Power bills behind the chatbot
Always-on AI sits on a growing electricity stack. Treat idle inference and vanity jobs as real load, not vibes.
The trap
A fluent answer arrives in seconds. The plant behind it bills in megawatt-hours. Treating every casual prompt as free energy is a craft failure, not a moral panic.
What the evidence shows
The International Energy Agency (2025) estimated global data-center electricity at about 415 TWh in 2024 and projected roughly a doubling by 2030 in its base case (toward about 945 TWh), with AI-related demand an important driver of growth. The Congressional Research Service (2025) reviewed U.S. estimates placing data centers near 4% of U.S. electricity in 2023 in cited analyses, and noted separate estimates that AI may already account for a non-trivial share of data-center energy.
None of that means your one email draft burns a town. It does mean always-on, high-volume, low-value compute is not ethically or operationally free.
What this means for people
Households and firms share grids with data centers. Efficiency and honesty about when not to run a model are part of clear-eyes use.
Practice (15 minutes)
- List your top five AI uses this week.
- Mark each: necessary, nice, or vanity.
- Cut or batch one vanity pattern (extra regenerations, mega-context dumps for curiosity alone).
- Prefer the smallest tool that meets the job when the risk is low.
Reflection
Which prompt habit is mostly entertainment dressed as work?
Skeptic check
- Global and national aggregates are not your firm’s PUE.
- Outlooks depend on efficiency and demand assumptions (International Energy Agency, 2025).
- CRS synthesizes multiple studies; open the underlying citations before you cite a single percentage in a board deck (Congressional Research Service, 2025).
