• CO2 mitigation
• Electricity generation
• Marginal abatement cost curves

The present study presents an analysis of the options available for the mitigation of CO2 emissions in the Brazilian power sector. The objective is to verify the potential use of wastes for electrical energy generation and its competitiveness in comparison with other sources of renewable energy. A comparison was made using marginal abatement cost curves derived from a reference scenario obtained from earlier studies dealing with the expansion of the Brazilian power sector. The results showed that the availability of wastes is significant and that they can be used at a cost 20-60% lower than that of wind power generation, a subsidized source of energy in Brazil. It can therefore be concluded that it would be more efficient if incentives were applied to the use of wastes for electrical power generation since it offers socio-environmental benefits which go far beyond the reduction of CO2 emissions.
