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

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
