What is being proposed is some community effort to standardize & promote this approach, because if we manage to make Bitcoin green(er) - we will remove what many commentators see as the last barrier / biggest risk to even wider Bitcoin adoption.


The point of avoiding centralization is to avoid authorities --- who can end 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 go 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 the sun has a much larger total mass than Earth itself, thus it is a "more renewable" 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 design of Bitcoin at a fundamental level and risk introducing unexpected side effects (bugs).
