If just 10% of the worlds cell phone users unplugged their phone chargers when their battery is full, they would save enough power to power 600,000 homes for an entire year. So imagine if just 10% switched to recharging their phones using alternate means. Such as a solar charger. You can pick one of these up for about $20-30 (Ebay) or more for a product such as Solio’s chargers.

The way they work is that the charger has it’s own battery which you can charge with the sun (or by plugging it in to the wall if you wish). You can then transfer this charge to your phone any time you want to. This type of charger is very handy not just for energy saving purposes but also in emergencies such as if you are in a remote area.
