Laying the Foundation on OSS Environmental Sustainability
summary
CNCF TAG builds a repeatable baseline to measure open source software energy use, adopting the Green Software Foundation SCI spec and running deployments + load tests from a repo into a bare-metal test harness that uses Kepler (and Scaphandre-style) meters to record power. Findings: functional unit R is the hardest value to nail, one project’s custom policies tripled energy use, idle vs loaded profiles differ, and per-release SCI KPIs are produced and pushed to an observability stack so projects can compare and start targeted optimizations.
