And when is  that going to happen, when we are left with no oil for the coming generations. Actually the need of the hour is to consume the non renewable sources of energy in an efficient and meaningful way without being harsh with them. But we are not able to realize this fact and we are continually destroying our resources. The coming generations will not be left with anything but will only curse us. The time sis not too far when we will be faced with the situation of world war III only on the issue of ENERGY CRISIS!!The data regarding the energy consumed during bitcoin mining has really left me awe struck. Like I had an idea that mining bitcoin requires huge consumption of energy but this much value is really shocking. I really hope that the realization of saving the environment soon dawns upon the mankind and some concrete efforts are being taken up ASAP!!
