Matriz energética e desenvolvimento sustentável: uma análise do inter-relacionamento dos países do G7 e Brasil

Abstract

The generation and consumption of energy is a crucial factor for all aspects of life, but it has been marked by a constant increase in demand due to population growth and technological advances. The generation by some energy sources presents disadvantages mainly in relation to the negative impacts on environmental pollution, causing large climatic variations experienced in recent years that are a consequence of greenhouse gas emissions, among which is the emission of CO2. This study aimed to analyze the similarities between the G7 countries and Brazil in relation to the variables of energy generation and demand, economic performance, population development and CO2 emissions in the period from 2012 to 2021. To this end, the cluster analysis technique was used to analyze the relationship between the countries studied and the variables with the identification of similarities between them. At the end of the study it was concluded that, among the G7 countries, Brazil has a greater relationship with Canada regarding the variable of annual intensity of CO2 equivalent emissions, and in the other categories no relationships were established.
