Inequality of renewable energy generation across OECD countries: A note

This study recommends the use of Theil's second measure to investigate international renewable energy generation disparities. This index permits disparities to be broken down within and between groups of countries in a reliable style. An analysis of OECD countries for 1980–2011 shows some basic points: first, drop in renewable energy generation disparities is attributable both to within-group and between-group inequality components; second, between-group inequalities are presently the key contributor to the inequality; and, further investigation on within-group inequalities divulges the significant explanatory role played by North American, European, and Asian and Oceanian countries.
