There aren’t details on the project of Apple to install a solar array on its billion data center situated in Maiden, North Carolina. All is known is that it will be a 20 MW solar array installation situate on 100 acres of land. In addition, Apple will also be constructing a 5MW fuel cell installation to help power the data center. When completed the installation will run on 100 percent biogas as well as provide 40 million kilowatt hours of energy every year.
The electronics giant has other aces in the sleeve like a white cool roof to reflect sunlight, a chilled water storage system that will transfer 10,400 kWh of power from peak hours to off peak hours daily and during cold weather could funnel outside air. The use of water system and the funnelled air will allow the chillers to be switched off for more than 75 percent of the time. LED lights are equipped with motion sensors and they help too in cutting down on power use.
Apple makes many efforts to have a data center as energy efficient as possible and to conserve the power.
