Grow Your Own Virtual Forest and Save $4 Billion/Year Worldwide

Worldwide usage of Supermicro high-efficiency solutions could save up to $3.8 billion per year in electricity costs, 38 billion kilowatt-hours per year of electricity or the equivalent of 6 billion trees compared to the servers in use in today's data centers.

For example, a datacenter with 1,000 1U high-efficiency servers could save up to $84K annually in electricity costs, 700 tons of CO2, or the equivalent of 200 acres of trees for the sequestration of CO2 emissions.
