Não de qualquer jeito

While President Lula said that Brazil has responded to the future energy challenge by "using clean, renewable, alternative energy sources to an ever-greater extent", Brazil seems to favour increasing fossil-fuel power generation. For example, coal, diesel oil and natural gas-fired thermoelectric plants will supply about two-thirds of the 3,200 megawatts of new electric power which was put out to bidders by the Brazilian government last December. Once built, these plants will emit over 11 m tonnes of CO2 per year - an 11% growth, which is not only bad for the global climate but also for the national economy.

...if Brazil were to implement an aggressive energy efficiency policy it could reduce the growth in power demand by as much as 40%, achieve energy savings of more than $37bn per year, and stabilise its power-sector related CO2 emissions by 2020. This may seem radical, but in 2001, under the threat of power blackouts, Brazilians slashed electricity demand by 20% in a couple of months, without reducing their quality of life.
