1. Since 2.000 until 2.015, the oil was the most produced fossil fuel in Brazil. In 2.015, it was about 132.8 Mtoe of oil, followed by bio/waste with 86.2 Mtoe, Hydro and Gas production with less than 36Mtoe each one. Before 1991, the dominant fossil fuel it was the bio/waste with 47.4 Mtoe, followed by oil production with 33.0 Mtoe. 2. According to the diagram, the final consumption in those decades indicated that the most of the bio/waste production it was used in the industry and oil produced it was used in transport. In 1.991, approximately 24.6 Mtoe of the Oil produced was spent in Transport, specifically on a road. 3. I believe that to improve the environmental friendly and sustainable sources it is needed to create economic advantages for those investors (public or private) that can bring more technology. In addition, we can study the climate and conditions to apply this new technology in high scale for all the country because it is essential to produce clean and renewable energy to keep the cycle, the energy flows, without creating more pollution. Please, see the picture from "Itaipu Binacional", the biggest hydroelectric dam in Foz do Iguaçu City.
