These days, it seems staying green and environmentally friendly is on the top of everyone’s list. People drive hybrids, recycle their gadgets (the non-sentimental ones, anyway) and conserve where they can. To help consumers, and the planet, Nokia, Samsung, Sony Ericsson, Motorola and LG Electronics have teamed up to make a common rating system for energy chargers. Believe it or not, when you unplug your BlackBerry, Touch Diamond, iPhone or any other phone from the charger, it will still draw electricity unless you unplug the charger from the wall unit. We all know just how much energy we can drain being gadget freaks, but by removing your charger from the wall when your gadget is done charging, you can save tons of energy. “If the more than three billion people owning mobile devices today switched to a four- or five-star charger, this could save the same amount of energy each year as produced by two medium sized power plants,” Nokia said in a statement. So, look for energy saving chargers when considering a replacement or a spare. Now all we can hope for is that manufacturers can agree on one universal charger for all gadgets and devices, but it seems hope is all we’re stuck with for the moment.
