What is Peak Oil?

Peak Oil is the point when the supply of earth oil is no longer available for our energy needs. Oil is occur naturally in earth so it is called natural resource. We use petroleum oil as an energy source. It is not a renewable energy such as solar energy. According to source "The peak date is near future but there is still a doubt, due to our inability to take properly stock of oil supplies right now".
