Official Fact Check
Steam confirms renewable energy powers islands. This tool compares source vs consumer load using relative plan units — adjust weather assumptions and bed counts before scaling hydroponics in the Island Planner.
All numbers below are relative plan units for sketching layouts — not official in-game values.
⚡ Energy Sources
+28 plan units
Weather (planning slider)
Solar Panel
10 plan units each (relative)
Good output in open areas. Output varies with weather (cloudy days = less).
→ 20 plan units (mixed weather)
Wind Turbine
8 plan units each (relative)
Consistent output, slightly lower than solar. Good for unpredictable weather areas.
→ 8 plan units (mixed weather)
Water Wheel
14 plan units each (relative)
Highest relative output in this tool — placement rules beta est.*.
🔌 Energy Consumers
−0 plan units
Hydroponic Bed
4 plan units each (relative)
Each bed draws continuous power in this model. Multiply by bed count.
Water Pump
6 plan units each (relative)
Pumps water for hydro loops — pairing rules beta est.*.
Aquaponic Tank
5 plan units each (relative)
Aquaponic systems draw moderate energy for pumps and aeration.
Crafting Station
3 plan units each (relative)
Active crafting stations draw energy while in use.
Grow Lighting
2 plan units each (relative)
Supplemental lighting for indoor growing or night crops.

Estimate: surplus in plan units
Rough surplus of 28 plan units could support about 7 more hydro beds in this model (not official game values).
☀️ Solar (planning)
Weather slider models cloudy-day dips — not official output.
🌬️ Wind (planning)
Use as a relative supplement in your layout sketch.
⚙️ Water (planning)
