Thermodynamics’ Hidden Challenge to Sustainability

Maximum Entropy Production & Sustainability: Why the Drive to Maximize Energy Flow Explains Degrowth’s Struggle

In his 2025 book Energy, the flip side of money, Pierre Noizat delivers a provocative insight: the laws of thermodynamics don’t just govern heat engines—they shape human societies, economies, and our quest for sustainability.

At the heart of his argument is what he calls the “third principle of thermodynamics” (distinct from the classical third law about absolute zero). Better known in scientific literature as the Maximum Entropy Production Principle (MEPP), it states that dissipative structures—open systems far from equilibrium, like living organisms, ecosystems, hurricanes, or civilizations—self-organize to maximize the rate of energy throughput and entropy production under given constraints.

From bacteria optimizing nutrient gradients to economies scaling GDP, systems evolve toward configurations that dissipate available energy gradients as rapidly and effectively as possible. This isn’t malice; it’s physics at work.

Why This Matters for Sustainability

Traditional sustainability frameworks, like the Framework for Strategic Sustainable Development (FSSD/The Natural Step), rest on the first and second laws plus matter conservation: avoid systematic accumulation of substances from the Earth’s crust, synthetic chemicals, ecosystem degradation, and barriers to meeting human needs.

But MEPP adds a deeper layer: living and social systems aren’t passive. They actively seek to capture and dissipate more energy. This drive explains the relentless push for extraction, consumption, and complexity—even when it breaches planetary boundaries.

Noizat elegantly bridges physics and psychology by noting that humans directly feel entropy: we experience high entropy as anxiety or chaos when information is scarce or security is uncertain, while trustworthy knowledge and stable systems lower our internal entropy, fostering clarity and well-being. He connects this insight to money itself — a claim on future energy flows — and to Bitcoin, which converts real-world energy into verifiable, low-entropy information. This human-scale perception, he argues, is why sound money and energy-backed protocols like Bitcoin can meaningfully reduce societal disorder and help align economic self-organization with long-term sustainability.

It also sheds light on why pure degrowth strategies often falter politically and culturally. Contraction fights a fundamental gradient: systems “want” to maximize power and entropy export. Blind restraint feels like swimming upstream against biology, evolution, and economics.

Is Collapse Inevitable?

Not necessarily. Earth is an open system bathed in low-entropy solar radiation (~1.7 × 10¹⁷ W). Life has maximized capture for billions of years without tipping into total chaos: it reached dynamic steady states (climax ecosystems) where throughput aligns with the incoming budget.

We can do the same. The key is redirection, not denial:

• Shift dissipation from fossil/mined gradients to solar/biomass cycles.
• Design circular economies powered by abundant clean energy (near-closed material loops are feasible with enough input work).
• Use human agency—information, incentives, institutions—to steer self-organization toward longevity, efficiency, and well-being over raw throughput.

Social factors like trust, knowledge-sharing, win-win partnerships, and respect for nature reduce wasteful entropy production. But they’re amplifiers for structural change: carbon pricing, regenerative finance, proof-of-energy mechanisms, and metrics beyond GDP.

Physics isn’t fatalistic. The same laws driving maximization also enable balance via the Sun’s subsidy. We choose which gradients to exploit.

Final Thoughts

Noizat’s lens is sobering: sustainability isn’t just ethics or policy—it’s a thermodynamic engineering problem. Ignoring MEPP dooms us to repeated overshoot. Embracing it lets us harness the drive for abundance within limits.

If we get incentives and technology right, humanity can build a high-civilization, solar-powered steady state. Ignore it, and the dissipative urge accelerates the crises we already feel.

What do you think—can we redirect this fundamental principle, or is endless maximization our destiny? I’d love to hear your take in the comments.
