The environmental group Greenpeace has issued a report raising questions about Apples commitment to using 100 percent renewable energy sources to power its facilities, particularly a new data center Apple opened in Maiden, N.C.
Greenpeace rescored Apples performance, updating an April analysis of the clean energy performance of Apple and several other companies, all of which have some or all of their operations based in the cloud. The other ranked companies range from Hewlett-Packard, IBM and Microsoft to Facebook, Twitter and Google.
Despite a welcome commitment by Apple in May that its data centers will be coal-free and powered by 100 percent renewable energy, the analysis reveals that Apple still lacks a plan that outlines a realistic path to eliminate its reliance on coal to power its iCloud, Greenpeace stated in a July 12 news release.
Apple iCloud is a service that allows users to back up data on their Macs, iPads, iPhones and other devices to the cloud, which operates from the North Carolina data center.
A large section of Apples own Website is devoted to its environmental commitment and practices. On it, Apple states four of its data centersin Austin, Texas, Sacramento, Calif., Munich, Germany, and Cork, Irelandare 100 percent powered by renewable energy. As to the North Carolina data center, our goal is to meet the needs of the Maiden facility using 100 percent renewable energy by the end of 2012, Apple has stated. We have major projects under way to achieve this goalincluding building the nations largest private solar arrays and building the largest operating non-utility fuel cell installation.
But Greenpeace is skeptical that Apple can reach that goal and noted that Duke Energy, the utility that serves North Carolina, still relies mostly on coal and nuclear power for electrical generation and that only 4 percent of its generating capacity will come from renewables by 2030.
Greenpeace is calling on Apple to use renewable electricity from onsite generation to directly power its North Carolina facility and use grid power from Duke Energy only for backup. It also is urging Apple to use biogas to directly power fuel cells at the Maiden data center and to invest directly in new renewable energy generation in North Carolina rather than buying renewable credits to green Duke Energys dirty electricity. The group also wants Apple to use its leverage as a major Duke Energy customer to get the utility to use more renewable energy sources and to make access to renewable energy sources a top priority in siting future Apple data centers.
The Greenpeace report assigns each company studied an overall Clean Energy Index, expressed as a percentage, and records the use of coal and nuclear sources for the electricity it consumes. It also grades companies on the transparency of their energy use disclosures, how they site their infrastructure, their energy efficiency and greenhouse gas mitigation, their use of renewables and their clean energy advocacy.
Apple actually improved some of its performance in the July rescoring of the April report. Its Clean Energy Index improved to 22.6 percent from 15.3 percent, its use of coal-generated electricity fell to 33.5 percent from 55.1 percent and its use of nuclear fell to 11.6 percent from 27.8 percent.
Greenpeace says its next going to rescore the Clean Energy Index for Amazon and Microsoft later this year.
