Our progress toward 100 percent renewable energy.
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.
Digital downloads and environmental responsibility.
Apple data centers deliver a wide range of information and content to your devices — from music and apps to iMessages. When you download a song from iTunes, buy a book from the iBookstore, or install an app from the Mac App Store, there’s no physical media to manufacture, package, and transport. The Apple data centers that provide these digital downloads are among the most energy efficient in the world, and they’re powered by 100 percent renewable energy from onsite and local sources.
Apple data centers host services including iTunes, the App Store, Siri, and Maps.
Maiden, North Carolina
Our data center in Maiden, North Carolina, exemplifies our approach to environmental responsibility. It was designed from the ground up for energy efficiency, and it has earned the coveted LEED Platinum certification from the U.S. Green Building Council — to our knowledge, something no other data center of this size and type has achieved.
In 2012, we completed construction on the nation’s largest end user–owned, onsite solar photovoltaic array on land surrounding the data center. This 100-acre, 20-megawatt (MW) facility has an annual production capacity of 42 million kWh of clean, low-carbon, renewable energy. And we’re currently building a second 20-MW solar photovoltaic facility on nearby land that should be operational in late 2013. In addition, we’ve built an onsite 10-MW fuel cell installation that uses directed biogas and provides more than 83 million kWh of 24/7 baseload renewable energy annually — it’s the largest non-utility fuel cell installation operating anywhere in the country. All told, Apple will be producing enough onsite renewable energy — 167 million kWh — to power the equivalent of 17,600 homes for one year.* These power sources are connected to the local energy grid and not only displace other dirtier forms of electricity that otherwise would have been used, but their environmental benefits are used only by Apple and are in addition to any locally mandated renewable energy requirements.

Energy-efficient design elements
- 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
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.
Like our facilities in Maiden and Prineville, our data center in Newark is being powered by 100 percent renewable energy. We hit this milestone in January 2013, when we began serving the data center with energy sourced primarily from wind power. We’re procuring this energy directly from the wholesale market through California’s Direct Access program.
Newark Energy Sources
100% clean, renewable energy, sourced primarily from wind power.
Our experiences in Maiden, Prineville, and Newark will help ensure that our next data center, to be located in Reno, Nevada, will live up to the same high standards for environmental responsibility. In Reno, we will take advantage of Nevada’s excellent natural solar radiation and geothermal resources to completely meet the energy needs of our data center.
Reno Energy Sources
100% renewable energy, generated by onsite solar array and geothermal.
Our commitment to renewable energy.
Renewable energy throughout Apple.
Data centers are just part of the renewable energy story at Apple. We’re investing in plans to achieve net zero throughout Apple — using 100 percent renewable energy and generating zero emissions at all of our facilities around the world. At our headquarters in Cupertino, for example, we’ve rolled out a biogas-powered fuel cell and built rooftop solar photovoltaic systems at two building sites. We’ve also cut energy use by over 30 percent at a time when occupancy increased by more than 12 percent. As a result of all our work, we’ve increased the proportion of renewable energy used throughout Apple from 35 percent in 2010 to 75 percent at the end of 2012.
Our guiding principles.
As we seek renewable energy for our facilities around the globe, we’re guided by three principles. First, we want to make sure that any clean, renewable energy we create must add to that already mandated by local regulations. Second, we want to displace dirtier forms of energy with clean energy that will make a difference in the communities where we do business. And third, we rigorously measure and report our energy use to ensure that there is no double counting — that only Apple has consumed these renewable resources. Whenever possible, we use the same renewable energy tracking systems that utilities use to demonstrate their compliance with renewable energy mandates.
