Is it True that Non-Renewable Resources are Finite?
KINGSTON, ON, May 22, 2011/ Troy Media/ – Let me begin by saying that I believe the premise of this question is mistaken. It is quite incorrect to think that fossil fuel resources are finite. It may be true that there is a finite quantity of such resources in the earth’s crust, but that does not mean that we will ever run out. Indeed, I would be willing to place a bet with anyone in this room that human beings will cease using fossil fuels long before we have exhausted the available resource and that this is completely independent of any policy designed to speed up the invention and distribution of alternative “green” sources of energy.
Why? Because human intelligence and ingenuity have consistently and repeatedly unlocked technological and scientific advances that have raised the standard of living of each generation compared to its predecessor, while increasing the ability of human society to support larger numbers of people and increasing the carrying capacity of the planet.
Thomas Malthus earned economics the nickname of the dismal science in the 18th century by observing that the population was growing faster than the food supply. He predicted mass starvation.
In the 1970s, the Club of Rome predicted massive shortages of natural resources due to overconsumption and overpopulation, with disastrous effects on human health and material well-being.
In 1980, the Global 2000 Report to the President, wrote: “If present trends continue, the world in 2000 will be more crowded, more polluted, less stable ecologically, and more vulnerable to disruption than the world we live in now. . . . Despite greater material output, the world’s people will be poorer in many ways than they are today.”
The reason why the ecosystem hasn’t collapsed, why we haven’t run out of oil, why we are still successful in feeding ourselves, why incomes are rising and health status improving around the globe is that the doomsayers have completely misunderstood the way the world works.
Of all their misunderstandings, two stand out. They don’t understand what natural resources are. And they don’t understand that the greatest natural resource of all is the human mind.
It may be popular, but it is quite incorrect, to think of natural resources as not only exhaustible, but on the verge of being exhausted. If, for example, natural resources were actually getting scarcer, then the price would go up. That’s part of what prices are for, to signal shortages and availability and to trigger exploration and innovation where required.
But the price of natural resources has been steady or else in decline for centuries, although the recent entry of developing countries like China into the marketplace may have moved natural resources prices temporarily to a higher level, not because of shortages, but because of China’s fondness for old-fashioned and highly inefficient mercantilism.
Remember the famous bet between ecologist Paul Ehrlich and economist Julian Simon. Simon bet Ehrlich that the prices of any five natural resources Ehrlich chose would drop over a 10 year period, whereas Ehrlich, inspired by the Club of Rome, was convinced that we were on the cusp of huge shortages driven by overconsumption and population growth. Ehrlich paid up in 1990.
Ehrlich, like his many forerunners and successors, forgot that shortages and rising prices are an opportunity. Malthus didn’t foresee that farmers could become hugely more productive in response to rising demand for food, eventually unleashing the last century’s Green Revolution. Aquaculture, hydroponics, genetic modification and other technologies will allow us to keep feeding the world’s population, probably at a declining real cost in the long haul.
What happens when you mix ideas and natural resources
Thus, because of human ingenuity, the “carrying capacity” of the planet is not a fixed quantity, but a hugely variable one, depending on how much of our intelligence we mix with the natural world. Put another way, we could say that the availability of natural resources is not determined merely by the quantity of such resources in the earth, but by the interaction between such resources and our ability to squeeze more value out of them.
We now require less and less land to feed each human being. We need less and less steel for each car and copper for each telephone connection and gasoline for each mile travelled than we ever did before. Those resources are valuable, and it makes no sense to use more than the minimum necessary in each instance. And that minimum is falling all the time, because it pays to make it fall. When things get in short supply, human ingenuity comes up with cheaper alternatives, or invests time and intelligence in increasing the supply, both of which ease the shortage.
Just one example: the telephone. Look at pictures of cities early in the last century; you’ll see a forest of utility poles carrying hundreds of copper wires to connect telephones to each other. Copper is a non-renewable natural resource. If we had had to run that many wires to connect every person, it is perhaps possible that it would have been beyond the limit of our planet’s copper resources.
So, of course, now that billions of people are connected to the telephone, the price of copper has skyrocketed and the extension of telephone service to the billion plus people who have never made a telephone call has now stopped, right?
Wrong. In fact the long term price of copper has been stable or falling for years, overhead wires are rapidly disappearing, and those cables that do connect us are usually fibre-optics, made of cheap and plentiful materials like sand, and those materials carry literally millions more bits of data per second than the old copper wires.
Moreover, we have developed a whole wireless technology that is not connected to the network by any physical object at all, and satellites carry many of the signals between cities and countries. We are vastly extending the reach of the telephone with fewer and fewer resources consumed because the price mechanism allows us very successfully to balance supply and demand over the long term, regardless of the short term gyrations we may experience.
Human creativity’s influence on “finite” resources
I intentionally used a non-energy example, but I’d like to now talk about oil and gas. Remember that the doomsayers of the 1970s that I quoted earlier thought we would have run out of oil by today because they compared knowledge about the state of supply then with then current rates of consumption and concluded that those available supplies would be exhausted in very short order. But the fact of the matter is that we have consumed 40 more years worth of oil and yet find ourselves with more reserves than we believed we had in 1970.
How is that possible? Because the supply of oil isn’t a function of the amount in the earth’s crust. It is a function of capital investment, which simply symbolises the application of human intelligence to the problem of finding the oil we need.
You might believe that the extra reserves that now exist are due chiefly to new discoveries of oil deposits, but you would be mistaken. The majority of new supply has come and will continue to come, from wringing more supply from already known reserves through various kinds of enhanced recovery techniques.
The oil sands are a classic example. A few short decades ago people knew that the oil sands existed, but the oil they contained was not accessible from a technological point of view, or the technology was too expensive to use when compared to more conventional sources of oil. But as the result of the application of human ingenuity and financial capital, we have shifted the oil sands from theoretical but non-recoverable reserves into recoverable ones. And my understanding is that at current prices and technology, we can only recover 10 per cent of the oil in the oil sands. Yet that 10 per cent is enough to make Canada’s brand new reserves the second largest in the world. All we have to do is to increase the recovery rate from 10 per cent to 20 per cent, and we vastly increase again the supply of oil available to humanity, with no increase in the quantity of oil in the earth’s crust.
The price mechanism does quite a good job of smoothing consumption out over time while matching supply and demand today. And part of the assumptions behind oil prices include reasoned views about the future state of oil supplies. If there was genuine evidence of looming and irremediable oil shortages, prices would rise to allow us to shift oil consumption into the future, where those future shortages would make it more valuable. But generally speaking these are not necessary, in large part because of the well-established and well-functioning system that we have for increasing the available supply of oil over time, a system I have been describing here. Thus the notion that the oil price somehow ignores an alleged future oil shortage is quite mistaken. One of the factors that oil prices most definitely reflect is all available knowledge about future supplies.
Prices, hydrocarbons and climate change
What about the idea that the burning of fossil fuels generates harmful side effects in the form of CO2 and other greenhouse gases that may be causing climate change, and that the oil price therefore does not reflect the true costs created by the consumption of such fuels?
I regard this proposition as quite reasonable. If we did make people pay the full cost of fossil fuel use (including environmental damage) then that would establish a better balance between the benefits of oil consumption (such as a rising standard of living) and the costs, which include environmental degradation.
But people have a tendency to vastly overstate what we actually know about unaccounted-for social and environmental costs of hydrocarbon consumption. According to one well-known economist specialising in the economics of climate change, a considerable amount of work has gone into estimating potential economic consequences of global warming induced by greenhouse gas emissions. The following points emerge from this analysis.
The Stern Review was not, as many media sources claimed, a novel undertaking. It was number 211 in chronological sequence.
The Stern Review’s estimate of the marginal social costs of greenhouse gas emissions is far outside the mainstream view. It is even an outlier compared to non-peer reviewed studies that use low discount rates. It has been subject to extensive criticism by a large number of economists.
Average estimates of the marginal social cost of greenhouse gas emissions have declined over time.
The median estimate among peer-reviewed studies that use a 3 per cent discount rate (pure rate of time preference) is $20 per tonne of carbon. The mean is $23 per tonne.”
This is not in any way a negligible amount and is a matter worthy of the attention of policy makers. On the other hand, it is not such a large amount that it is likely to result in huge changes in the pattern of consumption of oil and gas.
But that tells us something important. Most of the alternatives to oil and gas are more expensive today, per unit of energy output, than fossil fuels, even ones bearing the full cost of the environmental damage they cause. So a policy of force-feeding the growth of these expensive technologies is a policy of declining human prosperity, because we end up paying more for energy than we need to, and the decline in our standard of living is greater than the benefit that we derive through environmental improvement.
Economic growth: Problem or solution?
By almost any measure of human well-being, the state of humanity has improved over the course of the last two hundred years, and, generally speaking, it has improved more in those two centuries than in the whole of the rest of human history, and this in spite of the fact that humanity’s numbers have grown hugely. And that improvement is almost all down to economic growth.
Since 1800, the global population has increased about six-fold. Manufacturing output, on the other hand, has increased 75 times in value. Total global economic product has risen more than 50-fold. And this increase in human wealth has improved the state of humanity throughout the world:
The average person’s life expectancy at birth has doubled, infant mortality is less than a third of what it used to be, and real income has grown seven-fold. Children are less likely to go to bed hungry and women are far less likely to die in childbirth.
Longevity in developing countries is higher today than it was in the world’s wealthiest economy, Britain, 100 years ago. People live longer in the developed world, but the developing world is improving faster.
Children are likelier to be at school than at work. People are more educated and freer to choose their rulers and express their views, as measured by a number of human progress indexes. Work is less physically demanding and people work fewer hours.
We generate far fewer pollutants per unit of GDP, and in fact the richer countries become, the cleaner their environment.
So economic growth is the key factor allowing us to reduce most of the problems facing humanity.
Now let’s put together a couple of the ideas I have been developing in this little talk: Natural resources are not getting scarcer but rather more plentiful. And because of cumulative economic growth, human beings are consistently better off with time.
So trying to fix the world’s problems by restricting economic growth will produce the opposite result, and will result in a regressive transfer of wealth from the less well-off (today’s population) to the better off (future generations).
Such proposals to “progress” by reducing our standard of living are based on the notion that human prosperity and well-being are an illusion, subtracted from the productive capital of the Earth. But this is wrong. Human beings add something crucial to the world. They add their intelligence to it.
It is not that we do not face problems and challenges. Of course we do. But we cannot stop with the identification of problems, we must also look at the mechanism we have successfully used to solve every one of the significant challenges that humanity has faced since the dawn of time: the human mind.
The wealth of humanity comes from mixing natural, human and financial capital in differing proportions, and as natural capital becomes scarce in one context or another, we invent ways to sustain it, supplement it or replace it. Thomas Malthus and his ilk are not wrong in having identified challenges facing the human race at specific moments in our history – they have simply misunderstood how the right human institutions, such as private property, the rule of law, contract, incentives and human intelligence all work together reliably to solve those problems, even when we cannot foresee with precision what the solution will look like.
If shortages in the future do occur, they will trigger price increases in the supply of oil and gas, which in turn will provide huge incentives to find alternatives that are cheaper than the rising price of oil and gas. But that is a substantially different set of circumstances than today’s where the alternatives are generally more expensive, even when environmental factors are included.
