Unplug Chargers When Not In Use
One tip I recently became aware of was that unplugging chargers (i.e. cell phones) when not in use can save a good bit of power.
When you think about it, this really makes sense. Because the charger typically has a power converter on it which converts the wall current into what the device needs, whenever the charger is plugged in the current is being converted, regardless of whether the device is on the other end. The end result is power constantly being consumed. This same logic applies to virtually any device which utilizes a charger, laptops for example.
So when your device is fully charged, unplug the charger. Doing so not only saves energy, but can save you some money as well.
