The European Commission identified several key roles where ICT can be used to achieve these goals.
For instance, “smart” electricity grids and metering systems improve distribution of electricity to areas where they are most needed, thus reducing wastage of power that could amount to millions if not billions of dollars. Likewise, water management systems can also be controlled using intelligent ICT systems in order to distribute just the right amount of potable water to different locations. Sewer systems can also be monitored and maintained to reduce pollution, which costs money to manage through traditional means.
Buildings, which account for nearly 40 percent of all power being used, could cut down consumption by as much as 20 percent if automatic lighting and air conditioning systems are put in place.
