It's a small point not worth arguing, IMO (the difference between 'oil will run out' and 'oil will become too expensive to get').

The problem is that we are not exploring other forms of energy at a rate fast enough... (Brucie)

I disagree. It is not a minor point but one of the main points in this discussion. What you wish for in your second paragraph will come exactly when the price for oil goes up. The renewables will win when they can compete economically. That's a scenario I hope for.

Of course, it is necessary to calculate all costs: for all energy production models. That will include birds killed by wind energy, species lost to clearing for biodiesel production and so on.

In the physical sense, oil will never run out. When the price goes up the oil stocks go up as well, for then new stocks can be exploited at a marketable price. When the price goes up even more shale oil will become marketable (vast stocks of that, measured in centuries and not decades). Coal has been transformed into oil in Germany during WWII. If you add all coal stocks to the oil....

I'll look for a quote from the early 19th century moaning that coal will be depleted all too soon.
