Unfortunately, Brazil as a little use of alternative energy sources. Much of the electricity generated, has its origin within hydroelectric plants. This is a big national problem, because in cases of water crisis caused by lack of rain, can cause the need of power rationing in addition with price increase. Although, the use of an ethanol program, the country is still very dependent on fossil fuels (petrol and diesel) to supply the vehicle fleet. Besides being air pollution factors, are also non-renewable energy sources.
The good news are, that is increasing in Brazil in recent decades, the use of two important alternative energy sources: wind and solar. It is expected that the country can grow in the coming years, with the use of these alternative sources in its energy mix and as to rely on companies to support and to design the systems.
