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 Most of us believe (or want to believe) that the second carbon era, the Age of Oil, will soon be superseded by the Age of Renewables, just as oil had long since superseded the Age of Coal.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 trillionbetween 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.
