Atleast once a day I'm going to post a new fact, explain it, and give you a link to a more in depth explanation.
At current consumption rates we have 40 years worth of oil left.
Oil is used in everything from driving cars to being used in chemicals like paint.
I don’t think we have to worry too much though, because we are researching into cleaner/renewal sources for energy such as Hydrogen power - Hydrogen is the most abundant chemical on Earth (Water molecules are made of two parts hydrogen).
