Nokia, Samsung, Motorola, LG, and Sony Ericsson probably don't see eye-to-eye on very many topics, but thankfully, they can all agree that Planet Earth is worth saving (or, at the very least, they can all agree that getting hated on by Greenpeace sucks). The five handset juggernauts have announced a common five-star rating system for phone chargers, making it easier for buyers to figure out which chargers consume the least energy; adapters that have features like automatic standby when the phone is finished charging
will be awarded higher ratings. Nokia's been saying for some time that a ridiculous amount of energy is wasted every year by chargers that are idling their watts away plugged into fully-charged phones, so this could be a major step toward getting charger manufacturers to produce more advanced models en masse.
