How to explain the world's tenacious reliance on fossil fuels, despite all that we know about their role in global warming and those lofty promises made in Paris?
To some degree, it is undoubtedly the product of built-in momentum: our existing urban, industrial, and transportation infrastructure was largely constructed around fossil fuel-powered energy systems, and it will take a long time to replace or reconfigure them for a post-carbon future. Most of our electricity, for example, is provided by coal- and gas-fired power plants that will continue to operate for years to come. Even with the rapid growth of renewables, coal and natural gas are projected to supply 56% of the fuel for the world's electrical power generation in 2040 (a drop of only 5% from today). Likewise, the overwhelming majority of cars and trucks on the road are now fueled by gasoline and diesel. Even if the number of new ones running on electricity were to spike, it would still be many years before oil-powered vehicles lost their commanding position. As history tells us, transitions from one form of energy to another take time.
Then there's the problem -- and what a problem it is! -- of vested interests. Energy is the largest and most lucrative business in the world, and the giant fossil fuel companies have long enjoyed a privileged and highly profitable status. Oil corporations like Chevron and ExxonMobil, along with their state-owned counterparts like Gazprom of Russia and Saudi Aramco, are consistently ranked among the world's most valuable enterprises. These companies -- and the governments they're associated with -- are not inclined to surrender the massive profits they generate year after year for the future wellbeing of the planet.
As a result, it's a guarantee that they will employ any means at their disposal (including well-established, well-funded ties to friendly politicians and political parties) to slow the transition to renewables. In the United States, for example, the politicians of coal-producing states are now at work on plans to block the Obama administration's "clean power" drive, which might indeed lead to a sharp reduction in coal consumption. Similarly, Exxon has recruited friendly Republican officials to impede the efforts of some state attorney generals to investigate that company's past suppression of information on the links between fossil fuel use and climate change. And that's just to scratch the surface of corporate efforts to mislead the public that have included the funding of the Heartland Institute and other climate-change-denying think tanks.
Of course, nowhere is the determination to sustain fossil fuels fiercer than in the "petro-states" that rely on their production for government revenues, provide energy subsidies to their citizens, and sometimes sell their products at below-market rates to encourage their use. According to the International Energy Agency (IEA), in 2014 fossil fuel subsidies of various sorts added up to a staggering $493 billion worldwide -- far more than those for the development of renewable forms of energy. The G-20 group of leading industrial powers agreed in 2009 to phase out such subsidies, but a meeting of G-20 energy ministers in Beijing in June failed to adopt a timeline to complete the phase-out process, suggesting that little progress will be made when the heads of state of those countries meet in Hangzhou, China, this September.
None of this should surprise anyone, given the global economy's institutionalized dependence on fossil fuels and the amounts of money at stake. What it doesn't explain, however, is the projected growth in global fossil fuel consumption. A gradual decline, accelerating over time, would be consistent with a broad-scale but slow transition from carbon-based fuels to renewables. That the opposite seems to be happening, that their use is actually expanding in most parts of the world, suggests that another factor is in play: addiction.
We all know that smoking tobacco, snorting cocaine, or consuming too much alcohol is bad for us, but many of us persist in doing so anyway, finding the resulting thrill, the relief, or the dulling of the pain of everyday life simply too great to resist. In the same way, much of the world now seems to find it easier to fill up the car with the usual tankful of gasoline or flip the switch and receive electricity from coal or natural gas than to begin to shake our addiction to fossil fuels. As in everyday life, so at a global level, the power of addiction seems regularly to trump the obvious desirability of embarking on another, far healthier path.
On a Fossil Fuel Bridge to Nowhere
Without acknowledging any of this, the 2016 EIA report indicates just how widespread and prevalent our fossil-fuel addiction remains. In explaining the rising demand for oil, for example, it notes that "in the transportation sector, liquid fuels [predominantly petroleum] continue to provide most of the energy consumed." Even though "advances in nonliquids-based [electrical] transportation technologies are anticipated," they will not prove sufficient "to offset the rising demand for transportation services worldwide," and so the demand for gasoline and diesel will continue to grow.
Most of the increase in demand for petroleum-based fuels is expected to occur in the developing world, where hundreds of millions of people are entering the middle class, buying their first gas-powered cars, and about to be hooked on an energy way of life that should be, but isn't, dying. Oil use is expected to grow in China by 57% between 2012 and 2040, and at a faster rate (131%!) in India. Even in the United States, however, a growing preference for sport utility vehicles and pickup trucks continues to mean higher petroleum use. In 2016, according to Edmunds.com, a car shopping and research site, nearly 75% of the people who traded in a hybrid or electric car to a dealer replaced it with an all-gas car, typically a larger vehicle like an SUV or a pickup.
The rising demand for coal follows a depressingly similar pattern. Although it remains a major source of the greenhouse gases responsible for climate change, many developing nations, especially in Asia, continue to favor it when adding electricity capacity because of its low cost and familiar technology. Although the demand for coal in China -- long the leading consumer of that fuel -- is slowing, that country is still expected to increase its usage by 12% by 2035. The big story here, however, is India: according to the EIA, its coal consumption will grow by 62% in the years surveyed, eventually making it, not the United States, the world's second largest consumer. Most of that extra coal will go for electricity generation, once again to satisfy an "expanding middle class using more electricity-consuming appliances."
And then there's the mammoth expected increase in the demand for natural gas. According to the latest EIA projections, its consumption will rise faster than any fuel except renewables. Given the small base from which renewables start, however, gas will experience the biggest absolute increase of any fuel, 87 quadrillion BTUs between 2012 and 2040. (In contrast, renewables are expected to grow by 68 quadrillion and oil by 62 quadrillion BTUs during this period.)
At present, natural gas appears to enjoy an enormous advantage in the global energy marketplace. "In the power sector, natural gas is an attractive choice for new generating plants given its moderate capital cost and attractive pricing in many regions as well as the relatively high fuel efficiency and moderate capital cost of gas-fired plants," the EIA notes. It is also said to benefit from its "clean" reputation (compared to coal) in generating electricity. "As more governments begin implementing national or regional plans to reduce carbon dioxide emissions, natural gas may displace consumption of the more carbon-intensive coal and liquid fuels."
Unfortunately, despite that reputation, natural gas remains a carbon-based fossil fuel, and its expanded consumption will result in a significant increase in global greenhouse gas emissions. In fact, the EIA claims that it will generate a larger increase in such emissions over the next quarter-century than either coal or oil -- a disturbing note for those who contend that natural gas provides a "bridge" to a green energy future.
Seeking Treatment
If you were to read through the EIA's latest report as I did, you, too, might end up depressed by humanity's addictive need for its daily fossil fuel hit. While the EIA's analysts add the usual caveats, including the possibility that a more sweeping than expected follow-up climate agreement or strict enforcement of the one adopted last December could alter their projections, they detect no signs of the beginning of a determined move away from the reliance on fossil fuels.
