Unshifted compute load: Data centres can't shift work to cheaper, cleaner hours
Training runs, batch inference and analytics are scheduled around deadlines and cluster availability, almost never around what electricity costs or emits at that hour. Much of this work is genuinely movable, a few hours either way or a different region entirely, but the information needed to move it lives in a different system from the scheduler, and in most organisations nothing joins them. So flexible load behaves like inflexible load.

Why now
The IEA's April 2025 Energy and AI report puts data centre electricity use at around 415 TWh in 2024, about 1.5% of global consumption, and projects roughly a doubling by 2030 with accelerated servers accounting for almost half the increase: a load growing fast and, unusually for industrial demand, substantially time- and place-shiftable.
Why it matters
A large and rapidly growing load is being treated as though it had no flexibility, when a meaningful share of it does. Making compute schedulable against grid signals is a software problem sitting between two industries that do not yet share a vocabulary.

Problem Radar listens to public reporting, from institutions, research and the press, for problems worth solving, and frames each one to the same standard; Ainna's innovation team chooses and edits every problem before it goes on the Index. Every problem says where it came from, so the framing can be checked. Nothing on the Index comes from a user, and what you bring to Ainna is never published. How Problem Radar works.
The first mass-market electric cars are reaching the end of their first ownership with batteries that have years of useful service left. Battery-health reports exist, but no grade is yet trusted by buyers, insurers and second-life users alike, so buyers discount heavily to cover what they cannot see, insurers guess, and packs that would work well in a home or on a grid for another decade are recycled early or not moved at all.

The constraint on the energy transition moved from manufacturing to administration, and no tooling followed it. Projects sit in interconnection queues longer than they took to design, studies are redone by hand each time the queue ahead reshuffles, and developers cannot see where they stand or what would move them. Most of the capacity that enters the queue is eventually withdrawn, often after years of waiting.
Recycling a device profitably depends on knowing what it contains before you open it, and that information was never attached to it. So the pile is handled as undifferentiated waste: shredded for the few metals that survive the process, or stored, or exported. The materials the world is anxious about securing are sitting in it, and a large part of the reason they are not recovered is identification rather than chemistry.
