The geography of the joule.
The American data-centre buildout reveals an unresolved question: who controls the right to consume energy?
RESEARCH NOTE / OCTOBER 2026
Energy as a political geography
The US holds 32.0 GW of operational data-centre power capacity, with another 70.6 GW under construction or planned, according to Cushman & Wakefield data analysed by Computer Weekly. That is 102.6 GW if all future projects are completed. Planned GW is not installed consumption. The UK has roughly 1.7 GW in operation and about 4 GW including pipeline.
Connect to Energonomy
An Energonomy investigates replacing opaque financial proxies with accountable energy and material accounts. The chart reveals how capital presently secures rights to energy at particular grid nodes before energy is actually drawn. Connection contracts, transformers, cooling, land, permits and public infrastructure determine where computation can happen.
Accounting in physical units
1 GW continuously drawn for one year represents 8.76 TWh. Hence 32 GW at hypothetical constant full utilization would be 280.32 TWh/year; this is a unit conversion, not a measurement of US data-centre energy consumption. Public accounts must distinguish contracted capacity (GW), actual delivered energy (MWh), hour-by-hour availability, network congestion, reserve priority, emissions, cooling water and material throughput.
The constitutional consequence
Cheaper energy does not automatically decentralize computation. Chips, land, cooling, grid rights and institutions remain scarce. Energonomy should make resource allocation contestable and auditable, protect basic energy access, permit multiple compute operators and preserve privacy. Physical accounting cannot settle legitimacy or moral priorities by itself.
What can be tested?
Track which planned projects become operational; compare available MW with energy delivered; audit public grid costs of private priority rights; quantify distributional effects of energy pricing; test whether abundance disperses computing power or reinforces platform monopolies.
