Abstract
This article seeks to evaluate some plants for electricity generation existing in Brazil, among which wind, thermal, hydroelectric and nuclear power, through the Full Cost Assessment tool. Two studies were prepared, the first deals with the analysis of these plants in view of the technical-economic, environmental and social factors. The second study is the analysis of these plants in view of the cost of energy and energy production in the five Brazilian regions - South, Southeast, Midwest, North and Northeast. The final results show that in the first study the wind farm had the highest valuation, so the best option among the others. However, the second study, wind power was the one that obtained the highest valuation for the Northeast Region, and the thermoelectric and hydroelectric plants had the highest valuation for the Southeast Region.
Highlights
Especially since the industrialization period, human activity is impacting the ecosystem and its environmental resources
The results show that wind energy appears as 1st choice followed by nuclear, hydro and thermal power in the application of Full Cost Assessment (FCA) in the evaluation of these four plants for electric power generation in view of the environmental factors, technicaleconomic and social
The application of FCA in the first study shows that wind energy appears as 1st choice, followed by nuclear energy, hydroelectric and thermal
Summary
Especially since the industrialization period, human activity is impacting the ecosystem and its environmental resources. As stated by Hawken, Lovis and Lovis (2007), the process of production and mass consumption in the world today and factors arising as rapid industrialization, spatial concentration, agricultural modernization, significant population growth and increasing urbanization, climate change, depletion of productive resources, water scarcity, pollution of soil water and air, make up the main points of pressure and human awareness of global environmental issues. The worsening environmental situation demand studies and the development of alternative proposals to overcome the contradictions of the present world scenario, being prudent to search for methods that preserve natural resources, which often requires the need to make decisions from the simplest to the most complex. The development of a model representing reality can help in choosing the most appropriate decisions. Mathematical models use mathematical relationships to describe or represent an object or decision problem, and may, in his creative process, assist in the understanding of the problem, and as a result improve decision analysis
