You are completely ignoring the fact that even if connected to the grid all power grids are structured to meet peak demand, and that there will always exist periods of excess power which, until bitcoin, had to go to ground.

Bitcoin makes use of energy that would otherwise be unused.

We don’t operate renewable grids in most of the world, and for most of the world renewable energy supply isn’t great enough to supply the dips without fossil supplements.

All that means is that in almost all scenarios bitcoin mining will be directly causing an increase usage of non-renewable energy. There are of course certain times and places where this doesn’t hold true and there’s a genuine surplus of renewable power that can’t be stored. But that’s an exception not the rule. Try and tell me with a straight face that the majority of power consumed by crypto is surplus renewable energy.
