Cost and potential analysis of photovoltaic power generation at a Brazilian public university. Clean and renewable energy sources, such as solar energy, have stood out for their potential. So, the aim of this work is to estimate the cost and potential of photovoltaic power generation on São Paulo State University (UNESP) campuses. The statistical technique of cluster analysis associated with the analysis of variance (ANOVA) was used, considering the 24 host cities of these campuses, in order to form groups of campuses with similar characteristics of solar incidence and altitude. Four distinct clusters were formed, and the campus with the smallest built-up area was selected within each cluster to measure the cost of deployment and the potential for energy capture of a system by photovoltaic panels. Six photovoltaic plate models with attributes such as model, dimensions, weight, power, efficiency, cell type, and price were considered for the study. It was observed that the CS6K300MS plate presents a more efficient solar capture performance, does not require a very large number of plates, and the cost is median in relation to the others. Although the calculations presented have been made for the campus with the smallest built-up area within each cluster, similar cost and power generation planning and results can be expected for the other campuses within the same cluster. Finally, it is emphasized that the proposed methodology has the potential to be considered or expanded to similar enterprises so that thorough planning is carried out for the acquisition and installation of this system, and the viability of the enterprise is guaranteed.

O desenvolvimento do setor agropecuário relacionados à produção de animais confinados tem causado impactos ambientais devido ao aumento de dejetos. Desta forma, estratégias para um destino correto dos resíduos gerados nos espaços de confinamento pode contribuir para o desenvolvimento das propriedades rurais. Assim, este trabalho visa a verificar as características da produção de biogás para a geração de energia elétrica a partir de dejetos de suínos, bem como a relação custo benefício deste tipo de energia renovável. Para tanto, este estudo foi baseado em uma revisão bibliográfica e documental feito por meio das bases de dados Scielo, Science Direct e em sites governamentais. Os resultados apontam que o biogás além do seu grande potencial energético, possibilita a redução de custos nas propriedades rurais.
