Despite efficiency gains, global compute power consumption has doubled. Can fusion save AI?

The Watts Behind the Wisdom

We have a problem. The latest foundational models are smarter, faster, and more capable than ever. They are also thirsty. The energy consumption of global AI datacenters has surpassed that of the entire aviation industry.

The Efficiency Paradox

Jevons Paradox is in full effect: as AI becomes more energy-efficient per token, we find exponentially more uses for it, driving total consumption up.

The Fusion Hope

The recent breakthroughs in commercial fusion power (specifically the ignition event at NIF-Commercial) offer a glimmer of hope. Several major tech giants have signed exclusivity deals with fusion startups.

Sustainable AI

In the meantime, "Green AI" is the new buzzword. Developers are optimizing for "inference-per-watt," and new hardware architectures are ditching the general-purpose GPU for highly specialized, low-power ASICs (Application-Specific Integrated Circuits).
