With the rapid economic growth in most Emerging Market Countries, the energy intensity showed a striking decline. To explore this energy puzzle, we evaluated energy intensity reduction in 30 Emerging Market Countries, which were referred to as E30 in this paper. A combined conceptual analysis...

Improving the aggregate energy efficiency is consequential for China's sustainable development and carbon dioxide reduction, but there lacks a systematic analysis of China's energy intensity long-term changes. China's energy intensity fell sharply by 74.7% with great heterogeneity across regions...
