Biofuels represent a complex issue in the sustainability discourse as they require the simultaneous consideration of different dimensions and scales of analysis. This situation explains the co-existence of contrasting ‘scientific evidence’ about their performance. This paper presents a novel conceptual framework that integrates four key aspects of the performance of biofuels: (1) the social factors determining the desirability of biofuel use on the demand side – why do we want to produce biofuels?; (2) the internal technical and economic constraints affecting the viability of their mode of production on the supply side – how can we produce biofuels?; (3) the external biophysical constraints limiting the feasibility of their production – what are the material limits imposed by the availability of natural resources?; (4) the level of openness of the biofuel system referring to the imports used to overcome local limits – the level of externalization of the requirement of natural resources and technical production factors reducing energy security. The proposed framework generates a biophysical characterization of the supply function of a biofuel system (which inputs are needed to generate the supply) contextualized against a biophysical characterization of the societal demand (what inputs the society is ready to invest in the energy system in order to obtain the supply).

消除生物燃料的混乱:一个概念框架,用以检查生物燃料的可行性,可行性和可取性

生物燃料在可持续发展方面代表着一个复杂的问题,因为它们需要同时考虑不同维度和规模的分析。这种情况说明了有关其性能的“科学证据”对比并存。本文提出了一个新颖的概念框架,该框架整合了生物燃料性能的四个关键方面:(1)决定需求方使用生物燃料的可取性的社会因素–我们为什么要生产生物燃料?(2)影响供应方生产方式生存能力的内部技术和经济限制-我们如何生产生物燃料?(3)限制其生产可行性的外部生物物理限制因素–自然资源的可获得性施加了哪些物质限制?(4)生物燃料系统的开放程度是指用于克服当地限制的进口–自然资源需求的外在化水平和降低能源安全的技术生产要素。拟议的框架生成了生物燃料系统的供应功能的生物物理特征(需要输入以生成供应),并根据社会需求的生物物理特征(社会准备为能源系统进行投资而准备投入什么)获取供应)。
