Something that I use that could be powered differently or manipulated to save energy would be my cell phone. My suggestion would be that we invent a solar panel that could capture energy from the sun, and then create a large cell phone dock that would be powered by this solar energy. I know that this would have to be a gradual process, but eventually all cell phones could be converted so that they could have a slot to dock in this solar powered device. Since these docks would have multiple cell phone ports, we could install them in the common rooms of colleges so kids could have easy access to it. At homes, one solar powered dock would be sufficient to power all the phones a family has. In cities, we could have one dock that would charge all of the residents’ phones on the floors. Eventually the system will be able to have each person enter a personal code to dock and undock their phone so no phones will get stolen.
