Firewood is used to heat homes, and is created by chopping logs into firewood by a wood cutter.
The wood cutter produces 4 firewood for every 1 log. If they are uneducated, they will produce fewer firewood per log, and if they have no tools, they will perform slower, and take longer to produce the firewood.
Heating
Wooden houses each burn an average of 30 firewood or coal each year (this amount depends on the exact length of the winter), and stone houses burn an average of 20 firewood each year - 1/3 less.
