ABSTRACT
In this chapter we succinctly present the energy situations in eleven different countries, in order to illustrate the contrast between them, as they depend on their respective level of economic development, demographics, natural resource endowments, etc. In this introductory book, these studies only are brief summaries of the problems faced by these countries, especially the larger ones. On the educational level, they can be used as a starting point for further studies or as examples for the analysis of other countries’ situations.
