Apple Data Centers Plan to be Totally Green

0

Apple said it’s committed to reducing its environmental impact and to lowering its carbon footprint. The company said it now derives 75 percent of its power from renewable sources — up from 35 percent in 2010.

In updating its progress toward 100 percent renewable energy Apple’s website noted:


Our goal is to power every facility at Apple entirely with energy from renewable sources — solar, wind, hydro, and geothermal. So we’re investing in our own onsite energy production, establishing relationships with suppliers to procure renewable energy off the grid, and reducing our energy needs even as our employee base grows.

Our investments are paying off. We’ve already achieved 100 percent renewable energy at all of our data centers, at our facilities in Austin, Elk Grove, Cork, and Munich, and at our Infinite Loop campus in Cupertino. And for all of Apple’s corporate facilities worldwide, we’re at 75 percent, and we expect that number to grow as the amount of renewable energy available to us increases. We won’t stop working until we achieve 100 percent throughout Apple.

About Prineville the company noted:

Our newest data center, currently under construction in Prineville, Oregon, will be every bit as environmentally responsible as the one in Maiden. Oregon allows the direct wholesale purchase of renewable energy through Direct Access, and Apple is using this program to opt out of the default grid mix and directly access local renewable energy sources, such as wind, hydro, solar, and geothermal power — enough to power the entire facility. As a result, we’re working with two local utilities as well as a number of local renewable energy generation providers both to create Apple-owned renewable energy sources and to invest in and purchase other local renewable energy.

Prineville Energy Sources

Locally sourced renewable resources, including wind, hydroelectric, and solar.

The company lists energy-efficient design elements include:


  • A chilled water storage system to improve chiller efficiency by transferring 10,400 kWh of electricity consumption from peak to off-peak hours each day
  • Use of “free” outside air cooling through a waterside economizer operation during night and cool-weather hours, which, along with water storage, allows the chillers to be turned off more than 75 percent of the time
  • Extreme precision in managing cooling distribution for cold air containment pods with variable-speed fans controlled to exactly match airflow-to-server requirements from moment to moment
  • Power distributed at higher voltages, which increases efficiency by reducing power loss
  • White cool-roof design to provide maximum solar reflectivity
  • High-efficiency LED lighting combined with motion sensors
  • Real-time power monitoring and analytics during operations
  • Construction processes that utilized 14 percent recycled materials, diverted 93 percent of construction waste from landfills, and sourced 41 percent of purchased materials within 500 miles of the site
