We use lights to light our rooms, chargers to charge our phones and well i do not have to go any further technology is around us...all around! We are using power to write blogs, and pretty much just to go on Urgent Evoke we need to use power. An effective way to using power less is, when reading read in the day time and not use up any lights in your room, if it is sunny outside crack open the window and let oxygen and light in. When not using the phone or the computer or any techology unplug it. It will be a pain to plug-then-un-plug, yet when you are saving power and saving energy and saving money.
