Here's what you may not know:
The amount of oil we can take from the ground each year is about to reach a limit that cannot be increased by ingenuity or determination. That limit will then decrease forever, with short plateaus and little upward bumps on the way down. A similar limit for natural gas will follow in a few years.
The act of taking oil or gas from the ground is called producing it. Since the start of oil production in the nineteenth century, the world has produced close to half of its ultimately recoverable oil resource. At the half-way point, the world will achieve its production peak -- more oil will be produced in a year near the half-way point than ever before or ever after. This statement follows from a regularity of oil production statistics first observed by M. King Hubbert. If we consider a large enough number of oil fields, their aggregate production rate will display a characteristic curve. The group of fields will reach a peak rate of aggregate production when half of the ultimately recoverable oil has been produced. After the half-way point, the physical properties of oil reservoirs and the variation of the dates of discovery of the fields will cause the aggregate rate of production to slow progressively until all recoverable oil has been produced. Hubbert used this regularity of oil field statistics to predict corrrectly that the lower 48 United States would produce half of their ultimately recoverable oil resource by 1972, and that production from the lower 48 states would, consequently, peak in 1972.
Jean Laherrère is a well known petroleum engineer and analyst of the world's oil reserves. He forecasts oil production by comparing discovery records with production records, and by exploiting the principle that oil cannot be produced until it has been discovered. Here's a figure from Forecasting future production from past discovery. It predicts a startling rate of decline of our oil supply between 2010 and 2050.
The price of oil and gas will not signal shortages until the decline is upon us. For many years after the peak we will have progressively less energy at progressively higher prices. This contradicts our usual expectation that rising prices will quickly result in greater supply. Higher prices, no matter how high they are, will not create enough new supplies of transportation fuel to prevent sustained contraction of the economy. The resulting paradoxes will create confusion in an economy that depends on economic growth, believes in economic growth, even worships economic growth. The economy will contract every time fuel prices rise sharply, knocking the price of fuels down as recession reduces demand for them. An unregulated market will not invest large amounts of fuel in the deployment of alternative fuels in these circumstances. Nor will an unregulated market make the "uneconomic" investments needed before the peak to prevent being caught in such cycles. Governments must compensate for this deficiency of the market. They must acknowledge the peak of oil and gas production, and introduce appropriate market incentives ahead of the peak.
Those who most need to understand the function of energy in our economy don't. Energy differs from other commodities. Nothing can be done without energy. Nothing can be moved, built, manufactured, planted, fertilized, harvested, or mined, without the liquid transportation fuels that petroleum provides so well, and for which no competitive replacement has ever been found. As a consequence, new energy sources require large investments of energy itself. In particular, the energy investments needed to obtain alternative energy sources and fuels are not only large, but they are much larger than the energy investments needed to obtain fossil energy. These energy investments are so large that some forms of alternative energy will never serve as primary sources of energy. For example, solar electricity from photovoltaic cells will not provide enough energy for the mining, manufacturing, transportation, transportation infrastructure, installation, transmission infrastructure, maintenance, and decommissioning required by the existence of the solar cells. This is not a question of building more solar cells. The ratio of energy returned to energy invested is too small. Solar cells don't work as a primary energy source, although they have other uses. Similarly, ethanol from corn doesn't work as a primary energy source, although it has other uses.
These properties of energy as a commodity invalidate a fundamental assumption
made by economists. Rising prices will not result in the smooth
substitution of alternative sources of energy. The large energy
investments needed by alternative energy sources, and the smaller energy
output produced by them, will mean that alternative energy sources will
not fully compensate for the decline of oil and gas. Progressively less
transportation fuel will be available for use outside of energy production.
In spite of our best efforts, the world's economy will contract for many
In addition to their failure to understand energy, and the other factors described by Fleming, I believe there is an ideological explanation for the failure of mainstream economists to acknowledge what is about to happen. Government direction of markets will be needed to mitigate the damage the post-peak decline will cause. Any new or restored regulation of markets by governments is offensive to free market dogma. The free market fundamentalists are in the driver's seat. They reflexively deny the reality of problems that require collective action. Perhaps only an economic crash will knock them out of the driver's seat.
Although I prefer to create awareness than propose solutions, certain measures seem obviously necessary.
Government, funding institutions, and universities must promote study and understanding of the function of energy in the economy. Government policy workers must allow an understanding of the function of energy to permeate their view of the world.
Energy conservation, from better insulation to fuel efficiency, must be encouraged and mandated by government as an investment in a more appropriate infrastructure for the difficult times ahead.
The prospects for alternative transportation fuels are not promising. Fundamental problems have not begun to be solved: providing the energy to manufacture the alternative fuels and the infrastructure to distribute them. Governments must start encouraging radically more efficient transport for freight and passengers--railways, for example.
In North America, we should stop using natural gas as a fuel for new electricity generators, or for upgrades to existing electricity generators. Although its lower CO2 emissions are attractive from an environmental perspective, North American natural gas will soon disappear. We must reduce our reliance on natural gas now, or at least stop increasing our reliance on it, or face much more serious disruption than necessary. We must reconsider coal and nuclear generation of electricity, looking for ways to make them more acceptable environmentally. We must provide at least as much economic incentive for wind and solar as for oil and gas.
None of these measures will prevent a great reduction of consumption, but may prevent serious social disorganization. We need to figure out how to retain social cohesiveness while going through the reduction.
