Wood is the fibrous tissue found in many trees. It is used as a fuel and as a (organic) construction material
Yield
Yield can vary greatly depending on the tree species used. As a rule of thumb, one acre of forest, properly managed, can yield one cord of firewood per year indefinitly.
Use
Wood can be used as is for heat, cooking, ... Because of the scarcity of wood in many places, other biomass can be used as feedstock, but may have to be densified first. For this task pelletizers are commercially available.
It can also be converted to hydrogen, charcoal, wood gas or ethanol. This allows more efficient use in vehicles as the energy density is then increased.
