Effect
Energy Technology boosts the output of the Fusion Reactor:
Every level adds +0.01 to the reactor's growth base, compounding significantly at high reactor levels.
Research Unlocks
Energy Technology is a prerequisite for:
| Level | Unlocks |
|---|---|
| 1 | Laser Technology |
| 3 | Fusion Reactor |
| 5 | Plasma Technology |
| 8 | Ion Technology |
| 12 | Terraformer |
Tips
Get to Level 3 Early
Energy Technology 3 unlocks the Fusion Reactor. Even if you're not using one yet, it's required for later tech paths.
Level 12 for Terraformer
Energy Tech 12 is the expensive-but-required gate for the Terraformer. Plan ahead.
