Supercomputers are becoming more energy efficient as the high-performance computing industry readies itself for the more powerful exascale systems of the future. Barcelona Supercomputing Center's MareNostrum 4 Arm cluster is the most energy efficient supercomputer in Europe and ranked 9th in the Green500 world ranking of such machines. The Japanese Shoubu system B ranked number one based on performance-per-watt. Big technology companies are looking to use machine learning and green energy to cool servers. Google’s data centres, for example, use half the energy of a traditional data centre, with the company aiming to become a carbon-neutral company.
