>One single square meter of land in direct sunlight receives a constant 6kW (21MJ) of energy. The heat rejected by industrial and other processes is absolutely minuscule in comparison, a rounding error.

This is incorrect, at ground level its about 1 kW of sunlight per square meter if that square meter is orthogonal to the line of sight to the sun, otherwise it gets diminished with cos(theta) where theta is the angle between the line of sight to the sun and the normal of the square meter of land, it can not receive 6 kW no matter the orientation. And 6 kW is a power, while 21 MJ is an energy.

Indeed your incorrect comment in an authoritative voice might get downvoted, for good reason, but I won't be the one doing it...

Welp, turns out I should verify information better. I thought 6kW seemed high when a 1 square meter solar panel that is ~25% efficient can generate 250W of electricity. My apologies.
