Energy Devices Documentation
The energy system in Last State allows players to harness renewable and non-renewable power sources to operate electrical devices.
Energy System Fundamentals
How It Works
| Metric | Description |
|---|---|
| Production (W) | Total watts generated by all power sources |
| Consumption (W) | Total watts consumed by all active devices |
| Storage (Wh) | Battery capacity measured in Watt-hours |
Time of Day Effects
| Device | Day Production | Night Production |
|---|---|---|
| Solar Panel | 15W per panel | 0W |
| Wind Turbine | 3W (constant) | 3W (constant) |
| Waterwheel | 10W (constant) | 10W (constant) |
| Generator | 25W (constant) | 25W (constant) |

Consumer Devices
Basic Devices
- Light Bulb (2W): Provides illumination.
- Headlamp (5W charging): Portable light source. Charges when in inventory and grid involves.
- Refrigerator (10W): Prevents food decay.
- Electric Heater (20W): Provides warmth bonus to the tile.
Agricultural Devices
- Grow Lights (10W): Doubles crop growth speed on same tile.
- Sprinklers (5W): Auto-waters crops on same tile every hour.
Grid Management
Access the power management interface via Menu → SYSTEMS → Power.
- Toggle Grid: Turn entire system ON/OFF.
- Battery Status: Green (>20%) / Red (≤20%).
