1. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
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 develo

9. Eficiência agronômica das adubações nitrogenadas de plantio e após o primeiro corte avaliada na primeira soca da cana-de-açúcar / Agronomic efficiency of nitrogen fertilization at planting and after the first harvest, evaluated during the first sugarcane ratoon cultivation
Renewable energy sources will gradually replace non-renewable sources due to economic sustainability reasons and to the rational use of natural resources. Consequently, this study aimed to investigate sugarcane nitrogen fertilization in detail, which may help the country to become a world model in the production and use of renewable biofuels. The current kno
