Energy intensity

It is the energy per GDP.
It is a measure of the economy of a country's efficiency.
A high value indicates a high price of converting energy into GDP. The country is highly materialised and economic growth is dependent of energy consumption.
The goal of economies today is to have a low energy intensity, which indicates a dematerialization of the economy and that you can produce the same with less.
The following figure shows energy intensity per year and per country. 1995 is considered the baseline to which years are compared to (1995=100).

We can conclude that Portugal is not decoupling energy consumption from economic growth. Compared with EU-25 it has the opposite tendency.

This figure shows how Portugal contributes to energy intensity in EU-25.

This figure displays the trendline of the energy intensity per year. It nothing is done, in 2009 energy intensity could be 10% above the 1995 baseline.

2005 and 2006 data contradict the trendline, but this may have occurred due to a decrease in GDP and not exactly in energy consumption. Consulting IEA data, there was a slightly decrease in energy consumption
