Although we can do more for the planet at our house, we try do to our share. We bought a hybrid back in 2005, we recycle every possible bit of paper and plastic we can to reduce what goes in landfills and we swapped out over 45 incandescent bulbs with CCFLs almost two years ago. Unfortunately, all that means nothing when you step into the home office where there’s bound to be several handsets, three computers and various other gadgets sucking down electricity.
I’ve tried to unplug devices once they’re fully charged, but my good intentions often go awry in a few days as I get busy and forget. Why is that a problem? Many AC adapters and device chargers simply don’t stop using electricity when their host device is fully charged. Like a digital vampire, they continue to drain a wee bit of juice when they really don’t need to. Hopefully, that’s all about to change for the better in the cellular handset industry.
Yesterday, five major handset manufacturers launched a new five-star rating system for phone chargers. The range is from zero to five, with zero being the most inefficient while a five is considered top-notch. I liken it to the EnergyStar system we have here in the U.S. A zero rating means that the chargers continues to use draw than .5 Watts from the grid after the phone battery is fully charged. How do you get a five? Bring that power draw down to 0.03 Watts or less.
Nokia, Motorola, LG, Samsung and Sony Ericsson are the
final five (sorry BSG fans) handset makers to adopt the system and Nokia says "Around two thirds of the energy used by mobile devices is lost whenchargers are disconnected from the phone but left plugged into the mains." Conspicuously absent, at least to me anyway, are Apple, RIM, and HTC. Let’s hope they see the light and join in the green movement soon. Nokia offers plenty of information on the new rating system at a dedicated site on the topic.
