Biomass boilers use a process of gasification and combustion to extract the energy from biological material to generate heat (by heating water) or electricity (by boiling water to produce steam and power turbines). Biomass boilers have a limited environmental impact because the carbon involved is already part of the natural carbon cycle. In contrast, fossil fuels permanently add carbon to the environment when they are burnt.
