4,200 Energy Efficiency Projects Saved AT&T; $44 Million Last Year
AT&T; announced today that because of 4,200 energy efficiency projects installed at company facilities during 2010, it saved $44 million in annual energy costs. The projects included things like installing desktop power management software on 169,000 computers, a measure that generated $614,000 in savings alone, and installing LED light bulbs at over 1,100 cell sites. The company also removed switches at 11 central office sites, which reduced power consumption by more than 300,000 kWh network-wide.
GreenBiz reports that AT&T; energy director John Schinter "declined to disclose the amount the company invested in the more than 4,000 projects to realize the savings, but said each had a payback period of one to four years."
AT&T; details the progress of its online energy management training program for AT&T; corporate real estate managers:
In 2008, AT&T; established an energy intensity metric based on kWh per terabyte of data carried on their network and set a goal for 2009 to reduce that intensity by 15 percent. In 2009, AT&T; achieved a 23.8 percent decrease in energy intensity using 498 kWh per terabyte of data carried on their network. For 2010, AT&T; set a goal to further reduce energy intensity by an additional 15 percent as compared with 2009's KWh per terabyte of data figure.
Generally, AT&T;'s 2010 efficiency measures build on efforts started in 2009 with its Energy Scorecard, which the company says is used to grade energy performance at its 500 top energy-consuming facilities. Many of the 4,200 projects from last year were first identified by real estate managers in that program.
"We provided our employees with the needed tracking tools, training and incentives for them to be successful in their tremendous efforts to reduce AT&T;'s energy use and realize significant cost savings," said Schinter.
The company participated in the Environmental Defense Fund's Climate Corps program last year. "Through our Climate Corps program, we were able to help AT&T; identify a potential savings of 80% in electricity usage associated with lighting use across more than 100 million square feet of space," said Victoria Mills of EDF. "This underscores that a compelling business case for energy efficiency can be made at any company."
(It's encouraging that AT&T; is not the only big corporation to have adopted this lesson lately.)
