This narrative is spread by people who don't like Bitcoin and they accuse that bitcoin mining only leads to environmental damage. They often say that the electricity used in bitcoin mining should be diverted to other more important things and that it only worsens global warming because most of the energy comes from non-renewable energy. However, this is just misleading, because bitcoin mining is already much more efficient and effective. Bitcoin mining companies also use renewable energy and keep their mining more environmentally friendly and transparent to everyone. The efforts made by bitcoin miners are actually much better compared to the efforts made by the banking or textile industries, which use much more energy and are inefficient.
