Choose power for the demand you have.
Skie Field Manual · Evidence reviewed 9 November 2026. Read the linked reference for formulas, sources and version limits; current account settings remain the final check.

This guide covers:
- Calculate solar and fusion output on the same baseline.
- Understand why Energy Technology improves every reactor.
- Plan a transition without losing mine production.

Compare three different power sources

Solar Plants provide durable power without fuel. Satellites save fields but are vulnerable and temperature-dependent. Fusion offers dense, durable output at a Deuterium operating cost. The best mix depends on the demand, resources and infrastructure you already have.

Understand the scaling

Fusion output depends on reactor level and account-wide Energy Technology. Economy speed scales baseline fuel consumption, not energy output. Energy Technology does not raise Solar Plant or satellite output. Exact formulas and display-rounding assumptions are in the reference.

Read the worked comparison

The full-output comparison separates generated energy, fields and hourly fuel at ×1 and ×8 economy. It establishes output and field efficiency, not equal-cost superiority. Use the seven-row worked table before pricing an actual transition.

Why the same reactor becomes better

A shared Energy Technology upgrade can benefit several reactors, while a reactor upgrade helps one planet. At a common demand, compare total support costs and the resources retained after fuel. Spare power alone is not the financial benefit.

Switch in a controlled sequence

Keep existing production powered until replacement supply works. Compare net Deuterium and the next mine or crawler demand, retain recovery capacity, and verify any partial reactor setting in the resource screen. The reference preserves a transition checklist.

The decision rule

Prefer a system that meets useful demand with affordable construction, sustainable fuel and acceptable exposure. Existing solar, fusion and a modest satellite reserve can coexist. Do not demolish working infrastructure solely because a fresh-build calculation favors another option.

Quick checks:
- My comparison uses the same bonuses and workload.
- Economy speed scales fuel, not baseline energy.
- I included research and fuel costs.
- The gain was checked across all reactors.
- The transition keeps mines powered.
