Wood fuel is wood used as fuel. The burning of wood is currently the largest use of

energy derived from a solid fuel biomass. Wood fuel can be used for cooking and

heating, and occasionally for fueling steam engines and steam turbines that generate

electricity. Wood fuel may be available as firewood (e.g. logs, bolts, and blocks),

charcoal, chips sheets, pellets and sawdust. The particular form used depends upon

factors such as source, quantity, quality and application. Sawmill waste and

of picking up dead wood, or little tools, although as in any industry, specialized tools,

although as in any industry, specialized tools, such as skidders and hydraulic wood

splitters, have evolved to mechanize production. The discovery of how to make fire

for the purpose of burning wood is regarded as one of humanity’s most important

advances.
