"...helped the adoption of renewables and made them cheaper." How so?

Miners are chasing profit margin so they'll use whatever's cheapest. If that's renewable where some of them are, so be it. And if everyone else start reducing use of coal and that becomes cheap, miners who exploits that to derive higher profit margin will grow faster I imagine.

I would attribute growth and economies of scale that renewables have achieved to renewable proponents, industries, government subsidies and loan prorams. Crypto miners are energy consumers and some of them use renewable energy. But how do we go from there to miners being some kind of force for good in this context?
