Global AI energy consumption grew sixfold between 2020 and 2025, rising from 65 to over 415 TWh. Not all of this energy produces measurable value. What makes the difference is the type of AI adopted and the governance framework behind it. Sustainability is not a declared value: it is a direct effect of governed AI.

KEY TAKEAWAYS

• Ungoverned generative AI consumes energy without producing measurable output in terms of real waste reduction.
• Decisional AI applied to supply chain, procurement, and production reduces operating costs by 15–30%, turning every watt into a better decision.
• Per-query technical efficiency improved twelvefold since 2020, yet total consumption grew anyway; what's needed is consumption governance, not just more efficient chips.
