AT&T Launches New Energy-Saving Software

Company Deploys 1E NightWatchman to Reduce PC Power Consumption

Dallas, Texas, AT&T Inc. (NYSE:T) today announced it is launching the NightWatchman® PC power management solution from 1E on 310,000 desktop computers across its domestic operations to help improve energy efficiency. Powering down corporate PCs during non-work hours is expected to save AT&T more than 135 million kilowatt hours of electricity a year and eliminate 123,941 tons of carbon dioxide emissions — equivalent to the electricity required to power 14,892 homes.

“For the IT function at AT&T, our emphasis is doing more work with less energy and using products that are minimally impacting the environment,” said Rick Felts, AT&T senior vice president of Information Technology Operations. “Installing a power management solution builds on our ongoing efforts to drive energy efficiency inside our facilities. It also allows us to systematically and safely power down PCs while at the same time not compromising our ability to perform software updates as needed.”

Sumir Karayi, chief executive officer of 1E, said: “1E is proud to work with AT&T on this project. The deployment of NightWatchman reflects AT&T’s commitment to find sustainable business solutions that not only help the company reduce costs but also help reduce environmental impact. Since its inception eight years ago, NightWatchman has been deployed on more than 2.5 million machines worldwide, helping to drastically reduce CO2 emissions globally.”

Reducing energy consumption during non-peak hours is one way AT&T is striving to minimize the environmental impact of its operations. The company is working to enhance energy performance and reduce energy consumption in company buildings, data centers, IT systems and networks. AT&T has begun to use alternative energy sources such as wind and solar power, and it conserves natural resources through waste reduction, recovery and recycling efforts. AT&T also helps customers further manage their own environmental impact through intelligent use of AT&T products and services, such as teleconferencing, video conferencing and other broadband applications.
