We as supporters of bitcoin already know that it's totally a false allegation over bitcoin that it consumed the highest electrical energy for mining operations.Critics just want to target bitcoin by any means.Also even if it consumed higher energy,its not related to coal and mostly hydro electric power.
From here we should also have a new plan. To reduce the load on the power instead of it by another energy. Use the energy of the wind or the power of the flow. It is also considered to be a solution to make bitcoin more stable.
