This founder is teaching chips how to recycle (their energy)

Eshan Raul· 8 septembre 2026

Throughout the history of the computer chip, engineers have treated waste heat as an inevitable cost of a calculation. Hannah Earley, however, thinks it’s a design choice. Earley, 31, is cofounder and chief technology officer of Vaire Computing, a startup building chips that recycle energy usually…

Résumé

Traditional chips waste energy

Conventional computer chips generate heat as a byproduct of their calculations.

This happens because, during computations, chips erase intermediate data they no longer need, releasing energy in the form of heat—a process similar to braking a car at every intersection, which wastes momentum and fuel.

This inefficiency is treated as an unavoidable cost in chip design.

For example, data centers, which power everything from cloud services to AI, consume vast amounts of electricity, much of which is lost as heat.

The global data center energy use reached approximately 240–340 terawatt-hours in 2022, accounting for about 1–1.5% of total global electricity consumption.

This waste highlights the need for more efficient computing methods to reduce energy loss and environmental impact.
