We are going to tell you a lot about power plants. Electricity comes from a place called a power plant. Power plants can't make electricity without coal.
Boats come from rivers and canals to bring coal to the power plants.
In a power plant, steam pushes against a big wheel called a turbine. The steam pushes the turbine around and around. Hundreds of years ago, people used fast rivers to turn their mills to grind wheat. Nowadays, people use coal to turn mills. I hope you know a little more about power plants now.
