Bank of England Governor Andrew Bailey warned Friday that artificial intelligence may need to be rationed. The constraint isn't the technology. It's the power grid.
Bailey said energy supply cannot keep pace with what AI is capable of demanding. That creates a hard choice: which sectors get the electricity, and which don't. He framed this as a moment requiring "very big social choices" for both companies and governments, treating energy scarcity not as an engineering problem with a pending fix, but as a resource-allocation question with real losers.
The source of the warning matters as much as the warning itself. Bailey isn't a tech critic or an energy researcher - he's a central bank governor. When that kind of official starts using the word "rationing," it signals that AI's power trajectory may be structurally unsustainable, not just inefficient. Efficiency pledges and renewable energy commitments are a different conversation.
The AI industry has treated its energy appetite as infrastructure to be built out. Bailey is suggesting it may be a budget to be managed.
