# The Finite Legacy of Fossil Fuels: A Reality Check for Our Future
Written on
Chapter 1: The Non-Renewable Inheritance
Fossil fuels, as commonly understood, are not renewable resources. We lack the time—100 million years—and the necessary conditions—trillions of plants—to naturally store solar energy in the form of fossil fuels. These resources represent a singular inheritance from organisms that existed long ago, and in just a few generations, we have squandered this legacy on indulgences like sports cars and excessive consumption. While it was an exhilarating journey, the reality is that we are depleting these resources.
Tom Murphy, whose insights I reference, articulates it well: “The current state of apparent success cannot be taken as a meaningful proof-of-concept, because it was achieved at the expense of finite resources in a shockingly short time: an extravagant party funded by the great one-time inheritance. The aftermath is only beginning to appear.”
Last Call
According to Murphy's analysis, we are nearing the end of our coal reserves (nearly half depleted), 80% of our oil, and 50% of our natural gas. Extracting what remains will be increasingly challenging, akin to a desperate search for a vein in the body. Ultimately, the last remnants of these fuels will likely cost more to extract than they are worth.
While one might argue that there are still unproven reserves, discovering and extracting these resources will be costly. By definition, they are not easily accessible, or we would have already identified them. The concept of peak oil refers not to total depletion, but to the point where it becomes economically unfeasible to extract remaining resources. Therefore, much of what is left will remain in the earth.
What Are Fossil Fuels?
Fossil fuels are essentially the remnants of countless dead plants and animals that have been compressed over millions of years. We can no longer rely on the abundance of life that once existed; we've already wiped out 95% of it. Consequently, we face an unsolvable math problem: the rate of fossil fuel replenishment is insufficient to meet our ambitious energy demands. The few renewable resources we do possess are hardly enough to sustain a university campus, let alone our global aspirations. This is how we squander our inheritance.
When will we run out? Estimates suggest we could exhaust oil and gas within 50 years, and if we revert to steam technology, maybe 100 years. These figures are conservative, as the last reserves are likely to be economically unviable to extract.
Chapter 2: The Illusion of Net-Zero
The idea of achieving Net-Zero by 2050 is almost laughable. We are on track to run out of fossil fuels around the same time. It's akin to declaring, “You can’t fire me! I quit!” The reality is that we must transition to net-zero emissions because fossil fuels themselves are on a path to depletion. By 2050, we may barely have enough resources left to even pretend we’re achieving net-zero goals, and by 2080, access to fossil fuels could become nonexistent. This presents a significant challenge, as our economy is deeply intertwined with fossil fuel consumption.
While it's possible to envision a different economy without fossil fuels, we cannot maintain our current lifestyle. Our dependence on fossil fuels is profound, and the decline will be harsh.
Climate change is just one facet of our broader issues; it is a symptom of unchecked growth rather than the root cause. Reducing CO2 emissions is akin to taking pain relief for a serious illness—it may alleviate some symptoms but does not address the underlying issue, which is unsustainable growth. This unchecked expansion continues to deplete resources like lithium and copper, all requiring fossil fuels for extraction. The continued growth consumes land and impacts other species, pushing the planet towards collapse. Merely switching to electric energy will not resolve these fundamental issues.
The Deep Connection to Fossil Fuels
Our way of life is intricately linked to fossil fuels, and many fail to grasp this connection. The so-called Green Revolution in agriculture, for instance, heavily relies on natural gas for fertilizer production and oil for transportation. We are effectively consuming fossil fuels to produce food.
Murphy discusses EROEI (Energy Return on Energy Invested), highlighting that for every calorie we get from food, we expend ten times that energy in production and transportation. Then we pat ourselves on the back for using reusable bags. This disconnect is alarming; fossil fuels are foundational to our modern existence.
Fossil fuels enable the global trade of goods, from pomegranates to toys, all transported by ships that cannot feasibly switch to batteries or wind. Our modern conveniences are wrapped in plastic, another product of fossil fuels. While we could live differently, few are willing to make the necessary sacrifices, clinging to the belief that growth can continue indefinitely.
In closing, Murphy poignantly states:
“The rapid increase in energy and resource use over the past few centuries has been achieved through the swift depletion of a unique inheritance. This remarkable period has fostered a dangerously distorted perception of what ‘normal’ means on this planet. The present-day spectacle is captivating and exhilarating, but it is also extraordinarily rare. Just as a meteorologist trained during a brief fireworks display may struggle to predict future weather patterns, we are ill-equipped to comprehend what lies ahead after this extraordinary phase…”
Substance Addiction
The finite nature of fossil fuels could be seen as a serious concern. While an unlimited supply would exacerbate climate change, the reality is that our current way of life has been built on the assumption of cheap and accessible fossil fuels. We are, metaphorically, like a trust-fund child lamenting the need to work hard, having relied on a substantial inheritance that is now dwindling.
Murphy warns, “Fossil fuels are a one-time resource—an inheritance—that will not continue to drive our future, and nature does not guarantee a better alternative.” In essence, we were foolish in our reliance on these fuels, and now we face the consequences.
