Back in the 40’s or 50’s it was estimated that the Earth could easily support 40 Billion people..................
That I have no doubt, I have big doubts about the current numbers is all.
“Back in the 40’s or 50’s it was estimated that the Earth could easily support 40 Billion people..”
Uh not just no but hell no.
If 40 billion humans consumed energy at American levels, they would use approximately 10,640 exajoules of energy annually.
[Average U.S. per capita energy consumption: Approximately 266 gigajoules (GJ) per year. This is equivalent to 0.000266 exajoules (EJ) per year, as 1 exajoule = 1,000,000 gigajoules.]
^^^^ multiply this by 40 billion.
the total world primary energy consumption from all sources in 2023 was approximately 604 exajoules. 80% of that was fossil fuels with a limited supply.
one exajoule (EJ) is equivalent to approximately 174 million barrels of oil equivalent (boe).
10,640 exajoules of energy annually the equivalent is 1.85136 trillion barrels of oil per year equivalent.
NO FING WAY does the industry produce that level of oil for a single year.
Global technically recoverable oil at any price is estimated at around 1.6 trillion barrels, while proven reserves are approximately 1.65 trillion barrels, and unproven (undiscovered) reserves are estimated to be around 3 trillion barrels.
Yeah no way 40 billion the world is going to struggle with 9 billion when not if they demand even EU levels of energy consumption..
