AT&T offers low energy chargers made with recycled plastic, details energy and water efficiency measures
AT&T is offering its customers mobile phone chargers made with housing that consists of at least 30% post-consumer plastics, reports Environmental Leader.
The chargers, available for wall sockets and cars, is rated Energy Star 5, and meets California’s Energy Commission 2013 efficiency standards, which specify reduced “vampire draw” when the charger is plugged in but not connected to a mobile device. According to AT&T, the chargers consume less than 0.3w of energy in this state. Over a year, the chargers in this state uses only the energy required to keep a 100w light bulb on for a day, AT&T said.
The charges will support all mini USB sockets, which means most Android smartphones. It won’t work with iPhones or tablets though.
Meanwhile, AT&T claims that it has reduced the energy per volume of data on its network between 2010 and 2011 by 17%. By 2011, every terabyte of data transported on its network required 334kWh of energy, compared to 415kWh in 2010 and 654kWh in 2008.
The operator also revealed it is now targeting water savings with an initiative with the Environmental Defense Fund.
“AT&T began a process to better understand the company’s water footprint by looking at our 2010 water usage data. From our analysis, we discovered that out of thousands of company sites, approximately 125 facilities accounted for almost half of our 3.4 billion gallons of water usage from municipal and commercial sources,” the operator said. “Since that assessment, we’ve heightened our efforts to identify water-savings opportunities. With EDF’s help, we are now putting into place several pilot programs to test and measure the real-world impact of strategies to increase the efficiency of our water, chemical and energy use in our cooling systems.”
AT&T has selected a group of pilot locations to test new technologies and enhanced operational procedures to reduce water usage. These efforts include the installation of high efficiency softeners to achieve near-zero blow down, maximising the use of free air cooling in order to reduce the need for cooling towers, and installing metres to see where water is flowing within systems. The company has collected baseline data on these sites over the summer and plans to develop key performance indicators for water and electricity use.
