CoHo:

Forgive me if this point has already been made, but no finite resource can be exploited infinitely. "Conservation," or avoiding waste, can delay the inevitable, but once finite resources like petroleum and coal become more and more expensive to extract, their products and benefits will increasingly become the property of, and for the exclusive use of, the most wealthy. As such points are approached, "production" will fall, hence consumption will fall too.

The burning of petroleum removes this highly efficient source for higher-priority uses like lubrication and, say, sterile, disposable/recyclable products like hypodermic needles (which have saved many a life and extended life-expectancy) from the equation earlier, meaning that extraction of energy from biological sources will become even more uneconomical than it is now (even now it is largely a heavily subsidized con-job). "Biofuels" are only possible because of fossil energy inputs, now, and the basic con is that outputs exceed inputs. However, that is doubtful, and even the "calculations" made to justify this practice (which diverts agricultural space and products from food production, thus raising food prices, and increasingly lays waste to complex ecosystems) can claim only marginal net outputs in excess of inputs (like sugar-cane). The "catch" is that sugarcane can't be grown just anywhere (and the expansion of sugarcane production or any other crop-based source of energy requires the destruction of the ecosystems that now occupy the space "converted" to such production. The value of such ecosystems is NEVER factored into such calculations.

All world cultures are on a terminal binge--terminal, not just for humans, but for much of the earth's life.

There is no free lunch.

http://en.wikipedia.org/wiki/File:TPES_outlook.jpg

The Dept. of Energy has compiled a graphical representation of energy
sources now in the future.

If you can display the above webpage on your computer, you will see that the
sources of energy are listed in order of decreasing importance as follows:
1. Liquid (Oil mainly)
2. Coal
3. Natural Gas
4. Renewables (Wind, Water, Solar)
5. Nuclear

Anyone who believes that non-fossil sources of energy are the wave of the
future should take a look at this chart.
