Coal to Electricity
Coal is a fuel that is found in the ground. It is made of the remains of plants that died millions of years ago. Soil piled up on top of the remains and that weight compacted it into a more dense material, called coal. The energy in the coal came from the sun and was stored in the plants. When the coal is burned, it gives up that energy as heat. The coal's heat energy can then be turned into electrical energy. This happens at a power plant.
