Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society. Rather, it is the scientific conclusion of the best paid, most widely-respected geologists, physicists, and investment bankers in the world. These are rational, professional, conservative individuals who are absolutely terrified by a phenomenon known as global “Peak Oil.” David Ross interviews Dr. Richard Heinberg
How important is oil to industrial societies?
HEINBERG: It’s about as important to industrial societies as water is to fish. The industrial revolution was, basically, all about fossil fuels. Coal came first, but when oil was harnessed, humankind discovered the cheapest, most abundant source of energy ever. As a result, we’ve increased our human population from just a few hundred million at the start of the industrial revolution, to over six billion, three hundred million now. We’re adding about a billion people every 12 years at current rates. This is something that’s never been seen before. We’ve added more people since 1999 than existed in the world just a few hundred years ago. This is an indication of the incredible impact that fossil fuels have had on human societies.
Additionally, we’ve invented all sorts of technologies to take advantage of this energy subsidy through transportation, communications, manufacturing, etc. Machines now do things that were formally done by human or animal muscle power. We also do all sorts of things with machines that we didn’t do at all before. So fossil fuels have changed our way of life, our view of the world, how many of us live on the planet, how we live, and where we live.
*You talk about the Hubbert oil curve and its implications? *
M. King Hubbert was the first geologist to make a fairly accurate estimate of the total recoverable quantity of oil—first in North America and then later in the world as a whole. He was also the first petroleum geologist to understand the principles of oil depletion.
Hubbert realized that, for any given oil province, when about half the oil is gone, production tends to peak. The reason is that we naturally go after the easy, cheap oil first and, by the time about half of the total amount of oil is gone, the easy stuff tends to run out; then it becomes more difficult to extract what’s left.
So there’s a bell-shaped curve to production that seems to apply across the board. Economic and political factors can change the shape of that curve. If there’s a war or the price of oil changes, or a country voluntarily decides to restrict exports, those can alter the oil extraction profile. But even so, what goes up must eventually come down and so depletion can be mathematically modeled even if the graph is fairly bumpy.
When Hubbert applied his methods to the United States, which was the world’s foremost oil producing nation for many decades, he determined that the halfway point of extraction would occur around 1970. Sure enough, just as Hubbert predicted, US oil production peaked in 1970 and it’s been going down ever since. We’re extracting about as much conventional onshore oil in the US now as we were in 1940, which is much less than was being extracted in 1970, and that’s the reason we’re more and more dependent on imported oil from places like Saudi Arabia, Venezuela, and Iraq.
Using Hubbert’s method, it’s also possible to predict when global oil production will peak. The scary thing is, the peak is likely not that far off. No one is absolutely sure, because it is impossible to determine exactly how much oil is yet to be discovered. Some countries have political motives for underreporting or overreporting their reserves. But the best guesses are that we’re only a few years away from the global oil production peak.
*What will happen when we pass the peak of the Hubbert oil curve? *
Once we hit the peak, every year thereafter we will be unable to find and pump more oil. If the demand continues at the present rate or grows, the supply will be inadequate and that will have tremendous economic implications for the whole world. Either we have to find other energy sources to make up for what we lose from petroleum as it begins to run out or else we will go into permanent economic decline with vast implications for the economy, food production, transportation, and so on.
Can we find alternative energy sources in time to replace oil?
That’s a surprisingly tough question because there are very few scientists out there who are doing good comparative studies of the various energy alternatives. We have companies that are invested in particular energy alternatives, that are doing their own studies, but they understandably have a certain bias. What we need are objective studies comparing the alternatives on the basis of a series of clear, transparent criteria, like:
Are they renewable?
What’s their environmental cost?
What’s their energy profit ratio?
You see, it takes energy to get energy. It takes energy to drill an oil well. It takes energy to manufacture a photovoltaic solar panel. But the energy profit ratio is different for each of the alternatives and that figure needs to be objectively determined. Suppose we were to invest $100 billion dollars over the next ten years in making a transition to a hydrogen economy and then discovered that, in fact, hydrogen has a lot of hidden costs. Well, we can’t afford to lose ten years and $100 billion dollars going down the wrong road at this point.
*Are there alternatives that can replace oil? *
We don’t know for sure, but there’s little cause for complacent assurance right now. The reason I say that is that most of the renewable alternatives like nuclear, wind, and solar have various drawbacks.
Nuclear power is expensive and dangerous and the problem of radioactive waste storage has not been solved.
With wind, you can only place turbines in certain places. (Wind is probably the best of the alternatives, in my view.) With solar, the sun only shines part of the day and some regions are often cloudy. Photovoltaics, right now, are still quite expensive and not very many people are willing to make the investment.
Hydrogen is not even an energy source; it’s just an energy storage medium. Yes, we could run cars on hydrogen, but where are we going to get enough hydrogen to run millions of vehicles?
Either it has to be made from fossil fuels—which are the source of nearly all commercially available hydrogen today—or from water using electrolysis. But making hydrogen from water takes more energy in the form of electricity than the hydrogen will give you later on.
Again: Where will we get all of this extra electricity?
Are we going to get it from nuclear, solar, or wind? If we choose any of these alternatives, it means dramatically increasing our energy budget for electricity production at a time when we’re going to be suffering from the economic effects of petroleum and natural gas depletion.
We’re not prepared to make a huge investment in new electrical generating capacity now and we will be even less prepared then.
How does human carrying capacity fit into the context of the Hubbert oil curve?
We have artificially increased the carrying capacity for human beings on planet earth. Carrying capacity is how many individuals of a given species can be supported by the environment. That number tends to vary, depending on weather, rainfall, etc. Carrying capacity changes for just about every species from year to year.
Human beings have found a way to artificially—and probably only temporarily—enlarge our carrying capacity with industrial agriculture, expanded transportation networks, technology, better sanitation, better medical care, etc.
The problem is that this expanded carrying capacity is dependent on a non-renewable resource, namely, fossil fuels. So this is not permanent carrying capacity that we’ve created; this is what William Catton—who wrote the book Overshoot, in the 1980s—called phantom carrying capacity. It’s carrying capacity that may vanish as fossil fuels disappear from our lives.
What’s the size of that phantom carrying capacity? Nobody knows for sure, but if we look back to how many people planet Earth supported before we started using oil, we find it was fewer than two billion. We now have over six billion.
So, even granting that we’ve discovered ways of keeping people alive through better sanitation and so on, ways that might be sustainable using relatively little energy, the fact is that we’ve probably overshot our carrying capacity and we may need to find ways to reduce the human load on the environment if we’re all going to survive.
*Can you talk about the different options for our future as we pass the peak of the Hubbert curve? *
Plan A, what I call Plan War, is what we’re pursuing right now. Whoever has the most guns and bombs will compete with everyone else for the remaining resources and use them till they’re gone.
Of course, the situation is a bit more complicated than that. Obviously, the US didn’t conquer Iraq so that we could literally build a pipeline directly from Basra to Houston. I think the US has economic and geopolitical reasons for wanting to control the price of global oil. Iraq is a pivotal country in terms of the future of oil production. It has the second largest reserves and it’s between Saudi Arabia and Iran.
Saudi Arabia has the largest reserves, but it’s politically unstable and it’s unclear what would happen in Saudi Arabia if the government there were to fall. Having a large military presence next door to Saudi Arabia must make a lot of sense in the minds of the geostrategists.
So that’s Plan A and it doesn’t look like it’s going to have a very happy ending because one can foresee more and more armed conflicts between heavily militarized consuming nations and poorer resource-rich producer nations. Eventually, there will be conflicts between competing consuming nations. China, for example, wants to industrialize. China is using more and more oil every year.
But if global oil production peaks, that means the Chinese will be in direct competition for every barrel of oil with the already developed countries like the US So how are we going to work that out? Using nuclear bombs? I hope not, but right now I don’t see any other thinking going on.
Plan B, what I call Plan Powerdown, would entail some kind of national and global process for deliberately reducing our dependence on fossil fuels.
It would require changing our economy so it’s no longer a growth economy. It would require dealing with population issues, so that we’re putting less of a load on existing resources. It would require dealing with the problem of economic inequality within and among nations because the more economic inequality we have, the higher the likelihood of conflict.
Powerdown would require changing our whole way of life, going from a consuming society to an efficient society, going from a growth society to a society that’s steady-state and even reducing its scale year after year. That’s politically very difficult. The last person to attempt something like that, in this country anyway, was Jimmy Carter—and look what happened to him when a political opponent came along promising a return to times of plenty. Still, if in the US, people realized what’s at stake and what the long-term consequences of their path will be, I think many, if not most, would be interested in following Plan B.
Plan C, what I call Plan Snooze, entails doing little or nothing while the problem is temporarily denied or wished away.
There are all sorts of people assuring us that the market can take care of any resource shortages. Or that all of the intelligent people working on the problem will surely come up with an easy solution. Or that we will see an effortless transition to a hydrogen economy.
If you watch television and read the newspapers, you will see that this is a popular message. It’s what the corporations are telling us and it’s what we all want to hear.
Unfortunately, the problem with Plan C, as far as I can tell, is it’s probably wishful thinking. Then the only option we will likely have left is military confrontation over the remaining resources.
