GEOL 241 Fall 2017 Lecture 10: “Peak oil†(and gas, and coal) …or
Humanity will eventually shift away from fossil fuel energy. This is not a question of if, but when? The answer depends partly on two reasons: (1) Supply (because we run out) – a question we will consider today OR (2) Consequences (if we decide to stop using them) – a question we will discuss in the next 2 weeks, e.g., because of climate change.
A reminder about non-renewable resources: The feasibility of recovery depends on technology as well as economics – remember recent changes in unconventional fossil fuels. Despite high prices, advanced technology and a desire to be independent of foreign oil, production of oil in the U.S. peaked and declined, showing no signs of increasing even as of the late 2000s, which led to concern over imminent “peak oil.”
The Hubbert Peak & the concept of “Peak Oil”: Dr. King Hubbert, from Shell Oil, predicted that oil production should reach a “peak” and then decrease. His predictions for U.S. production were generally remarkably accurate until the last ten years. All oil fields follow a pattern of rapid development and production, followed by a rapid fall in production.
We know that: Oil wells peak, oil fields peak, regions peak, and the world will peak. Statistical behavior in oil production is remarkably predictable and follows a linear trend when plotting P/Q versus Q, where P = production in a given year and Q = total production up to that point in time.
For the U.S. Lower 48, the maximum cumulative production (Qt) is estimated at 198 gigabarrels of oil, which reflects the peak that occurred in the early 1970s. The Hubbert approach provides a statistical model for growth or decay based on historical trends, indicating possible future performance. However, are we currently near the global “oil peak”?
Many opinions exist regarding the future of oil production, with predictions of a dire future being common. Resurgent U.S. production in the 2010s raises questions about whether the “real” peak in total oil production has yet to come. U.S. production reached a “new” peak in 2015 due to fracking technology and increased investment in marginal resources, but it decreased in 2016 due to declining oil prices.
Historical statistics indicate we may be reaching a global peak in conventional oil production. The rise of “unconventional” sources of petroleum is changing views on peak oil, though these unconventional sources often come at a higher price and with market volatility. The debate centers on what “easy” oil really represents and whether it reflects a true end to peak oil or merely the evolution of energy production methods.
An essential aspect concerning oil is the fluctuating price and its effect on production. After years of incremental increases, prices for oil have dropped, prompting questions about the sustainability of U.S. production and whether new unconventional sources can compete, especially when oil prices are low.
Concisely summarizing the peaks, it is evident that while peak oil -- which indicates a maximum level of production that cannot be sustained -- suggests that we still have considerable resources left. The misconception that peak oil means we are running out of oil is misleading since a significant quantity of oil will remain underground. The economic feasibility of extraction can fluctuate based on energy source alternatives.
Looking beyond oil to gas and coal, there is a consensus that they too will likely show peak production curves. The historical data on these resources reflects similar trends, indicating that these sources of energy will not last indefinitely. Assessing total fossil fuel reserves versus production highlights that current demand and reserve levels suggest an impending challenge in sustaining future growth in energy consumption.
As oil consumption grows at a rate of roughly 1.6% per year, projections indicate we could exhaust conventional resources by around 2100, depending on continued global energy demand increases. If the average growth rate were to continue over the next century without shifts to alternative energy sources, we could face significant depletion of fossil fuels.
Overall, peak oil discussions are not limited to mere quantities of oil but revolve around broader implications, including environmental considerations, energy consumption sustainability, and economic development. As we move forward, might peak demand for oil arise as society transitions toward more sustainable energy practices and technologies?

The concept of "peak oil" refers to the point in time when global oil production reaches its maximum rate, after which production will gradually decline. This pivotal issue has garnered significant attention as humanity grapples with the finite nature of fossil fuel resources and the implications for energy sustainability. To understand the context of peak oil, it is essential to explore the historical patterns of oil production, technological advancements, and the evolving energy landscape.
Historically, as noted by Hubbert's model, oil production typically follows a predictable pattern wherein production rises steeply before reaching a peak and subsequently declining. This trend can be observed in the United States, where production peaked in the early 1970s. While the introduction of techniques such as fracking has rejuvenated U.S. oil production, concerns persist about long-term sustainability and economic viability as conventional oil sources are depleted (Hook, 2016).
Multiple factors influence the future trajectory of oil production. One fundamental aspect is the technological advancements that allow for the extraction of unconventional oil sources, which may extend the timeline for peak oil but often do so at an economic cost. As the efficiency of these methods improves, they could provide a buffer against imminent supply shortages. Nevertheless, the environmental impacts and market dynamics associated with unconventional oil production cannot be overlooked (Wright & Hearne, 2017).
Another critical consideration is the interplay between supply and demand. Demand for oil continues to rise, driven by global population growth and economic development, particularly in emerging markets where fossil fuels remain the primary energy source. This rising demand, when juxtaposed with finite supply, highlights the precarious balance facing policymakers and industry leaders (International Energy Agency, 2019).
Moreover, debates around climate change and the transition to renewable energy sources are intensifying. The detrimental effects of fossil fuel consumption on the environment prompt calls for a transition to sustainable alternatives. This shift necessitates a reconsideration of energy policies and practices to ensure that the global economy can adapt while minimizing environmental harm (Sovacool, 2018).
Extensive research indicates that while conventional oil production may peak, the availability of “unconventional” sources provides a significant yet limited buffer against complete depletion. Estimates indicate that substantial reserves of fossil fuels remain available; however, the economic feasibility of extraction remains a pivotal issue (Rutledge, 2014). As the extraction of tougher resources becomes increasingly prevalent, it is important to analyze the long-term sustainability of these methods.
In evaluating fossil fuel viability, it becomes crucial to assess not only the reserves but also the total resources available globally. Proved reserves are a function of current production rates and known deposits; thus, projections from 2014 indicated the potential longevity of resources, with estimates suggesting ~50 years at current consumption rates (Jaccard, 2006). Yet, if consumption continues to grow, projections suggest that even the most conservative estimates may be rendered obsolete by the end of this century.
Simultaneously, the evolving energy landscape is shaped by competition from renewable sources. As technology in solar, wind, and battery storage develops, these alternatives could present a viable future energy portfolio, further challenging the market dominance of fossil fuels (Lund, 2019). Hence, the question becomes not only when peak oil will occur but also when and how society will transition to alternative energy sources.
In conclusion, understanding peak oil extends beyond mere geological and production concerns; it encompasses economic, political, and environmental dimensions. Policymakers and industry stakeholders must anticipate the implications of peak oil and prepare for an energy ecosystem where the balance shifts from fossil fuels toward sustainable practices. The future of energy lies in understanding these complexities and proactively addressing the emerging challenges of a changing world.
