Although the first supercomputers might not stand a chance even against the smartphones of today, nevertheless, they too have evolved like everything else. With their supernatural computational and analytical abilities, they light the way for the computers of the coming generation. However, just like their abilities, the requirements of the supercomputers are also extreme. Even simple computers have high electricity requirements. Supercomputers take this to a brand new level. You need a range of air conditioners, coolants to keep them cool. Add to that their operational costs and you have a very huge carbon footprint. Nevertheless, so as to one day make more computers of this capacity for commercial purposes, companies are coming up eco-friendly supercomputers to tackle this problem.
