The United Nations has put numbers to what many in the energy and technology industries had been calculating quietly. By 2030, AI data centres will consume 945 terawatt-hours of electricity annually, a figure that approaches the combined national consumption of Pakistan, Bangladesh, and Nigeria. Their water footprint will equal the basic annual drinking needs of 1.3 billion people.
The most consequential industrial contests of the coming decade won't be visible from satellites. They won't be measured in gigawatts of installed capacity or kilometres of transmission line. They'll be measured in angstroms, in interface densities, in fabrication tolerances that determine whether a material converts ambient energy into electrical output or simply dissipates it as heat.
