What happens to electricity after it is used?
It is just converted from one form to another, from chemical energy in batteries (or mechanical energy in turbines) to electrical energy and then to heat and light. This energy is used by devices to do work. The energy converts into heat, light, sound and mechanical energy or whatever you choose to do.
Does unplugging appliances save electricity?

How did we survive without electricity?
Without electricity, you had to cook over an open fire, such as on a metal stovetop or over a fireplace. There weren’t any appliances either, so bakers relied on labour-saving devices like manual mixers to make batter and dough. Ovens, for making bread and other baked goods, relied on firewood-powered fires.
Does an empty plug socket use electricity?
The answer is that an empty plug socket isn’t using any electricity, because the current doesn’t flow unless there’s a plug completing the circuit and an appliance switched on. So you really don’t have to go round turning every socket to the off position, even when it’s a socket in an empty room.
