If bitcoin mining uses renewable power (and pays for it), is that destroying the world or is that encouraging renewable adoption?

If bitcoin mining uses co2 producing power (because the economics supports it), is that the fault of bitcoin or the government for not sufficiently taxing the negative externalities of that means of production?

Using power is never a net good, regardless of the type of power. If we don't need more power for something specific, the ideal is to just not build more power - consumption is not some noble goal.

Unless we believe that Bitcoin has some use, its power consumption would be problematic even if it weren't so monstrously large. And vanishingly few people believe Bitcoin has any value beyond a get rich quick scheme.

The point isn't to increase the proportion of renewable power, but to decrease the total amount of non-renewable power. 10% renewables is the same as 90% renewables if the remaining consumption is the same total amount.

There is no market in the world where you are going to decrease consumption by increasing the demand. That's just not how economics works.
