About Firewood

  • 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 is the most easily available form of fuel, yet firewood is becoming scarcer.
  • One by-product of wood burning is wood ash, which in moderate amounts is a fertilizer, contributing minerals, but is strongly alkaline.
  • Wood is a renewable resource, offering a sustainable, dependable supply.
  • Wood burning does not release more carbon dioxide than its biodegradation. Wood burning can therefore be called “carbon neutral.” CO2 is typically 90% less than when burning fossil fuel.
  • Wood contains minimal amounts of sulfur and heavy metals.
  • Not a threat to acid rain pollution and particulate emissions are controllable.
  • Burning wood produces smoke. The amount of smoke varies depending mainly on two factors: how dry the wood is and how efficient the burning is.
  • Modern stoves are designed to produce little smoke if used properly. Some stoves have a catalytic "after-burner", a ceramic honeycomb in which smoke and other particles are consumed.
  • Wood is usually significantly less expensive than competing fossil fuels.
  • Wood is bulky, storage can be a problem.
