Viabilidade econômica de sistemas fotovoltaicos residenciais de microgeração distribuída de energia solar
(Universidade Federal de São Carlos, 2023-07-27) Ferreira, Leonardo Hirata; Bragagnolo, Cassiano; https://lattes.cnpq.br/3604206454925741; https://orcid.org/0000-0002-9177-3791
This paper discusses the economic viability of a residential photovoltaic system for distributed microgeneration, its importance as a sustainable energy source, and its potential impact on household expenses. The current context of solar energy is presented with a focus on recent developments in distributed generation. Additionally, this paper presents and discusses the solar energy market and prospects, considering the implementation of the Legal Framework for Micro and Minigeneration (LFMM) through Law 14,300/2022. Furthermore, this study encompasses an analysis of the financial attractiveness of installing grid-connected photovoltaic systems, considering various relevant factors such as local solar incidence, equipment, and installation costs, as well as the cost of energy supplied by distribution companies. Widely recognized financial indicators, including Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period, and Levelized Cost of Electricity (LCOE), were used. The findings emphasize the significance of residential photovoltaic systems in reducing household energy expenses and promoting clean and sustainable energy sources.
A identidade dos Institutos Federais de Educação: o velho resiste em morrer e o novo não consegue nascer
(Universidade Federal de São Carlos, 2023-07-27) Rocha, João Antonio; Nosella, Paolo; https://lattes.cnpq.br/7159165045266256; https://lattes.cnpq.br/2615517527546046
The Federal Institutes of Education Science and Technology are part of a process of reordering and reconfiguring professional education, initiated by President Luís Inácio Lula da Silva after the sanction of Decree No. 5,154/2004, replacing that of No. 2,208/1997, previously sanctioned by former President Fernando Henrique Cardoso. This thesis, based on a theoretical-critical analysis of the policy for professional education that permeated the Lula/Dilma governments (2003-2016), has as its main objective to investigate and analyze the process of construction of the identity of the Federal Institutes from the understanding of their political-pedagogical dilemmas. With regard to the theoretical methodological procedure, initially, it was sought to elaborate a study on the trajectory of the network of federal technical schools in Brazil, based on the documents, guidelines and legislation that guided the conception of creation of the Federal Institutes. Then, through a bibliographic review associated with the analysis of documentary sources and legal documents, this research aimed to understand the plot that hides behind the educational policies that historically direct the poorest young people to vocational high school. It was found, therefore, that, in order to better understand the faces of the crisis of the Federal Institutes, it is pertinent to identify the dilemmas that have guided the (in) political-pedagogical decisions of the new institutionality of the Federal Institutes.
