It's admittedly super rough. I googled worldwide labor market and got 3.5billion workers. I then Googled average global earnings, $20k. However i'll admit to a mistake. The second number appears incorrect and it seems it should have been ~$10k based on the following: https://www.zippia.com/advice/average-income-worldwide/#:~:t....

Still i think the point should stand no matter how precise we get here. The cost of labor absolutely dwarfs the cost of electricity. That was what i wanted to hit on while completely acknowledging the numbers are rough.
