I don't see this happening for a very long time. Mines and oil and gas wells are huge wealth concentrators.

Oil wells decrease in production over time. It's called the decline rate. For wells in the Permian basin, the average decline rate is about 15%. So a 1000 barrel per day ("bpd") well produces ~850bpd in year 2, ~700bpd in year 3 and ~550bpd in year 4. That means you need to be constantly drilling wells. That's more wealth concentration opportunity.

1MW of solar produces 1MW in years 1 through 20.

Additionally, the fight for control over resources induces demand for weapons. Solar doesn't do that. This is summed up as No one goes to war over a solar panel [1].

Efficiency isn't the goal. Wealth extraction is.
