As technology has advanced, we have come up with ways to produce and use more energy, and have come up with many different ways of doing so. Most of what I know of using energy for households or factories or big machines is that they use electricity, as a way to convert fuel, heat, wind, light, etc. into electricity, and then into motion, heat, light, sound, etc. Scientists have come up with heaps of different ways of producing energy in the form of electrity, but will electricity be the main form of energy transmission in the future? I have tried to research into this, but haven't had any luck. Does anyone know whether or not there is viable alternatives to electricity that might be used in the future because of particular benefits?
