The cable industry is marching towards a greener future, and on that note Cox Communications reduced the carbon footprint of its San Diego headquarters with the recent addition of fuel cells.

Cox said two separate 400-kilowatt (kW) installations were completed at the company's San Diego headquarters. One fuel cell will provide all of the electrical load for one building, while the second fuel cell will provide nearly 60 percent of the electrical requirement for the main building.

By adding the fuel cells, Cox said it would generate enough onsite power equivalent to planting 618 acres of trees, powering 602 homes annually, and saving nearly 1 million gallons of water a year.

"Cox Communications is extremely proud to be able to make such a positive impact on our environment and help encourage other businesses to implement eco-friendly initiatives," said Bill Geppert, senior vice President and general manager of Cox Communications' San Diego operations.

The fuel cell project was part of the nationwide Cox Conserves program that was designed to reduce the company's carbon footprint by 20 percent by 2017, and promote eco-friendly behavior among its employees, communities and other corporations. Cox has its own Web site that's dedicated to its green initiatives.

Last year Cox Communications completed its first commercial solar installation in Avondale, Ariz.

Also last year, the Society of Cable Telecommunications Engineers announced its Smart Energy Management Initiative (SEMI) to facilitate "green" best practices in the industry, including solar voltaic.
