Apple now uses renewable energy for 75% of its needs

TreeHugger has a post on Apple's green power initiatives - Apple now uses renewable energy for 75% of its needs.
Apple has released its environmental report and, among other interesting things, it now states that is uses 100% renewable energy for its data centers and 75% for its needs overall, up from 35% in 2010. The end goal is 100% renewable energy use for all of the company's energy needs. Its likely that not all that clean energy will not be produced on site, Apple won't turn into a energy utility company, but the equivalent amount would be purchased from other sources and used on the grid, so the end result would be the same (energy is fungible, after all).Of particular interest is the Maiden, North Carolina, data center (which mostly hosts iCloud stuff). It was designed from the ground up to be very energy efficiency and has earned LEED Platinum certification from the U.S. Green Building Council.

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.
