Deep dives
The Thermodynamic Trap of Humanity
Humanity is trapped in a thermodynamic trap that poses a lethal risk, with critical implications estimated around the year 2030. This trap reflects the inefficiency of our global energy supply and use systems, which historically have operated at a low efficiency of about 12%. The reliance on these systems leads to significant resource depletion, as the relationship between energy cost and output becomes precarious. This situation foreshadows a reality where the energy return becomes unsustainable, potentially culminating in a catastrophic collapse soon.
Decarbonization as a Misguided Focus
The emphasis on decarbonizing through renewable energy sources is counterproductive, as it addresses only the symptoms rather than the fundamental thermodynamic issues. Investments in renewables drain energy from existing systems, exacerbating their decline rather than facilitating a transition. This piecemeal approach fails to replace fossil fuels adequately and creates a layer of complexity without resolving the core inefficiencies. Thus, society continues to overlook the essential thermodynamic realities that govern energy production and consumption.
The Incompatibility of Economics and Thermodynamics
Economics has been identified as fundamentally incompatible with thermodynamics, complicating our understanding of energy systems. This incompatibility arises from the monetary emphasis on maximizing profit without recognizing that energy itself is not a commodity, but a gradient. Historical attempts to integrate economic theory with thermodynamics have often fallen short, resulting in decision-making that neglects critical physical principles. Consequently, the reliance on economic growth perpetuates inefficient energy use and contributes to the ongoing crises.
Life on Earth as a Model for Energy Systems
Life operates as a highly efficient system that effectively recycles energy and minimizes entropy, suggesting that humanity can adapt similar principles in our energy usage. By mimicking the natural processes of life, which cascade energy through complex systems, we can develop decentralized, efficient energy solutions. Emerging technologies aim to utilize abundant solar energy while harnessing low-grade heat from our environment, fundamentally changing how energy is generated and consumed. Such innovations not only promise increased efficiency but also promote sustainable practices that align with the laws of thermodynamics.
Towards a Sustainable Future
A pathway exists to overcome the current thermodynamic traps by transitioning towards systems that mimic natural processes, while minimizing reliance on traditional economic frameworks. This involves creating localized energy solutions that harness solar power and ambient heat, allowing communities to generate energy efficiently at the point of use. By shifting away from large-scale, centralized energy sources, cities can evolve into more sustainable entities, less vulnerable to disruptions. Embracing thermodynamic principles and innovative technologies will be essential to fostering a resilient and sustainable future for humanity.
What happens when economics takes precedence over thermodynamics?
Eventually, the system collapses—because being incompatible with thermodynamics is impossible. That’s the stark message of this week’s guest, Louis Arnoux, a scientist, engineer and managing director of Fourth Transition, who has been working on this problem for decades. Louis and his team’s research point to our energy systems collapsing by 2030 because we’re having to spend more energy than ever before to extract fuel. Soon, the energy cost of extraction will equal the energy benefit. Such an equilibrium is, in his words, a dead state.
In the episode, Louis gives a phenomenal overview of the three thermodynamic traps human civilisation is caught in, including how decarbonising to renewables is exacerbating the thermodynamic problem. He explains how our current energy systems work antithetically to the sun and the planet, including the waste problem, before highlighting the role of economics in the creation of an impossible system. He then explains what a possible energy system could look like with the technology we have available, and how we can engineer that system to mimic the efficiency and productivity of life on the planet.
