Koyla, petroleum aur prakritik gas ko fossil fuels kehte hain. Ye laakhon saal pehle zameen ke neeche dabe paudhon aur jaanwaron ke avsheshon se garmi aur dabaav se dheere-dheere bane.

Hum inhe bahut use karte hain: petrol aur diesel gaadiyaan chalaate hain, koyla bijli ghar mein jalakar bijli banti hai, aur LPG (petroleum se) khaana banaane mein. Plastic bhi petroleum se banta hai.

Fossil fuels banne mein laakhon saal lagte hain, isliye ek baar khatam to gaye: ye non-renewable hain. Inhe jalaane se hawa bhi pradooshit hoti hai. Isliye inhe dhyaan se use karein aur dhoop, hawa aur paani ki urja ki taraf badhein.
