Economy System and Energy Intensity Classification

In this paper the critical role of the state economy system on the energy intensity is presented. The classification is obtained through a study on 11 countries energy strategies. These countries include USA, UK, Japan, India, S. Africa, S. Korea, Malaysia, Australia, China, Russia, Saudi Arabia, and as well Iran. Many different economical, social, political, and other parameters that affect state energy intensity were examined. The most relevant parameters for the classification of all these countries are the macro-economic parameters such as the economy freedom index, gross national income and gross domestic product. The countries clearly are divided in three groups, developed countries with free economy systems and low energy intensity, developing countries with semi-free economy and intermediate energy intensity, and countries with almost governmental economy (low economy freedom index) and high energy intensity. Details of different strategies of these three groups are also classified and presented.
