Source: Authors’ own calculations based on the IEA (2009a, 2009b). The percentages in the
first column show the weight of intra-group inequality in global inequality, while in the remaining
columns the weight of the different components in intra-group inequality is given.
As to the intra-group inequality component, this varies between 30 and 40%,
being approximately 40% at the end of the period (first column of Table 4). This
component also experiences a huge decrease, which helps to explain the global
decline, and reduces at less than 50% its contribution to inequality.
The most relevant component is again final energy consumption per GDP unit
(Tw). In fact, inequalities in this factor are even greater than in global inequalities
in energy intensity. However, in this case the importance of the differences in
transformation indices is greater than for inter-group inequalities. This
component (Tf) represents up to a 15.2% of intra-group inequality at the end of
