| Solar Panel (Basic) | 50W (daytime only) | Iron Ingot (6), Copper Wire (4), Glass (4) | 80% on clear days, 40% cloudy, 10% storm | Primary daytime power. The backbone of early-to-mid game energy. |
| Solar Panel (Advanced) | 120W (daytime only) | Steel Ingot (8), Advanced Circuit (4), Reinforced Glass (6) | 90% clear, 60% cloudy, 25% storm | Upgrade from Basic as soon as Advanced Circuits are available. Nearly double the output. |
| Wind Turbine (Small) | 30W (24h, wind-dependent) | Iron Ingot (10), Copper Wire (6), Wood (8) | Varies by altitude and weather. Higher islands = more wind. | Supplemental night power. Place at the highest point on your island. |
| Wind Turbine (Large) | 80W (24h, wind-dependent) | Steel Ingot (15), Circuit Board (8), Wood (12) | Varies by altitude. Up to 2x Small Turbine output on high islands. | Primary night power for mid-game. A pair of Large Turbines can power a small base overnight. |
| Geothermal Generator | 200W (24h, constant) | Titanium Ingot (20), Quantum Core (2), Diamond Drill (1) | 100% regardless of weather or time | Endgame baseline power. Constant output eliminates the need for batteries — but extremely expensive to build. |
| Fusion Reactor | 500W (24h, constant) | Diamond (20), Quantum Core (5), Exotic Matter (3) | 100% — the ultimate power source | Endgame final upgrade. Powers an entire fully-developed base indefinitely. |
