How Biofuel is Made. The energy that we get from biofuels originally came from the sun. This solar energy was captured through photosynthesis by the plants used as feedstocks (raw materials) for biofuel production, and stored in the plants' cells.Many different plant materials can be used for biofuel: Wood and its byproducts can be converted into liquid biofuels, such as methanol or ethanol, or into woodgas. 2  Wood can also be burned as solid fuel, like the familiar firewood. 3  Chipped waste biomass, such as the tops of trees discarded by logging operations, can be burned in specially designed furnaces.
