Peak Oil (or Theory) postulates the point at which the world's oil supplies go into irreversible decline. Based upon M. King Hubbert's 1956 statistical modeling, United States oil production would peak between 1965 and 1971. [1] He projected a roughly symmetrical curve of production, being initially correct with his call of a peak. However, his predictions proved premature since US production has been increasing again steadily since 2010, breaking out of the Hubbert Curve. [2] In the popular imagination the Peak Oil doomsday scenario entailed soaring costs and a strict rationing of, and battle for, leftover reserves. [3]

Supply of Oil

The Peak Oil thesis hinges on the supply, or lack, of oil. A peaking in oil production necessitates a decrease in oil sources and thus supply. As currently demonstrated in EIA data, the current U.S. Crude Oil production, as of 2013, is at an average of 7.462 million barrels per day. [4] Correlated to this is the discovery of new oil fields usable for production. Discover has, however, been steadily declining since then to around 10 billion barrels per year between 2002 and 2007. [5] Yet this has increased somewhat to a steady rate of 15-20 billion barrels per year since 2010 mainly due to the extensions of additional oil found in existing fields. [6,7] There is, however, discussion over the actual state of world reserves, with concerns being raised about the validity of official reports. For example, in 2004 there was an "evaporation" of 20% of Shell's reserves. [8] The corporation admitted to overestimating its reserves by 20%, showing how difficult it is for producers to give accurate and tenable accounts of global oil reserves. [9]

Timing of Peak Oil

General consensus estimates predicts world oil production to climax between 2010 and 2030, with anything after 2030 deemed impossible. [10,11] The general uncertainty concerning the actual state of global reserves, however, makes a more specific estimate impossible. The majority of papers published after 2010 have been relatively pessimistic. A 2010 Oxford University study predicts production to peak before 2015. [12] In general, world crude oil production and the quantity and size of proven reserves have been at a record high since 2012. [13]

Possible Consequences

As to report by the United States Department of Energy published in 2005, a peaking of world oil production will entail a drastic increase in liquid fuel prices and price volatility, with unprecedented economic, political, and social costs. [14,15] The main problem a peaking of oil production poses is that of price volatility. The Stanford Energy Modeling Forum found that the economy can adjust much better to steady, gradual increases in price than bigger, sudden swings. [16]

Criticisms

There is, however, criticism of Peak Oil Theory claiming it is unsubstantiated, leading to multiple efforts being undertaken to stem against a peaking of oil and even support the diversification from it. An example of this is algae fuel. One can produce biofuel out of algae via heterotrophic fermentation, allowing for highly controlled conditions. This can possibly generate a very high yield of biomass, better than comparable resources. Importantly, algae-produced fuel seems to not demand extensive distribution modifications. [17]

Conclusion

Peak Oil Theory is pressing to become an important issue in the light of the search of new oil reserves necessary to counterbalance the increase in demand. However, there is also significant evidence to undermine Peak Oil Theory, with critics citing the diversification from oil as well as the scientific progress made to explore new means of producing it.
