Executive Summary

This essay argues that automation is not just transforming production but reorganizing the geography of carbon. As human labor is replaced by machines, energy shifts from dispersed biological and household systems to centralized industrial grids—a “metabolic regime change.” Robots may consume less total energy per unit than humans, but all of it passes through measurable, controllable infrastructures. The result is a smaller but far more governable energy footprint. Decarbonization, therefore, is not only a technical substitution but a spatial and political realignment: carbon moves from kitchens and cars to power plants and data centers, where it can be metered, priced, and captured—economically and politically.

Yet efficiency alone does not guarantee progress. Between 2015 and 2025, global robot energy demand rose 165% while grid carbon intensity fell just 6%, creating a widening “decarbonization deficit.” The essay shows how this mismatch exposes a Jevons-style paradox—efficiency drives expansion rather than reduction. Case studies like TSMC’s Arizona fab reveal how carbon and water follow similar logics: once resources become measurable, they become tradable and flow toward capital. The core warning is clear—without political oversight, decarbonization can morph into recentralization, replacing fossil dependence with data-driven control.

Between 2015 and 2025, industrial robots tripled in population while more than doubling their collective energy consumption. Every efficiency gain was swallowed by exponential deployment. We automate to save energy but consume more of it. Unless power grids decarbonize faster than factories automate—which they aren't—every robot amplifies carbon rather than reducing it.

But something deeper is happening beyond aggregate numbers: a reorganization of where carbon is produced and who controls it. When robots replace human workers, carbon doesn't vanish. It migrates from kitchens and cars to power plants, from millions of decentralized sources to thousands of centralized nodes. This shift isn't about quantity. It's about geometry. And geometry determines control because it creates what we might call an "accountability surface"—the boundary where energy becomes visible, measurable, and thus governable. What follows is the story of how decarbonization creates new control surfaces, and who captures them.

The Metabolic Regime Change

Energy transition talk focuses on fuel switching: coal to solar, gasoline to batteries. Beneath these substitutions runs something deeper—replacing biological metabolism with industrial metabolism. A human worker embodies distributed energy: eating, heating, commuting, consuming. A robot embodies centralized energy: electrons through a single grid connection, measured to the kilowatt-hour, subject to real-time control.

Human energy consumption is diffuse, private, largely invisible to industrial accounting. You don't meter your employee's breakfast. These costs scatter across millions of households. A robot's energy footprint is industrial from birth to retirement—every joule accountable, every emission traceable to one invoice.
