14. Dimensionamento ótimo de sistemas híbridos, com geração fotovoltaica e célula a combustível, para atendimento a comunidades isoladas na Amazônia / Optimal design of a hybrid photovoltaic and fuel cell power generation system, to supply isolated communities in the Brazilian Amazon.
The lack of electricity in isolated communities in the Brazilian Amazon has become one of the greatest barriers for the development of the region. Currently, the main technologies that provide electricity to these communities are diesel generators, batteries and dry cells. These non-renewable energy sources may pose serious problems to the environment and hu

16. THE USE OF BIO-DIGESTERS IN SMALL AND MEDIUM RURAL PROPERTIES WITH EMPHASIS ON VALUE ADDING: A CASE STUDY FROM NORTHWESTERN REGION OF RIO GRANDE DO SUL STATE / O USO DE BIODIGESTORES EM PEQUENAS E MÉDIAS PROPRIEDADES RURAIS COM ÊNFASE NA AGREGAÇÃO DE VALOR: UM ESTUDO DE CASO DA REGIÃO NOROESTE DO RIO GRANDE DO SUL
From the duration of the Kyoto Protocol, there has been a renewed interest in technology of bio-digesters. As they allow a reduction in the emission of greenhouse gases compared to other waste treatment methods, their deployment can permit the marketing of carbon credits, resulting in money. The present study aims to analyze the process of dissemination of t
