What is being proposed is some commu= nity effort to standardize=C2=A0& promote this approach, because if we mana= ge to make Bitcoin green(er) - we will remove what many commentators=C2= =A0see as the last barrier / biggest risk to even wider Bitcoin adoption. The point of avoiding centralization is to avoid authorities --- who can en= d up being bribeable or hackable single points-of-failure, and which would = potentially be able to kill Bitcoin as a whole from a single attack point. Adding an authority which filters miners works directly against this goal, = regardless of however you define "centralization" --- centralization is not= the root issue here, the authority *is*. One can observe that "more renewable" energy sources will, economically, be= cheaper (in the long run) anyway, and you do not have to add anything to g= o towards "more green" energy resources. After all, a "non-renewable" resource is simply a resource that has a lower= supply (it cannot be renewed) than a "more renewable" energy source. There is only so much energy that is stored in coal and oil on Earth, but t= he sun has a much larger total mass than Earth itself, thus it is a "more r= enewable" energy resource than coal and oil. Economically, this implies that "greener" energy resources will be cheaper = in the long run, simply by price being a function of supply. In short: trust the invisible hand. We already know that lots of miners already operate in places where energy = prices have bottomed due to oversupply due to technological improvements in= capturing energy that used to be dissipated as waste heat. What is needed is to spread this knowledge to others, not mess with the des= ign of Bitcoin at a fundamental level and risk introducing unexpected side = effects (bugs). Regards, ZmnSCPxj
