The Earth’s angular momentum is the exact opposite of renewable. It’s even less renewable than so-called fossil fuels.

True, but it's being wasted anyway. The amount of power dissipated in the daily tides is around 3.75 terawatt, around 3 million times as much.

And don't assume this 1.2 MW adds to that total, a good portion of it is simply substituted.

??? by that metric literally nothing in the universe is renewable.

RENEWABLE ENERGY IS IN VIOLATION OF THERMODYNAMICS. WE ARE ALL HEADING TOWARDS THE HEAT DEATH OF THE UNIVERSE.
