Energy intensity trends in 31 industrial and developing countries 1950-1988

Summary, in English

Trends in energy intensities for 31 countries are evaluated, over the period from 1950 to 1988, using a purchasing power parity-based GDP measure and United Nations energy statistics. With non-commercial energy included, the energy intensities of low income countries are similar to those of high income countries. Energy intensities have decreased for 15 out of the 31 countries studied. The analysis indicates that there is a level of energy intensity, between 0.25 and 0.5 toe per 1000 (1980) international dollars, to which many countries are converging. Energy use per capita increases with higher incomes, but cross-country comparisons can be misleading and inappropriate due to large differences in, for example, economic structure and climate. Electricity appears to be the energy carrier of choice for advanced economies, leading to increased use of electricity relative to other energy carriers. Electricity intensities for eight industrialized countries are evaluated. In four countries, electricity intensities have decreased in recent years. This result suggests that electricity intensities may develop similarly to how energy intensities have developed as economic structure and energy end-use efficiency continue to change.
