You mean, abiotic? Abiotic means unrelated to living organisms. For example, the abiotic theory of oil origin maintains that oil is not a product of decay of living organisms, but rather, a product of chemical reaction between iron oxide, marble, and water at pressures above 30 kbar and temperatures of about 1,500°C.

Abiotic factors are the non-living factors of the earth which affect the ability of living organisms to survive in an environment. These can include both physical and chemical factors.
The main factors affecting the growth of plants and where they grow can be associated with abiotic factors rather than biotic factors, which contribute less to their existence.
Physical abiotic factors include soil, weather, and the availability of consumable water. Natural disasters can also be considered abiotic.
Chemical factors include the amount of sunlight and the pH level of the soil.

The peak oil theory says that oil production will reach a peak, or already has, and then as production declines while demand increases, our oil-dependent global industrial system will break down. That link goes to a great essay on the issue by James Kunstler. Here's another good summary on Life After the Oil Crash. And for a ton of graphs and links, check out Die Off or the bloated oilempire page. It's all pretty non-controversial, unless somehow there's a lot more oil than we think.
