Increase in Luminosity of the Sun Over Time

Updated Jul 9, 2023

Sun’s current output: $3.8*10^{26}W$

It increases luminosity by 1% every 100 million years. That’s an increase of $3.8*10^{16}W$ per year, for several billion years…

Assuming each person needs a very generous 1MW of energy, the energy increase from the sun alone is enough for $3.8*10^{10}$, 38 billion, more humans each year.

Production rate would likely be much higher in the expansion phase until we reach solar limits and the plateau rate above.
