> Also, what good is the added capacity if it's being used up by bitcoin? The new capacity replaces the old capacity, which replaces fossil fuel power plants, which eliminates carbon emission output. > On the other hand, if we capture that energy and turn it into heat, which is essentially what bitcoin does, we're adding heat to the planet that, as you would have pointed out, wouldn't stay here in the first place. I think you need to review some physics, the sun's rays are already hitting the planet, causing "heating". This is inconsequential because it dissipates naturally. Capturing the sunlight and turning it into energy in no way introduces more energy to the planetary equilibrium. The problem is carbon emissions causing feedback mechanisms by trapping heat.
