Liddle, Brantley (2010) Revisiting World Energy Intensity Convergence For Regional Differences. Applied Energy, 87 (10). pp. 3218-3225. ISSN 0306-2619

Abstract

World convergence in energy intensity is revisited using two new large data sets: a 111-country sample spanning 1971–2006, and a 134-country sample spanning 1990–2006. Both data sets confirm continued convergence. However, the larger data set, which adds the former Soviet Union republics and additional Balkan countries, indicates greater convergence over its more recent time-frame. Further investigation of geographical differences reveals that the OECD and Eurasian countries have shown considerable, continued convergence, while the Sub-Saharan African countries have converged amongst themselves, but at a slower rate than the OECD and Eurasian countries; by contrast, Latin American and Caribbean and Middle East and North African countries have exhibited no convergence to divergence in energy intensity.
