This means three of the five massive computing facilities that will drive the company's worldwide social network in the years to come will run use only renewable energy. But Peter Freed, who helps oversee renewable energy efforts at Facebook, isn't entirely pleased. Buying clean energy, he says, remains far too difficult.
"It should be easier to get these kinds of things done," he says, "and we're seeing an increasing number of companies that want to do them."
According to Freed, it took Facebook more than a year to arrange a wind power deal for the new data center slated to open in Fort Worth, Texas, next year. And making this kind of thing happen in Texas is far easier than in most other states. Texas is a deregulated energy market, where companies are free to chose their own power provider.
