The giant electric pylon in this photo looks a little bit like a space alien marching across the land. The pylon supports
heavy electric cables that carry electricity from the transfer station in the background to a distant city. The electricity
that flows through wires in your home probably travels through cables on pylons like this one. Did you notice the
other source of electricity in the photo? The brilliant bolt of lightning is a huge discharge of electricity from the
clouds to the ground. Where do these two sources of electricity come from? In this chapter, you’ll find out.
