When it comes to energy and economics in the climate-change era, nothing is what it seems. Most of us believe (or want to believe) that the second carbon era, the Age of Oil, will soon be superseded by the Age of Renewables, just as oil had long since superseded the Age of Coal. President Obama offered exactly this vision in a much-praised June address on climate change. True, fossil fuels will be needed a little bit longer, he indicated, but soon enough they will be overtaken by renewable forms of energy.
Many other experts share this view, assuring us that increased reliance on “clean” natural gas combined with expanded investments in wind and solar power will permit a smooth transition to a green energy future in which humanity will no longer be pouring carbon dioxide and other greenhouse gases into the atmosphere. All this sounds promising indeed. There is only one fly in the ointment: it is not, in fact, the path we are presently headed down. The energy industry is not investing in any significant way in renewables. Instead, it is pouring its historic profits into new fossil-fuel projects, mainly involving the exploitation of what are called “unconventional” oil and gas reserves.
The result is indisputable: humanity is not entering a period that will be dominated by renewables. Instead, it is pioneering the third great carbon era, the Age of Unconventional Oil and Gas.
That we are embarking on a new carbon era is increasingly evident and should unnerve us all. Hydro-fracking—the use of high-pressure water columns to shatter underground shale formations and liberate the oil and natural gas supplies trapped within them—is being undertaken in ever more regions of the United States and in a growing number of foreign countries. In the meantime, the exploitation of carbon-dirty heavy oil and tar sands formations is accelerating in Canada, Venezuela, and elsewhere.
It’s true that ever more wind farms and solar arrays are being built, but here’s the kicker: investment in unconventional fossil-fuel extraction and distribution is now expected to outpace spending on renewables by a ratio of at least three-to-one in the decades ahead.
According to the International Energy Agency (IEA), an inter-governmental research organization based in Paris, cumulative worldwide investment in new fossil-fuel extraction and processing will total an estimated $22.87 trillion between 2012 and 2035, while investment in renewables, hydropower, and nuclear energy will amount to only $7.32 trillion. In these years, investment in oil alone, at an estimated $10.32 trillion, is expected to exceed spending on wind, solar, geothermal, biofuels, hydro, nuclear, and every other form of renewable energy combined.
In addition, as the IEA explains, an ever-increasing share of that staggering investment in fossil fuels will be devoted to unconventional forms of oil and gas: Canadian tar sands, Venezuelan extra-heavy crude, shale oil and gas, Arctic and deep-offshore energy deposits, and other hydrocarbons derived from previously inaccessible reserves of energy. The explanation for this is simple enough. The world’s supply of conventional oil and gas—fuels derived from easily accessible reservoirs and requiring a minimum of processing—is rapidly disappearing. With global demand for fossil fuels expected to rise by 26% between now and 2035, more and more of the world’s energy supply will have to be provided by unconventional fuels.
In such a world, one thing is guaranteed: global carbon emissions will soar far beyond our current worst-case assumptions, meaning intense heat waves will become commonplace and our few remaining wilderness areas will be eviscerated. Planet Earth will be a far—possibly unimaginably—harsher and more blistering place. In that light, it’s worth exploring in greater depth just how we ended up in such a predicament, one carbon age at a time.
The First Carbon Era
The first carbon era began in the late 1800s, with the introduction of coal-powered steam engines and their widespread application to all manner of industrial enterprises. Initially used to power textile mills and industrial plants, coal was also employed in transportation (steam-powered ships and railroads), mining, and the large-scale production of iron. Indeed, what we now call the Industrial Revolution was largely comprised of the widening application of coal and steam power to productive activities. Eventually, coal would also be used to generate electricity, a field in which it remains dominant today.
This was the era in which vast armies of hard-pressed workers built continent-spanning railroads and mammoth textile mills as factory towns proliferated and cities grew. It was the era, above all, of the expansion of the British Empire. For a time, Great Britain was the biggest producer and consumer of coal, the world’s leading manufacturer, its top industrial innovator, and its dominant power—and all of these attributes were inextricably connected. By mastering the technology of coal, a small island off the coast of Europe was able to accumulate vast wealth, develop the world’s most advanced weaponry, and control the global sea-lanes.
The same coal technology that gave Britain such global advantages also brought great misery in its wake. As noted by energy analyst Paul Roberts in The End of Oil, the coal then being consumed in England was of the brown lignite variety, “chock full of sulfur and other impurities.” When burned, “it produced an acrid, choking smoke that stung the eyes and lungs and blackened walls and clothes.” By the end of the nineteenth century, the air in London and other coal-powered cities was so polluted that “trees died, marble facades dissolved, and respiratory ailments became epidemic.”
For Great Britain and other early industrial powers, the substitution of oil and gas for coal was a godsend, allowing improved air quality, the restoration of cities, and a reduction in respiratory ailments. In many parts of the world, of course, the Age of Coal is not over. In China and India, among other places, coal remains the principal source of energy, condemning their cities and populations to a twenty-first-century version of nineteenth-century London and Manchester.
The Second Carbon Era
The Age of Oil got its start in 1859 when commercial production began in western Pennsylvania, but only truly took off after World War II, with the explosive growth of automobile ownership. Before 1940, oil played an important role in illumination and lubrication, among other applications, but remained subordinate to coal; after the war, oil became the world’s principal source of energy. From 10 million barrels per day in 1950, global consumption soared to 77 million in 2000, a half-century bacchanalia of fossil fuel burning.
Driving the global ascendancy of petroleum was its close association with the internal combustion engine (ICE). Due to oil’s superior portability and energy intensity (that is, the amount of energy it releases per unit of volume), it makes the ideal fuel for mobile, versatile ICEs. Just as coal rose to prominence by fueling steam engines, so oil came to prominence by fueling the world’s growing fleets of cars, trucks, planes, trains, and ships. Today, petroleum supplies about 97% of all energy used in transportation worldwide.
Oil’s prominence was also assured by its growing utilization in agriculture and warfare. In a relatively short period of time, oil-powered tractors and other agricultural machines replaced animals as the primary source of power on farms around the world. A similar transition occurred on the modern battlefield, with oil-powered tanks and planes replacing the cavalry as the main source of offensive power.
These were the years of mass automobile ownership, continent-spanning highways, endless suburbs, giant malls, cheap flights, mechanized agriculture, artificial fibers, and—above all else—the global expansion of American power. Because the United States possessed mammoth reserves of oil, was the first to master the technology of oil extraction and refining, and the most successful at utilizing petroleum in transportation, manufacturing, agriculture, and war, it emerged as the richest and most powerful country of the twenty-first century, a saga told with great relish by energy historian Daniel Yergin in The Prize. Thanks to the technology of oil, the US was able to accumulate staggering levels of wealth, deploy armies and military bases to every continent, and control the global air and sea-lanes—extending its power to every corner of the planet.
