Sustainable Software Engineering, Building Carbon-Efficient Applications
summary
Outlines eight principles hosted at principles.green and argues the priority is carbon per useful work, not vague “green” buzzwords; gives concrete measures like carbon intensity in grams CO2 per kWh (global average ~519 gCO2/kWh), cites tools for real‑time data (electricityMap, WattTime), and recommends actions: schedule batch jobs for low‑carbon windows, move workloads to low‑intensity regions, optimize for energy proportionality, and extend hardware lifetime. Claims global energy need is ~18 TW versus huge solar potential, and offers Microsoft/Kubernetes guidance as early practical outputs.
