As green IT plans persist through 2010, I'm starting to receive questions from IT infrastructure and operations professionals — particularly data center managers — about the use of cleaner energy sources (e.g. wind, solar, fuel cells, hydro) to power their data center facilities. So when Google recently announced its purchase of 114 megawatts of wind power capacity for the next 20 years from a wind farm in Iowa, I got excited, hopeful of a credible example I could refer to.
But as it turns out, Google will not be using this wind energy to power its data centers. . . yet. Despite Google stating that the wind capacity is enough to power several data centers, their Senior Vice President of Operations, Urs Hoelzle, explains that, "We cannot use this energy directly, so we're reselling it back to the grid in the regional spot market." I confirmed this in electronic conversations with two other industry insiders, Martin LaMonica (CNET News) and Lora Kolodny (GreenTech), who also covered the announcement.
And it's unfortunate since Google's $600 million data center in Council Bluffs, Iowa could likely benefit from the greener, and possibly cheaper, wind energy. But Iowa is a large state and it's likely that distribution of the wind energy is an issue since the Council Bluffs data center appears to be well over a 100 miles away from their wind farms several counties away.
