Determinants of renewable and sustainable energy technologies acceptance: a comprehensive explanatory model for the biofuel case

The doctoral research aims to understand the acceptance of renewable and sustainable energy technology, specifically biofuel technology, by the general public and expert stakeholders. Study 1 identifies barriers and facilitators for biofuel acceptability through qualitative interviews with 32 EU stakeholders from various institutions and countries. The qualitative content analysis reveals four clusters of variables affecting biofuel acceptability. Study 2 builds an integrated model (i-SETA) for biofuel acceptance, incorporating psychological and contextual factors, tested on 807 laypeople from 8 EU countries. Study 3 validates the i-SETA model with 210 European expert stakeholders from four EU countries. The thesis provides valuable evidence-based concepts to promote biofuel acceptance and adoption.
