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 from time to time to feed the steam engines and steam turbines that generate electricity. Wood fuel can be used as fuel (eg, logs, bolts, blocks), charcoal, wood chips, leaves, pellets and sawdust. The particular form used depends on factors such as origin, quantity, quality and application. Sawmill waste and construction industry, the derivatives also include various forms of wood waste. Some argue that wood fuel bad for the environment, but this is not the case if you use proper techinques. Carbon dioxide released by burning wood is equal to the carbon as wood rots. You can increase your carbon emissions using gas powered saws and splitters in the production of wood, but wood heat when replacing the production of carbon fuels such as propane, heating oil or electricity in a combustion plant coal, then burning wood has a positive impact on carbon footprint.

Wood may be used inside an oven, a stove or fireplace. The wood can also be burned in an outdoor fire pit, or fire. Wood is the most readily available fuel, without tools for collecting dead wood or small tools, but as in any industry, specialized tools, such as skidders and hydraulic wood splitters are have evolved to mechanize production.

The discovery of how to make fire for the purpose of burning wood is regarded as one of the most important advances of mankind.
