TL;DR: In this article, the authors evaluate energy supply security in all the EU countries and demonstrate the interrelations between dependence and diversity and the role of renewables on dependence, and argue that renewable energy has had a positive contribution to almost all EU28 country's diversity.

TL;DR: In this paper, the authors used Shannon-Wiener index (SWI) and Herfindahl-Hirschman index (HHI) with EIA fuel mix data to estimate energy supply diversity and concentration for 44 islands in order to provide an island specific benchmark approach for energy supply security.

TL;DR: In this article, the authors find that although there is a convergence in emissions intensity in machinery manufacturing and paper and pulp industries, there are significant variations in all other industrial sectors, and demonstrate that the expected higher emissions are driven by both a higher carbon fuel mix intensity in the recipient countries and higher energy intensity in their industrial activities.

TL;DR: In this article, Ireland, Portugal, Spain, Italy and Greece have shown that they have continuously improved their energy supply diversity during the financial crisis and increased the role of renewable energy sources.

TL;DR: In this article, the estimation of fuel mix diversity and energy import dependence with established metrics Shannon-Wiener index (SWI), Herfindahl-Hirschman index (HHI) and Energy Import Dependence are presented against carbon intensity to highlight two angles of sustainable energy supply.
