RESUMO
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly developing and are becoming economically viable alternatives. The objective of this study was to evaluate the economic viability of installing solar and wind power generation systems in the NOVVALIGHT electrical components factory located in Campo Largo, Paraná, Brazil. The most viable model was the combination of solar and wind energy, which would generate approximately 260 MWh of energy per year. Using financing provided by the Brazilian Bank for Economic and Social Development (BNDES), this proposal has an eight-year payback period, net present value of BRL 149,097.42, and internal rate of return of 18%, demonstrating its economic viability.

ABSTRACT Sustainability and economics are current issues in the generation of electricity. The energy matrix is diversified and some forms have stood out, such as wind. Some tools have been developed to improve project efficiency, one of which is Life Cycle Assessment (LCA). This presents solidity when assisting projects financially and environmentally, evaluating materials and processes. The present study aimed to analyze the application of LCA in a wind power plant. After searching the main databases and using filters, the analysis was developed from the information of an article that described the application of the LCA to a wind power plant using computational simulation, providing an overview of the production and potential environmental impacts for the process manufacturing, parts maintenance, disposal and recycling at end of lifespan. The phases, steps and the threshold diagram of the LCA system were observed. The results showed a high rate of reuse/recycling of some materials and significant reductions in emissions, financial costs and abatement of environmental payback if the materials were recycled at the end of lifespan. Recycling has shown positive environmental aspects and a significant cost reduction, allowing the expansion of markets and optimization of wind projects.
