physics and math, pretty much works each and every time unless you're
stuck with having to use some hocus-pocus conditional physics that
doesn't take little pesky things like the actual truth into account.

64,000 teraWatts of terrestrial solar energy is conservative.

That's what makes the earth function.


There's actually lots more solar energy that doesn't manage to get
sufficiently through our polluted plus somewhat wet and reflective
atmosphere,

No, the above figure includes all of that.

The problem with solar energy is the huge cost of harnessing it for man's needs.
Not to mention that you only get that energy when the sun shines.


so perhaps as such it doesn't hardly count. Of orbital
physics that relates to working against the mutual pull of gravity is
exactly what it is. In the case of the Earth/moon consideration it's
worth roughly 2e20 joules per each and every second, and the last time
I'd checked there were still 3600 of them seconds per hour.

There's no ENERGY required to keep the moon in orbit. The moon is held in place
by a gravitational FORCE. Force is not the same thing as ENERGY ! This is where
your clear lack of scientific education results in you making idiotic
statements.

The tides that the moon creates do have energy but it isn't easily or
economically tapped.
