Why AI Has a Power Problem

Robo asks an AI to help plan dinner. The answer appears in seconds – but behind it are chips, cooling, a grid connection and a power supply. Why can a brand-new AI data centre be ready and still wait for power? We follow one question from a phone to a power plant: training vs. inference, why cooling needs electricity too, why generating power and delivering it are two different jobs, why a grid connection can't be downloaded, why more efficient chips can still mean more total electricity, what can ease the bottleneck – and whether this affects your electricity bill.
