Two sides of biogas: Review of ten dichotomous argumentation lines of sustainable energy systems.

Societal debates are often constructed through dichotomies influenced by various factors such as cognitive capabilities of individuals, culturally shaped valuation processes, underlying societal struggles for power and prestige, economic competition, technological changes or lock-ins and operation logic of the media and social media. Debates over emerging technologies of renewable energy provide an illustrative example of this polarisation. Based on national-level studies focusing on the development of the biogas sector in Finland, we identify ten pertinent dichotomies of renewable energy and discuss their implications for the transition towards a more sustainable energy system. The dichotomies include: producer vs. consumer, urban vs. rural, local vs. national, domestic vs. foreign, centralised vs. distributed, food vs. energy, environment vs. economy, traditional vs. innovative, long-term vs. short-term, and private vs. public. These diverse and deeply rooted dichotomies structure societal debate. In some cases they may encourage and guide critical thinking, but they may also hinder the renewing of the current energy behaviour and energy system. Societal capabilities that enable the bridging of different but inherently linked dichotomies are a key precondition of sustainable energy transition. • Dichotomies give shape to the energy debate and create framings highlighting or hiding issues. • Dichotomies and societal polarisations based on multiple materials were analysed. • Ten key dichotomies were identified from the national biogas debate in Finland. • Impressions of small-scale and bottom-up types of technologies have dominated the debate. • As a combined effect of the dichotomies, biogas remains to be understood as an isolated solution.
