The AWS eu-north-1 region runs in
Stockholm, Sweden, on the Sweden 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 21% of Sweden's electricity demand around 15:15 UTC.
- Renewable output peaks around 21:45 UTC at roughly 40% of demand — the greenest time to use electricity today.
