Peak oil seems to be making something of a comeback to the mainstream media lately, with a recent report by the UK Energy Research Council prompting articles like this one from the BBC - Warning over global oil 'decline' .
There is a "significant risk" that global production of conventional oil could "peak" and decline by 2020, a report has warned. The UK Energy Research Council study says there is a consensus that the era of cheap oil is at an end.
But it warns that most governments, including the UK's, exhibit little concern about oil depletion. The report's authors also state that the 10 largest oil producing fields in the world are all in decline.
As this report points out, the debate about peak oil is a polarised one.
On one side, there are those who say that global supplies have already reached their zenith, and we are unprepared for the crisis that will hit world economies in the years to come. On the other, there are oil companies and many energy analysts who dismiss the notion that supplies are running out.
The report's authors admit it is hard to tell who is right, as the world lacks a reliable gauge with which to measure oil depletion.
