Is it Time to Stop Worrying about Peak Oil?

Is it Time to Stop Worrying about Peak Oil?

Demand for oil will reach its own peak and decline before humans deplete the Earth’s supply of oil, experts say.

“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,” says study co-author Adam Brandt, assistant professor of energy resources engineering at Stanford’s School of Earth Sciences.

China’s electric scooters

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,” says 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.”

Green competition

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,” says 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 most 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,” says Millard-Ball. “That would hasten the onset of a demand-driven peak.”


What about climate?

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,” says 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.

    As I am aware, no energy source matches the real $/btu and btu/kg of conventional oil. I can only see economic activity forced to take a step back as civilisation shifts away from this convenient energy sourse that it had enjoyed for so long. So, if a terminal decline in standard of living is perfectly acceptable then, no, we dont have to worry about peak oil.

    "If prices rise above their currant levals for an extended period, we're likey to see even more efforts to improve efficency and exploit alternatives to conventional oil."

    So this "peak demand" is driven by rising prices. In other words price rationing driven by insufficiant supply and the increased cost of production of unconventional oil. Or you just could say Peak Oil.

    All the alternatives mentioned such as electric cars, green etc rely on fossil fuels to produce. (forge metal, plastics etc) Fact is we are so oil dependent that even a small dip in production and availability will have significant effects on the world economy. Whitewashing it as this article attempts is amusing at best
