Carbon-aware scheduling · updated 2026-06-06 14:01 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 64% of Italy's electricity demand around 14:15 UTC.
- Renewable output peaks around 14:00 UTC at roughly 67% of demand — the greenest time to use electricity today.
- The renewable share dips to about 3% around 19:30 UTC, when grid electricity is at its most carbon-intensive.
