Do you Know Why do we see so many Pylons because of Electricity is used as a way of moving energy from place to place. It can take energy from burning coal in a power station into your home. Electricity is required for so many things in our homes and at our place of work that we need a way of getting the energy to travel. Giant masts called pylons have been erected all over country which are connected by powerful electrical cables. Energy travels down these cables at about 2,50,000 kilometers a second which is almost as fast as the speed of light.
