Local energy autonomy and sustainable rural development. Analysis of the predisposition to participate in renewable energy communities
Article Sidebar
Main Article Content
Abstract
Renewable Energy Communities (CER) has been postulated in academic literature as a potential source of opportunities for sustainable rural development. The new strategic lines of the Spanish government suggest that they could begin to be encouraged in a more forceful way, making it necessary to analyze the conditions of the predisposition to participate/invest in this type of initiative. Based on the information collected through a survey in a small town in Galicia, we analyzed, using quantitative techniques (principal component analysis and multiple regression analysis), the sociodemographic and sociopsychological characteristics that determine the willingness to participate/invest in a rural CER project. The results reveal that gender, income level and a social capital factor related to trust and cooperation are significant. These results allow us to
formulate conclusions and recommendations for researchers, promoters and legislators.
