Real heat-—yes it does. But if you do the whole math problem you’ll need a lot of zeros. Then remember this in terms of how puny the works of humanity are:

If you add up all the energy humans use: take your monthly power bill, double it to cover farming, manufacturing, etc. then multiply by 6 billion, You get a number that approximates the solar Impact on a county in, oh, say Kansas.

Another fun comparison, slightly related, is to divide the Area of the State of Texas by the 6 billion population. You notice that the hole bunch could each have 4,000 Sq. Ft. to live on in Texas. Then the solar energy that falls on a county in Kansas could power the whole operation.

But you didn’t finish the first problem. Multiply the Square Yardage by 300 watts per Yd. Or step up to megawatts to save zeros.

I once built a I yd parabolic mirror to prove the concept/math. That thing was scary powerful. It could melt a pound of lead in about 20 minutes. It could also fryyourass if you got in front of it while pointed at the sun.
