LONDON, Oct 22: World oil production has already peaked and will fall by half by 2030, according to a report which also warns that extreme shortages of fossil fuels will lead to wars and social breakdown.

The German-based Energy Watch Group released its study in London on Monday saying that global oil production peaked in 2006 - much earlier than most experts had expected. The report, which predicts that production will now fall by 7 per cent a year, comes after oil prices set new records almost every day last week, on Friday hitting more than $90 a barrel.

The world soon will not be able to produce all the oil it needs as demand is rising while supply is falling. “This is a huge problem for the world economy,” said Hans-Josef Fell, EWG’s founder and the German MP behind the country’s successful support system for renewable energy.

The report’s author, Joerg Schindler, said its most alarming finding was the steep decline in oil production after its peak, which he says is now behind us.

The results are in contrast to projections from the International Energy Agency, which says there is little reason to worry about oil supplies at the moment.

However, the EWG study relies more on actual oil production data which, it says, are more reliable than estimates of reserves still in the ground. The group says official industry estimates put global reserves at about 1.255 gigabarrels - equivalent to 42 years’ supply at current consumption rates. But it thinks the figure is only about two thirds of that.

Global oil production is currently about 81m barrels a day - EWG expects that to fall to 39m by 2030. It also predicts significant falls in gas, coal and uranium production as those energy sources are used up.

According to the Guardian, Britain’s oil production peaked in 1999 and has already dropped by half to about 1.6 million barrels a day.

The report presents a bleak view of the future unless a radically different approach is adopted. It quotes the British energy economist David Fleming as saying: “Anticipated supply shortages could lead easily to disturbing scenes of mass unrest as witnessed in Burma this month. For government, industry and the wider public, just muddling through is not an option any more as this situation could spin out of control and turn into a complete meltdown of society.”

Mr Schindler comes to a similar conclusion. “The world is at the beginning of a structural change of its economic system. This change will be triggered by declining fossil fuel supplies and will influence almost all aspects of our daily life.” Jeremy Leggett, one of Britain’s leading environmentalists and the author of Half Gone, a book about “peak oil” - defined as the moment when maximum production is reached, said that both the UK government and the energy industry were in “institutionalised denial” and that action should have been taken sooner.

“When I was an adviser to government, I proposed that we set up a task force to look at how fast the UK could mobilise alternative energy technologies in extremis, come the peak,” he said. “Other industry advisers supported that. But the government prefers to sleep on without even doing a contingency study. For those of us who know that premature peak oil is a clear and present danger, it is impossible to understand such complacency.”

The German policy, which guarantees above-market payments to producers of renewable power, is being adopted in many countries — but not Britain, where renewables generate about 4 per cent of the country’s electricity and 2 per cent of its overall energy needs.
