3. How is bioenergy produced? 3.1 How is solid wood used to produce bioenergy other than biofuels? 3.2 How are liquid biofuels produced? 3.2.1 First-generation liquid biofuels; 3.2.2 Second-generation liquid biofuels; The source document for this Digest states: Many processes are available for producing bioenergy, from burning sticks and branches for cooking and heating to gasification of wood chips for transport fuel production. Energy producing systems may be compared in terms of energy efficiency, installation costs, carbon emissions, labour intensiveness or any range of costs and benefits.
