The greatest invention of all time, without electricity the world would stop turning. Electricity can simply be described as electrons running through an element that leads electricity, such as a copper wire, a transistor, a resistor or a capacitor. Electricity can be "stored" in so called batteries or capacitors. Without electricity we wouldnt have TV, cars, electric toothbrushes (duuh?), computers nor electric chairs (thanks John Fru)... And that would suck, wouldn't it?
I turned on my electric lamp, sat down on the couch, turned on the TV with my electric remote control, and electrecuted my friends with the stun gun (needs electricity) so I could watch my stories!
