Carbon-aware scheduling · updated 2026-10-16 21:23 UTC
The AWS eu-south-1 region runs in Milan, Italy, on the Italy electricity grid. educk forecasts when that grid is greenest — using day-ahead wind & solar and demand data from ENTSO-E — so you can schedule carbon-aware workloads (batch jobs, CI, model training, backups, data pipelines) for the cleanest hours.
- Wind and solar are forecast to cover about 7% of Italy's electricity demand around 21:30 UTC.
- Renewable output peaks around 11:45 UTC at roughly 55% of demand — the greenest time to use electricity today.
- The renewable share dips to about 1% around 18:00 UTC, when grid electricity is at its most carbon-intensive.
