Oil Abundance? Not So Fast- A Risk Checklist
$this->bbcode_second_pass_quote('', 'E')NERGY, ESPECIALLY OIL, IS KEY TO THE ECONOMY
Nothing gets done without energy. The economy as a measure of real-world activity is based on energy and natural resource use, not finance. Whenever oil prices have risen sharply since the 1940’s, a recession has almost always followed. Attempts to manipulate the economy with fiscal and monetary policy cannot succeed if affordable real resources are not available. In particular, our water supplies and agricultural economy are very dependent on oil and other fossil fuels, while energy production requires a lot of water.
We have two energy systems, not one. Nearly all transportation around the world is powered by petroleum, and most petroleum is used for “transportation energy.” Other sources – coal, natural gas, nuclear, hydropower, wind, and solar – are mostly used for “process energy,” meaning electricity, heat, and manufacturing. Advances in the non-oil sector have done little to satisfy the demand for transportation energy.
High-priced oil tends to reduce other economic activity before slowing oil consumption directly, because there are few substitutes for oil. People do not drive 85% of the way to work, so they have to cut other spending to pay for expensive gas. The economic benefit from a gallon of gasoline or diesel is often greater in China and other developing economies than in the US and Europe, so they can afford to pay more than we can. Our economic growth has slowed when prices have risen rapidly, especially as oil prices exceed $100 per barrel.
Despite large increases in the price of gasoline, American consumption has remained nearly level at about 9 million barrels per day for the last ten years. Diesel consumption, the second largest use of oil, dropped briefly due to the economic slowdown, but has now fully recovered, growing since 2009.
THE COST OF OBTAINING OIL IS RISING
“Energy Return on Energy Invested” (EROEI) is an important concept showing how much energy (not just money) we get for the energy used in the extraction process. During much of the twentieth century, US oil extraction enjoyed an EROEI ratio of 50 or more, which meant that only 2% of the energy was consumed in the production process. Current estimates of oil from fracking and tar sands show an EROEI well below 10, which means we use 10% or more of the energy from that oil simply getting it out of the ground.
Low oil prices tend to reduce oil extraction, because the newest oil sources tend to be the most expensive – tar sands, tight oil, deepwater fields, and so on. If oil prices fall too far, investors will not get the return they need to justify new drilling efforts, so many new projects will be abandoned or delayed.
The rate of growth in conventional oil extraction around the world has slowed markedly since 2005, despite massive ongoing investments by oil companies in exploration and production efforts, because new oil is hard to find and hard to extract. Global oil extraction rates outside of the US grew only 3% in the eight years between 2004 and 2012, even though oil prices tripled during that period.
Another factor has reduced the amount of net exports of oil in world trade and thus contributed to higher prices: oil exporting countries often increase their consumption levels faster than extraction rates, and consumption may continue to rise even if extraction falls. China, Indonesia, Great Britain, Egypt, Vietnam, Argentina, and Malaysia have all changed from exporters to importers in the last twenty years increasing the competition for oil in world trade.
NEW SOURCES OF AFFORDABLE OIL ARE NOT AS ABUNDANT AS IS COMMONLY CLAIMED
