Campfire post relating to a system where individuals gain status not by what they have, but by what they give away.
There is plenty of oil but . . .
There is a huge amount of oil that theoretically can be extracted, but the question is whether the cost will be cheap enough for us to be able to afford to extract it. If the oil is too expensive to extract, the shortage of oil seems to cause a recession, similar to what we are having now.
Scientific American's Path to Sustainability: Let's Think about the Details

Ugo Bardi

"Peak Civilization": The Fall of the Roman Empire
A post attempting to apply system dynamics to the fall of the Roman Empire which - as far as I know - has not been done, so far.
Cassandra's curse: how "The Limits to Growth" was demonized
With its scenarios of civilization collapse, the book shocked the world perhaps more than Cassandra had shocked her fellow Trojan citizens when she had predicted the fall of their city to the Achaeans. Just as Cassandra was not believed, so it was for the "Limits to Growth" which, today, is still widely seen as a thoroughly flawed study, wrong all along.
The Universal Mining Machine
Why can’t we build a universal mining machine here, on Earth, and stop worrying about running out of mineral resources?
Mind-sized Hubbert
What is it, exactly, that causes production peaks for oil and for other non renewable resources?
The dark side of coal - some historical insights on energy and the economy
In this post, I start to tell the story of coal in Italy and how the fortunes of the country went in parallel with those of coal well until mid 20th century.
The church, the peak, and my old watch
A post about leaving something that lasts a long time and that doesn't need precious resources that can't be replaced.
The post-peak car
A fantastic account of how a 1970s Fiat 500 has been retrofitted with batteries and an electric motor to create the Post Peak Car.
How to Drive your Elephant - Dealing with Complex Problems
How elephant driving may be seen as as a metaphor for controlling complex systems.
Peak Minerals
A post taken from a report co-authored with Marco Pagani which examines the world production of 57 minerals reported in the database of the United States Geological Survey (USGS) and makes the case for the peak and decline of many of these minerals in the near future.
Peak Caviar
"Peak Caviar" is another confirmation of how common the "Hubbert" behavior is. It doesn't matter if a resource is theoretically renewable, as sturgeons and whales are. If sturgeons or whales are killed much faster than they can reproduce, then they behave as a non renewable resource; just as crude oil.

Arthur E. Berman

Arthur Berman talks about Shale Gas
McMoRan Davy Jones Gas Discovery
Co-written with Joshua H. Rosenfeld, this post looks at a significant discovery in the U.S. Gulf of Mexico by the McMoRan Exploration Company that may contain 2-6 trillion cubic feet (Tcf) of natural gas reserves.
Shale Gas—Abundance or Mirage? Why The Marcellus Shale Will Disappoint Expectations
Shale gas plays in the United States are commercial failures and shareholders in public exploration and production (E&P) companies are the losers. This conclusion falls out of a detailed evaluation of shale-dominated company financial statements and individual well decline curve analyses.
BP Macondo Blowout - Static Top Kill vs. Bottom Kill: Weighing the Risks
A post co-written with William Semple.
Is the Drilling Moratorium Long Enough? No, Not Really
The key issues around the drilling moratorium as I see them.
What caused the Deepwater Horizon disaster?
The blowout and oil spill on the Deepwater Horizon in the Gulf of Mexico was caused by a flawed well plan that did not include enough cement between the 7-inch production casing and the 9 7/8-inch protection casing. The presumed blowout preventer (BOP) failure is an important but secondary issue.
ExxonMobil’s Acquisition of XTO Energy: The Fallacy of the Manufacturing Model in Shale Plays
Most analysts believe that the ExxonMobil acquisition of XTO Energy (XTO) represents a dramatic shift in strategy by the premier exploration and production (E&P) company, and a validation of shale plays. It is neither. The move represents a considered and deliberate choice that acknowledges diminished opportunities for the oil giant to add and replace reserves.

The Thermodynamics of Local Foods
I wrote this in response to a slew of media attention that argued against local foods. However, based on thermodynamics, only a predominantly local food system will be sustainable in the long run.
Ecological Economics and the Food System
This is a summary of energy use in the U.S. food system placed in the context of ecological economics. Our current food system is structured inappropriately for long-term viability, and the kinds of shifts required to make it more enduring are discussed.
Save it for the Combine
Few people understand how critical certain technologies are to their survival and way of life. The combine allows one person to harvest the food for hundreds, saving enormous labor while using liquid fuels. I argue that any rationing of liquid fuels or use of biofuels be prioritized for the combine.
The Food System and Public Policy
Many in the U.S. like to think we live in a free market economy. But when it comes to development of the food system public policy explains much of what we see.
The Food System and Resilience
Resilience is a concept from ecology that can be applied to any complex system. When the current food system is examined using a resilience framework it is found to be very fragile. The essay concludes by outlining the possible emergence of more resilient food systems given new economic and energetic realities.
Energy Descent and Agricultural Population
This article includes a graph that combines data on energy use and percent rural population, showing that more energy in a society lowers the proportion engaged in farming. Given the shape of this relationship, can we make some educated speculations about shifting labor demographics in highly industrialized nations during energy descent?
Scenario 2020: The Future of Food in Mendocino County
I believe there’s the possibility of a near-term collapse of complex societies given a financial shock, perhaps precipitated or exacerbated by political and energy crises. This photo essay conveys this potential from an imagined future, with an emphasis on the food system.
I have an interest in economics, in the broad sense, of how and why people and societies chose to invest and consume, and what this means for resources and the environment. The following three essays share a common theme: resources are only constrained in a world with exponentially growing demand for more stuff. Reducing demand is more important than increasing supply, and ultimately we have no choice. However, conscientious curtailment comes up against both engrained pyscho-social reward systems, which are largely explored in the first two essays, and the structure of our financial system, which is touched upon in the third.

Analysis of Decline Rates
This post offers a kind of reverse engineering of what numbers could be behind the long and detailed IEA decline analysis in their last report (2008 IEA WEO). A tentative decline structure for the post-peak Super-Giant and Giants oilfields is offered as well as a possible scenario for future production.
Peak Demand or Peak Consumption? A Look at OECD Oil Demand
In this post I show that the key driver behind the oil price increase since 2002 has been excess demand combined with unresponsive supply.
Peak Oil Update - July 2009: Production Forecasts and EIA Oil Production Numbers
An update on the latest production numbers from the EIA along with graphs/charts of different oil production forecasts.
Estimating the World Production Decline Rates from the Megaproject Forecasts
Having a good estimate of the decline rate of the resource base (most estimates are ranging between 2 and 6%/year) is fundamental for the precision of supply forecasts derived from megaproject database.
Saudi Arabia: An Attempt to Link Oil Discoveries, Proven Reserves and Production Data
This article is an attempt to apply the Hybrid Shock Model (HSM) on Saudi Arabia's oil production. In a nutshell, the HSM is trying to model the observed production profile from the discovery curve by simulating the different phases involved in the development of oilfields (initial discovery, planning, build, maturity).
Why We (Really) May Have Entered an Oil Production Plateau
We know that some countries (around 56) have seen their production peaked (also called type III depletion). The remaining group consists of 17 countries that have the potential to grow or maintain their current production (the type II group). I propose to apply the HL technique only on the total production from the the type III group and try to assess the future production decline coming from that group.
An Update on Mexico's Oil Production--The Rapid Collapse of Cantarell by the Numbers
Last year, I expressed my concerns about the eventual impact of a rapid collapse of Cantarell on Mexico's oil production. The last production numbers from PEMEX seems to confirm the rapid decline of Cantarell as well as the inability of the Mexican to rapidly bring new production online.
The Loglet Analysis
Most peakoilers on this site have been introduced to the logistic curve through the famous prediction of King Hubbert on the Lower-48 production. Fewer maybe knows that curve fitting techniques have been extensively applied by people that we may qualify as cornucopians. Ironically, the logistic curve is also used as a prediction tool for market share and technology substitution.
A Different Way to Perform the Hubbert Linearization
A quick post about a different manipulation of the logistic differential equation. By using the first derivative, we get a new way to perform the Hubbert linearization. Some results are given on Norway and the US oil production.
Norway and the Parabolic Fractal Law
Norway can be considered as the poster child of the Hubbert curve modeling approach with a production profile that is remarkably close to the logistic curve.

Concentrating On The Important Things - Solar Thermal Power
While we spend a lot of time talking about traditional energy sources based on depleting resources that are extracted from the ground, I think its important to remember that the fastest growing sources of energy are solar and wind, and that these will never run out.
Tapping The Source: The Power Of The Oceans

Locabucks: Are local currencies a way to escape the liquidity trap?
I look at the concept of local currencies (or "locabucks" as I'm now dubbing them), an idea which has its roots in the Great Depression as a mechanism for escaping the liquidity trap - and thus might be relevant again in the not-too distant future if present trends continue.
Terra Preta: Biochar and the MEGO Effect
In this post I have a look at modern day techniques to produce terra preta (often called biochar or agrichar) which have the potential to increase soil fertility, generate energy and sequester carbon all at the same time.

From the Editor's Desk: Peak Oil, Heretical Thought, Complexity, and the Future of The Oil Drum
Lately, I have been thinking a lot about the direction of The Oil Drum. Much of my thinking on this set of ideas has been brought about by some soul-searching, trying to understand the problems we face as a community, and then figuring out how to "positively push the future."
Peak Oil, Persuasion, and the World Meme
What insights can we claim from psychology to get those we care about, and even those we don't, to dig deeper to get to an understanding of the pillars of the problems we face, instead of trying to buy aluminum siding for a house slowly falling in on itself?
Will Canada Fuel Fortress America?
Will Canada complacently allow the US to pillage her resources as energy supplies become more scarce?
Why the US Political System Is Unable to React to Peak Oil: Institutions

International Energy Agency calls 'Peak' on OECD Oil Demand
In World Energy Outlook 2009, the International Energy Agency seems to have dropped a bombshell that has been quietly (and politely) ignored.
The Economics of Volatile Oil Prices
Considering the fundamental nature of oil supply and demand provides a coherent explanation not just for the rapid rise in oil prices, but also the dramatic fall.
The 2008 IEA WEO - Oil Reserves and Resources
Despite significant changes, the 2008 IEA report still relies on inflated estimates of reserves from OPEC countries, overplays the contribution of reserves growth due to technology and predicts the reversal of a decades long trend of declining oil discoveries.
Oil, House Prices, Credit? Three parts of the same story
The long forgotten 'oil crisis' of just a few months ago has been replaced by a full blown 'credit crisis' - related events that represent the unravelling of half a century of unsustainable trends in oil consumption and debt.

Lies, Damned Lies and Government Oil Production Forecasts?
Back in 2005 the Norwegian Petroleum Directorate (NPD) forecast 2.84 mbpd oil production in Norway during 2009. I pointed out their forecast was rather optimistic. 2.3 mbpd was what actually came to pass. The NPD were 23% too high.

EROI, Insidious Feedbacks, and the End of Economic Growth
In this post I attempt to answer the following question: Is a return to long term economic growth possible?
The True Value of Energy is the Net Energy
"The true value of energy to society is the net energy, which is that after the energy costs of getting and concentrating that energy are subtracted.” - H.T. Odum (1973)
Energy Transitions and the Next Paradigmatic Image of the World
The most important question is “what is the next paradigmatic image of the world?”
The Net Hubbert Curve, what does it mean?
Cutler Cleveland of Boston University has reported that the EROI of oil and gas extraction in the U.S. has decreased from 100:1 in the 1930’s to 30:1 in the 1970’s to roughly 11:1 as of 2000. What does this mean?
Further Evidence of the Influence of Energy on the US economy
Gail, Jeff Rubin, and now James Hamilton of the University of California – San Diego have produced literature correlating either this financial collapse or recessions more generally with peak oil and oil prices. The take-away message of their work is that oil prices played a fundamental role in causing the current recession and many previous recessions.
The Energy Return on Investment Threshold Due to the asymptotic nature of the curve at high EROIs, extraction/conversion processes with EROIs below 8 result in vastly different flows of net energy than those with higher EROIs.

Countdown to $200 oil meets Anglo Disease
Oil has played a fascinating side role in my Anglo Disease series, allowing the debt bubble to go on for much longer than expected. But now, instead, it is accelerating the crash. Let me take you through the whole cycle.
Fierce pride - yes it works! (or, first ever bank-financed offshore wind farm inaugurated!)
A post about the windfarm which I helped finance two years ago which is now up and running.
Countdown to $200 oil: $140 oil and speculation
There are A LOT of good reasons why oil prices are going up. Let me show you just a few.
The cost of wind, the price of wind, the value of wind
In this post I try to clear some of the confusion that surrounds the economics of wind power, as this is an issue that is often used by the opponents of wind to dismiss it.

4%, 11%, Who the Hell Cares? A very early piece pointing out that the post-peak decline rate is really the critical variable in assessing the seriousness of peak oil - much more important than the date or height of peak, or the degree of warning of peak. This piece still seems pretty good to me.
Hubbert Theory says Peak is Slow Squeeze. The first piece I wrote looking at the evidence that the post peak decline rate will probably be slow, rather than rapid.
The Auto Efficiency Wedge A piece looking at the fact that at slow decline rates, it's reasonably forseeable that peak oil can be handled by ongoing efficiency improvements (not painlessly, but without complete disaster)
Depletion Levels in Ghawar A major forensic analysis of the state of oil depletion in the Ghawar field of Saudi Arabia, suggesting that Saudi official oil reserve figures are over-optimistic.
US Peak Oil Adaptation: Prognosis in a Credit Crunch Rather prescient piece from 2007 discussing the possibility that the credit crunch could collapse oil prices and slow adaptation to peak oil. This turned out to be pretty much what happened.
Fermenting the Food Supply An argument against continued growth in biofuel consumption as an alternative to oil, on the grounds that the implications for food prices are likely to be very problematic.
The Fallacy of Reversibility This piece argued that there is no evidence for the idea that peak oil will lead to a revival of local non-industrial agriculture. The reverse seems more likely - that industrial agriculture is being and will be strengthened by high oil prices.
Powering Civilization to 2050 The first of three posts laying out a scenario for how we could get to a fairly close to carbon neutral civilization by 2050, without major collapse or disaster (if I was in charge in of the world). This post looked at energy, and argued that extrapolating the learning curve of solar power, it was possible to see energy becoming cheap again by 2050, based primarily on solar.
Four Billion Cars in 2050? Second of the "2050" series: Guesstimates on how many cars there might be by 2050, and how they might be powered.
Food to 2050 The third in the "2050" series: Whether there are likely to be limitations on feeding the world's population to 2050 in a cautiously optimistic scenario.

Theory of Geopolitical Disruptions to Oil Supply
Discusses several non-geological feedback loops that may have a dramatic impact on the course of resource depletion.
Mexico, A Nation-State Dissolves
Addresses the geopolitical instability in Mexico as a potential bellwether for the Nation-State structure generally, and its potential impact on oil production and exports.
The Problem of Growth
How the fundamental structure of our civilization demands perpetual growth and is therefore inherently unsustainable, as well as potential structural solutions.
Oil Demand Destruction and Brittle Systems
Argues that demand destruction tends to make remaining demand less elastic, and therefore makes systems more brittle and vulnerable to future supply shocks.
Predator-Prey Dynamics in Oil Prices
Argues that oil demand, supply, and prices can be modeled similar to predator-prey systems in nature.
