Worldwide usage of Supermicro high-efficiency solutions could save $2 billion per year in electricity costs, 24 billion kilowatt-hours per year of electricity or the equivalent of 4 billion trees for the sequestration of CO2 emissions (compared to industry average servers).
For example, a datacenter with 1,000 1U high-efficiency servers could save $56K annually in electricity costs, 451 metric tons of CO2, or the equivalent of 166 acres of trees for the sequestration of CO2 emissions.
