Dell is not only working day-in-day-out to beat market leader HP, but also to protect environment from green house gases. Today the firm announced that it is now powering 100 percent of its 2.1 million square-foot global headquarters campus, home to more than 10,000 employees, with 100 percent green power, the latest step in meeting the company’s 2008 carbon neutral commitment. Dell is using all of the power generated from Waste Management’s Austin Community Landfill gas-to-energy plant, meeting 40 percent of Dell headquarters’ campus power needs. The remaining 60 percent comes from existing wind farms and is provided by TXU Energy.

Operational initiatives to increase efficiency and reduce electricity use already implemented on Dell’s central Texas campuses are expected to save the company nearly $2 million annually in operating costs and cutting CO2 equivalent emissions by nearly 12,000 tons per year.

Dell also announced today it is increasing green power use for its Austin Parmer Campus, provided by Austin Energy, from eight to 17 percent. The company is a leading participant in Austin Energy’s GreenChoice power program. Dell also is powering its Twin Falls, Idaho, facility with 100 percent green power, 97 percent of which is wind power and three percent solar.
