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.
many governments are always looking for reasons to inhibit the progress of bitcoin, we know that the electricity used to mine bitcoin is not so much compared to the power needed by large companies, so this is just a reason that is made, but the bitcoin currency will always evolved because of its global nature, not in one country, but bitcoin is in the whole world.
besides that the use of bitcoin will not affect too much electricity usage, you can use bitcoin on your smartphone, on your computer, or on other gadgets, and everyone also uses gadgets right ? so there's no need to worry about this..
