The AWS eu-south-2 region runs in Zaragoza, Spain, on the Spain 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 18% of Spain's electricity demand around 18:00 UTC.
- Renewable output peaks around 12:30 UTC at roughly 86% of demand — the greenest time to use electricity today.
