Desc: Mundo Escondido: Directed by Jose Menezes. With abundant sources and favorable climate, Brazil has an energy potential still unknown. The documentary seeks to show the ability to produce our own energy in a domestic and clean way; models in other countries; the positive reflexes of this behavior in environmental, political and economic spheres; and to unravel the reasons why, although technologically feasible, this model has not yet been inserted in the country.
