The rest of the paper is organized as follows: section 2 explains the data sources and the methodology used based on concentration measures. The subsequent section focuses on the Energy Mix Concentration Index analysis and the results obtained. The article ends with a few concluding remarks.32 p.application/pdfeng© 2019 Elsevier B.V.
