The struggle for global supremacy between Germany and Britain at the beginning of the 20th century drove them to search for alternative fuels to power their bulky coal based war machines.

The discovery of oil fields in the Middle East in the early 20th century spurred a century of new technologies, created new patterns of society and consumption and changed the global balance of power.

Fossil fuels by their nature are limited and will eventually diminish. For most of the 20th century this was never a discussion as most of the world’s oil was still undiscovered. With technologies such as the fighter jet, tanks and automobiles all designed to run on oil, if oil is drying up then apart from oil prices exploding, such technologies would also become redundant.

‘Peak oil’ was first introduced in the 1970’s; it is a theory which calculates the point where half of the worlds known oil reserves have been pumped.

There are three vital numbers that are needed to project future oil production. Firstly, the tally of how much oil has been extracted to date, a figure known as the cumulative production. The second is an estimate of reserves; the amount that companies can pump out of known fields before having to abandon them. Finally, one must make an educated guess at the quantity of conventional oil that remains to be discovered and exploited. Together they add up to the ultimate recovery i.e. the total number of barrels that will have been extracted when production ceases many decades from now.

The easiest way to comprehend an understanding of peaking dates is to see if production of oil has outstripped oil discoveries. The most damning evidence for this is that oil discoveries actually peaked in the 1960’s. The most recent large oil field was discovered in Mexico in 1985, while the majority of today’s producers have mature fields that were discovered in the 1950’s. The world now consumes four times the quantity of oil as is found. The oil companies are spending a fortune on trying to find new oil reserves, but the ones that they find are getting smaller and smaller, and therefore produce less oil. With diminishing discoveries the current production of oil is depleting the last reserves of the black gold.

Some overly optimistic predictions give peaking dates up to the year 2060, but the most reliable estimates for when global oil production will peak vary from between now and 2012. If production is meant to start diminishing worldwide very soon, then we should already see countries that have reached their peaks or are just about to reach their peak. Of the top seven oil producers, six are in decline or near peak production. USA peaked 1971, Norway peaked 2001, and the UK peaked in 1998. Russia, Mexico and China are forecast to peak in 2008. It is also possible that Saudi Arabia peaked in 2005. The only one of the top seven producers that has clear capability to increase production is Iran.

There are a number of other factors that support the early peak argument. Major oil companies (e.g. Shell) are finding it difficult to replace reserves and to backfill previous reserve over-estimates.

Oil industry consolidation hides reserve shortages by combining existing reserves. Oil companies such as BP have resorted to replacing reserves through production agreements on old fields (e.g. Russia) rather than pure exploration. Investment in exploration is falling. Technical feedback from the state of major Saudi Arabian oil fields indicates a high level of depletion. US foreign policy visà-vis the Middle East, Afghanistan, CIS, India, China and Asian states indicates frantic scouring for oil and gas.

It is these reasons that have allowed peak oil to enter the mainstream and the view that the world is running out of oil is considered a geopolitical headache for the world’s powers. However in reality this argument masks a number of deeper political issues.

The world is running out of oil is a convenient excuse for the West’s over consumption, since to reduce consumption is considered the ultimate taboo. As more and more nations scramble for the ever dwindling supply of oil, this has exposed the West. The Western world consumes 50% of the 21st century’s most important resource but produced less then a quarter of it. It is over consumption rather than the fact that oil is depleting that is causing the energy crisis.

The US specifically produced only 8% of the world’s oil but consumes 25% of it. Such huge consumption by the West is never sustainable; this is because the West essentially has relied on a relatively small number of mammoth fields for the lion’s share of their daily intake. Though the world possesses tens of thousands of operating fields, only 116 of them produce more than 100,000 barrels per day and they account for 50% of global output. Of these, all but a handful were discovered more than a quarter of a century ago, and most are showing signs of diminished capacity. Indeed, some of the world’s largest fields – including Ghawar in Saudi Arabia, Burgan in Kuwait, Cantarell in Mexico, and Samotlor in Russia – appear to be now in decline or about to become so. The decline of these giant fields matters greatly. Compensating for their lost output will take increased yield at thousands of smaller fields, and there is no evidence that this is even remotely possible.

As US consumption continues to rise, the competition for dwindling energy sources will intensify.

This will make the Muslim lands even more important and as with Iraq, occupation may well be justified for stable supplies of the black gold. Although oil is running out, it is due to Western consumption patterns rather then there merely being too little oil.
