It is possible to predict with certainty how much oil will have been extracted worldwide when the "oil era" is over
What will be an ideal response?
We do not yet have the peak reached. At that point, when the production curve
turns over, we will be able to make that estimate. Peak oil production is expected within the
first decade of the twenty-first century.
