Mobile manufacturers agree rating system for chargers

LG, Motorola, Nokia, Samsung and Sony Ericsson have launched an energy rating system for chargers, making it easier for consumers to choose the most energy-saving devices. The new rating system indicates how much energy each charger uses when left plugged into the wall socket after charging is completed. The ratings covers all chargers currently sold by the five companies, range from five stars for the most efficient chargers down to zero stars for those consuming the most energy. Ratings will be shown on each manufacturer's web site. [Nokia press release]
