Energy consumption limit. Every AI product has a consumption limit of X GJ. After that, the server just shuts off.
The limit should be high enough to not discourage research that would make generative AI more energy efficient, but it should be low enough that commercial users would be paying a heavy price for their waste of energy usage.
Additionally, data usage consent for generative AI should be opt-in. Not opt-out.
You can make the limit per-company instead. With big fines if you make thousands of companies to get around the law.
