Apple's annual developer conference in San Francisco.
Greenpeace Activists Protest at Apple's Irish Offices over Data Center Energy Use
It appears, however, that Greenpeace's assessment of Apple's energy use was based on flawed assumptions, and Apple stands by its claims that its new data center in Maiden, North Carolina and a forthcoming one in Prineville, Oregon will be among the cleanest in the world.
Greenpeace estimated that the Maiden facility would require 100 megawatts of power at peak capacity, claiming that Apple's proposed solar and fuel cell facilities at the plant would provide only 10% of the center's energy needs. The group's report also appears to assume that the Prineville facility will run on dirty power sources, and those two assumptions were combined to give Apple a low "clean energy index" score of 15.3% and estimate Apple's share of data center power usage derived from coal at an industry-high 55%.
Apple quickly responded to the Greenpeace report, issuing statements to several media outlets claiming that the Maiden data center requires only 20 megawatts of power at peak capacity and that the renewable energy sources being built at the site will provide at least 60% of the center's power needs. In addition, Apple notes that the Prineville data center is planned to run on 100% renewable energy.
“Our data center in North Carolina will draw about 20 megawatts at full capacity, and we are on track to supply more than 60% of that power on-site from renewable sources including a solar farm and fuel cell installation which will each be the largest of their kind in the country,” Apple said in a statement. “We believe this industry-leading project will make Maiden the greenest data center ever built, and it will be joined next year by our new facility in Oregon running on 100% renewable energy.”For its part, Greenpeace believes that Apple is continuing to obfuscate its energy numbers and release only those that make the company appear in a positive light. And so despite Apple's claims regarding significant efforts to minimize the impact of its data centers on the environment, Greenpeace believes that the company should be doing more to publicly lead the way toward further adoption of renewable energy sources.
