One skyline, three timelines. Fast-forward from 2026 to 2060, run a full day, and spend your political capital wisely — every choice you make shows up in the air the city breathes.
10:00 AM · 2026 — Morning shift. Solar waking, the old grid still carrying half the load.
Today's baseline: cheap solar exists, but the grid still leans on fossil backup.
Smog index (lower is better). Changes with the era, your policies and building upgrades.
Solar is humming — batteries topping up.
Tap a building in the skyline to see how its sustainable tech evolves — from clunky pilots in 2026 to city-scale systems in 2060.
Under the hood
Smart lighting & adaptive streets
When the sun sets, the city does not flood itself with light. Windows glow only where people actually are, lamps dim to traffic levels, and by 2060 adaptive lighting has quietly cut the night-time power bill by 40 percent. Watch the skyline flicker awake — and then dim back.
Sunshine by day, batteries by night
The energy mix readout is a live simulation. Solar dominates at noon, wind picks up after dark, and storage bridges the gap — unless you are stuck in 2026, when fossil backup still covers the evening peak. Every era and policy you choose rewrites the bars in real time.
A smog gauge that keeps score
The smog index starts from the era you pick, then responds to you: adopting clean policies lowers it, funding building upgrades shaves a little more. Let it climb past 60 and a haze settles over the skyline — proof that the future is not something we wait for, but something we choose.
