Geothermal cooling brings down data center temperatures

Cooling is the process of moving heat energy from one place to another. Traditional cooling requires energy to power mechanical refrigeration, but geothermal cooling uses the subterranean earth as a big heat sink.

The ground below us generally stays cooler than the surface and keeps a constant temperature year-round. Rather than use a heat exchanger to cool a data center using ambient air or local water -- which can fluctuate significantly with the time of day or season -- data center designers are using heat exchangers and naturally cooler air from underground.
