How IBM with its Smarter Planet initiative, GE, Cisco are creating smart infrastructure that saves energy. This reduces carbon dioxide emissions by reducing traffic congestion in cities like Stockhom, uses less water at plants, uses less energy for rail locomotives. These companies use technoloical advances in sensors to monitor use and advaced software to control usage. The huge stimulus spending in these areas creates new opportunities that companies are pursuing aggressively. One Dept of Energy project in Washington state using IBM technology showed that peak loads on utility grids can be reduced by 15%. Nationally such an advance in the U.S. over a 20 year period would eliminate the need for 30 coal-fired plants. IBM has a project in Norway for distribution with the largest food supplier using tracking software to optimize shipments and reduce spillage.
