Fusion Reactors vs Geothermal Taps
Comparing the Fusion Reactors (Tier 2) and Geothermal Taps (Tier 2), both energy technologies in Starforge MMO. Use this to decide which to queue first when your research lab can only run one project at a time.
Research Comparison
| Attribute | Fusion Reactors | Geothermal Taps |
|---|---|---|
| Tier | T2 | T2 |
| Research time | 6▼ | 7 |
| metal cost | 8,000▼ | 9,000 |
| crystal cost | 4,000▼ | 5,000 |
| Effect | +100% energy output | +25% energy output terrestrial |
▼ marks the lower resource / time cost. Cheaper isn't always better — weigh it against the effect each tech unlocks.
Fusion Reactors
Fusion reactors double energy output.
Unlocks buildings: fusion reactor
Requires: energy 1
Geothermal Taps
Drill deep into planetary cores to tap geothermal vents. +25% energy on terrestrial worlds.
Unlocks buildings: geothermal plant
Requires: energy 1
Which Should You Research First?
Both sit at the same tier. The Fusion Reactors is the cheaper project, so it's the safer early pick if your economy is tight; otherwise prioritise whichever effect supports your current strategy.
