I just read this on a Macedonian site, I don't know how reliable is it, but I though I'd share it.
(Here's the source if you want to make sure I'm not bullshitting, lol)
I translated it to English so there might be some mistakes and it won't sound professionally written for sure.
"People will use the last drop of oil on June 22, 2048 at 8:58 PM.
The natural gas will disappear 21 years later, November 2, 2068 at 9:25AM to be exact.
These are the calculations of the EU's energetic portal in which it is claimed that the Saudi Arabia, Iran, Iraq, Kuwait, Venezuela, UAE and Russia have the largest amounts of oil and gas reserves
According to the same source, China is the country using the most oil."
