1.This figure omits traditional and/or solid biofuels. It only considers transport biofuels. The full list of crops includes more than 200 sources. Here only the most representative ones are shown. 2. Many advanced biofuels can be sourced from almost any type of biomass. Listed here are the most common or those used in specific production processes.
