Renewable energy forecast · updated 2026-07-21 16:03 UTC
educk tracks how much of Denmark'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 87% of Denmark's electricity demand around 17:00 UTC.
- Renewable output peaks around 10:00 UTC at roughly 144% of demand — the greenest time to use electricity today.
- The renewable share dips to about 72% around 19:00 UTC, when grid electricity is at its most carbon-intensive.
- There is forecast surplus renewable generation around 10:00 UTC — an ideal low-carbon window for flexible loads such as EV charging, laundry or heating.
