In fact, we need examples from all over the world because the EU is keen to develop a global approach:
„States shall implement targeted and proportionate measures to lower, and must be ready to stop, the electricity consumption of crypto-asset miners, in line with the proposed Council Regulation on an emergency intervention to address high energy prices. International cooperation shall be fostered “to tackle the issue of the high energy consumption of PoW mining in a globally impactful way.”
The EC wants to “collaborate internationally with different standardization bodies to develop the energy-efficiency label.”
