An earlier study (Szklo A, Soares J, Tolmasquim M. Economic potential of natural gas-fired cogeneration in Brazil: two case studies. Applied Energy 2000;67(3):245-67) that assessed the economic feasibility of gas-fired cogeneration systems in Brazil, indicated that the use of cogeneration in...

This study aims at estimating the abatement costs of CO2 emissions of the Brazilian oil refining sector. For greenfield refineries that will be built until 2030, mitigation options include the modification of refining schemes and efficiency gains in processing units. For existing refineries and...

This paper examines the sources of changes in energy use of the Brazilian economy of industries and households from 1970 to 1996, using structural decomposition analysis based on the logarithmic mean divisia index technique. Energy use can be decomposed into eight factors that explain changes in...

This study tests the assumptions that justified the establishment of the Brazilian Biodiesel Production Program (PNPB), to see whether this program has achieved its promised results. Given the connection between socioeconomic, political, technological and environmental issues, the study performs...

Recent restructuring of Brazil's power sector, allied to the expected larger share of natural gas in the nation's grid and the cost reductions of gas-fired power generation technologies, has introduced a set of situations apparently favorable to the expansion of natural gas-fired cogeneration....
