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.

Supermicro Green Technology and Design
  • Optimized system architecture created to take advantage of Supermicros power saving technology to produce optimal cooling at all application levels
  • Motherboards designed with leading-edge technology based on the latest generation x86 processors and high-efficiency components such as VRMs optimized to reduce energy consumption
  • High-efficiency power supplies designed to run at significantly higher efficiencies of up to 96%+, greatly reducing energy losses
  • Cooling subsystems including advanced technology heat sinks, pulse-width modulated fan speed control, structured chassis airflow design, intelligent temperature and power management, all designed for the most effective cooling for all system components
  • Low-power components such as processors, memory, and HDDs/SSDs

Calculations and Sources

This study outlines the energy costs of data centers and servers worldwide and quantifies the opportunity for improved energy savings through the use of high-efficiency servers. Following is a detailed description of the calculations and information sources. The calculation is theoretical and is not intended to provide precise figures for specific configurations or applications.
