educk tracks how much of Greece's electricity demand is met by wind and solar generation, using day-ahead forecasts from the ENTSO-E transparency platform. Use it to plan flexible energy use — charging an EV, running appliances or batteries — for when the grid is cleanest.
- Wind and solar are forecast to cover about 18% of Greece's electricity demand around 21:00 UTC.
- Renewable output peaks around 10:30 UTC at roughly 136% of demand — the greenest time to use electricity today.
- The renewable share dips to about 0% around 15:45 UTC, when grid electricity is at its most carbon-intensive.
- There is forecast surplus renewable generation around 10:30 UTC — an ideal low-carbon window for flexible loads such as EV charging, laundry or heating.
