How Google’s Data Centers Use Renewable Energy
We’ve previously covered Google’s announcement of Power Purchase Agreements (PPAs) to add wind power to utility grids that support its data centers in Council Bluffs, Iowa and Pryor, Oklahoma. Google says it expects these two agreements alone to account for 15 percent of its company-wide energy usage by the end of 2012, pushing its overall renewable mix to 35 percent. As part of its new initiative on discussing its energy usage, Google has put together a video that provides a user-friendly overview of its PPAs and how renewable energy fits into its data center strategy – including why it doesn’t currently deploy wind turbines or photovoltaic solar arrays at its data center campuses. This video runs about 2 minutes.
Very compelling, though this didn’t really answer the question about where Google is powering their data centers from.
