Wind Turbine

The Wind Turbine is the first constructible power generator in Dyson Sphere Program and one of the simplest ways to produce electricity early on. It generates power continuously without fuel, day or night, which makes it a very reliable starter source and a useful fallback for small, isolated production sites. In the early game it can also serve as part of the basic power distribution network, since its connection range and output radius let it act as a modest transmission point as well as a generator.

Wind Turbines are especially efficient in terms of the resources required per kilowatt produced, outperforming Solar Panels and Ray Receivers in raw construction efficiency. Their output, however, depends entirely on the planet’s wind energy ratio. This ratio is fixed by planet type and is not affected by weather, time, or other factors. At 100% wind energy, a Wind Turbine produces 300 kW; on planets with lower or higher wind ratios, the output scales accordingly, from 0 kW on windless worlds to 480 kW on the strongest wind planets.

A major limitation is spacing: two Wind Turbines cannot be placed too close together, with a minimum distance of about 10.4–11 meters, which is roughly 9 to 10 grid spaces depending on the terrain. This makes large wind farms inefficient if they are laid out casually. The placement restriction can be worked around by planning the layout carefully, since multiple turbines can be placed in one drag action as long as all preview positions remain valid. This is particularly useful for ring-shaped layouts around a planet’s equator or for long lines of turbines placed along coastlines.

Once Steel Smelting is researched, Wind Turbines can be placed on water without Foundations. This is one of their most important uses, because oceans and lakes provide huge buildable surfaces where spacing constraints are easier to manage. On suitable planets, dense offshore wind farms can provide a very large amount of power with remarkably low material cost. Because of this, it is common to use rows of Wind Turbines across water both as a power source and, in long-distance setups, as a practical substitute for power poles that also generate electricity.

• Wind Turbines can be dragged into lines by holding the mouse button while placing.
• Holding Ctrl while dragging allows diagonal batch placement.
• After Steel Smelting is unlocked, they can be built on water without Foundations.
• Their output is determined by the planet’s wind energy ratio.
• They are effective for early bases, remote mining outposts, and other low-demand facilities.
• On windy planets with large oceans, they remain useful well into the late game.

The crafting recipe is also very cheap: each Wind Turbine requires Iron Ingots, Gears, and Magnetic Coils, with a total raw material cost of 11 Iron Ore and 2 Copper Ore per turbine, plus the intermediate materials needed to make the parts. This low cost is what makes large-scale deployment practical, especially when building over water.
