Call it the battle of Maiden. This week, Apple and Greenpeace traded very public barbs over how much clean power is used by Apple’s $1 billion state-of-the-art data center in Maiden, N.C.
But it appears that much of the arguing stems from their inability to agree on what they’re arguing about.
On Monday, Greenpeace released a report calling Apple’s data center a power-hungry threat to the environment, but Apple responded by saying Greenpeace got its facts wrong. The key sticking point is a simple question: How much energy is Apple’s data center burning? Greenpeace says 100 megawatts, while Apple says it’s only 20 megawatts.
The truth may be somewhere in-between.
According to Greenpeace, Apple’s data center relies too much on coal-produced electricity, and the company hasn’t done as much as it could to secure other, more environmentally friendly sources of power. They’ve even produced a video to make the point:
[vodpod id=Video.16396490&w=425&h=350&fv=videoId%3D1569766320001%26amp%3BplayerID%3D1813626064%26amp%3BplayerKey%3DAQ%7E%7E%2CAAAAAF1BIQQ%7E%2Cg5cZB_aGkYZXG-DCZXT7a-c4jcGaSdDQ%26amp%3Bdomain%3Dembed%26amp%3BdynamicStreaming%3Dtrue]
Apple is clearly unhappy with the report. After all, it’s adding some unprecedented green-energy generating features to the site, including a massive solar array on the site along with a five-megawatt biogas generator. “We believe this industry-leading project will make Maiden the greenest data center ever built,” said Apple spokeswoman Kristin Huguet in an email message.
She added that 60 percent of the 20 megawatts used by the facility will come from the site’s solar farm and biogas-powered fuel cells. About five megawatts of that will come from the fuel cells, and the other seven from the solar array.
So why the disconnect? Greenpeace says it got the 100 megawatt number by doing a simple calculation: one megawatt of power demand for every $15 million spent on the data center plus 50 percent extra for non-computer energy demands. Apple, they add, has said it plans to spend $1 billion at Maiden over the next decade.
But that $1 billion figure isn’t exactly the right number to use when compared to Apple’s 20 megawatt figure. When it announced the Maiden facility last year, Apple pegged its investment at $500 million. The company has reportedly told local officials that it expects to invest a total of $1 billion on the site over the next decade — presumably to pay for the green energy initiatives and maybe even building a second data center when the need arises — but that hasn’t happened yet.
So Greenpeace is talking about an imaginary $1 billion facility, to be built sometime in the future. Apple appears to be talking about the $500 million facility that’s up and running today.
That makes the difference less stark. Using Greenpeace’s same metrics, that would put the current Maiden facility at 50 megawatts.
Even so, Greenpeace’s Gary Cook questions Apple’s power consumption figure. “It seems low even for the size of the existing shell they have there if you look at other facilities” he says. “I would expect as they continue to ramp up that facility, it will continue to go north.”
What he’d like to see is a commitment from Apple to keep buying renewable energy, even as it expands the data center.
That’s what Google has done, he says. “They’ve actually put data centers in locations where the grid’s not very green, but hey have matched this with long term 20 year contracts for big chunks of wind,” he says. “Companies like Apple and Microsoft could be doing this as well. There are wind developers who would like to bring their power to market. If they had forward-looking companies signing long-term contracts, that would help bring more power on the grid.”
