Peak oil in the rear-view mirror?

That's what a new report from the German Energy Watch Group says - crude oil output peaked in 2006 and will fall 7% a year along with declines in gas, coal, and uranium.

According to this report in Guardian Unlimited, world oil production will be reduced by 50 percent over the next two decades leading to "wars and social breakdowns".

"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.

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."

It doesn't appear as though any government is really going to do anything about this until a full-blown crisis develops.

As each week goes by, the odds get better and better that Matt Simmons' 2006 prediction just might come true - that peak oil will be a more important election year issue than global warming.
