Pipelines test correctness and sometimes performance, but energy regressions slip through for months. The research shows energy checks in CI are feasible; almost nobody runs them.
The fix you can use today
Measure a fixed scenario's energy in CI on the same runner every time.
Set a threshold and flag builds that exceed it.
Repeat runs to separate a real regression from noise.
GreenCode researchers found that energy checks can run in CI just like speed checks, but few teams do it.
Tools that help
Eco CI: estimates the energy of CI pipeline runs on GitHub Actions and GitLab, per step
Green Metrics Tool: measures the energy of whole software scenarios run in containers, so runs can be repeated and compared
GreenFrame: measures the footprint of a web application's user scenarios and enforces carbon budgets in CI
How GreenCode helps
GreenCode helps tackle this by building the test scenario for you: a load test generated from the system's own endpoints that records energy as well as speed and ranks the hotspots by energy. More on this.
