⚠️ Eco v0.14 is coming — the next major update reworks upgrade modules, so some of these numbers will change. They reflect the current version. What’s changing →
  • Simpler tiers: the 1–4 tiered upgrades become a single Basic / Advanced / Modern upgrade each.
  • Permanent upgrades: a module placed in a workstation is permanent — no more swapping lower tiers out as you progress.
  • Power transitions: a module can change a station’s power type/draw (e.g. a Modern upgrade moves a sawmill from mechanical to electrical power).
  • Talent-integrated: modules now use the same bonus/talent system — any talent benefit (power, labor cost, recipe unlocks) can come from a module.
  • Cheaper to upgrade: with the multi-tier parts gone, fully upgrading a workstation costs significantly less.

We’ll update this calculator shortly after the update releases.

Windmill

WorldObject

Uses wind to produce mechanical power. Requires clear space for 10 blocks in front of the blades for full power generation. Gains a small output boost when placed at higher elevations.

Notes

The Windmill is a large world object requiring a 7x7x2 footprint, and must have a clear 6-block path for its blades in the direction it faces to generate its rated output of 105 J/s of mechanical power. For optimal performance, it needs unobstructed airspace in front of the blades for 10 meters, and being placed at higher elevations provides a small power bonus. As a tier of power generation that produces no pollution, it serves as a clean but site-dependent early-to-mid-game alternative to combustion engines, and its mechanical output can be used directly or converted to electricity via compatible generators.
