The International Herald Tribune reported an interesting trend at the Mobile Congress in Barcelona earlier this month: "green" cell phones made of recycled and biodegradable materials that require less energy than regular cell phones.
Until now, there have been few environmentally-friendly cell phone options available to consumers. This seems, however, to be quickly changing! Nokia, the Finland-based manufacturer that made one of every 3 cell phones sold last year, introduced "green" features on a number of its mobile products, including sensors that detect natural light to allow the phone to save energy, and chargers that beep when they are fully charged, cuing the owner to unplug them from the wall socket.
