Neobnovljivi izvori energije
Ugalj
Nafta
Zemni (prirodni) gas
Ugalj
• Pre 300 miliona godina planetu zemlju su prekrivale ogromne sume
koje su kasnije prekrile stene I tokom vremena se stvorio ugalj
• Takodje nastaje putem presovanja biljaka
Obrada uglja
• Ugalj se dobija putem Iskopavanja u rudnicima ili putem povrsinskih
kopova
Koriscenje
• Ugalj se koristi za dobijanje elektricne energije,u termoelektranama I
za sagorevanje u domacinstvima
• Rudarski basen Kolubara
• Spavljivanje uglja oslobadja se Dim I pepeo
Nafta
• Nafta je nastala od ostataka zivotinja I biljaka koje su zivele u vodi I
morima
• Nafta se dobija iz busotina u moru
Preradjivanje
• Nafta se preradjuje u rafinerijama, od nje se proizvode
benzin,kerozin,motorna ulja ili dizel
• Sagorevanje ispista vecu kolicinu dima
Opasnost nafte u prirodi
• Ako dodje do prolivanja nafte u prirodi se moze napraviti velika steta
Prirodni gas
• Dobija se u busotinama sa naftom ili u praznim busotinama nafte
• Gasovodom se prenosi do domacinstava ili rafinerija
Sagorevanje gasa
• Prilikom sagorevanja gasa ne ostaje pepeo,ne ispusta se dim niti čađ
• Gas je lako zapaljiv I vrlo otrovan I treba se rukovati sa njim pazljivo
Havla na paznji !!!
