A principios de 2026, varias plataformas de orquestación incluyen carbon-aware scheduling como opción por defecto o muy visible. Con meses de datos reales, toca evaluar si la promesa de reducir emisiones sin dañar rendimiento se cumple y en qué escenarios.
Four years ago it was an academic curiosity. Today, scheduling workloads by grid carbon intensity is a built-in option in Kubernetes, in several cloud provider services, and in CI tooling. We look at what genuinely changed and what is still more promise than practice.
Software is not immaterial: every request and database query consumes electricity with a carbon footprint. The Green Software Foundation encodes eight practical principles to reduce that footprint without rewriting systems. The result is a more efficient service, a lower cloud bill, and readiness for ESG regulation.
In 2024 sustainable data centers move beyond PUE: liquid cooling becomes standard in AI GPU racks, carbon-aware workload scheduling is already practical with tools like the Carbon Aware SDK, and waste-heat reuse has real cases in Stockholm and Helsinki. The EU-wide energy efficiency directive already requires honest metrics instead of greenwashing.
Renewable energy is now the cheapest source of electricity in much of the world. Battery storage costs have fallen 89% since 2010, commercial solar panels now exceed 22% efficiency, and onshore wind costs dropped 70% in a decade, according to IRENA and BloombergNEF data.
