Sustainability is now a core KPI for the CTO. IT hardware and data center cooling account for roughly 2% of global electricity consumption, a number that is rising rapidly with the growth of AI.
Building a "Green" stack involves:
* **Regional Selection:** Choosing cloud regions powered by renewable energy.
* **Cloud Efficiency:** Writing efficient code that requires less compute power—and thus less electricity.
* **Lifecycle Management:** Ensuring hardware is repurposed or recycled responsibly rather than ending up in a landfill.
Profit and Planet are no longer at odds; an efficient, sustainable infrastructure is often the most cost-effective one as well.
