Dell relies on various forms of renewable energy for about one-third of its power requirements at its American facilities and now wind power is responsible for even more of their energy needs.

The Dell customer service center in Oklahoma City has just contracted OG&E to provide power for 100 percent of the building’s needs.

This will make for the second Dell facility to rely completely on renewable energy. The Dell headquarters in Round Rock, Texas relies on wind power for 60 percent of its needs and gas energy conversion for the remaining 40.

Dell is technically 100 percent powered by wind power since they purchase sufficient renewable energy credits.

Part of Dell’s long-term environmental agenda is to cut greenhouse gas emissions by 40 percent by 2015.
