How to Go on A Carbon Diet

摘要

Workers at Toyota Motor's 20,000-sq.-ft. data center in California may have been puzzled by the strange metal cart being pulled through the aisles over the past year. The high-tech trolley was developed by IBM to sniff out wasted energy using heat-seeking sensors that collect a floor-to-ceiling, three-dimensional view of a room in cool blues and hot reds. It sees "in color exactly where the heat is coming from so you can address it," says Wayne Balta, vice-president for corporate environmental affairs at IBM. The machine has helped IBM trim its own energy use by 5.4 percent and has saved nearly 350,000 tons of carbon dioxide emissions for clients, he says.
