Evolution and Transformation of Energy in the World

The work consists of a detailed study to explore the energy matrices of eleven countries, including Brazil, over a historical period of ten years. Brazil will be compared with the other countries, where the evolution of energy, per capita consumption in each country, consumption by sector, namely the industrial, residential and transportation sectors, will be studied. The analysis of energy sources, related to the various technologies and transformations, also has its importance, in proportion to the country's development, and will be studied, emphasizing the growth of renewable energies, certainly the future of the energy matrices of several countries. The research also includes energy efficiency and the evolution of energy prices over ten years in the chosen countries. With these analyses of the evolution of both primary energy sources and their prices, using graphs and tables, the aim is to compare Brazil with other countries.
