“Peak Oil” Less A Concern As Alternatives Reduce Demand

Researchers at Stanford report that “peak oil” — and the related fears that we have depleted the Earth’s supply of oil so much that we will run into greater conflicts between supply and demand that will stimulate social unrest and economic problems — are unwarranted. They conclude that the demand for oil – as opposed to the supply – will reach its own peak and then decline. The following new release is from Stanford Research (images added).
Stanford researchers say ‘peak oil’ concerns should ease
Should concerns about “peak oil” focus on demand for oil rather than dwindling supplies of it? Yes, according to a new analysis. Limits to consumption by the wealthy, better fuel efficiency and lower priced alternative fuels should begin driving down demand for oil around 2035. That’s good news overall, but policymakers should pay attention to the mix of substitutes that will replace conventional oil.
Fears of depleting the Earth’s supply of oil are unwarranted, according to new research, which concludes that the demand for oil – as opposed to the supply – will reach its own peak and then decline.
“Peak oil” prognosticators have painted pictures of everything from a calm development of alternatives to calamitous shortages, panic, and even social collapse as the world reaches its peak of oil production – and then supplies fall.
But according to the study by researchers at Stanford University and the University of California-Santa Cruz, those scenarios assume that an increasingly wealthy world will use all of the oil pumped out of the ground.
Instead, the historical connection between economic growth and oil use is breaking down – and will continue to do so – because of limits on consumption by the wealthy, better fuel efficiency, lower priced alternative fuels and the world’s rapidly urbanizing population.
“There is an overabundance of concern about oil depletion and not enough attention focused on the substitutes for conventional oil and other possibilities for reducing our dependence on oil,” said study co-author Adam Brandt, assistant professor of energy resources engineering at Stanford’s School of Earth Sciences.
The study, published in Environmental Science & Technology, describes a variety of mechanisms that could cause society’s need for oil to begin declining by 2035. Several earlier studies have suggested that passenger land travel has already plateaued in industrialized countries and is no longer hitched to economic growth. Passenger land travel now accounts for about half of the global transportation energy demand.
Even in developing countries, economic growth has been less oil-intensive than was seen in the West during the past century. China, for example, sells 20 million electric scooters to its citizens each year as part of the government’s policy to reduce air pollution. That exceeds total US passenger vehicle sales annually.
“We’ve seen explosive growth in car ownership in countries such as China,” said co-author Adam Millard-Ball, an assistant professor in the Environmental Studies Department at UC-Santa Cruz. “However, those cars will be more efficient than those of the past, and travel demand will eventually saturate as it has in rich countries such as the United States.”
Lower Oil Dependence
Freight and air travel have shown no such break from economic growth. Rich people may not drive more beyond a certain income level, but they do fly more and buy more belongings, as do people moving out of poverty. Even in air travel and freight, though, energy efficiency has begun to improve after decades of stagnation, lowering oil dependence, according to the new study.
“A major uncertainty is whether demand to move goods around the world will eventually saturate, as we’ve seen in the case of passenger transport,” said Millard-Ball.
Price-competitive alternatives to conventional oil are another factor behind the peak in demand. Competition comes from increasing quantities of fuel from oil sands, liquid fuels from coal, natural gas, biofuels, hydrogen, and electricity generated from renewable sources.
Technological advances and the high price of oil are helping such alternatives compete on price. In 2010, the world produced 1.8 million barrels a day of biofuels, six times the amount in 2000. In Argentina, natural gas fuels 15 percent of all cars, due to policies meant to favor the domestic natural gas industry.
The researchers did not try to forecast peak demand’s impact on oil prices. But even if oil prices spend much time above the historical upper range of $140 a barrel, the peak in demand will only come sooner than they forecast.
“If prices rise above their current levels for an extended period, we’re likely to see even more efforts to improve efficiency and exploit alternatives to conventional oil,” said Millard-Ball. “That would hasten the onset of a demand-driven peak.”
Impacts Of Alternatives
The new research, though encouraging, does not describe a transportation future free of worry. Instead, the researchers recommend a shift in attention to the various alternatives to conventional oil.
Policymakers should not rely on oil scarcity to constrain damage to the world’s climate. The alternatives to conventional oil emit varying amounts of greenhouse gases, while large-scale production of biofuels could have a disruptive impact on food prices and on local ecosystems where the plants are grown.
“If you care about the environment, you should care about where we are getting these fuels, whether we use the oil sands or biofuels,” said Brandt. “Our study is agnostic on what mix of oil substitutes emerges, but we do know that if we don’t manage them well, there will be big consequences.”
The study forecasts global oil demand through 2100 under a variety of scenarios for economic growth, population, efficiency gains and fuel substitution. Interested parties can use the study’s model, inputting their own set of assumptions at Oil substitution and the decline in conventional oil.
Steven Gorelick, Stanford professor of environmental Earth systems science, and Matthew Ganser, director of engineering at Carbon Lighthouse, are the study’s other co-authors.
