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 100 Steel, 2 Components, 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, with an output 2300W at 100% wind speed up to a maximum of 3450W at the maximum 150% windspeed. Wind direction is not a factor, so orientation of the turbines doesn't matter; they will spin equally well in any direction.

Exclusion Zone

The wind turbine's exclusion zone (7ˣ18 white rectangle) is visible when the turbine is selected; and when placing the wind turbine blueprint.It is vital to the wind turbine's function to keep the exclusion zone free from trees, mountains, buildings, roofs, and other tall constructions. The turbine's information window (inspection pane) will list any obstructions in its exclusion zone. Each tile that has an obstruction reduces the turbine's output by 20%. Solar generators or Growing zone (that are not set to grow trees) can be placed in the exclusion zone without blocking the turbine. In fact, this setup is an efficient use of space and prevents wild trees from growing in the obstructing the zone. Another option to prevent trees from growing is to construct some type of flooring there.

The exclusion zone of several turbines may overlap. As long as one turbine itself doesn't end up in the exclusion zone of another, they will work optimally.

Low-lying objects can be placed in the exclusion zone without hindering the turbine's operation. These include (but not limit to) the following:

Wind speed

Analysis

Wind turbines are rather inconsistent for power - they might lose power midway through a work bill. However, this problem is mitigated almost entirely by installing batteries. With batteries, 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 controllers, can reduce it. Wind turbines also have the advantage of requiring no research past Electricity, the only renewable (maintenance-free) energy source available from the start.

Their 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

Colonists can build wind turbines without gaps between them this may save resources on power conduits. See Fig. 1 below if this point isn't clear.
Colonists can construct flooring over terrains with <30% Fertility in order to prevent plants from growing. Non-flammable floors will also help against wildfires.
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.
