Why sustainability makes sense for tech
summary
Global internet systems emit ~900 million tonnes CO2 annually and could double by 2025; data centers use 1–2% of world electricity while traffic has tripled since 2015. Practical fixes include raising server inlet temps to 27–30°C inlet temps and using adiabatic wet-wall cooling, cutting cooling energy and water use; a cited operating metric is PUE 1.18 versus a 1.59 average. Other steps: refurbish servers to 10 years, run multi‑cloud via Kubernetes (Cosmos), prefer serverless/object storage and lean coding to cut compute, cost and emissions.
