sdatoken.org has been rebuilt — from a reading site into a playground for Europe's electricity grid.
🎛️ Race to Zero — take a real country's actual 2025 electricity mix and try to decarbonise it. Ten sources on sliders, three gauges that fight each other (CO₂, cost, feasibility) plus a stability meter. No cheap tricks: push wind + solar past what the grid handles and the storage bill climbs; retire all dispatchable power and you get blackout risk; drag Germany's nuclear slider and a banner explains the phase-out law. 34 countries, 4 challenges each.
🌍 Europe Live — 30 grids right now: energy mix, carbon intensity, who's exporting, a bubble map coloured by carbon. Countries without live data are left out, not faked.
🕹️ Plus Griddle (a daily Wordle for grids), Higher or Lower, Battle Cards, Energy Olympics — and Solar Studio, which gives real PVGIS yield and payback for any roof in Europe.
📚 25 short lessons on energy, tokenization and governance are folded in, appearing at the moment a game raises the question.
Built on ENTSO-E, Ember 2025 data, IPCC lifecycle factors and PVGIS. 6 games · 30 live grids · 34 playable countries · 0 simulated numbers. Free, no sign-up.
