nzheraldThe IEA's previous reports, which assured everyone that there was plenty of oil until 2030, were based on what Birol called "a global assumption about the world's oilfields": that the rate of decline in the output of existing oilfields was 3.7 per cent a year.
It turns out that production in the older fields is really falling at 6.7 per cent a year. Birol assumes, or rather pretends, that new production of "unconventional oil" (oil extracted from tar sands or oil shales) will allow total production to match demand for another decade until 2030, but this is sheer fantasy.
One writer in the Times in 1894 estimated that in 50 years the streets of London would be buried under 3m of manure. In fact, within 35 years the streets of London were almost completely free of horses, and filled with automobiles instead.
They created a different kind of pollution, but at least you didn't step in it. The same fate is likely to overtake oil-fuelled vehicles in the next 35 years. The shift will be driven by concerns about foreign exchange costs and energy independence, and increasingly by the need to curb greenhouse gas emissions.
It is starting with ever-tightening standards for fuel efficiency. That will be followed by the first mass-market generation of electric vehicles, due in the next two or three years. So American oil consumption is going to start falling quite fast, quite soon.
The same is true elsewhere. Indeed, it is a safe bet that the demand for oil is going to fall faster than the supply over the next 10 or 15 years, even if we are already at or near "peak oil", for the annual decline in oil production just after the peak is actually quite shallow - around 2 per cent - in the classic Hubbert curve.
