Energy generators: solar, wind, hydro and biofuel
On this page
The Small Solar Panel stores up to 5 energy; Small Wind Turbine and Small Hydro Station store up to 10. Weather affects the latter generators. Your battery’s carrying capacity is a separate restriction from energy waiting in a station.
Generator choices
| Generator | Condition or function | Recipe gate |
|---|---|---|
| Small Solar Panel | Slow energy production, storage 5 | Project Station Lv.1 |
| Small Wind Turbine | Faster on windy days, storage 10 | Build Turbine World Project, Project Lv.2 |
| Small Hydro Station | Faster on rainy days, storage 10 | Masters of Disguise research, Project Lv.2 |
| Small Biofuel Station | Uses algae biomass for an instant refill | Still Standing research, Project Lv.2 |
These conditions do not supply a fixed energy-per-minute comparison. A weather-dependent station’s name alone is insufficient to predict how much charge you will collect during a particular session.
Construction materials
The solar panel uses 5 Metal Scraps, 5 Scrap Wire and 5 Glass Cullets, for 5 crafting energy. Wind and hydro each use 2 Aluminium Bar, 2 Hard Lumber and 2 Plastic Sheet, also for 5 energy. Biofuel instead uses 2 Aluminium Bar, 10 Glass Cullets and 2 Plastic Sheet.
The crafting planner multiplies direct ingredients for several stations. Placement permissions still apply, so check your energy-station allowance before preparing several new builds.
A full generator is not a larger battery
An action with a 15-energy payment needs enough carrying capacity to make that payment. Visiting a station that stores 10 does not turn a 5-capacity battery into a 15-capacity one. Use battery upgrades to resolve capacity, and the station’s conditions to plan refills between actions.
