Within the interesting debate, I found an essential point missing, which was just mentioned by bbc.reporter and which was discussed yesterday in another thread on the subject.
1. They might begin to try doing it more quickly not because of climate change, it might be because of concerns on energy shortages.
The desire to cast Bitcoin in a bad light because of the PoW's energy use predated the war in Ukraine and the energy problems that Europe is facing, which not only consist of a huge price increase, but also the prediction of power cuts this winter.
The E.U. is preparing for blackouts this winter, amid an energy crisisIf you are talking about cutting off electricity in winter, it will be for what are considered non-essential services, as for example hospitals must have a continuous supply of electricity.
If the public authorities consider bitcoin mining not only non-essential, but an attack on their power, we know how this is going to end.
