Renewable and Non-Renewable Exergy Cost and Specific CO2 Emission of Electricity Generation:The Brazilian Case
The average unit exergy cost and CO2 emission of the electricity generated in Brazil are evaluated using the national electricity mix and considering the representative profiles of the electricity generation processes.The Brazilian installed capacity is composed of hydropower plants,natural gas,fuel oil and coal thermoelectric plants,biomass cogeneration plants,nuclear plants and wind farms.By using exergoeconomy methodology to distribute exergy costs and CO2 emissions in multiproduct processes and by weighting the CO2 emissions and the renewable and non-renewable exergy consumption of each type of plant it is possible to obtain the average unit exergy costs and specific CO2 emission for the whole electricity generated.An interactive system is used to take into account the processed fuels and cyclic electricity interactions.The renewable and non-renewable exergy costs together with the CO2 emissions provide a reasonable way to compare the electricity and its final applications with other energy sources.
