Wind turbines generate a variable amount of power directly proportional to the wind speed.

Acquisition

Wind turbines can be constructed once the Electricity research project has been completed. They require Steel 100 Steel, Component 2 Component, 3,300 ticks (55 secs) of work, and a Construction skill of 4.

Summary

Wind turbines generate a variable amount of power base on the current wind speed, which in turn is based on ranges set by the current Weather. It produces a wattage directly proportional to the windspeed. They output 2300W at 100% wind speed, and 3450 W at 150% wind speed, the maximum. Wind direction is not a factor, so orientation of the turbines doesn't matter; they will spin equally well in any direction.

Like all generators, each tile of a wind turbine counts as a power conduit. Turbines directly adjacent to each other will connect (see Fig. 1), and appliances within 6 tiles can connect to any tile of a turbine

Exclusion zone

The wind turbine's exclusion zone (7ˣ18 white rectangle) is visible when the turbine is selected, or when placing the wind turbine blueprint. Any trees, mountains, roofs, and most buildings will reduce the turbine's output by 20% - five obstructed tiles reduce power to 0. The exclusion zone of several turbines may overlap, so long as the turbine building itself isn't in any of the zones.

Low-lying objects like solar generators can be placed without hindering the turbine's operation, and are an efficient use of space. Growing zones (if not set to trees) or artifical flooring can also be used to prevent wild trees from growing.

The following objects block wind turbines, and are not low-lying:

Analysis

Wind turbines are a renewable (i.e, maintenance-free) source of energy, and have the advantage of requiring no research past Electricity. Both wood-fired generators and chemfuel generators will constantly require a source of fuel.

Wind itself is fairly inconsistent in terms of power, but this problem is almost entirely mitigated by installing batteries, which do require some research. With a battery, wind becomes a stable energy source, working day and night. An eclipse will completely shut down a solar generator, but no event can entirely stop wind. Only a small subset of other dangers, like fog or rain weather controllersContent added by the Royalty DLC, can reduce it.

Their other main drawback is the space requirement - a need for a large, open area clear of trees, mountains, buildings, roofs and other tall constructions. This makes turbines harder to protect. You can still build a wall just outside of its zone, but supporting multiple turbines quickly becomes a time and space consuming project.

Watermill generators and geothermal generators offer completely consistent power, but require dedicated research, and can only be built in certain locations.

Tips

  1. Certain weather conditions offer a positive modifier to wind, like Thunderstorm or Snow. If a weather controller of those types is deployed, then it may be in your interest to preserve them.
