may note that filling its hole through cuts would amount to sacking 57,000 teachers, cancelling the two new giant aircraft carriers ordered by the Ministry of Defence and closing five hospitals. Another 2p on income tax would also do it, but at a time when irate motorists and haulage companies are calling for the government to cut its taxes on fuel, this does not appear likely.
The poor British worker is being hit hard enough already to pay for everybody else, in the unsustainable system that has been allowed to evolve from the wholesome roots of 1947 to create that "land fit for heroes".

Russia set to Dominate World Uranium Supply.
The terms "energy" and "electricity" are often but incorrectly used synonymously. Only a proportion of total energy is used in the form of electricity, in the U.K. about one fifth; roughly 40% of the rest comes from oil used almost entirely to fuel transportation, and the remainder is thermal energy to heat buildings and run industry, more of which could in principle be provided via electricity if generating capacity can be expanded. The U.K. seems set to maintain gas-fired electricity output, even though there are issues over just how much gas we will be able to import in competition with other nations in Europe, and switching-over to more nuclear power from gas-technology will not be easy.
Last year, Russia overtook Niger to become the fourth largest producer of uranium, following Canada, Australia and Kazakhstan, with an output of 3,527 tons. There are however plans to recover much more uranium from deposits in Eastern Siberia and other regions and through deals with other uranium producing countries: Canada and Kazakhstan already have cooperative arrangements in place and there are explorations ongoing in Mongolia which it is thought may have the greatest uranium resources of any nation.
In the far-eastern Russian Chita Region lies the city of Krasnokamensk, home to the Priargun "mining and dressing" plant, which produces a massive 93% of Russia's uranium. The proven reserve there is 150,000 tons and another 7% is produced by underground leaching (a much cheaper process than conventional mining) in Dalur (Kurgan Region) and the Republic of Buryatia (Khiagda). In total these deposits are sufficient to meet home-demand only and so, if Russia is to become a major exporter and controller of the world uranium market, it has to yield more from elsewhere.
Additionally, Russia must provide uranium for soviet-built nuclear plants (e..g Metsamor in the Republic of Armenia and Kozloduy in Bulgaria) abroad, along with meeting contracts for uranium-enrichment and the overall result is a deficit of around 6000 tons a year of uranium. This shortfall from "new" resources is made-up by reprocessing uranium from nuclear weapons and "depleted uranium tails" which are deposits of ore that are used twice. However, these "secondary reserves" will be used-up in 10 - 15 years and so more actual "new" production is unequivocal.
In this regard, the Rosatom uranium monopoly, Atomredmetzoloto, intends to up its production to 3,880 tons (up 10% on 2007) and to increase this to 20,000 tons by 2024. As noted in the context of oil, it is the rate of supply (the "tap") that matters more than the size of the reserve (the "tank"). Russia has a very large tank of uranium, holding around 564,000 tons if the deposits at Elkon of 344,000 tons is included. Elkon is located on the banks of the River Aldan in Yakutia in the north of the Republic of Sakha, and the uranium ore is buried deep underground in a bank of permafrost and so digging it out will not be all that easy.
I wonder too, whether there will be disturbances of methane hydrate, releasing methane into the atmosphere in the process. The Argentines are measuring the gas-output from the arses of cattle at the moment which they fear might be causing 30% of Argentina's methane global-warming gas emissions, but what in comparison could mining Siberian permafrost turn-up?
All in all, experts have reckoned that Russia could produce 45% of the world's uranium by 2030, which, if nuclear power becomes as important as some think in the fight to wean the world off fossil-fuel, will place them centre-stage in world affairs.

This definition accords with James Howard Kunstler's usage, who writes a blog called "Clusterfuck nation", which describes a nation whose threads of ideology and infrastructure are codependently connected via the use of huge amounts of energy, car-dependence and hence oil. Thus in its addiction to the latter, it is ensured that the entire edifice must fail. Kunster is not a cheerful commentator, as in his book "The Long Emergency" and deftly played-out in his novel "World Made by Hand", where he invents a world which, if not downright apocalyptic, is entirely post-industrial, following a collapse of society and technology, and driven mainly by the toil of humans and other animals, and human ingenuity using hand-held devices, hence the title.
The aspect of codependency is common in the West. Kunstler is writing specifically about the United States, since he is an American, but in general, the problems and instabilities he alludes to are those of all of us, and I note with unsettling and compounding disquiet, that the news breaking on the British shores is not great just now and does little to promise better times to come. We are addicted to our lifestyles, which are comparatively comfortable and all forces conspire to enable a common addictive behaviour. No legitimate citizen should starve in the U.K. The welfare system is intended to take care of that, but with 49% of the British population on benefits of some kind (including pensions) and an economy that is starving of revenue, I wonder for how much longer that can be sustained.
When it was set-up in 1947, the welfare state was intended as a safety-net, not the way of life it has become for many. It has been argued that the system has contributed to social disintegration since broken families are "encouraged" by it, coupled with high ("real") unemployment, and this is a significant part of the rise in crime among sectors of the young : a lack of a sense of belonging and purpose. The welfare system props-up the mess without fostering the means to get out of it. Personal debts and government debts are high. If the economy is on the verge of a recession, the service sector will begin to contract and since we have "lost" most of our manufacturing industry, it is service-jobs that keep the money in circulation. Less money in people's pockets will hit retail and entertainment industries hard, resulting in job-losses, more for the welfare system to pay out and less in the way of tax coming back into it. The escalation in the cost of basics like fuel and food will compound these difficulties. A real clusterfuck situation.
I do not envy the present government its many tasks. Some solutions might be simple but harshly unpopular. Real vote-losers; but the present issues are of far greater magnitude than mere party-politics. How to unify a nation in economic decline and which will call its debts in? Mr Brown has called for the British people to waste less food. Good common sense, one might say. When I was a kid, food wasn't wasted. We didn't starve but neither did families put half-dozen different ready-meals into a microwave because one child wanted this, another that and another sibling something else. You ate it or went without. Perhaps there are too many choices now and this has contributed to the confusion and freneticness that we seek to escape from by buying more material things.
Ironically, it is cheaper to cook from basic ingredients than any number of BOGOF's (buy-one-get-one-free deals), which are under threat, being blamed for much of the 4.1 million tonnes of food that is wasted in Britain annually - around £1 billion worth or £400 a year for an "average" family, whatever that is these days. I reckon about 3 people per household given these figures. There is a lack of awareness of basic skills such as growing food, cooking it, elementary nutrition, household repairs and so on that were not that long ago, common knowledge.
I'm not knocking anyone or anything, and I am certainly not as pessimistic as Kunstler (probably because I can't bear to think that way), but in an age of unparalleled university expansion in Britain, there is an absence of fundamental teaching about how to live and to live within one's means. When the credit cards are taken away, the housing market has fallen and the welfare bill is no longer affordable, what otherwise will happen to this population, on the whole of pretty decent people, left without the wisdom and practicality of generations? Mr Brown, apart from not wasting food, what should be our priorities in the world at hand?

UK "Secondary Priority" for Norwegian Gas Supplies.
The UK has gone to considerable efforts and expense to build gas-infrastructure, both in terms of pipelines and gas-terminals, but this does not of course guarantee the gas will follow. We import 20% of our gas from Norway now and this fraction of our gas supplies was expected to increase ("Hands Across the North Sea: British-Norwegian Gas Connections", posted July 6th, 2007); however this is now in doubt. By 2020, Britain will need to import 80% of its gas; a significant amount (perhaps 30%) is expected from Qatar in the form of Liquefied Natural Gas (LNG), for which two storage terminals, Dragon and South Hook, are being completed at Milford Haven, in south west Wales. There is another LNG terminal at Isle of Grain, at Medway, Kent, but this hasn't received a cargo since January.
Illustrating the buyer-seller aspect of gas-supplies now and in the future, one anticipated shipment of LNG from Algeria was abruptly diverted to Turkey, because the buyer offered more money in consequence to an interruption of existing pipeline-supplies of gas by Iran. Gas-prices are set internationally and have been raised by rising bids from Japan, Korea and China, who are worried over securing gas-supplies. An earthquake in Japan knocked-out some of its nuclear-electricity production, thus forcing the nation to lean harder on gas-fired power.
There seems little doubt that unless energy-utilities in the UK are prepared to stump-up for competitive gas-prices, we may run-short, as precious resources are simply sold-on elsewhere in the global marketplace. Britain must meet the shortfall in urgently declining production from the North Sea, and we will have to pay through the nose for it. Even though British customers are encouraged to change their energy supplier, the overall costs of both gas per se, and electricity, much of which in the UK is made from gas, rise relentlessly.
Prices of oil, and of its siamese-sister gas, will continue to rise according to increasing demand against the limited and competitive availability of resources. Oil production is expected to peak soon and gas within a decade or so, which begins to set limits on the production side of the energy gap that threatens. Among its other deliberations, I hope the G8 will now begin to make using less in the way of fossil fuels, a priority. The world will not run-out of them for a very long time, but we seem to have run-out of the cheap stuff. Some estimates are that fuel prices will be higher by as much as 40% this winter, and that is whether demand can be met or not. We may have power-cuts and still pay for the privilege.

U.K.Fuel Tax Freezes, but Rising Prices.
Yesterday saw a truckers' protest in London, but I doubt it will have any effect in reducing fuel prices. Into this tinderbox was threatened the spark of the government increasing fuel taxes by 2p a litre, amid urgent calls to reduce it. The Daily Express newspaper has been bearing a flag that fuel costs could be reduced by 14p a litre, but since this would involve depleting the chancellor's coffers at an especially demanding time - Mr Darling has already had to borrow over £50 billion this year - I doubt tax-reductions are feasible. It seems likely that the 2p tax increase will be stalled, which would amount to, pro rata, around £1 billion a year.
Even freezing this fuel duty will provide little balm for drivers, however, who are paying around 120p per litre of unleaded and 130p per litre of diesel, the latter being a tough outlay for haulage firms who use mainly diesel as a fuel. The price of oil has increased by a factor of ten over the last decade, has quadrupled since 2004 and doubled in the past year. There is now speculation that it will reach $250 next year, and that will increase fuel prices by around 60p a litre, irrespective of what the government does regarding taxation: the £2 litre is in sight, or $15 a gallon (U.S.).
We will face very difficult times, undoubtedly, and the only glimmer of hope is that new technologies will become "affordable". Put another way, the cost of oil will be so outlandish that other means to preserve as much transport as possible might appear less expensive: e.g. electric, second generation biofuels, hybrid (I am leaving-out hydrogen/Fuel Cells for the moment since this technology is years away and poses a chain of technological challenges to be surmounted before it can really get anywhere) and probably most viable, fuel-efficient engines.
Meanwhile, the airlines easyJet and BMI have told their pilots to fly slower since this uses less fuel. I believe there is a technique that can be used at altitude, which is to lower the wing-flaps so that more lift is obtained, and hence less fuel is required to keep the plane airborne at a reduced velocity. Simultaneously, train-drivers have been recommended to switch off their motors and coast downhill at suitable points, and bus-drivers to "travel smoothly" to reduce the amount of fuel required per journey. The price of a litre of diesel is forecast to reach £1.50 this summer.
Energy efficiency has to be the way forward, but wrapped neatly in a whole reformed manner of living which is simply less transport intensive overall.

Gordon Brown and the Peak Oil Myth?
There are basic geological problems associated with oil production which cannot be sensibly surmounted. The prime one is that oil is buried at depth and under pressure and so when a well is first struck, the pressure of gas in the reservoir forces the oil out, but as the oil is extracted, the gas expands into the remaining volume so reducing its pressure and the oil is expelled more slowly. To maintain a decent flow-rate, the well may be artificially pressurised, e.g. with CO2, or sea-water pumped into it to displace the oil. Ultimately, the well is no longer viable to extract oil from and the company moves-on to another one. In addition, when oil companies explore for oil, they usually hit the largest fields first and exploit them, and hence as a particular region ages, it becomes necessary to start squeezing increasingly smaller oil deposits. Thus, the combination of these two "geological" factors means that decline of a field is inevitable as happened in the North Sea, irrespective of economic or political features.
So it is with all oil-fields, and tax-incentives will barely influence North Sea output or indeed that of the rest of the world. In the wider context, Mr Brown called the fact the OPEC controls 40% of the world's oil as a "scandal", when in fact the location of the oil is a bestowal from geology, and we can hardly blame the Arabs, Venezuelans or Indonesians for the oil under their lands. It was not they who put it there but some higher power. OPEC produces about 36 million bpd and the non-OPEC countries the remaining 50 million bpd or so. Things can change however, and according to the pressure/production argument above, they must. Accordingly, many experts now predict that OPEC output will peak at around 2010, and in effect that of the world.
The OPEC cartel probably has precious means for raising capacity overall. It may be able to push a little more out of existing wells, but this has to be measured against the fact that output from others is falling. Probably there is practically no overall excess capacity and most of the oil that will be produced (noting that oil will be produced for decades yet) will tend toward being of the heavier, high-sulphur varieties, for which additional refining capacity must be installed. Refining high-sulphur oil is expensive and so the product will not be cheap. The economic factor comes in through the increasing costs of exploration and extractive technology, in addition to the simple fact that an inability to produce more oil against rising demand will tend to keep the price up anyway.
But why worry? Apparently there is plenty of "new" oil to be had  which should cheer any politician who would rather not confront the only real solution to the oil-crisis and that is to use less of it. This is attacking the demand-supply gap from the other side. If we can't sensibly produce much more oil, then using less would achieve the same healthy supply-surplus. Easier said than done, I concede, but what about all this extra new oil?
Well, in a nutshell , it is claimed there are vast reserves of oil, as yet untapped. There are apparently 33 billion barrels off Brazil, and another 15 billion barrels of oil and gas in the Gulf of Mexico. There are other deep-water deposits,off West Africa and near Sleipner in the North Sea. There are also vast resrerves in Iraq and Iran. Then there is oil shale under much of the mid-U.S. and the Alberta tar-sands and Venezuelan ultra-heavy oil. Bakken shake too deserves a mention, under North Dakota, from which 4 billion barrels is thought a potential yield, to be compared with a total of 10 billion barrels in the Arctic National Wildlife refuge.
We could go on, and if coal-liquefaction is included there are estimates that we have 3.7 trillion barrels worth of hydrocarbons left. But sorry to spoil the party - so what? The mere amount of these hydrocarbons tell us nothing about the rate at which they can be extracted, and how much really can, by when or if at all. To access the deep water oil will require technology that is still under development, and all of the other sources will not be cheap and will require a great deal of engineering to exploit. We are on the verge of a gap that conventional production of oil is unable to bridge, and this is now lapping on the shores of peak oil, beyond which production will actually fall - for specified geological reasons.
Demand rises mostly from developing economies, e.g. China and India, and is maintained in any case by others, e.g the West. The "new" reserves will take years to develop and their oil will not offset the inevitable and imminent fall in traditional production. Welcome to the age of very expensive and increasingly scarce oil. Now, how are we going to manage with less of it, but in a positive way?
