1. Regional inequalities in electricity access versus quality of life in Brazil
Resumo Uma das principais desigualdades do Brasil está relacionada ao acesso e distribuição de energia elétrica. Em média, 99,7% da população tem acesso a algum tipo de energia, variando de 99,1% a 99,9% entre os estados brasileiros. No entanto, 600 mil brasileiros ainda não têm acesso à energia elétrica. Este artigo tem como objetivo relacionar a

4. TECHNICAL AND ECONOMIC FEASIBILITY OF USING A VARIABLE-FREQUENCY DRIVE IN MICRO-IRRIGATION SYSTEMS
ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be r

11. Energy Potential of Animal Waste in the State of Paraná (Brazil)
Abstract Animal biomass is a source of energy commonly discarded without or with low utilization, but its availability draws attention to its reuse [1]. The utilization can be carried out in different ways, varying in terms of generation time and efficiency. The use of biodigestion requires a relatively small area compared to landfills or natural composting,
