A wood-fired generator is a power source that runs by burning wood as fuel, producing some heat as a byproduct.

Acquisition[edit]

Wood-fired generators can be constructed once the electricity research project has been completed. Each requires 100 Steel, 2 Components, 2,500 ticks (41.67 secs) of work modified by the construction speed of the builder, and a construction skill of 4.

Once constructed, they cannot be re-installed, they can only be deconstructed.

Summary[edit]

The wood-fired generator consumes 22 wood per day and generates a constant 1000W as long as it is switched on and fueled. It can hold up to 75 fuel at a time, for a maximum run time of 3.27 days. Fuel consumption is not dependent on how much power is actually drawn. Fuel has to be delivered to the generator by a hauler colonist. It can be switched off; in the off state it will neither consume fuel nor produce power.

It outputs light in a 6 tile radius, with the nearest 3.442 tiles being above 50% light level and considered lit. Note that the light source is centered at the bottom-left tile of the generator, rather than the "true" center of the generator. It heats at a rate of 6 heat per second^{^{[Exact mechanic unclear]}}.

Analysis[edit]

Wood-fired generators incur considerable labor costs for chopping and hauling wood, but provide an improvement from neolithic technology. They can make a decent source of consistent, earlygame power.

Wood powered appliances[edit]

A variety of buildings are powered directly by wood, such as campfires and torch lamps. It is significantly more efficient to fuel a generator and run the electric equivalents, if all 1000 W of power is used. The generator does not scale with power use, so if power is wasted, then fueled versions may be superior. In addition, electric buildings require more infrastructure, and are vulnerable to solar flares and other interruptions.

Wind turbines[edit]

Wind turbines are also unlocked via researching Electricity. They require no labor to maintain, but do require a large amount of space free of structures and trees. This can make them difficult to defend, and completely unsuitable in certain base layouts. Wind turbine power output is variable, realistically forcing the construction of batteries to smooth out periods of low power production.

If you have both wind and wood-fired generators, there's no reason why you can't use both at the same time. You can use wood when wind power is low, turning off the generator when extra power isn't required.

Chemfuel powered generators[edit]

A chemfuel powered generator is generally more efficient in terms of both wood and work. However, it is difficult to obtain chemfuel in the earlygame.

Each chemfuel generator generates 1,000 W of power. Assuming the colony is running a biofuel refinery to make chemfuel from wood, each consumes 9 wood per day and an extra 257 ticks (4.28 secs) of work. Powering the biofuel refinery takes -170 W of power, but takes only 2,000 ticks (0.8 in-game hours) to produce enough fuel for 3.89 in-game days of fuel, or on average equivalent of a constant load of only 1.46 W.

The extra 257 ticks (4.28 secs) of work is not nothing, but the reduced wood saves at least 390 ticks (6.5 secs) of work in tree cutting work, assuming the most efficient harvest tree and that the tree doesn't have to be planted first. This means that a pawn requires a Plant Work Speed of 152% (Plants skill 13) to make it more work efficient to use the wood fired generator, and this increases to a massive 489% speed if the tree has to be planted as well. This also ignores walking distance; the wood-fired generator often forces colonists to walk further as more trees are harvested.

Also, you can make chemfuel out of raw food; corn or even rice take much less work to cultivate than trees, while taking up less space. Meanwhile, insect meat can be extremely plentiful and used all the same. Finally, boomalopes can create chemfuel from grass, which takes no work to grow.

The only disadvantage of chemfuel generators is that they require chemfuel. Biofuel Refining costs 700 points of research. Boomalopes require you to tame / buy the boomalopes in the first place. Provided you can make chemfuel, the chemfuel generator is strictly better.

+Wood-fired generators incur considerable labor costs for [[Chop_Wood|chopping]] and [[hauling|hauling]] wood, but provide an improvement from neolithic technology. They can make a decent source of consistent, earlygame power.
-For example: The [[Passive_cooler|passive cooler]] and the [[cooler|electric cooler]] have the same cooling power (meaning, they will cool the same space by the same number of degrees -- down to the passive cooler's minimum, anyway). The passive cooler uses 50 wood and cools for 5 days, for a wood consumption of 10 per cooler-day equivalent (CDE). Electric coolers use 200 W when on, meaning the wood-fired generator can power 5 of them, and its wood consumption is 22 per day. This gives a wood consumption per CDE of 4.4, which is more than a doubling of fuel efficiency! This is very noticeable if you are playing the tribal scenario and have need for constant cooling.

-Wind turbines, the other generator type unlocked by the electricity research, require [[battery|batteries]] to provide stable power. As such, they in practice require additional research, which you may not want to wait for. They are also a bigger investment (particularly if you take the need for batteries into account), and require more space and care in their placement.

-Conclusion: If you have good access to wood, wood-fired generators are a natural choice for your first generator or two, since they provide stable power with little investment and no need for additional research. Longer-term, the labor cost of chopping down trees and hauling the wood makes the wood-fired generator unattractive compared to non-fueled generators, and it is made obsolete by chemfuel. Since it can be turned off, it can serve as emergency backup after you have made the transition to more efficient generators.
+If you have both wind and wood-fired generators, there's no reason why you can't use both at the same time. You can use wood when wind power is low, turning off the generator when extra power isn't required.
