A crash course in changing the world.
Celllphones. They are something that almost everyone has. Some teens are texing non stop! Some take up a lot of power especially if they have to be charged everyday. They may not seem like a lot of electricity but if you add up how many people have cellphones then the power usage is quite alot. If all cellphones had solar panels on the back, front, keys and around the screen then all you would have to do is leave your phone by a sunny window to charge it. Only on rainy days would we have to use your charger. This could potentionally save a lot of power and might also be a lot easier to charge your phone!
