“…Resource assessments in high spatial resolution have been provided for solar global horizontal irradiation [14,15], direct normal irradiation [16] and wind speed [17], revealing that particularly good potentials are located in the western and northwestern part of the country. With reservoir hydro stations as a source of flexibility, the power system is expected to easily balance substantial shares of VRE generation without increasing demand for fossil backup power plants [5,[18][19][20]. Nevertheless, Saporta [21] mentioned that the flexibility provided by hydropower plants with reservoirs in Brazil can be constrained by the multiple uses of water for environmental, social and economic purposes.…”

Abstract:With its abundance of renewable energy potentials, not only for hydropower and bioenergy, but also for wind and solar, Brazil provides good prospects for a carbon neutral energy system. The role of an enhanced coupling of the power, heat and transport sectors in such systems is not yet fully understood. This paper analyses the least-cost composition and operation of a fully renewable power supply system as part of a carbon neutral energy supply in Brazil. It relies on the application of the high-resolution energy system model REMix. Our analysis reveals that the expansion of wind and solar power is more cost-efficient than the construction of additional hydroelectric plants. This is favoured because the existing hydroelectric plants offer large capacity of dispatchable power to compensate for fluctuations, and thus no additional storage is necessary. Furthermore, the REMix analysis indicates that varying shares of solar and wind power technologies as well as the spatial distribution of power generation have only a small influence on supply costs. This implies that the transformation strategy in Brazil can be primarily based on other criteria such as regional development, public acceptance, environmental impact or industrial policy without major impacts on system costs.

“…A introdução de um preço pelas emissões de GEE poderia promover o uso de fontes renováveis (LOSEKANN et al, 2013). Apesar da necessidade de reduzir as emissões de GEE para atender os compromissos internacionais assumidos pelo Brasil, o plano energético oficial para 2030, preparado para o governo brasileiro, prevê um aumento relativo na geração térmica utilizando gás natural, carvão e energia nuclear (RICOSTI;SAUER, 2013).…”

RESUMO ABSTRACTO estado do Paraná é líder na geração nacional de energia elé-trica, respondendo por 16,74% da produção, sendo também um grande consumidor de energia elétrica, participando com 6,22% em escala nacional. A energia elétrica é responsável pela emissão de gases de efeito estufa (GEE), dentre os quais o dióxido de carbono (CO2) é o mais expressivo. Este trabalho quantificou e analisou as emissões de CO2 associadas ao consumo de energia elétrica no estado do Paraná no período 2010-2014. Dados do Anuário Brasileiro de Energia 2015 e de fatores de emissão do Sistema Interligado Nacional (SIN) foram empregados para os cálculos. Estimou-se as emissões em 2010 em 1,3 milhão de toneladas de CO2 equivalente (CO2e), a qual saltou para 4,1 milhões em 2014. Esse aumento expressivo se deve a três fatores: o aumento da população, do consumo per capita de eletricidade e do maior fator de emissão do SIN brasileiro no período devido ao uso mais intenso de fontes não renováveis na matriz elétrica. Concluiu-se que as emissões de CO2e associadas ao consumo de energia elétri-ca no estado triplicaram em 5 anos e que há necessidade de reforçar a participação de energias renováveis para frear essa tendência nos próximos anos.Paraná State is the national leader of electricity generation in Brazil, accounting for 16.74% of the national production, being also a major consumer of electricity, accounting for 6.22% nationwide. Electricity is responsible for greenhouse gases emission (GHG), of which carbon dioxide (CO2) is the most significant. This study quantified and analyzed the CO2 emissions associated with the electricity consumption in Paraná State during 2010-2014. Data coming from the Brazilian 2015 Energy Yearbook and emission factors of the National Interconnected System (SIN) were used for the calculations. It was estimated that the emissions in 2010 were 1.3 million tons of CO2 equivalent (CO2e), which jumped to 4.1 million in 2014. This significant increase is due to three factors: population growth, increase in per capita consumption electricity and increased Brazilian SIN emission factor in the period due to the remarkable augment of non-renewable sources use in the energy matrix. It was concluded that CO2e emissions associated with electricity consumption.PALAVRAS-CHAVE: Efeito estufa, Eletricidade, Fator de emissão, Impacto ambiental.
