Le Pétrole
Le pétrole est une huile minérale d’origine naturelle composée d’une multitude de composés organiques, essentiellement des hydrocarbures, piégée dans des formations géologiques particulières. Il permet, une fois raffiné, de produire divers carburants, comme l’essence ou les diesels, des gaz, butanes et propanes et divers combustibles. Il est classé dans les ressources énergétiques fossiles. Source : wikipedia
