How many gallons does of petroleum based products (gasoline, diesel, jet fuel and many other uses) does the entire world use every second?

First of all, I asked Grok (follow this link for a deeper dive):

Global oil demand (including both fuel and non-fuel uses) is currently around 104.6 million barrels per day.

Approximately 84% of this demand is for fuel uses (energy consumption), while the remaining 16% is for non-energy purposes like petrochemical feedstocks, lubricants, and asphalt. This ratio is derived from comparing IEA’s reported energy consumption from oil (193 EJ in 2024, equivalent to ~86.4 million barrels per day) against total oil demand (102.8 million barrels per day in 2024), and scaling proportionally to current levels.

Fuel demand = 104.6 million barrels/day × 0.84 ≈ 87.9 million barrels/day.
Convert to gallons per day: 87.9 million barrels/day × 42 gallons/barrel ≈ 3.69 billion gallons/day.

Convert to gallons per second: 3.69 billion gallons/day ÷ 86,400 seconds/day ≈ 42,732 gallons/second.

Next, I’ll leave you with this shocking visual that pertains to the oil produced only by Kuwait every second:

I’m reminded of a comment made to me by an engineer who worked in the field of petroleum. He said it is perhaps the greatest achievement of human beings to be able to extract as much petroleum for use by human beings at such a moderate cost per gallon.

I’m also reminded of the many people who claim that we can replace all of this oil usage with wind and solar. I am skeptical of that claim when I read of the immense volume of oil we use.
