<P> Peak oil is the point at which oil production , sometimes including unconventional oil sources , hits its maximum . Predicting the timing of peak oil involves estimation of future production from existing oil fields as well as future discoveries . The most influential production model is Hubbert peak theory , first proposed in the 1950s . As of 2014 , it is not widely questioned that oil production will be in decline after 2050 . The effect of peak oil on the world economy remains controversial . </P>
