$this->bbcode_second_pass_quote('oil_rocks', 'J')ust to clarify one point, i certainly do not expect it to go down in the next 10 years, or even the next 100 years.
I did a quick calculation. If oil consumption continues to grow for 100 years, what will be the total consumed in that time? Well, with a modest 1% growth, the world consumption will be about 80 billion barrels per year, with 7.6 trillion barrels consumed between now and then. As we've consumed about 1 trillion, so far, that means, oil_rocks, that you expect the world to have something over 17 trillion barrels of recoverable usable oil (assuming that there won't be a decline cliff immediately after your 100 year period). If the growth turns out to be 2%, on average, that total consumed kicks up to 11.7 trillion barrels, with a total recoverable amount, since year 0, of over 25 trillion barrels. Even an average growth rate of 0.5% would result in an estimated total recovery of over 15 trillion barrels (assuming a decline curve that is similar to the increase curve).
These figures are way beyond even the most optimistic forecasts I've seen, of up to 7 trillion barrels, including tar sands and oil shales.
Why do you think you know more than those (even the most optimistic ones) who've studied this issue for years? Your opinion amounts to no more than a belief. It might be accurate, but there is no rational basis for it.
