Data centers are a high growth and energy-intensive sector of the U.S. economy:
- Can consume up to 100 times more energy than a standard office building.
- Worldwide, use about 30 billion watts of electricity, roughly equivalent to the output of 30 nuclear power plants.
- Responsible for 2.8% of total U.S. energy consumption.
- CO2 emission by data centers worldwide was 80 million tons in 2007 and is projected to increase to 340 million tons in 2020, which will exceed emissions from the airline industry.
The average data center:
- May dissipate as much as 3-6 MW of power in the form of waste heat
- Uses only 5% of the electricity powering its servers to perform computations:
